Reusable bottles (e.g., water bottles), however, present a significant challenge for users in maintaining hygiene. For example, without regular cleaning, biofilm can buildup and bacteria can grow on the inside of reusable bottles - especially when non-water liquids are stored. Conventional cleaning methods, such as handwashing, are often inconvenient, leading to inconsistent and / or infrequent cleaning. Home dishwashing appliances, while effective at cleaning, are not always accessible or efficient for users, and / or can take multiple hours. Accordingly, a need exists for automated cleaning systems designed for reusable bottles.SUMMARY|0003| In some embodiments, an apparatus includes a housing defining a cleaning chamber, a first holder disposed in the cleaning chamber, a second holder disposed in the cleaning chamber, a fluid circulation system, and a controller. The first holder is configured to hold a liquid container in the cleaning chamber and is automatically adjustable based on a shape of the liquid container. The second holder is configured to hold a lid of the liquid container in the cleaning chamber. The fluid circulation system includes a heat source and a reservoir configured to contain a cleaning substance. The controller is configured to cause, in response to a signal indicative of a door of the cleaning chamber being closed, the fluid circulation system to provide a pressurized flow of a heated cleaning solution to (i) a first cleaning device disposed in the cleaning chamber and configured to clean the liquid container, and (ii) a second cleaning device disposed in the cleaning chamber and configured to clean the lid of the liquid container.323852021 1Agent’s File Ref.

[0039] Referring now to the drawings, FIG. 1 illustrates a cleaning system 100 according to an embodiment. The cleaning system 100 can be, for example, an automated cleaning system323852021 6Agent’s File Ref. NMCL-001 / 01WO 358969-2003 for cleaning liquid containers such as reusable bottles (e.g., water bottles). The cleaning system 100 can be designed for implementation in public spaces. For example, the cleaning system 100 can be deployed in public areas like schools, gyms, airports, etc. In some implementations, the cleaning system 100 can be used alongside water bottle fdling stations and can utilize existing plumbing infrastructure to clean reusable containers such as water bottles. In some embodiments, the cleaning system 100 can provide a high-pressure cleaning system with temperature-controlled washing cycles and rinsing cycles that use minimal water while ensuring comprehensive cleaning. In some implementations, the cleaning system 100 can autonomously (or at least semi-autonomously) clean a variety of liquid containers - including lids, caps, straws, etc. thereof - in an efficient manner and in a time that is significantly less than, for example, a commercial dishwashing appliance.[0040| As shown in FIG. 1, the cleaning system 100 (also referred to herein as “system 100”) can include a housing 101, one or more holder(s) 130, one or more cleaning device(s) 145, a fluid circulation system 160, and a controller 180. In some embodiments, the cleaning system 100 can also include an optional disinfection device 175.[0041| The housing 101 of the cleaning system 100 can be any suitable shape, size, and / or configuration. The housing 101 provides the structural framework for supporting, protecting, and separating the internal components. The housing 101 can be formed from any suitable material or combination of materials. In some embodiments, the housing 101 can be formed from galvanized steel, stainless steel, aluminum, polymers, composite materials, and / or the like or combinations thereof. For example, in some embodiments, it may be desirable to form the housing 101 or at least portions of the housing 101 from non-corrosive materials such as stainless steel. As described above, the cleaning system 100 can be suitable for deployment in public areas such as buildings, schools, gyms, etc. As such, the housing 101 can include one or more features configured to facilitate the mounting of the system 100 to an existing infrastructure such as a wall or the like. Such feature(s) can include cleats, brackets, fasteners, and / or the like. Alternatively, in some embodiments, the cleaning system 100 can be a freestanding system that does not include such mounting features. Rather, such embodiments (e.g., housing components, etc.) can include one or more features that allow the system 100 to be secured to the ground, floor, or surface.[0042 J The housing 101 is configured to house one or more components of the system 100. In some embodiments, the housing 101 can include multiple portions, sections, regions, compartments, etc. For example, the housing 101 can include a first portion that forms a323852021 7Agent’s File Ref. NMCL-001 / 01WO 358969-2003 cleaning chamber 120 and a second portion that houses and / or stores various components of the cleaning system 100 such as, for example, the fluid circulation system 160 (or at least a portion thereof), the controller 180 (or at least a portion thereof), and / or any other suitable components.[0043 J The cleaning chamber 120 can be formed by or included in, for example, an upper portion of the housing 101. The cleaning chamber 120 defines and / or forms a volume into which a liquid container can be positioned and cleaned. In some embodiments, the cleaning chamber 120 can be a sealed or at least partially sealed (or sealable) chamber configured to prevent a fluid (e.g., a cleaning solution, water, etc.) from exiting the cleaning chamber 120 during a cleaning operation. For example, the cleaning chamber 120 can be a self-contained that is disposed in and / or supported by the upper portion of the housing 101. Alternatively, the cleaning chamber 120 can be at least partially formed by or integrated into the structure of the housing 101.[0044J The cleaning chamber 120 can be any suitable shape, size, or configuration. In some embodiments, for example, the cleaning chamber 120 can have and / or can form an enclosed cylindrical shape. Although not shown in FIG. 1, the cleaning chamber 120 includes a door assembly configured to provide access into an inner volume of the cleaning chamber 120. In some embodiments, the door assembly can be and / or can include a rotational door that can be rotated between an open position in which an interior of the cleaning chamber 120 is accessible, and a closed position in which the cleaning chamber 120 is sealed or at least partially sealed. Such a configuration can allow the door to rotate relative to and within the housing 101. In other embodiments, the door can be and / or can include a linearly movable door that can be translated or slid between the open configuration and the closed configuration. With either the rotational or the linearly movable configuration, the door can include or can be coupled to one or more wheel assemblies, carriages, sleds, etc. configured to allow the door to be moved with a desired set of characteristics. In still other embodiments, the door can have a hinged configuration in which the door (or at least a portion of the door) can be pivoted about one or more hinge axis.[0045[ The door can be formed from a relatively clear or transparent material allowing visualization into the cleaning chamber 120. For example, the door can be formed from a clear, acrylic material or other suitable polymer. In some embodiments, the door can include one or more coatings or can be formed from a material that is at least partially opaque. For example, the cleaning system 100 can include a disinfection device 175 that can be configured to expose323852021 8Agent’s File Ref. NMCU-001 / 01WO 358969-2003 the interior of the cleaning chamber 120 to UV light (e.g., UV-C radiation). In such embodiments, the UV-C radiation can clean or sterilize the interior of the cleaning chamber 120 while the coating or tint of the door can limit or substantially prevent the UV radiation from escaping the cleaning chamber (e.g., via the door). Such an arrangement can protect a user from undesirable exposure to such radiation.[0046| The door assembly can include a locking mechanism configured to at least temporarily maintain the door in the closed configuration. Such a locking mechanism can be and / or can include a latch, a clamp, a stopper, a magnetic lock, and / or the like. In some instances, the locking mechanism can provide the user with feedback (e.g., haptic feedback) that the door is fully shut. The locking mechanism can be, for example, electronically and / or mechanically controlled. With an electronically controlled locking mechanism, an electrical signal can actuate the locking mechanism to a locked configuration when the door is in the closed configuration (e.g., automatically). In addition or as an alternatively, the locking mechanism can be and / or can include a mechanically controlled locking mechanism that can be actuated or locked based at least in part on a position of the door (e.g., a portion of the door can engage the locking mechanism as the door is moved from the open configuration to the closed configuration). In addition, the door assembly can include a switch or sensor that can detect a state, configuration, or position of the door assembly. For example, such a switch or sensor can detect whether the door is in the open or closed state and can communicate a signal associated with the state to the controller 180. As described in further detail herein, the controller 180 can be configured to prevent a cleaning operation from being performed while the door is in the open state or configuration.(0047| As shown in FIG. 1, the cleaning chamber 120 also includes or is coupled to a drain assembly 123. The drain assembly 123 is configured to covey used fluid (e.g., a cleaning solution, water, etc.) from the interior of the cleaning chamber 120 to, for example, an existing plumbing infrastructure at the site of installation. For example, the cleaning chamber 120 can include a drain plate that can define one or more openings that allow a flow of fluid out of the cleaning chamber 120. The drain assembly 123 can further include, for example, one or more removable filters configured to filter out larger particulates from the flow of wastewater through the drain assembly 123. The drain assembly 123 can be configured to provide relatively easy access to the filter (e.g., via a drain drawer or other structure removably coupled to the housing or cleaning chamber 120).323852021 9Agent’s File Ref. NMCL-001 / 01WO 358969-2003

[0048] The drain assembly 123 can include and / or can form an outlet of the cleaning chamber 120, which is otherwise sealed or substantially sealed to limit and / or substantially prevent undesired splashing or an undesired from of fluid outside of the cleaning chamber 120. In some embodiments, the drain assembly 123 can further include or can be configured to function as a vent that allows a flow of gas into or out of the cleaning chamber 120. For example, in some implementations, it may be desirable to provide a pressurized flow of cleaning solution, water, or other liquids into the cleaning chamber 120. By providing a vent, a buildup of pressurized gas in the cleaning chamber 120 can be limited or substantially prevented by allowing a flow of gas out of the cleaning chamber 120. In other implementations, the system 100 can include a blower or the like configure to provide a flow of air (or gas) into the cleaning chamber 120 to, for example, dry the liquid container (bottle) secured in the cleaning chamber 120. In such implementations, venting the cleaning chamber 120 (e.g., via the drain assembly 123 or any other suitable venting mechanism) can limit and / or substantially prevent a buildup of pressure in the interior of the cleaning chamber 120.

[0049] As described above with reference to the door, the drain assembly 123 can include one or more switches, sensors, and / or the like configured to detect a state, position, and / or presence of the drain assembly 123. For example, such a switch or sensor can detect whether the drain assembly 123 is fully or correctly coupled to the housing 101 and / or cleaning chamber 120 or whether the filter or other portion of the drain assembly 123 is experiencing reduced flow (e.g., due to a clog or the like). As described in further detail herein, the controller 180 can be configured to prevent a cleaning operation from being performed while the drain assembly 123 is not fully or correctly in a desired position to drain the cleaning chamber 120.

[0050] The one or more holder(s) 130 of the cleaning system 100 is / are disposed in the cleaning chamber 120. The cleaning system 100 can include any number, type, and / or arrangement of holders 130 configured to receive one or more components of a liquid container and to at least temporarily hold, secure, and / or retain the components of the liquid container (e.g., during a cleaning operation). For example, in some embodiments, the cleaning system 100 can include at least one holder configured to receive and at least temporarily hold a liquid container such as a reusable bottle (e.g., water bottle). A discussion of the holder 130 configured to hold a liquid container such as a reusable water bottle (also referred to herein as a “first holder” or “bottle holder”), is provided below followed by a discussion of additional and / or other holders that may be included in the cleaning system 100.323852021 10Agent’s File Ref. NMCL-001 / 01WO 358969-2003

[0051] As shown in FIG. 1, the first holder 130 is disposed in the cleaning chamber 120 and can be disposed in a desired position relative to, for example, a corresponding cleaning device 145. In some embodiments, for example, the first holder 130 can be aligned or disposed substantially above a corresponding cleaning device 145, thereby allowing the cleaning device 145 to direct a flow of fluid (e.g., cleaning solution, water, etc.) to or toward a liquid container held by the first holder 130, as described in further detail herein.

[0052] The first holder 130 is configured to receive and at least temporarily hold liquid containers of various shapes, sizes, and / or configurations. For example, the first holder 130 can include and / or can form a clamping device or the like that can exert a force on the liquid container to secure the liquid container in the cleaning chamber 120. Such a clamping mechanism can include mechanically actuated arms that can grip the liquid container (e.g., via a force exerted by a spring or the like). In some embodiments, the clamping mechanism can include a gripping portion formed from or including a relatively soft material configured to increase an amount of friction associated gripping the liquid container. In some instances, a mechanical actuation may be advantageous due to the wet environment of the cleaning chamber 120. Alternatively, such a clamping mechanism can be electrically or electronically controlled using motor(s), rack and pinion system(s), and / or the like. In such embodiments, the holder 130 can include a sensor (e.g., an optical sensor, laser sensor, and / or other suitable sensor) configured to detect, sense, and / or measure a size and / or shape of the liquid container, which in turn, can be used to adjust the holder 130 based on the sensor data. In other embodiments, the holder 130 can be a funnel or other static structure that can receive the liquid container while exposing a portion of the liquid container from which the user drinks (e.g., the threaded portion, open portion, top portion, etc.) to the cleaning device 145 or at least a flow of fluid from the cleaning device 145.[0053J As described above, the first holder 130 can be aligned with or otherwise can be in a desired position relative to the corresponding cleaning device 145. In addition, the first holder 130 can include a self-centering mechanism or feature configured to center or substantially center liquid containers of various sizes and / or shapes relative to the corresponding cleaning device 145. Such an arrangement can ensure a desired portion of the liquid container is exposed to the flow of fluid from the cleaning device 145 allowing at least the desired portion to be cleaned.

[0054] In addition to the liquid container holder 130 (e.g., first holder), the cleaning system 100 can further include holders 130 configured to receive and / or hold, for example, a lid323852021 11Agent’s File Ref. NMCL-001 / 01WO 358969-2003 associated with the liquid container, a straw, a mouthpiece, and / or any other suitable component of associated with a liquid container. For example, in some embodiments, the cleaning system 100 can include a holder configured to receive and at least temporarily hold and / or secure a lid of a corresponding liquid container (also referred to herein as a “second holder” or “lid holder”). As described above with reference to the first holder, the second holder 130 can be disposed in the cleaning chamber 120 in a position that is aligned with a corresponding cleaning device 145, allowing the corresponding cleaning device 145 to direct a flow of fluid (e.g., cleaning solution, water, etc.) to or toward the lid.[0055| The second holder can be any suitable shape, size, and / or configuration. For example, the second holder can be similar in form and / or function to the first holder. In some embodiments, the second holder 130 can be a basket, cup, cage, etc. in which the lid can be disposed. Such a basket, cup, cage, etc. can be a wire mesh or the like that can allow a flow of fluid to pass through the basket, cup, cage, etc. with minimal obstruction.[0056| The cleaning system 100 can further include any other suitable holder 130. For example, in some embodiments, the cleaning system 100 can optionally include a third holder configured to receive a straw or other portion of the liquid container. In such embodiments, the third holder 130 (e.g., a straw holder) can be a basket or the like with a relatively small size to limit or restrict movement of the straw during cleaning. In other embodiments, the third holder 130 can be a clamp or other similar mechanism similar to the first holder. In some embodiments, the third holder 130 can be integrated into a corresponding cleaning device 145. For example, the corresponding cleaning device 145 can be and / or can include a nozzle onto which the straw can be positioned. In such embodiments, the nozzle can be an elongate structure with a tapered end portion that can be inserted into straws of various sizes. As such, the nozzle can engage an inner surface of the straw to both retain or at least partially retain the straw and direct a flow or jet of fluid into the straw to clean the inner surface thereof.

[0057] While various holders 130 are described above, it should be understood that additional or other types of holders are possible. As with the holders 130 described above, such alternative or additional holders can be configured to receive one or more portions or components of a liquid container and can at least temporarily hold, retain, and / or secure such portions or components in desired position(s) relative to one or more cleaning device, allowing the portions or components to be cleaned.323852021 12Agent’s File Ref. NMCL-001 / 01WO 358969-2003

[0058] The cleaning system 100 can include any number, type, and / or arrangement of cleaning devices 145 configured to receive a flow of fluid such as a cleaning solution / mixture, liquid soap, liquid detergent, water, and / or the like and to direct a flow of the fluid to or toward one or more components held or secured by the holders 130. For example, the cleaning device(s) 145 can be configured to direct a flow of fluid to one or more components of a liquid container to clean such components during a cleaning operation. For example, the cleaning system 100 can include at least one cleaning device 145 that is disposed in the cleaning chamber 120 and configured to clean a liquid container that is held by holder 130. A discussion of a first cleaning device 145 is configured to clean a liquid container such as a reusable water bottle, is provided below followed by a discussion of additional and / or other holders that may be included in the cleaning system 100.

[0059] The first cleaning device 145 can be any suitable shape, size, and / or configuration. For example, the first cleaning device 145 can be a nozzle or other device that is at least fluidically coupled to the circulation system 260 allowing the first cleaning device 145 to receive a flow of fluid. The first cleaning device 145 can be hollow or otherwise can define one or more channels, flow paths, etc. configured to convey the flow of fluid therethrough. In some embodiments, the first cleaning device 145 can include a set of outwardly extending arms that define any number of openings, holes, ports, etc. The arms can be angled upward or toward the corresponding or aligned holder 130. Accordingly, the first cleaning device 145 can receive a flow of fluid (e.g., a pressurized flow of cleaning solution, water, etc.) and can direct the pressurized flow of fluid to or toward a liquid container held by the aligned holder 130.

[0060] In some embodiments, the first cleaning device 145 can be configured to rotate or spin relative to the corresponding holder (and thus, the liquid container being held). In some embodiments, for example, the arrangement of the arms and / or the openings of the arms can result in a flow of fluid from the cleaning device 145 that causes a moment or torque operable to rotate the cleaning device 145 relative to the liquid container. Alternatively, an interior of the first cleaning device 145 can include a propeller, turbine, and / or the like such that a pressurized flow of fluid past the propeller, turbine, etc. causes rotation of the first cleaning device 145. While the first cleaning device 145 is described above as being rotated passively (e.g., by the flow of fluid therethrough), in some embodiments, the first cleaning device 145 can be actively rotated. For example, the first cleaning device 145 can be coupled to a motor or the like configured to rotate the first cleaning device 145. In some implementations, the323852021 13Agent’s File Ref. NMCL-001 / 01WO 358969-2003 rotation of the first cleaning device 145 can facilitate and / or enhance a cleaning of the liquid container.[0061| In some embodiments, the first cleaning device 145 can include one or more features configured to engage or contact a surface of the liquid container. For example, the first cleaning device 145 can include a set of brushes, bristles, rollers, wipes, tethers, and / or the like that can contact, for example, the threads of the liquid container held by the corresponding holder 130 (e.g., the first or bottle holder). In such embodiments, the first cleaning device 145 can be rotated (as described above), which in turn, can move the brushes, bristles, rollers, etc. along a surface of the liquid container. As such, these features can wipe or scrub the surface of the liquid container in conjunction with the pressurized flow of fluid (e.g., a cleaning solution or the like) being directed to the surface.[0062| The first cleaning device 145 can further include one or more features configured to clean an inner surface of the liquid container. For example, the first cleaning device 145 can include one or more openings, holes, ports, nozzles, etc. configured to direct a pressurized flow of fluid into the liquid container, thereby cleaning the inner surface. In some implementations, the rotation of the first cleaning device 145 can facilitate the cleaning of the inner surface by imparting a rotation or the like on the flow of fluid operable to direct the flow of fluid to or toward the inner surface of the liquid container (e.g., an inner cylindrical surface). In some embodiments, the first cleaning device 145 can include a nozzle or other suitable portion that can be at least partially inserted into the liquid container, thereby facilitating a cleaning of the inner surface. In some embodiments, the first cleaning device 145 can include a brush or other suitable feature that can engage the inner surface of the liquid container and that can be actuated to move within the liquid container (e.g., vertically or in a rotational direction). Such a feature can be a relatively small size allowing the feature to be inserted into liquid containers of various sizes (or with openings or mouths of various sizes).(0063] Although the cleaning system 100 is described above as including the first cleaning device 145 (e.g., a single cleaning device) configured to clean the liquid container, in other embodiments, the cleaning system 100 can include multiple cleaning devices 145 configured to clean the liquid container. These cleaning devices 145 can have the same configuration or different configurations such as any of those described above (or combinations thereof).10064) In addition to the first cleaning device 145, the cleaning system 100 can include any number of additional or other cleaning devices 145 configured to clean various components of323852021 14Agent’s File Ref. NMCL-001 / 01WO 358969-2003 a liquid container. For example, the cleaning system 100 can include a second cleaning device 145 configured to clean a lid of a corresponding liquid container. The second cleaning device 145 can be at least fluidically coupled to the fluid circulation system 160 allowing the second cleaning device 145 to receive a flow of fluid therefrom.

[0065] The second cleaning device 145 can have a configuration that is similar to or substantially the same as the first cleaning device 145 or can have a different configuration. For example, the second cleaning device 145 can include a set of arms that define a number of holes, openings, ports, etc. configured to direct a flow of fluid through the second cleaning device 145 and to or toward the lid (e.g., at least the threads of the like whether they are internal or external). In some embodiments, the second cleaning device 145 can be configured to rotate, as described above with reference to the first cleaning device 145.

[0066] In some embodiments, the cleaning system 100 can include multiple cleaning devices 145 configured to clean the lid. For example, in some embodiments, the second cleaning device 145 can be disposed below a corresponding holder 130 and configured to direct a flow of fluid upward or substantially upward toward the lid held in the holder 130 above the second cleaning device 145. As described above, in some embodiments, a holder configured to hold a lid can be a wire basket or the like that can loosely hold the lid (e.g., allowing a certain amount of movement thereof). In such embodiments, it may be desirable to include, for example, an additional cleaning device above the holder 130 to direct a flow of fluid toward the lid (e.g., from above). Such an arrangement can allow for cleaning of the lid in the event of the lid flipping over or otherwise moving in the holder 130.

[0067] The cleaning system 100 can further include additional cleaning devices 145 configured to clean other portions or components of the liquid container such as, for example, straws, mouthpieces, gaskets or seals, etc. Such cleaning devices 145 can be similar in at least form and / or function to any of the cleaning devices described above.

[0068] While the cleaning devices 145 are described above as directing a flow of fluid to or toward components of a liquid container, in some implementations, the cleaning devices 145 can also be configured to clean, for example, the cleaning chamber 120. For example, it may be desirable to periodically clean the cleaning chamber 120 to limit and / or prevent contaminants therein. In some instances, the cleaning of the cleaning chamber 120 can be performed after each cleaning cycle (e.g., after a user removes the liquid container). In other instances, the cleaning of the cleaning chamber 120 can be performed at predetermined323852021 15Agent’s File Ref. NMCU-001 / 01WO 358969-2003 intervals (e.g., after five cleaning cycles, ten cleaning cycles, twenty cleaning cycles, and / or any other number of cleaning cycles). In some embodiments, cleaning the cleaning chamber 120 (e.g., a “self-cleaning cycle”) can include directing a flow of cleaning solution, heated water, and / or the like to or toward the inner surfaces of the cleaning chamber 120.[0069J In some implementations, the cleaning devices 145 can direct the flow of fluid during a self-cleaning cycle with the same characteristics or in the same manner as the flow of fluid during a normal cleaning cycle. In other implementations, the cleaning devices 145 can perform a self-cleaning cycle with a different set of characteristics. For example, in some instances, it may be desirable to limit an amount of heat transferred to a flow of water or cleaning solution to prevent or limit possible damage to components of the liquid containers or to prevent the liquid container from being heated to a temperature that is unsafe for a user to touch. Similarly, it may be desirable to limit a pressure associated with the flow of fluid to prevent or limit possible damage to the components of the liquid containers. In some instances, however, a self-cleaning cycle can be performed at temperatures and / or pressures greater than those during the cleaning cycle. Such an arrangement can, for example, facilitate and / or enhance the self-cleaning process.[0070J The cleaning system 100 can optionally include a disinfection device 175 that can be used, for example, to clean and / or at least partially disinfect the cleaning chamber 120 (e.g., during self-cleaning). Such a disinfection device 175 can be, for example, a UV light source or the like configured to expose the surfaces in the cleaning chamber 120 to UV radiation (e.g., UV-C). UV radiation is known to kill or mitigate against microbes or microbial growth and thus, the disinfection device 175 can be used to disinfect the cleaning chamber 120. In some instances, the disinfection device 175 can be used in conjunction with or instead of the selfcleaning cycle that can be performed by the cleaning devices 145. In addition, the disinfection device 175 can be used to enhance or facilitate at least a portion of the cleaning cycle. For example, the disinfection device 175 can be activated during any portion of the cleaning cycle. In some instances, it may be desirable to activate the disinfection device 175 at an end of a cleaning cycle (e.g., during drying). As such, the disinfection device 175 can direct a disinfecting agent such as UV radiation toward the liquid container and / or components thereof to facilitate the cleaning or disinfection thereof.[0071J As described above, the cleaning system 100 includes a fluid circulation system 160 (also referred to herein as “circulation system”) that is fluidically coupled to the cleaning devices 145 disposed in the cleaning chamber 120. In some embodiments, the circulation323852021 16Agent’s File Ref. NMCL-001 / 01WO 358969-2003 system 160 can be disposed in a portion of the housing 101 outside of the cleaning chamber 120 (e.g., a lower section or the like). The circulation system 160 is configured to fluidically couple to a water supply such as the plumbing infrastructure at the site of deployment or implementation. In this manner, the circulation system 160 is configured to receive a flow of water from a water source and to provide a pressurized flow of water (e.g., heated or unheated) to the cleaning devices 145 for the purpose of cleaning liquid containers and / or components thereof disposed in the cleaning chamber 120. For example, water can be received from a standard wall connection with a pressure of about 10-80 pounds per square inch (psi) and with a flow rate of about 1-2 gallons per minute (gpm).(0072) As shown in FIG. 1, the circulation system 160 includes at least a reservoir 165 and a heater 170. The circulation system 160 can also include an optional pump 161. Although not shown, the circulation system 160 can further include any suitable plumbing, piping, valves, and / or the like configured to direct a flow of fluid through the various portions of the circulation system 160 (e.g., as described herein with reference to specific embodiments).[00731 The reservoir 165 can be any suitable container configured to contain or store a cleaning solution or cleaning substance. The cleaning solution or cleaning substance can be, for example, a liquid cleaner such as liquid soap, liquid detergent, or other cleaning fluids. The optional pump 161 can be in communication with the reservoir 165 and configured to pump the cleaning substance out of the reservoir 165, allowing it to be added to a flow of water to produce a cleaning solution or mixture. The pump 161 can be any suitable pumping device. In some embodiments, for example, the pump 161 can be a peristaltic pump. In other embodiments, the pump 161 can be a gear pump, screw pump, and / or any other suitable pump (e.g., capable of pumping a relatively high viscosity fluid at a relatively low pressure).|0074 J While the cleaning solution is described as being a liquid cleaner stored in the reservoir 165, in other embodiments, the cleaning system 100 can include a solid or otherwise non-liquid cleaner and the reservoir 165 can be any suitable holder, tank, chamber, etc. In such embodiments, the circulation system 160 can be configured to circulate water or liquid through the holder, tank, chamber, etc. and past the non-liquid cleaner, allowing the non-liquid cleaner to be mixed with the flow of water (or other liquid).

[0075] The heater 170 can be any suitable heat source configured to provide thermal energy to a flow of fluid (e.g., water). For example, the heater 170 can be a water heater having a tank of relatively low volume. Alternatively, the heater 170 can be a tankless water heater or inline323852021 17Agent’s File Ref. NMCL-001 / 01WO 358969-2003 heater. In some embodiments, the heater 170 can be used with and / or can include an accumulator to enable or facilitate a flow of fluid having a desired pressure. For example, heated water can be stored at a uniform temperature in an accumulator and can provide a desired amount of hydraulic head that allows a pressurized flow of fluid to be delivered to the cleaning devices 145. In some embodiments, such a configuration enables the heater 170 to provide instant or substantially instant high-pressure, heated (hot) water, which in turn, allows the cleaning system 100 to wash multiple bottles in succession with limited wait time for water heating between cycles. The heater 170 can be configured to heat water to a desired temperature, which may be based at least in part on a cycle being performed. For example, in some embodiments, the heater 170 can heat and / or store the heated water at a temperature around 140°F or less for a bottle cleaning cycle. Alternatively, the heater can heat and / or store heated water at a greater temperature for a self-cleaning cycle (e.g., just below a boiling temperature).

[0076] The fluid circulation system 160 is configured to transition between any number of states, configurations, phases, etc. For example, the circulation system 160 can include, for example, a water heating phase, a first washing phase in which a heated cleaning solution is provided to the cleaning device(s) 145, a second washing phase in which heated water (e.g., without cleaning solution) is provided to the cleaning device(s) 145, and a rinsing phase in which cold or unheated water is provided to the cleaning device(s) 145. In embodiments including multiple cleaning devices 145, the first / second washing phases and the rinsing phase can be performed in series, in parallel, in alternating order, and / or the like. For example, in some implementations, the washing phases and rinsing phase can be performed for a first cleaning device 145 configured to clean a liquid container and once complete, the washing phases and rinsing phase can be performed for a second cleaning device 145 configured to clean a lid. Alternatively, the washing phases can be performed for both cleaning devices 145 followed by the rinsing phase for both cleaning devices. The rinsing phase is performed after the washing phases to, for example, rinse away any remaining cleaning solution as well as reduce a temperature of the liquid container and / or components thereof caused by the washing phases. Although not shown in FIG. 1, the cleaning system 100 can also include a blower or the like configured to provide a flow of air into the cleaning chamber 120 which can facilitate and / or enhance a drying and / or cooling of the liquid container and / or components thereof after a completed cleaning cycle.323852021 18Agent’s File Ref. NMCL-001 / 01WO 358969-2003

[0077] Although not shown in FIG. 1, the circulation system 160 can include a flow control valve or other flow control device configured to at least partially control a flow rate and / or pressure of the fluid circulating in the circulation system 160. For example, in some implementations, it may be desirable for the circulation system 160 to provide a flow of fluid (e.g., cleaning solution, water, etc.) to the cleaning device(s) 145 at a flow rate of about 0.3 gpm. In other implementations, it may be desirable to provide the flow of fluid at a lower flow rate or a higher flow rate. In some embodiments, the flow rate of the flow of fluid provided to the cleaning device(s) 145 can be varied depending on the phase of the cleaning cycle, the type of cycle being performed, and / or the like. For example, it may be desirable to provide a flow of fluid at a higher flow rate during a washing phase of a cleaning cycle and at a lower flow rate during a rinsing phase. Similarly, it may be desirable to provide a flow of fluid at a higher flow rate during a self-cleaning cycle than the flow rate during the bottle cleaning cycle.

[0078] The cleaning system 100 includes a controller 180 (also referred to herein as an “electronics system”). In general, the controller 180 can be and / or can include a compute device(s) and / or any other suitable device(s) configured to execute processes (and / or in communication with one or more devices configured to execute processes) associated with controlling any of the components, devices, systems, etc. of the cleaning system 100. For example, the controller 180 (e.g., compute device and / or portion(s) thereof) can form and / or can function as one or more local or remote controllers, that enables and / or allows user control, pre-programmed control, at least semi-autonomous or predictive control, and / or any other type of control of any number of components, machines, devices, and / or any other controllable device(s). Examples of controllers and / or the like can include but are not limited to programmable logic devices (PLD), programmable logic controllers (PLC), a single-board computer (e.g., a Raspberry Pi™, Arduino, etc.), and / or the like. Such controllers can be hardware-based and / or software-based devices configured to receive, process, define, store, and / or send data, signals, instructions, etc. to or from one or more sensors, actuators, encoders, valves, pumps, motors, heaters, power supplies, and / or any other devices. In some instances, the data, signals, instructions, etc. can be and / or can include but are not limited to feedback data; data associated with the operating state, parameters, properties, characteristics, etc. of one or more systems, devices, and / or components; historical data and / or profile data including instructions, processes, and / or information associated with operating under a given set of circumstances and / or parameters; statistical data associated with the control and / or operation of one or more systems, devices, and / or components; data associated with a future operating323852021 19Agent’s File Ref. NMCL-001 / 01WG 358969-2003 state and / or instructions, signals, electrical power, etc. configured to transition the one or more systems, devices, and / or components from a current operating state to the future operating state (e.g., a new or updated operating state); and or the like.

[0079] The controller 180 can be configured to receive electric power from a power source such as, for example, a standard electrical outlet (“Wall Outlet”) supplying a 120 volt alternating current. The controller 180 is further configured to receive one or more inputs such as signals or data from one or more switches, sensors, etc., user input via a user interface or remote control device, and / or any other suitable input. Based on the inputs received, the controller 180 can be configured to execute one or more processes associated with controlling the components of the cleaning system 100. For example, the controller 180 can be configured to distribute AC electrical power to one or more buses, power supply units, relays, transformers, devices, components, etc., which in turn, can cause the cleaning system 100 to perform one or more cleaning cycles or other processes associated with operating the cleaning system 100.[0080 j Although not shown in FIG. 1, the cleaning system 100 can include a user interface that allows a user to interact with the cleaning system 100. The user interface can include any suitable inputs and / or outputs such as, for example, push buttons, indicator lights, and / or the like. In some embodiments, the user interface can include a display or screen such as a touchscreen. The user can provide inputs into the controller 180 and the controller can provide outputs to the user via the screen. As such, after inserting a liquid container into the cleaning chamber 120 and closing the door, the user can provide an input (via the user interface), operable to cause the controller 180 to execute processes associated with performing a cleaning cycle. Once complete, the controller 180 can provide an output (via the user interface) that includes an indication that a cleaning cycle is complete and can unlock the door, thereby allowing the user to remove his or her clean liquid container. On the other hand, if the cleaning system 100 encounters an error during a cleaning cycle, the controller 180, in response to data from a sensor, switch, component, device, etc., can execute processes associated with pausing a cleaning cycle and can provide an output (via the user interface) that includes an indication that an error has occurred. Such errors can include, for example, running out of cleaning solution, a clogged drain, a low-flow or low-pressure condition, a low-power condition, a faulty component such as a valve, pump, heater, etc., and / or the like.

[0081] Referring to FIGS. 2-40, a cleaning system 200 is shown according to an embodiment. The cleaning system 200 can be, for example, an automated cleaning system for323852021 20Agent’s File Ref. NMCL-001 / 01WG 358969-2003 cleaning liquid containers such as reusable bottles (e.g., water bottles). The cleaning system 200 can be designed for implementation in public spaces. For example, the cleaning system 200 can be deployed in public areas like schools, gyms, airports, etc. In some implementations, the cleaning system 200 can be used alongside water bottle fdling stations and can utilize existing plumbing infrastructure to clean reusable containers such as water bottles. In some embodiments, the cleaning system 200 can provide a high-pressure cleaning system with temperature-controlled washing cycles and rinsing cycles that use minimal water while ensuring comprehensive cleaning. In some implementations, the cleaning system 200 can autonomously (or at least semi-autonomously) clean a variety of liquid containers - including lids, caps, straws, etc. thereof - in an efficient manner and in a time that is significantly less than, for example, a commercial dishwashing appliance.

[0082] The cleaning system 200 can include a housing 201, a first holder 230, a second holder 240, a first cleaning device 245, a second cleaning device 255, a fluid circulation system 260, and a controller 280. In some embodiments, the cleaning system 200 can be similar to or substantially the same as the cleaning system 100 described above with reference to FIG. 1. Accordingly, such similar portions, features, aspects, etc. are not described in further detail herein.Housing[0083| The housing 201 of the water bottle cleaner provides the structural framework for the internal components and is divided into two main sections: a lower section 202 (FIGS. 2- 14), which includes structural elements and / or components below a drain plate of the housing 201, and an upper section 215 (FIGS. 18-23), which includes structural elements and / or components above the drain plate. Except where noted otherwise, the housing components can be constructed from stainless steel, galvanized steel, aluminum, or another non-corrosive metal to prevent rust from appearing (or any other suitable material including non-metal materials). The housing 201 is configured to mount the system 200 to a wall, with the lower section 202 and the upper section 215 attached to the wall using separate wall cleats, a mounting method akin to that used for water bottle filling stations. In other embodiments, any suitable method for mounting or attaching the system 200 to the wall may be used.[0084J The lower section 202 of the housing 201 (FIG. 3) consists of various components (e.g., sheet metal parts). For example, the lower section 202 includes a lower front plate 203 (FIG. 2), a lower back plate 204 (FIGS. 3 and 4), a wall cleat 205 (FIGS. 3 and 5), a bottom323852021 21Agent’s File Ref. NMCL-001 / 01WG 358969-2003 support 206 for an expansion tank (FIGS. 3 and 6), a top support 207 for the expansion tank (FIGS. 3 and 7), a bottom plate 208 (FIGS. 3 and 8, front support components 209, 210 (e.g., left and right support components) (FIGS. 3, 9, and 10), side support components 211, 212 (e.g., left and right support components) (FIGS. 3, 11, and 12), a middle bridge 213 (FIGS. 3 and 13), and a semi-circle platform 214 (FIGS. 3 and 14). These components may be made from galvanized steel, stainless steel, aluminum, or a similar non-corrosive metal (or any other suitable material). The lower section 202 and / or the components thereof are configured to support and / or organize components of a fluid circulation system 260 and a controller 280, as described in further detail herein. f 0085 The lower back plate 204 (FIG. 4) is configured to be coupled to the wall cleat 205 (FIG. 5). For example, the lower back plate 204 can define holes or openings configured to receive tabs of the wall cleat 205. The lower back plate 204 can include and / or define any number of additional features, cutouts, openings, etc. for interfacing with a wall electrical outlet, water pipes, and / or any other suitable components (e.g., flanges along its edges to enhance rigidity, other support members, and / or the like). The lower back plate 204 can also provide structure for attaching to and / or supporting any suitable components of the fluid circulation system 260. For example, the lower back plate 204, the bottom support 206, and the top support 207 can collectively provide structural components for attaching to and / or supporting an expansion tank or any other suitable component of the fluid circulation system 260 (e.g., via screws, bolts, fasteners, and / or the like). As shown in FIG. 6, the bottom support 206 can be a flanged platform with a circular hole for receiving a base of the expansion tank. The bottom support 206 attaches to both the lower back plate 204 and the left front support 209. As shown in FIG. 7, the top support 207 is or forms a U-shaped component that is configured to straddle the top of the expansion tank. In some embodiments, the top support 207 can be secured to the lower back plate 204 (e.g., only the lower back plate 204). In some embodiments, the top support 207 includes features, holes, and / or portions for attaching a securing plate or fastener for the top of the expansion tank.

[0086] The bottom plate 208 is attached to the lower back plate 204 and the two front supports 209, 210. The bottom plate 208 (FIG. 8) includes, for example, upward-bent rectangles that can serve as guides for the location of a cleaning solution tank, reservoir, heater, and / or any other suitable component of the fluid circulation system 260. In some embodiments, one guide features a cutout with mounting holes for attaching a cleaning solution level sensor. If, for example, there is no cleaning solution in the tank, the system 200 can be configured to323852021 22Agent’s File Ref. NMCL-001 / 01WG 358969-2003 not prevent the start of any more cleaning cycles and an indicator light can be illuminated to alert maintenance staff to refdl the cleaning solution.

[0087] The front supports 209, 210 (FIGS. 3, 9, and 10), (e.g., one on each side ofthe lower section 202 of the housing 201), are connected at the bottom to the bottom plate 208 (FIG. 8) and at the top to the side supports 211, 212 (FIGS. 9 and 10, respectively) and semi-circle platform (FIG. 11). Each front support 209, 210 has two sections. An upper section can include and / or define bolt holes, flanges, and / or any other suitable feature to facilitate attachment, to add stiffness, to provide mounting locations for other components, and / orthe like. For example, the holes, flanges, etc. can be parallel to the wall and connected to the corresponding side support, and a lower angled section to connect the side supports 209, 210 and bottom plate 208. The angle formed by these two sections can be any suitable angle. In some embodiments, for example, the angle can be about 180 degrees, thought other angles are possible. The angle can be selected to allow the side supports 211, 212 to connect to the bottom plate 208, as the side supports 211, 212 extend farther from the wall than the bottom plate 208 does. The left front support 209 is wider at the bottom with holes for mounting a bottom portion of the bottom support 206. The right front support 210 has additional holes for attaching to features of, for example, a drain drawer or other suitable component. The front supports 209, 210 are configured to be coupled or mounted to the lower front plate 203 (FIG. 2). In some embodiments, the lower front plate 203 can be a panel that is bent into a C-shape to form, for example, the lower front plate and two side plates (e.g., an integrated or monolithic plate, panel, skirt, sheet, etc.).[0088J The two side supports 211, 212 (FIGS. 3, 11, and 12) connect to the front supports 209, 210 (one on either front support), the lower back plate 204 (FIGS . 3 and 4), and the middle bridge 213 (FIGS. 3 and 13). The side supports 211, 212 can include, for example, flanges or other features for stiffness and tabs that connect the side supports 211, 212 to the middle bridge 213. The left side support 211 (FIGS. 3 and 11) can accommodate, receive, and / or couple to a pump 261 ofthe fluid circulation system 260 (e.g., via a tab or other suitable feature configured to facilitate or allow for mounting). The right side support 212 (FIGS. 3 and 12) can hold, support, couple, etc. the drain and / or drain drawer. For example, the right side support 212 can include and / or form a U-shaped support, mounting holes, and / or any other suitable feature. In some embodiments, additional supports can be added to the right side support 212 (and / or the left side support 211) to prevent undesired bending or the like.323852021 23Agent’s File Ref. NMCL-001 / 01WG 358969-2003

[0089] The middle bridge 213 (FIGS. 3 and 13) connects to the left side support 211 and the right side supports 212. The middle bridge 213 can include and / or can form flanges or any other suitable features on one or both sides to increase stiffness of the middle bridge 213. In some embodiments, any number of holes, features, supports, couplers, etc. can be added anywhere along the length of the middle bridge 213 to facilitate or allow for the mounting of plumbing components, controller components, and / or any other suitable components of the cleaning system 200.[0090| The semi-circular plate 214 (FIGS. 3 and 14) is configured to connect or mount to the front supports 209, 210. For example, the semi-circular plate 214 can include and / or form features, mounting holes, couplers, etc. to facilitate and / or allow for the mounting of plumbing components such as, for example, solenoid valves, and / or the like).

[0091] FIGS. 15-23 show the upper section 215 of the housing 201 or one or more components thereof. As described above, the upper section 215 consists of the components situated above (and including) the drain plate 221, as shown in FIG. 15. For example, the upper section 215 includes an upper back plate 216 (FIGS. 15 and 16) that can be mounted to the wall via a wall cleat (e.g., similar to or substantially the same as the wall cleat 205 shown in FIG. 5). For example, the upper back plate 216 can include and / or define holes (e.g., rectangular holes or openings) to accommodate and / or receive tabs or other portion(s) of the wall cleat. The upper back plate 216 has flanges on three sides to, for example, enhance its stiffness and provide mounting points for a top plate 217, side walls 219 (e.g., FIG. 19), and the drain plate 221.

[0092] A top part of the upper section 215 of the housing 201 consists of the top plate 217 (FIGS. 15 and 17) and an upper door track. The upper door track, which can be similar to the lower door track or different from the lower door track, is secured to the top plate 217 through nuts and bolts (or any other suitable means of fastening like welding or various mating surfaces). The top plate 217 may be fastened to both the upper back plate 216 and the middle plate 218 (FIGS. 15 and 18). In doing so, the upper door track may be aligned with and may engage with one or more wheel assemblies of the door, as described in further detail herein.[0093 J The middle plate 218 (FIGS. 15 and 18) is positioned vertically within the upper section 215 of the housing 201 and supports both parts of the bottle interface (e.g., the first holder 230 (bottle holder) and the second holder 240 (lid holder)). The middle plate 218 can define a rectangular cutout configured to receive a portion of the first holder 230 (FIG. 18),323852021 24Agent’s File Ref. NMCL-001 / 01WG 358969-2003 which is mounted on a rear surface or side of the middle plate 218 and extends through the cutout to a user-facing side of the middle plate 218. The second holder 240 or lid holder (FIG. 19) is mounted on the user-facing side of the middle plate 218. For example, the middle plate 218 can include one or more flanges or mounting features at a top and a bottom of the middle plate 218 to facilitate attachment to the top plate 217 and the drain plate 221, respectively. The middle plate 218 can be secured by screws, nuts, sealant tape, and / or any other suitable means of fastening / coupling. Additional supports can be added to the middle plate 218 to provide increased stiffness.|0094| The drain plate 221, which can be attached to the upper back plate 216 by diagonal brackets and / or any other suitable attachment (not shown), includes various holes for plumbing, including those for mounting cleaning devices (e.g., nozzle assembly), water supply, drainage, etc. Metal standoffs may be welded to the drain plate support included in the lower section 202 of the housing 205 (e.g., a lower door track). After water enters the cleaning chamber 220, it flows onto the drain plate 221. The drain plate 221 can have a downward slope that allows or facilitates a flow of wastewater (e.g., via gravity), including any cleaning solution and / or cleaning residues from the bottle or lid, towards a set of drainage holes 222 located on the side of the drain plate 221. The drain plate 221 can be fabricated from any suitable material such as stainless steel, aluminum, etc., to provide a clean aesthetic and ensure efficient water runoff without pooling or substantially without pooling.[0095| The drain plate 221 can also serve as a structural component of the cleaning chamber 220. For example, the edges of the drain plate 221 can be welded to the structure(s) of the upper section 215 of the housing 201, which can form a liquid tight seal that prevents water from leaking into the lower section 202 of the housing 201 (e.g., where components of the fluid circulation system 260 and / or controller 280 are located). Additionally, the drain plate 221 can be connected to the middle plate 218, which supports the bottle interface system (holders 230, 240), to form a liquid tight seal at the connection points (e.g., connected via fasteners, screws, sealant tape or other sealant material, welding, etc.).[0096 | As shown in FIGS. 19 and 20, the upper section 215 of the housing 202 includes a drain assembly 223. The drain assembly 223 can be removably coupled to the upper section 215 to allow access to, for example, a filter 224 (e.g., a mesh filter or drain). As shown in FIG. 20, the drain assembly 223 can be and / or can include a drain drawer that houses, holds, or integrates the filter 224. The drain drawer is removably coupled to the upper section 215 and can be easily slid in and out of the housing 202 (e.g., via a set of wheels, a track, and / or any323852021 25Agent’s File Ref. NMCL-001 / 01WG 358969-2003 other suitable feature). This design facilitates and / or allows for regular cleaning and maintenance, preventing debris buildup and potential blockages in the drain (e.g., the fdter 224), thereby limiting time when the system 200 is not operational.[0097} In use, as the waste liquid (e.g., water, cleaning solution, etc.) exits the cleaning chamber 220 via the drainage holes 222 of the drain plate 221, it passes through the fdter 224, which is designed to capture larger debris before the flow of waste liquid continues through the drainage system. The remaining waste liquid can flow through a standard P-trap, followed by any suitable piping or the like that directs the flow of waste liquid into the building's drainage system.Door

[0098] FIGS. 21-23 illustrate portions of the door assembly 225 of the cleaning chamber 220. The door assembly 225 is designed for both functionality and to maintain a clean, aesthetic appearance. The door assembly 225 can include or incorporate a rotating mechanism with a cutout that allows users to access the interior of the cleaning chamber 220. The arrangement can allow the door assembly 225 to remain contained within the housing 202 rather than extending outward into a hallway or other external space where the system 200 may be implemented and / or deployed.

[0099] The door assembly 225 includes cylindrical, clear acrylic door 226 (FIG. 21), which allows users to visually monitor the cleaning process - contributing to a clean and modem aesthetic, while building trust in the cleaning capability of the system 200. The door 226 features a cutout on one side, positioned to face the user when it is in the open position and serves as an access into the interior of the cleaning chamber 220 for placing or removing the bottle and lid. When the door 226 is closed, this cutout is inaccessible, preventing user interaction with the interior of the cleaning chamber 220 (e.g., during a cleaning operation). In some embodiments, the door 226 can include or can be coupled to a handle (e.g., attached to the right side of the cutout), facilitating easy opening and closing of the door 226.

[0100] The door assembly 225 further includes lower track 227A and an upper track 227B (FIG. 21). The tracks 1K, TQ can be rings attached to or configured to engage the upper edge and lower edge of the door 226, respectively. For example, the tracks 11K, l'Q can be cut from 1 / 4” aluminum sheets or can be formed using any other suitable method or material. The lower track 227A can be mounted onto the angled drain plate 221. To ensure the lower track 227A remains level despite the angled drain plate 221, standoffs of varying heights can323852021 26Agent’s File Ref. NMCL-001 / 01WG 358969-2003 be used (e.g., coupled, welded, etc. to the inner edge of the drain plate 221. The standoffs (not shown) can be equipped with threaded holes on the top to provide a stable mounting base for the lower track 227A. The lower track 227A can be secured to the standoffs in a manner to ensure a smooth surface so that the door's rolling mechanism is not hindered. The upper track 227B can be attached or mounted to the top plate 217 of the upper section 215 of the housing 202, as described with reference to the lower track 227A. Optionally, standoffs can be used to ensure the upper track 227B is flat or substantially flat.[0101 | The door assembly 225 includes a set of lower track carriages 228 (FIGS. 21 and22) configured to support and guide the door 226 rotating or moving along the lower track 227A. For example, the door assembly 225 can include at least three lower track carriages 228 to ensure stability and smooth operation. Each lower track carriage 228 can include a base 228A, one or more wheels 228B, and amounting feature 228C. The base 228A includes and / or forms a curved slot with a radius and thickness matching that of the door 226, allowing the lower track carriage 228 to slide onto the door 226. The mounting feature 228C is configured to secure the wheel(s) 228B to the base 228A. In some embodiments, the base 228A and the wheel(s) 228B can be formed from polymer material(s) such as thermoplastics and / or the like, while the mounting feature 228 C can be formed from a metal such as aluminum. In other embodiments, the components of the lower track carriages 228 can be formed from any other suitable material or combination(s) of materials.[0I02| The door assembly 225 includes a set of upper track carriages 229 (FIGS. 21 and23) configured to support and guide the door 226 rotating or moving along the upper track 227B. In some embodiments, the upper track carriages 229 can be configured to provide suspension for the door 226. The door assembly 225 can include at least three upper track carriages 229 to ensure stability and smooth operation. Each upper track carriage 229 includes a base 229A, a set of wheels 229B, a mounting feature 229C, a door clip 229D, and a suspension member 229E. The upper track carriages 229 can be similar to the lower track carriages 228. For example, the base 229A is a curved component with a radius that substantially matches that of the door 226. The mounting feature 229C is configured to secure the wheel(s) 229B to the base 229A. In some embodiments, the base 229A and the wheel(s) 229B can be formed from polymer material(s) such as thermoplastics and / or the like, while the mounting feature 229C can be formed from a metal such as aluminum. Each upper track carriage 229 includes a door clip 229D. The door clip 229D can include and / or form a curved slot for receiving and / or sliding onto the door 226. The suspension member 229E is configured323852021 27Agent’s File Ref. NMCL-001 / 01WG 358969-2003 to couple the door clip 229D to the base 229A. The suspension member 229E can be, for example, a flat spring, that provides an attachment point between the base 229A and the door clip 229D, thereby forming a suspension mechanism that allows for slight relative movement (e.g., vertical movement) between the base 229A and the door clip 229D that can absorb inconsistencies associated with the rotation or movement of the door 226.[01031 Although not shown, the door assembly 225 includes or is configured to engage a switch or sensor that can detect a state or position of the door assembly 225. For example, such a switch or sensor can detect whether the door 226 is in an open or closed state and can communicate a signal associated with the state to the controller 280. The door assembly 225 can also include a latching mechanism (e.g., a magnetic door latch) configured to keep the door shut in the closed position or state until a door lock is engaged. In some instances, the latching mechanism can provide the user with feedback that the door 226 is shut as they can feel the magnet holding the door 226 in place. Such a magnetic latch can include two components: a magnet mounted on the door 226 and a base mounted on the upper section 215 of the housing 201 (or vice versa). When the door 226 is closed, the magnet makes contact with the base and maintains the door 226 in a shut or closed state due to the magnetic interactions. Once the door 226 is closed, a solenoid or any other actuator can be used to engage, lock, and / or secure the door 226 in the closed position or state, preventing access to the interior of the cleaning chamber 220 during the cleaning cycle. This solenoid, actuator, lock, etc. can be disengaged automatically when the wash cycle ends, allowing the user to open the door and retrieve the bottle and lid.[0104| While the door assembly 225 is described above with reference to FIGS. 21-23, it should be understood that other configurations are possible - e.g., using different manufacturing methods, materials, attachment mechanisms, wheels, etc. Variations on the door assembly include different wheel geometries, different wheel materials, other methods of spring loading the door to stay on the track, sensors for detecting if the door is closed, different door latches and / or door locking mechanisms, and / or the like.Bottle Interface[0105J FIGS. 24-27 illustrate a bottle interface of the cleaning system 200. More specifically, the bottle interface includes a bottle holder 230 and a lid holder 240, each of which are disposed in the cleaning chamber 220 of the system 200 (as shown in FIG. 27). The bottle holder 230 and the lid holder 240 are configured to suspend the bottle and lid, respectively,323852021 28Agent’s File Ref. NMCL-001 / 01WO 358969-2003 above two different cleaning devices while minimizing contact to reduce cross contamination of debris between users.

[0106] As shown in FIGS. 24 and 25, the bottle holder 230 is and / or includes a spring- loaded mechanism configured to center a bottle securely over the corresponding cleaning device. The bottle holder 230 is configured to accommodate a wide range of commercial bottle sizes and is designed to receive and hold the bottle with little force exerted from the user to insert and remove the bottle. The bottle holder 230 includes a set of arms 231 that make contact with a surface of the bottle. The arms 231 are mounted on a track 232 that allows the arms 231 to linearly move outwards and inwards. The arms 231 are configured with outward-bending ends to guide the bottle into a desired position and a curved center to ensure vertical centering over the cleaning device 245. The arms 231 are mounted onto the track 232 using a rod 233 and rollers 234 to allow linear movement. A spring 235 is placed around the rod 233 and provides the inward force that causes the arms 231 to clamp or hold the bottle.

[0107] The arms 231 can be formed using any suitable material or combination of materials. For example, the arms 231 can be formed from two different materials. A main structure of the arms 231 can be made of a corrosion-resistant metal, such as aluminum, and an inside portion of the arms 231 can be lined with a high-friction foam material, such as PORON, though other high-friction foams may be used. The high-friction foam or other material can facilitate the gripping of the bottle. In contrast, the rods 233 can be formed from a low-friction material, such as a thermoplastic (e.g., Delrin or the like). Other materials and / or configurations of the bottle holder 230 are possible. In any configuration, the bottle holder 230 can be configured to facilitate the smooth insertion and removal of the bottle, accommodate bottles having various sizes, and automatically center or align the bottle (independent of the bottle size) relative to the cleaning device 245, while preventing or limiting scratching or damaging the bottle.

[0108] FIG. 26 shows the lid holder 240. The lid holder 240 is designed to secure the lid above a corresponding cleaning device 255. In this embodiment, the lid holder 240 can be a wire basket or the like that is made to accommodate various lid sizes while minimizing contact area. Although not shown, the lid holder 240 can include, for example, a hinged top configured to retain the lid in the basket. Other configurations of the lid holder 240 are possible. For example, a lid holder can be a silicone or rubber funnel with horizontal ridges around its circumference. The funnel’s open front allows for the insertion and removal of lids of various diameters between the ridges.323852021 29Agent’s File Ref. NMCU-001 / 01WG 358969-2003

[0109] As shown in FIG. 27, the bottle holder 230 and the lid holder 240 are mounted to the middle plate 218 that sits in the center of the upper section 215 of the housing 201. Moreover, the bottle holder 230 and the lid holder 240 are disposed in the cleaning chamber in positions that are substantially aligned with the cleaning devices 245, 246, respectively.Fluid Circulation System[OHO] The fluid circulation system 260 of the cleaning system 200 is designed for providing high-pressure hot and cold water for the purpose of cleaning bottles and lids in an efficient and effective manner. FIG. 28, for example, outlines the different states of the fluid circulation system 260. In some embodiments, water is drawn directly from a standard wall connection and enters the fluid circulation system 260, with an anticipated pressure range of 20 to 80 psi and a flow rate between 1 to 2 gallons per minute (gpm), consistent with standard water supply conditions in U.S. buildings. The states can include, for example, a water heating phase, a bottle: hot, soapy wash phase, a bottle: hot wash phase, a bottle: cold rinse phase, a lid: hot, soapy wash phase, a lid: hot wash phase, and a lid: cold rinse phase. While described as providing a hot, soapy wash phase for both the bottle and the lid, it should be understood the cleaning system 200 can use soap or any other non-soap cleaning solution (e.g., the term “soap” is used for ease of understanding). Moreover, while the various states are listed as sequentially passing through various phases, any of the phases or states can be performed in parallel. For example, any or all of the bottle phases can be performed in parallel with any or all of the lid phases.[01111 FIG. 29 is a schematic representation of the fluid circulation system 260. Upon entry into the fluid circulation system 260, a flow of water can be divided by a tee fitting 264 into a hot water pathway and a cold water pathway. Water flow through the circulation system 260 is controlled by solenoid valves, which are electromechanically controlled valves that can be set as either open or closed. During the heating phase, for example, a solenoid valve 262A on the hot water path is open, while a solenoid valve on the cold water path 262B is closed, allowing water to flow solely through the hot water pathway.

[0112] Once a flow of water enters the hot water path, a flow control valve 263 can reduce, adjust, and / or set a desired flow rate (e.g., around 0.3 gpm) of the water through the hot water path. In some embodiments, flow rate can be based at least in part on a minimum flow rate of or associated with the heater 270 (e.g., an electric tankless heater, an inline heater, a heated water tank, and / or any other suitable heat source. For example, the heater 270 can be an electric323852021 30Agent’s File Ref. NMCL-001 / 01WG 358969-2003 tankless heater, which uses resistive heating technology. Reducing the flow rate through the heater 270 can be desirable to increase the time the water spends in the heater 270, thereby increasing the exit temperature of the hot water. In some embodiments, when the heater 270 is connected to a standard U.S. electrical outlet (120 volts (V), 20 amps (A)), the heater 270 can have a maximum power output of 1800 to 2400 watts. In other embodiments, the size, configuration, power, etc. of the heater 270 can be based at least in part on the size of the system, a desired temperature range of the water exiting the heater 270, and / or any other suitable factor.

[0113] During the water heating process, a solenoid valve 262E situated between the electric heater and thermal expansion tank 272 (also referred to as an accumulator) remains open, allowing hot water exiting the electric heater to flow into the thermal expansion tank 272. The heated water is stored in the thermal expansion tank 272 at the temperature reached upon exiting the electric heater and the exit pressure, which is close to the input pressure of the water from the wall. The thermal expansion tank 272 can be insulated with typical insulation materials to keep the water hot when the system 200 is not being used. In some embodiments, the thermal expansion tank 272 can have any suitable capacity, which can be based at least in part on an amount of water used during a wash cycle or a number of wash cycles (e.g., one gallon, two gallons, or more). A solenoid valve 262D located after the thermal expansion tank 272 remains closed during the heating and storage phase to prevent the movement of heated water further into the circulation system 260.[011 1 This water heating system is specifically designed to provide instant or substantially instant high-pressure, hot water, allowing the cleaning system 200 to wash multiple bottles in succession with limited wait time for water heating between cycles. The water entering the thermal expansion tank 272 can be uniformly heated to a consistent temperature. In contrast, conventional tanked water heaters typically receive a larger volume of cold water, which goes through an extended period of heating since all the water in the tank is being heated at the same time. Such a conventional system may result in insufficiently heated water or may result in longer wait times for the heating cycle between washes.

[0115] FIG. 30 illustrates at least a portion of the fluid circulation system 260 that is schematically shown in FIG. 29. After the thermal expansion tank 272 is filled for a predetermined period of time (e.g., determined at least in part by factors including flow rate and water left in the tank), the solenoid valve 262E between the heater 270 and the thermal expansion tank 272 closes, stopping the flow of additional water into the hot water pathway.323852021 31Agent’s File Ref. NMCL-001 / 01WO 358969-2003When the wash cycle is initiated by the user, the solenoid valve 262D downstream of the thermal expansion tank 272 opens, allowing the stored hot water to flow towards the cleaning devices 245 and 255 at a significantly higher flow rate than the reduced flow rate used during the heating phase. In the heating phase, the flow control valve 263 can be actuated to restrict or limit flow to increase the exit temperature of water from the heater 270. When the thermal expansion tank 272 opens, however, there is no similar flow control valve, thus the water will flow at the higher flow rate to wash the bottle and lid.[0116| For the initial few seconds of the wash cycle, a cleaning solution (e.g., a liquid soap, dishwasher detergent, and / or any suitable cleaning agent) is introduced into the hot water stream. This is accomplished using, for example, a peristaltic pump 261 that injects cleaning solution from cleaning solution tank 265 into the water stream. The peristaltic pump 261 works by using a rotor to displace liquid through flexible tubing, pumping it forward. Other pump variations can be used to achieve the same outcome. More concentrated clean solution mixtures or a larger cleaning solution tank 265 can be used to increase the time between required maintenance cycles. Maintenance staff can open the side of the cleaning system 200 by unscrewing and removing the outer housing side panel (FIG. 10) to access and refdl the cleaning solution tank 265 when empty. In some embodiments, the cleaning system 200 can include a sensor or the like to detect an amount of cleaning solution in the cleaning solution tank 265. Alternatively, the cleaning system 200 can include a level light that illuminates at least a portion of the surface of the cleaning solution, allowing maintenance staff to assess the fdl level.[0H7| When the peristaltic pump 261 begins to inject the cleaning solution into the flow of water, the solenoid valve 262B at the first cleaning device, designated for cleaning the bottle, opens to allow the hot cleaning solution / mixture to enter the first cleaning device. The hot cleaning solution / mixture continues to flow after the injection of the cleaning solution stops. Then, the solenoid valve 262D following the thermal expansion tank 272 can close, stopping the hot water flow.[0U8| After a washing process, the solenoid valve 262A on the cold water pathway can open, allowing cold water to flow (e.g., directly from the wall supply) to the first cleaning device to rinse the bottle. Following the bottle rinse, the solenoid valve 262B for the first cleaning device can be closed. In some instances, once the bottle has been washed and rinsed, the solenoid valve 262C for the second cleaning device (e.g., the lid nozzle) opens. The same323852021 32Agent’s File Ref. NMCL-001 / 01WG 358969-2003 cleaning process may then be applied to the lid, beginning with a hot wash with the cleaning solution / mixture, followed by a hot water wash, and concluding with a cold water rinse.

[0119] The solenoid valves described above 262A-262E can be electronically controlled using a programmable logic controller (PLC), which may be integrated into or executed by the controller 280. Throughout the circulation system 260, braided stainless steel pipes and connectors ('A” or3 / s”, depending on the component) can be utilized to ensure flexibility, minimize the length of piping, reduce the risk of kinks or sharp comers / bends that could cause pressure losses, etc. The fittings, tees, connectors, etc. are selected to be suitable for potable water.

[0120] Nonlimiting features associated with the circulation system 260 can include dual hot and cold water pathways, distinct flow rates (e.g., a low-flow rate during the heating stage and a high-flow rate during the cleaning stage), separation of cleaning devices for bottles and lids, selective and / or controlled injection of a cleaning solution into a flow of water, and / or the like. Variations of the present fluid circulation system may include different types or configurations of the valves or alternative materials for the pipes and connectors, provided they maintain the integrity of the circulation system’s performance.Cleaning Devices

[0121] As shown in FIGS. 31-36, the cleaning system 200 includes two distinct cleaning devices designed to optimize the cleaning of the bottle and the lid. The first cleaning device 245 (also referred to as a “first nozzle” or “bottle nozzle”) is configured to clean the bottle and the second cleaning device 255 (also referred to as “second nozzle” or “lid nozzle”) is configured to clean the lid. The cleaning devices 245, 255 can be configured to target areas that are typically the dirtiest, such as the threads where the lid and bottle typically join and the opening where the user drinks from. Each cleaning device 245, 255 can be uniquely designed to clean either the bottle or the lid.

[0122] FIGS. 31-34 show the first cleaning device 245 (e.g., the bottle nozzle). The bottle nozzle 245 includes several components, including a top piece 246, a middle piece 247, a bottom piece 248, a bearing 249, and a nut 250. The components can be coupled together via fasteners, adhesives, ultrasonic welding, etc. The first cleaning device 245 further defines a flow channel 251 that extends through the first cleaning device 245 and that receives a flow of the cleaning solution / mixture, water, and / or any other suitable fluid). As such, the first cleaning device 245 is configured to receive a flow of fluid from the circulation system 260 and to direct323852021 33Agent’s File Ref. NMCL-001 / 01WG 358969-2003 the flow of fluid toward a bottle secured by the bottle holder 230. In addition, at least a portion of the first cleaning device 245 (e.g., the top piece 246) can be configured to spin or rotate during a cleaning operation, as described in further detail herein.[0123} As shown in FIGS. 32 and 33, the top piece 246 of the first cleaning device 245 (bottle nozzle) includes and / or forms a set of arms. In this embodiment, for example, the top piece 246 includes two arms. The arms extend outward and include holes or ports to allow fluid flow therethrough. For example, in some embodiments, the arms can define six holes. In other embodiments, each arm can define fewer than six holes or more than six holes. Moreover, each arm can include a different number of holes (e.g., an asymmetric configuration). The holes can be positioned to direct a flow of fluid toward a bottle held or secured by the bottle holder 230 allowing the first cleaning device 245 to clean various bottle opening sizes and target both internal and external threads on the bottle. The holes can be set at a predetermined or desired angle to ensure effective cleaning by directing water at the threads and preventing excessive water from hitting the outside of the bottle (e.g., the non-threaded portion or the portion that a user does not drink from). In some embodiments, the holes can be angled in a direction away from a direction of rotation of the first cleaning device 245. Such an arrangement can facilitate or at least partially cause rotation of the top piece 246 due to the momentum of the water, thereby enabling dynamic cleaning action without additional actuation. The top piece 246 can also define one or more central hole or opening that allows a higher volume of water to enter and clean the inside surfaces of the bottle (FIGS. 32 and 33). In embodiments including multiple central holes, the central holes can be angled such that water hits the side surfaces inside the bottle. The angled exit of water through central holes would also further facilitate rotation of the top piece 246. Further variations of the top piece 246 may include, for example, a different number of arms and / or exit holes, different angles for the arms and / or exit holes, different materials, the inclusion of brushes or other cleaning surfaces configured to contact portions of a bottle, and / or the like.

[0324] The middle piece 247 is configured to couple (e.g., at least indirectly) to the top piece 246. The middle piece 247 defines an inner surface that accepts the bearing 249 (positioned between the middle piece 247 and the top piece 246) and the nut 250 (positioned between the middle piece 247 and the bottom piece 248). As shown in FIG. 33, the bearing 249 may be pressed into an inner portion of the middle piece 247 and a portion of the top piece 246 may be pressed into an inner portion of the bearing 249. Thus, the bearing 249 can couple the top and middle pieces and allow for smooth rotation of the top piece 246 relative to the middle323852021 34Agent’s File Ref. NMCL-001 / 01WG 358969-2003 piece 247, enhancing the coverage achieved by the cleaning process by adding rotational movement. The bearing 249 can be constructed from a rust-proof, potable-water-safe metal, plastic, or glass to ensure durability and safety in a water-cleaning environment.[0125} The bottom piece 248 is configured to couple to the middle piece 247. For example, the bottom piece 248 can be fastened or coupled to the middle piece 247 using screws, bolts, an adhesive, ultrasonic or chemical welding, and / or the like. The bottom piece 248 is coupled to the middle piece 247 to secure the nut 250 therebetween. The assembled bottle nozzle 245 is coupled to a corresponding fitting of the circulation system 260. For example, the nut 250 can be screwed onto a corresponding fitting, thereby integrating the bottle nozzle 245 with the circulation system 260. As shown in FIG. 34, the arrangement of the first cleaning device 245 (bottle nozzle) allows fluid (e.g., a cleaning solution / mixture, water, and / or any other suitable fluid) to be directed to select portions of a bottle that is secured in the bottle holder 230. The select portions include, for example, the interior surface(s) of the bottle, the threaded portion of the bottle (e.g., where the user places his or her lips), and / or any other suitable portion of the bottle. Moreover, the arrangement of the first cleaning device 245 allows for the cleaning of bottles having various shapes, sizes, and configurations.[0126J As shown in FIGS. 35 and 36, the second cleaning device 255 (e.g., lid nozzle) can be stationary component designed to clean the threads on bottle lids, whether they are internal or external. The second cleaning device 255 includes a set of arms 256, which each arm 256 extending from a central hub. The embodiment shown in FIGS. 35 and 36 includes three arms 256, however, more or fewer arms are possible. The arms 256 include and / or define a set of angled ports or exit holes 257. These holes 257 are directed inward to focus a flow of fluid toward or on the lid threads, ensuring thorough cleaning. The second cleaning device 255 is configured to couple to (e.g., screws onto) a corresponding fitting of the circulation system 260. Variations of the second cleaning device 255 may include, for example, different numbers of arms and / or exit holes to accommodate various lid shapes and sizes, different angles of the arms and / or exit holes, and / or the like. Additional variations may include, for example, a cleaning device configured to rotate in a manner that is structurally and / or functionally similar to the first cleaning device 245.[0127J The cleaning devices 245 and / or 255 and / or components thereof can be made using any suitable material and / or method. For example, one method of manufacturing the cleaning devices 245 and 255 can include using 3-D printing technology (e.g., stereolithography (SLA)) with water-soluble supports. This method can allow for intricate details inside the cleaning323852021 35Agent’s File Ref. NMCL-001 / 01WG 358969-2003 devices 245 and / or 255, providing greater control over the water flow paths to optimize cleaning efficiency. Different manufacturing methods and / or materials are also possible.Controller

[0128] FIG. 37 is a schematic diagram of a controller 280 and / or electronic system included in the cleaning system 200. The controller 280 is configured to receive electric power from a power source such as, for example, a standard electrical outlet (“Wall Outlet”) supplying a 120 volt alternating current. The current is distributed via a distribution bus (“AC Distribution Bus”) . The AC distribution bus supplies power to a number of relay outputs of a programmable logic controller (PLC) (“PLC Relay Outputs”) and a power supply unit (“PSU”) that can convert the input 120 volts of alternating current into 120 volts of direct current. The PSU provides energy to the solenoid valves via the PLC Relay Outputs. The PLC Relay Outputs are configured to relay power from the AC Distribution Bus to a set of different outputs. In this embodiment, for example, a first relay output can be connected to a solid state relay (“SS Relay”), which in turn can provide power to a water heater (“Heater”). Five other PLC Relay Outputs are configured to relay power to a set of solenoid valves (e.g., the solenoids 262A, 262B, 262C, 262D, and 262E described above with reference to FIGS. 29 and 30, (“Solenoids”)). The Solenoids are coordinated to control the flow fluid through the circulation system 260 (e.g., cold water, hot water, cleaning solution, etc.), as described above with reference to FIGS. 29 and 30. The Solenoids, the Heater, and the PSU are all connected to, for example, a true earth ground of the wall outlet (“Ground (Earth)”), grounded to earth by connecting to the true earth ground from the electrical wall connection.[0129J The PSU also provides energy to a 12 volt DC distribution bus (“DC Distribution Bus”). The DC Distribution Bus provides DC energy to the programmable logic controller (“PLC”). The PLC includes a set of digital inputs (“PLC Digital Pin Inputs) and a set of analog inputs (“PLC Analog Pin Inputs”), and is connected to and controls the PLC Relay Outputs. In this embodiment, the DC distribution bus also provides DC energy to a set of PLC Relay Outputs and to a step down transformer (“Step Down”). The set of PLC Relay Outputs receiving the DC energy are configured to relay power to a door lock (“Door Lock”) and a cleaning solution pump such as, for example, a peristaltic pump (“Pump”). The Step Down transformer is configured to step down the DC energy to 5 volts and to provide the 5 volt DC energy to a programmable circuit board or microcontroller such as, for example, an Arduino (“Arduino”). The Arduino can be connected to and / or receive signals / data from any number of323852021 36Agent’s File Ref. NMCL-001 / 01WG 358969-2003 sensors or other inputs such as, for example, a drain overflow switch, a cleaning solution level sensor, and / or the like. In some embodiments, the Arduino (or other microcontroller) can be configured to prevent the start of a cleaning cycle or to stop an ongoing cleaning cycle in response to an undesired reading from a switch, sensor, and / or the like. Although not shown in FIG. 37, the controller 280 and / or electronic system can include any number of indicator lights (e.g., cycle state indicator lights and / or the like), which can receive 120 volt AC energy (or 12 volt DC energy). For example, one or more cycle state indicator lights can receive 120 volt AC energy in parallel to the solenoid valves, which can provide improved accuracy in communicating the current state of the cleaning system 200 to the end-user or to maintenance, janitorial, or other staff.User Interface[0130| The term 'user,' as used herein, generally refers to an individual or entity that interacts with, or observes the user interface. The user may be a technician or an end-user of the machine. In some embodiments, the cleaning system 200 can include features intended to enhance the user’s experience. For example, the upper section 215 of the housing of the cleaning system 200 includes a cleaning chamber 220 with a revolving door assembly, a user control panel 282 (FIG. 38), and a side panel 284 (FIG. 40). In some embodiments, the housing of the cleaning system 200 is designed to enhance a user's perception of cleanliness and reliability, and it encourages integration when placed next to a water fountain or fdling station. Materials used to form the housing and / or other components can include, for example, stainless steel, anodized aluminum, and / or the like can ensure durability, corrosion resistance, and ease of sanitization.[01311 FIG. 40 is a non-limiting example of a user interface flowchart. For example, a single button can be provided on the cleaning system 200 associated with starting a cleaning cycle. The button can include an LED encircling it that gives information about the current state of the cleaning system 200. If the cleaning system 200 is not connected to power, the button LED may be off. On the other hand, if the cleaning system 200 is powered and functioning properly, the button LED will be on and white. The cleaning system 200 can perform system checks or can receive signals indicative of the state of one or more components of the system 200. If, for example, the drain assembly is clogged or otherwise not functioning (e.g., the drain drawer is not fully or correctly inserted in the housing), the cleaning solution level sensor indicates the cleaning solution is below a threshold level, and / or any other323852021 37Agent’s File Ref. NMCL-001 / 01WO 358969-2003 undesirable state, the button LED may be illuminated red, and a cleaning cycle cannot be started. If, after system checks, the system 200 is ready, the user can insert their bottle into the bottle holder 230 (FIGS. 24 and 25) and / or their lid into the lid holder 240 (FIG. 26) and close the door 225. The middle wall 218 disposed in the cleaning chamber 220 can include, for example, indicia or the like that can instruct a user on the correct orientation of the bottle and lid (FIG. 27). When the door is fully shut, a door LED will turn green, indicating that the water has heated, the accumulator is full, and the cycle is ready to begin. If the user inserts their bottle and tries to begin the cycle before closing the door, the door LED will blink. Assuming that the programmed cycle conditions are met, if the cycle start button is pressed, door locks and a lock LED may be illuminated. In addition, a cycle LED may change color from green to blue, indicating a successful cycle start. In some embodiments, before or at the beginning of the cycle (e.g., while the accumulator is filling with heated water), an LED may be illuminated to indicate the system 200 is “getting ready.” As the cycle progresses, various LEDs may be illuminated to indicate what phase of the cleaning cycle is being performed. Once the cycle is complete, the lock LED may turn off to indicate that the door is unlocked. The user is then free to open the door and remove their bottle. The side panel (FIG. 39) may include pictorial instructions for the user (e.g., insert, close, press start, wash, and complete), simplifying the operation steps of the cleaning system 200 and making it user-friendly, especially for first-time users.[0! 32| The user interface system and / or aspects or methods associated with interacting with the user interface system are provided above by way of example and not limitation. Variations in the user interface system are possible and will be appreciated by those skilled in the art.[0133J Similarly, variations or other components and / or features of the cleaning system 200 are possible . For example, in some embodiments, a cleaning system may include a payment system. The payment system may accept any suitable form of payment. Once payment is received, the cleaning system can be activated to clean the user’s bottle.{0134| As another example, a cleaning system may include a digital screen in addition to or instead of the user-interface panel to show, for example, how much time is left in the cleaning cycle, what maintenance the machine requires, paid advertisements while the machine is cleaning, and / or any other suitable information. In some embodiments, advertisements may appear in multiple places on the machine, such as on this screen, on panels of the housing, and / or the like.323852021 38Agent’s File Ref. NMCL-001 / 01WO 358969-2003

[0135] As another example, a cleaning system may include any additional cleaning features that can be integrated into the cleaning cycle. Some such additional features can include but are not limited to using UV light to clean the bottle and / or the cleaning chamber, drying the bottle and lid with air (e.g., heated or non-heated air), using steam or ultrasonic waves to facilitate or enhance cleaning, optionally cleaning additional portions of a bottle such as cleaning straws, etc., and / or any other suitable cleaning features.

[0136] As another example, a cleaning system can include any number or type of sensors and / or other methods can be added to the system to track cleaning metrics and measure cleanliness in a bottle to report back to users and those who run the cleaning stations. The system can be altered to have different cleaning cycles (including but not limited to different amounts or types of soap as well as different cycle times) depending on how dirty a user's water bottle is. Further, there is the potential for the system to use cameras in conjunction with machine learning models and artificial intelligence (like Al-enhanced image processing) to determine how dirty a water bottle is and select custom cycle settings (for example, a custom cycle time and amount of soap, among other settings) to clean the water bottle.

[0137] Fifth, a mobile app can be paired with the system for a variety of reasons such as facilitating payment for washes or sending reminders to users that they need to wash their bottles.

[0138] Sixth, other variations of the product can include different physical forms for the product. For example, instead of being wall-mounted, the system can come in a table-top form or can sit on the ground, among other configurations.]0139J Some embodiments described herein relate to and / or otherwise include a computer storage product with a non-transitory computer-readable medium (also can be referred to as a non-transitory processor-readable medium) having instructions or computer code thereon for performing various computer-implemented operations. The computer-readable medium (or processor-readable medium) is non-transitory in the sense that it does not include transitory propagating signals per se (e.g., a propagating electromagnetic wave carrying information on a transmission medium such as space or a cable). The media and computer code (also can be referred to as code) may be those designed and constructed for the specific purpose or purposes. Examples of non-transitory computer-readable media include, but are not limited to, magnetic storage media such as hard disks, floppy disks, and magnetic tape; optical storage media such as Compact Disc / Digital Video Discs (CD / DVDs), Compact Disc-Read Only Memories (CD-323852021 39Agent’s File Ref.
