[0001] DOCKING STATION WITH AUTOMATED FILTER CLEANING SYSTEM

[0002] FOR POOL CLEANING ROBOTS

[0003] RELATED APPLICATION

[0004] This application claims the benefit of priority of US Provisional Patent Application No. 63 / 721,600, filed on November 18, 2024, the contents of which are incorporated herein by reference in their entirety.

[0005] FIELD AND BACKGROUND OF THE INVENTION

[0006] The present invention, in some embodiments thereof, relates to a docking station for automated pool cleaning robots and, more particularly, but not exclusively, to a docking station equipped with an integrated cleaning and maintenance system for autonomous filter cleaning and robot servicing.

[0007] Pool cleaning robots have become increasingly prevalent in residential and commercial pool maintenance applications. These autonomous devices typically operate underwater to collect debris, scrub surfaces, and maintain water clarity through various cleaning mechanisms. Modern pool cleaning robots generally incorporate rechargeable battery systems, onboard filtration units, and navigation systems that enable systematic coverage of pool surfaces.

[0008] Robotic systems across various industries commonly utilize docking stations for power management and maintenance operations. Such docking stations may provide charging capabilities, data transfer interfaces, and automated servicing functions. In the context of pool maintenance equipment, docking stations have been developed to accommodate the specific operational requirements of waterproof devices that transition between aquatic and terrestrial environments, for example when battery powered robots are used (cordless).

[0009] Automated maintenance systems for robotic devices often incorporate sensor technologies, mechanical actuators, and control systems to perform routine servicing operations. These systems may include cleaning mechanisms, component inspection capabilities, and status monitoring functions. Integration of multiple maintenance functions within a single station can provide operational efficiency and reduce manual intervention requirements.

[0010] Filter maintenance represents a common operational requirement for pool cleaning equipment. Various approaches have been developed for cleaning and maintaining filtration components, including manual removal and cleaning, backwash systems, and automated cleaning mechanisms. The effectiveness of filtration systems often depends on regular maintenance to prevent clogging and maintain optimal performance. Contemporary robotic systems increasingly incorporate wireless communication capabilities, sensor networks, and automated decision-making algorithms. These technologies enable remote monitoring, adaptive operation parameters, and integration with broader home automation systems. The convergence of robotics, automation, and communication technologies continues to expand the capabilities of specialized robotic applications.

[0011] SUMMARY OF THE INVENTION

[0012] According to an aspect of some embodiments of the present invention, there is provided a docking station for a pool cleaning robot, the docking station comprising: a charging unit adapted to charge a rechargeable energy source of the pool cleaning robot; a pop-up sprinkler system adapted to emerge from the docking station and clean a filtering unit of the pool cleaning robot; and a container aligned with an opening of the pool cleaning robot when docked, wherein the pop-up sprinkler extends into an interior portion of the robot through the opening to wash the filtering unit.

[0013] According to another aspect of some embodiments of the present invention, there is provided a pool cleaning robot comprising: a robot body defining an opening formed in the robot body and providing access to an interior portion within the robot body; a filtering unit disposed within the interior portion and accessible through the opening; a charging interface positioned on the robot body and configured to receive power from a charging unit of the docking station when the robot is in a docked position; and a propulsion system configured to propel the robot onto the docking station and position the robot such that the opening aligns with a container of the docking station to receive the pop-up sprinkler that emerges and extends into the interior portion to wash the filtering unit when the robot is in the docked position.

[0014] According to further aspects of some embodiments, the docking station may include a camera positioned to monitor the cleaning operation and determine cleaning completion based on water clarity analysis. The pop-up sprinkler may be pressure-activated and include a rotational cleaning head for thorough filter washing. The robot may include a hinged door mechanism that automatically opens and closes during docking operations through mechanical engagement with station components.

[0015] Some embodiments described in the present disclosure relate to a docking station for a pool cleaning robot.

[0016] In some embodiments, a docking station for a pool cleaning robot may be adapted for deployment at a location outside of, a water pool.

[0017] In some embodiments, the docking station may be adapted for charging a rechargeable energy source of the pool cleaning robot when the pool cleaning robot is docked at the docking station. The docking station may comprise a charging socket adapted to engage with a corresponding plug of the pool cleaning robot for electrically connecting the pool cleaning robot and the docking station.

[0018] Additionally or alternatively, the docking station and / or the pool cleaning robot may be adapted for wireless power transfer from the docking station to the rechargeable energy source, e.g., the docking station may comprise an inductive pad and / or the like for inductive charging.

[0019] In some embodiments, the docking station may be adapted for washing the pool cleaning robot and / or portion thereof, for example, cleaning a filtering unit of the pool cleaning robot and / or the like. The docking station may comprise a pop-up sprinkler adapted to selectively and reversibly emerge out of the docking station and enter via an opening at a body or encasing of the pool cleaning robot into an inner space or cavity within the pool cleaning robot where the filtering unit may be accommodated, such that the filtering unit may be accessible to and / or fluidly engageable by water streams and / or jets projected by the pop-up sprinkler when operated in emerged position. Once inside the pool cleaning robot, the pop-up sprinkler may direct water streams or jets toward the filtering unit, for washing and cleaning thereof from dirt and / or the like collected thereon. A suction capabilities may also be provided to improve efficiency and better cleaning of the filters.

[0020] In some embodiments, arrival of the pool cleaning robot to the charging socket may trigger operation of an electric water tap or faucet being fluidically connected to the pop-up sprinkler, where upon a pressure of the water as streamed by the tap reaches or exceeds a threshold, the pop-up sprinkler may be forcibly induced as result of the pressure to emerge from the docking station automatically.

[0021] The pop-up sprinkler may be adapted to rotate around its axis and rinse clean the filtering unit for a predetermined period of time, e.g., several minutes and / or the like. Additionally or alternatively, a duration of a cleaning cycle may be dynamically determined according to the filtering unit’s status, which may be detected in an autonomous and / or automated manner, e.g., using data from one or more sensors adapted for indicating that an excess amount of debris had accumulated, and / or the like. At the end of the period, the tap may close down and as the water pressure stops, the pop-up sprinkler may return back to its original position at the docking station.

[0022] In some embodiments, the pop-up sprinkler may be configured to operate under different pressure settings to accommodate varying cleaning requirements. A pressure regulation system may be provided to adjust water pressure output from low-pressure gentle rinsing to high-pressure intensive cleaning modes. The pop-up sprinkler may optionally operate in a headless configuration where water streams are distributed through multiple apertures rather than a concentrated single outlet. The position and orientation of the sprinkler head may be selectively adjustable both horizontally and vertically within the container. In some embodiments, the sprinkler head may be mounted on a multi-axis positioning mechanism allowing rotation around vertical and horizontal axes to direct water streams at optimal angles for comprehensive filter coverage. Additionally, the system may include a suction head positioned adjacent to or integrated with the sprinkler head to simultaneously extract dirty water and debris during the cleaning process, thereby preventing recirculation of contaminated water.

[0023] In some embodiments, the docking station may comprise a camera having a field of view coinciding and / or intersecting at least in part with the interior of the pool cleaning robot and / or its filter portion to be washed by the pop-up sprinkler. The camera may be adapted to operate concurrently with the pop-up sprinkler and capture imagery data of interest to a user and / or to the operation of the docking station, for example, to provide control and / or record of the washing process when executed, provide indication to cleaning of the filter, and / or the like. Optionally, the imagery data captured may be stored and analyzed in optimization of the washing process settings, e.g. the preset washing time period and / or the like. The analysis may employ artificial intelligence (Al) and / or likewise tools and / or techniques.

[0024] In some embodiments, the camera may be specifically positioned to monitor the quality and clarity of water being expelled from the filtering unit during the cleaning process. The camera may capture real-time imagery of the rinsed water flow, analyzing the level of debris, discoloration, and turbidity to determine filter cleanliness status. Clean, clear rinsed water flowing from the filtering unit may signal completion of the cleaning cycle, while cloudy or debris-laden water may indicate continued cleaning is required. The system may employ image processing algorithms to automatically assess water clarity by analyzing pixel intensity, color saturation, and particle detection within the captured imagery. When the analysis determines that the rinsed water has reached a predetermined cleanliness threshold — indicating the filtering unit has been adequately cleaned — the system may automatically terminate the cleaning cycle. This automated detection prevents over-cleaning while ensuring thorough filter maintenance, optimizing both water usage and cleaning effectiveness.

[0025] In some embodiments, the docking station may comprise a container where the pop-up sprinkler may be housed in. The container and pop-up sprinkler may be located within an elevated platform of the docking station onto which the pool cleaning robot may climb aboard via a linear slope in order to dock after completion of its pool cleaning tasks, and once docked may optionally undergo one or more self-maintenance operations such as charging, washing, filtering unit cleaning, and / or the like, as may be required. The container may be configured in size and shape to be substantially aligned with the opening of the pool cleaning robot when docking position is assumed by the pool cleaning robot. The container may comprise at its bottom edge a net for filtering water and dirt spillage that may enter the container during the wash and / or otherwise fall down into it from the pool cleaning robot via the opening. The container may be fluidically connected at its bottom to a drain or canal for draining and removing the excess water and / or dirt remains. Additionally or alternatively, the container may be removably placed in the docking station, and may be taken out at an end of a cleaning cycle and / or periodically for emptying thereof. The drainage water may be diverted to watering plants, evicted to sewage, and / or likewise handled.

[0026] In some embodiments, the pool cleaning robot may comprise a hinged door or shutter at the opening of the pool cleaning robot adapted for selectively covering and uncovering the interior of the pool cleaning robot. The docking station may comprise a knob or protuberance, positioned at a same level with the door at the opening when the pool cleaning robot enters into docking position, and adapted to engage with a distal end of the door for pushing the door to rotate around its hinge axis and away from the opening so as to open up and uncover the opening and interior portion of the pool cleaning robot. The container whereat the pop-up sprinkler being housed within the docking station may be adapted to accommodate the door of the pool cleaning robot when turning on its hinge into an open position and / or closing back. The knob may be located relative to an entrance to the docking station such that the knob engages the door of the pool cleaning robot prior to the pool cleaning robot reaching the charging socket.

[0027] In some embodiments, the docking station may comprise a flap actuating element protruding at least partially outwardly of the docking station and located at or near an exit from the docking station, for example, at an end of the elevated platform where the linear slope downwardly therefrom to ground level may begin. The flap actuating element may be positioned at a level within an offset from an altitude at which the door and / or opening of the pool cleaning robot may be located when the pool cleaning robot is aboard the elevated platform of the docking station, corresponding to dimensions of the door and such that when the pool cleaning robot moves away from the charging socket and towards the exit from the docking station, the flap actuating element engages with the door and pushes it to close and cover the opening while the robot passes over the flap actuating element .

[0028] In some embodiments, the docking station may comprise a communication interface adapted to transmit to and / or receive communications from one or more other devices. The communication interface may be used to communicate with the pool cleaning robot, such as for example, during a time in which the pool cleaning robot is operated within the water pool and / or operated out of the water to be navigated towards the docking station and / or with other pool related device such as chlorinator, skimmer, and / or the like. Additionally or alternatively, the communication interface may be used to communicate with a user device, e.g. a mobile device and / or the like, via an application program adapted for providing a user with indications relating to the docking station, such as for example, alerts, reports, etc.

[0029] In some embodiments, there may be provided a water exiting device or mechanism adapted to allow the pool cleaning robot to get out of the water pool by climbing thereon. The water exiting device may be in a form of a ladder and / or the like, preferably deployed at an end of the water, e.g., at one of its comers, edges, and / or the like. The water exiting device may comprise and / or be coupled to one or more sensors for detecting presence, proximity, position, whereabouts, and / or the like of the pool cleaning robot. The water exiting device may further comprise and / or be coupled to a communication means such as a transceiver and / or the like adapted to communicate with the docking station via its communication interface to give notice of the pool cleaning robot exiting the water pool and heading towards the docking station, so as to allow preparatory actions by the docking station in prospect of arrival of the pool cleaning robot, provision of instructions from the docking station to the pool cleaning robot, such as for assistance in navigation thereof from the water exiting device to the docking station, and / or the like.

[0030] In some embodiments, the docking station may be adapted to output and / or otherwise provide status indications to a user, such as, for example, indications regarding status of the pool cleaning robot (e.g., that its battery is fully charged, its filter is clean, and / or the like), indications regarding operation of the docking station, e.g., that the charging and / or cleaning of the pool cleaning robot is in progress, terminated normally or abnormally, and so forth.

[0031] In some embodiments, the docking station may comprise a compartment for storing and / or charging a remote control for the pool cleaning robot that may be used by a user for communication with the pool cleaning robot alternatively or additionally to the communication via the application program on the mobile device of the user. Optionally the remote control may be adapted to communicate with the pool cleaning robot via sound waves.

[0032] In some embodiments, the docking station may include a central control unit comprising a microprocessor, non-volatile memory for storing operational parameters, and input / output interfaces for coordinating charging, cleaning, and monitoring functions. The control unit may execute predetermined operational sequences including: robot detection and verification, positioning confirmation, charging protocol initiation, cleaning cycle management, and status reporting to external devices. The control system may monitor charging progress through voltage and current sensing, automatically terminating charging when batteries reach full capacity or upon detection of charging anomalies. For cleaning operations, the control system may initiate cleaning cycles based on elapsed time since last cleaning, user commands received via communication interfaces, or sensor data indicating filter contamination levels. Communication capabilities may include wireless interfaces such as Wi-Fi (802.11 b / g / n / ac), Bluetooth, or cellular connectivity, enabling remote monitoring and control via smartphone applications or web-based interfaces. The system may transmit real-time status updates, maintenance notifications, and operational logs to designated user devices.

[0071] Some embodiments described in the present disclosure relate to a docking station 100 for a pool cleaning robot 102 that provides integrated charging and automated maintenance capabilities. The invention addresses the need for autonomous maintenance of pool cleaning robots, particularly the cleaning of filtering units 114 that accumulate debris during normal operation, while simultaneously providing battery charging capabilities to ensure continuous operation.

[0072] The disclosed docking station 100 may comprise an elevated platform 101 positioned outside of the water pool 200 that receives the pool cleaning robot 102 for example after completion of cleaning tasks and / or for charging. The docking station 100 integrates multiple maintenance functions including electrical charging through conductive and\or inductive power transfer mechanisms, automated filter cleaning through a pressure-activated pop-up sprinkler system 120, and optionally intelligent monitoring through camera-based assessment 110 of cleaning effectiveness. The system operates autonomously to detect robot arrival, initiate maintenance procedures, monitor cleaning progress, and complete maintenance cycles without user intervention.

[0073] The pool cleaning robot 102 may an access mechanism that provides selective access to the interior portion 115 containing the filtering unit 114. In some embodiments, this access mechanism comprises a hinged flap 118 that pivots about a hinge axis to open and close the access opening. However, the access mechanism is not limited to hinged door configurations and may alternatively comprise a magnetic latch system, a magnetic flex door, a flexible membrane or flap constructed from elastomeric material, a sliding cover, a removable panel, or other suitable closure mechanisms The access mechanism may be actuated by an opening element, which in the case of a hinged door embodiment may comprise a mechanical actuator, lever, or push rod that engages with and opens the flap 118. In other embodiments, the opening element may comprise a magnetic release mechanism, a latch release, or other suitable actuation device appropriate for the specific access mechanism employed. A closing mechanism may be provided to return the access mechanism to its closed position, which may comprise a spring biasing element within the door itself, flap actuating element 109 such as a roller, a separate spring-loaded bumper, or other biasing means that ensures secure closure after the cleaning operation is complete. The docking station 100 may mechanically operate this access mechanism through precisely positioned protuberances 107 and rollers 109 that automatically open and close the robot's access opening 166 during docking and departure sequences. This mechanical automation ensures reliable access to internal components while maintaining proper sealing during pool operation. A sealing maybe placed around the flap 118 to seal the respective opening in a closed state.

[0074] It should be understood that the various functions performed at the docking station 100 — including charging, washing, and data communication — may be performed independently or in any combination depending on the operational needs of the robot 102 and user settings. In some operational scenarios, the robot 102 may dock solely for battery charging without initiating a washing cycle. In other scenarios, the robot 102 may dock specifically for filter cleaning and debris removal while charging is not performed or is already complete. In further scenarios, the robot 102 may dock primarily for data transfer, software updates, or status communication with the docking station's communication interface, with or without concurrent charging or washing. The mechanical engagement of the charging contacts and the opening of the access flap 118 (or other access mechanism) occur substantially simultaneously upon proper docking alignment, but the activation of specific functions such as water flow for washing or power transfer for charging may be controlled independently through the docking station's control system or through communication between the robot 102 and the docking station 100.

[0075] The cleaning system utilizes a one or more pop-up sprinkler 120 housed within a container 103 that emerges under water pressure to extend into the robot's interior portion 115. The sprinkler 120 directs pressurized water streams toward the filtering unit 114 to remove accumulated debris, with cleaning effectiveness may be monitored by camera 110 analysis of water clarity. The system determines cleaning completion every defined period and / or automatically based on visual assessment of expelled water, optimizing cleaning duration while preventing over-cleaning.

[0076] The charging system may accommodate multiple power transfer methods including conductive charging through plug 112 and socket connections, and\or inductive charging through coils 310 positioned in the robot's propulsion unit 300 or lateral charging configurations 434. The modular design enables adaptation to various robot configurations while maintaining waterproof integrity essential for underwater operation.

[0077] Now referring to the accompanying drawings, wherein like reference numerals refer to like parts throughout the several views, the invention will be described in detail.

[0078] Referring initially to FIG. 1, which shows a perspective view of the docking station 100, the docking station 100 is adapted for deployment at a location outside of a water pool 200. The docking station 100 comprises an elevated platform 101 accessible via a linear approach slope or ramp 104 that enables the pool cleaning robot 102 to climb aboard for example after completion of pool cleaning tasks and / or for charging or as per as user command. The elevated platform 101 incorporates a container (depicted for example as 103 in FIG. 2) positioned to align with the robot's access opening 166 when docked, and houses the automated cleaning and charging systems described herein.

[0079] With reference to FIG. 2, which provides a side cross-sectional view of the docking station 100 with the pool cleaning robot 102 in a docked position, the operational relationship between the docking station 100 and robot 102 is illustrated. The docking station 100 comprises a charging unit 105 adapted to charge a rechargeable energy source of the pool cleaning robot 102 when docked. The charging unit 105 may include a charging socket adapted to engage with a corresponding plug 112 of the pool cleaning robot 102 for electrically connecting the systems. Additionally or alternatively, the docking station 100 and / or pool cleaning robot 102 may be adapted for wireless power transfer, wherein the docking station 100 comprises an inductive charging pad 106 for inductive charging. The pop-up sprinkler (depicted for example as 120 in FIG. 3) is shown in its extended position within the robot's interior portion 115, demonstrating the cleaning configuration wherein water streams are directed toward the filtering unit 114. The docking station 100 may be adapted for washing interior of the pool cleaning robot 102, particularly for cleaning the filtering unit 114 as described below and depicted in FIG. 5. The one or more pop-up sprinkler 120 is adapted to selectively and reversibly emerge from the docking station 100 and enter via the access opening 166 in the robot body into the interior portion 115 where the filtering unit 114 is accommodated. The filtering unit 114 thus becomes accessible to and fluidly engageable by water streams and jets projected by the one or more pop-up sprinkler 120 when operated in the emerged position. Once positioned inside the pool cleaning robot 102, the one or more pop-up sprinkler 120 directs water streams toward the filtering unit 114 for washing and cleaning debris collected thereon. Suction capabilities may also be provided to improve cleaning efficiency.

[0080] Arrival of the pool cleaning robot 102 at the charging socket of charging unit 105 or a cleaning phase or state may trigger operation of an electric water tap or faucet 128 fluidically connected to the one or more pop-up sprinkler 120 via hose 124. Software update maybe performed at this time. When water pressure streamed by the tap 128 the one or more pop-up sprinkler 120 may be forcibly induced by the pressure to emerge from the docking station 100 automatically.

[0081] The pop-up sprinkler 120 may be configured to automatically emerge from the container 103 in response to water pressure from the water supply. In some embodiments, the emergence mechanism operates in a binary fashion, wherein any water pressure above ambient conditions causes the pop-up sprinkler 120 to deploy from its retracted position within the container 103. The water pressure acts against the sprinkler mechanism, overcoming any retaining force and causing the sprinkler to extend upward into the interior portion 115 of the robot 102. When water pressure is removed or reduced to ambient levels, the pop-up sprinkler 120 retracts back into the container 103, either through gravitational force, spring action, or other mechanical biasing means.

[0082] In alternative embodiments, the pop-up sprinkler 120 may incorporate a pres sure- sensitive threshold mechanism that activates the sprinkler only when water pressure exceeds a predetermined threshold value. This threshold-based activation may be useful in installations where the water supply experiences minor pressure fluctuations that should not trigger sprinkler deployment.

[0083] The initiation of the washing cycle may be triggered by various mechanisms. In some embodiments, the arrival of the pool cleaning robot 102 at the docking station 100 and the mechanical engagement of the robot with the charging unit 105 automatically triggers the washing cycle, with water pressure being applied to activate the pop-up sprinkler 120. In alternative embodiments, the washing cycle may be initiated based on predetermined time intervals, wherein the docking station control system activates the water supply after the robot has been docked for a specified duration, ensuring that washing occurs at regular intervals regardless of docking frequency. In further embodiments, the washing cycle may be triggered by sensor feedback, such as detection of reduced water flow through the filter indicating clogging, or by manual user activation through the communication interface. The triggering mechanism may be configurable through user settings or automatically optimized based on learned usage patterns.

[0084] In some embodiments, the container 103 may be configured for removable installation, allowing the container to be periodically extracted from the docking station 100 for manual emptying and cleaning. Alternatively or additionally, the container 103 may be fluidically connected at its bottom to a drainage system, such as a drain line, sewage connection, or canal, enabling automatic discharge of accumulated debris and wash water. In further embodiments, the container 103 may be fluidically connected to a side drainage channel or peripheral collection system that diverts waste material away from the docking station area. The selection among these drainage configurations may depend on the installation environment and user preferences for maintenance convenience.

[0085] Turning to FIGs. 3-6 and FIG. 9, which illustrates the docking station 100 with the pop-up sprinkler mechanism 120 and the pop-up sprinkler mechanism 120 describing the pressure-activated emergence system and rotational cleaning head, the one or more pop-up sprinkler 120 is adapted to rotate around its longitudinal axis and rinse the filtering unit 114 for a predetermined period, such as several minutes. Additionally or alternatively, cleaning cycle duration may be dynamically determined according to the filtering unit's 114 status, detected autonomously using sensor data indicating debris accumulation levels. At the period's end, the tap 128 closes and as water pressure drops, the one or more pop-up sprinkler 120 returns to its original position within container 103.

[0086] The one or more pop-up sprinkler 120 may be configured to operate under different pressure settings to accommodate varying cleaning requirements. A pressure regulation system may adjust water pressure output from low-pressure gentle rinsing to high-pressure intensive cleaning modes. The one or more pop-up sprinkler 120 may optionally operate in a headless configuration where water streams are distributed through multiple apertures rather than a concentrated outlet. The sprinkler head position and orientation may be selectively adjustable both horizontally and vertically within the container 103, with optional mounting on a multi-axis positioning mechanism allowing rotation around vertical and horizontal axes for optimal filter coverage. Additionally, the system may include a suction head positioned adjacent to or integrated with the sprinkler head to simultaneously extract dirty water and debris, preventing re-circulation of contaminated water.The docking station 100 comprises at least one pop-up sprinkler 120, and in some embodiments may include multiple pop-up sprinklers positioned at different locations within the container 103 to provide comprehensive coverage of the filtering unit 114 interior. Each pop-up sprinkler 120 may be adapted to rotate 360 degrees around its longitudinal axis and direct water jets in multiple directions, ensuring thorough washing of the filter surfaces from various angles. In embodiments with multiple pop-up sprinklers, the sprinklers may be configured to operate simultaneously or sequentially, and may be positioned to target different zones within the robot's interior portion 115 for optimal cleaning efficiency. The number, positioning, and spray patterns of the pop-up sprinklers may be selected based on the specific geometry of the robot's interior, the type and size of filtering unit 114, and the typical debris accumulation patterns encountered during pool cleaning operations.

[0087] Referring also to FIG. 9, which provides a perceptive view of the docking station platform 101 showing guide rails 108 for guiding the pool cleaning robot 102 towards charging contacts, and container 103 positioning.

[0088] The docking station 100 may comprise a camera 110 having a field of view coinciding and / or intersecting at least in part with the interior portion 115 of the pool cleaning robot 102 and / or its filtering unit 114 to be washed by the one or more pop-up sprinkler 120. The camera 110 operates concurrently with the one or more pop-up sprinkler 120 and captures imagery data for user information and / or docking station operation, providing control and recording of the washing process, cleaning indication for the filtering unit 114, and similar functions. The imagery data may be stored and analyzed for washing process optimization, such as preset washing time periods, employing artificial intelligence (Al) and similar analytical tools.

[0089] In some embodiments, the docking station 100 may optionally comprise one or more optical sensors for monitoring various aspects of the cleaning and charging operations. The optical sensors may include, but are not limited to, one or more cameras 110 positioned to visually monitor water quality and clarity of water expelled from the filtering unit 114, spectroscopy-based sensors for analyzing chemical composition or contamination levels in the expelled water, turbidity sensors for measuring water clarity, colorimetric sensors, or other optical detection devices. The optical sensors may be positioned at various locations around the docking station 100, including above, beside, or below the container 103, to provide optimal monitoring of the washing process. Data from these optical sensors may be analyzed to provide feedback on filter cleanliness, assess pool water quality, generate recommendations for pool treatment or maintenance, or determine when the cleaning cycle is complete based on water clarity improvement. It should be noted that optical sensors are optional components, and the docking station 100 may function without optical monitoring in simpler implementations.

[0090] The camera 110 may be specifically positioned to monitor water quality and clarity expelled from the filtering unit 114 during cleaning. The camera 110 captures real-time imagery of rinsed water flow, analyzing debris levels, discoloration, and turbidity to determine filter cleanliness status. Clean, clear rinsed water signals cleaning cycle completion, while cloudy or debris-laden water indicates continued cleaning requirements. Image processing algorithms automatically assess water clarity by analyzing pixel intensity, color saturation, and particle detection within captured imagery. When analysis determines that rinsed water has reached a predetermined cleanliness threshold — indicating adequate filter cleaning — the system automatically terminates the cleaning cycle, preventing overcleaning while ensuring thorough maintenance and optimizing water usage and cleaning effectiveness.

[0091] Upon completion of a cleaning cycle or when battery charge falls below a predetermined threshold, the pool cleaning robot 102 exits the water pool 200 and navigates across the surrounding deck or ground surface toward the docking station 100, which is positioned at a safe distance from the pool edge to maintain electrical safety. The robot 102 may also exit the pool and return to the docking station 100 for intermediate charging during extended cleaning operations, such as when cleaning large pools or pools with heavy debris accumulation, and subsequently return to the pool to complete the cleaning cycle. Thus, the robot's return to the docking station 100 is not limited to postcleaning operations but may occur at any time charging, washing, or data

[0092] communication is needed.

[0093] one or more pop-up sprinkler 120one or more pop-up sprinkler 120The container 103 and one or more pop-up sprinkler 120 are located within the elevated platform 101 onto which the pool cleaning robot 102 climbs via the linear slope 104 to dock after getting out of the pool. Once docked, the robot 102 may undergo self-maintenance operations such as charging, washing, filter cleaning, and similar procedures as required data and software updating. The container 103 is configured in size and shape to substantially align with the access opening 166 of the pool cleaning robot 102 when assuming the docked position. The container 103 may comprise at its bottom edge a net 113 for filtering water and dirt spillage entering during washing and / or falling from the pool cleaning robot 102 via the access opening 166. The container 103 may be fluidically connected at its bottom to a drain or canal for removing excess water and dirt remains. Additionally or alternatively, the container 103 may be removably placed in the docking station 100 and removed at cleaning cycle end and / or periodically for emptying. Drainage water may be diverted to plant watering, sewage systems, and / or otherwise handled appropriately.

[0094] The charging unit 105 may employ various power transfer methodologies depending on the specific implementation. In some embodiments, the charging unit 105 utilizes conductive charging through direct electrical contact between charging contacts on the docking station and corresponding contacts on the robot 102. In other embodiments, the charging unit 105 employs inductive charging, wherein power is transferred wirelessly through electromagnetic induction between a charging coil in the docking station and a receiving coil in the robot 102. In yet other embodiments, the charging unit 105 may incorporate a hybrid system that includes both conductive and inductive charging capabilities, providing redundancy and flexibility in power transfer. The selection of charging methodology may be based on factors such as power transfer efficiency requirements, environmental considerations, and design preferences.

[0095] Referring to FIG. 6, which provides a cross-sectional view of the pool cleaning robot 102 showing the hinged door mechanism, interior portion 115, and filtering unit 114 placement, the pool cleaning robot 102 comprises a flap such as a hinged flap 118 or shutter at the access opening 166 adapted for selectively covering and uncovering the interior portion 115. The docking station 100 comprises a knob or protuberance 107 positioned at the same level as the flap 118 at access opening 166 when the pool cleaning robot 102 enters the docked position. The protuberance 107 engages with a distal end of the flap 118, pushing the flap 118 to rotate around its hinge axis away from the access opening 166 to open and uncover the access opening 166 and interior portion 115. The container 103 housing the one or more pop-up sprinkler 120 within the docking station 100 is adapted to accommodate the flap 118 when turning on its hinge into open position and / or closing back. The protuberance 107 is located such that it engages the flap 118 prior to the pool cleaning robot 102 reaching the charging socket.

[0096] The docking station 100 may comprises a flap actuating element 109 such as a roller, a leafspring, or any proterustion, is protruding at least partially outwardly and located at or near the docking station exit, for example, at the elevated platform 101 end where the linear slope 104 begins downwardly to ground level. The flap actuating element 109 is positioned at a level within offset from the altitude where the flap 118 and / or access opening 166 are located when the pool cleaning robot 102 is aboard the elevated platform 101, corresponding to flap 118 dimensions such that when the pool cleaning robot 102 moves away from the charging socket toward the exit, the flap actuating element 109 engages with the flap 118 and pushes it to close and cover the access opening 166 while the robot 102 passes over the flap actuating element 109.

[0097] With reference to FIG. 7, which illustrates a detailed view of the pool cleaning robot 102 leaving the pool and moving towards a docking station for charging . The charging may be conductive and / or inductive. The pool cleaning robot 102 may perform cleaning tasks in the water pool 200, such as cleaning dirt at the pool floor. The pool cleaning robot 102 may then travel from the water pool 200 to the docking station 100, for example, upon cleaning cycle completion, due to operational status requiring maintenance actions such as low battery and / or clogged filtering unit 114, and / or for other similar reasons or according to user command for pick up. The pool cleaning robot 102 may exit the water pool 200 using exiting mechanism 202 and head toward the docking station 100. The pool cleaning robot 102 may position and orient itself appropriately for docking and navigate to the docking station 100 automatically, utilizing imagery data from a mounted camera and / or other sensors providing spatial information for automatic positioning and orientation during docking procedures.

[0098] The docking station 100 may comprise a communication interface adapted to transmit and / or receive communications from other devices. The communication interface may communicate with the pool cleaning robot 102, such as during operation within the water pool 200 and / or with other pool-related devices such as chlorinators, skimmers, and similar equipment, user such as an operator using an application app, and / or a management server. Additionally or alternatively, the communication interface may communicate with user devices, such as mobile devices, via application programs adapted for providing users with docking station indications, such as alerts, reports, etc. The docking station 100 may include a central control unit comprising a microprocessor, memory, and I / O interfaces for coordinating charging, cleaning, and monitoring operations. The control system may execute programmed sequences including robot detection and positioning verification, charging initiation and monitoring, cleaning cycle activation based on time, sensor data, or manual command, safety shutdown procedures, and status reporting to external devices. Communication interfaces may include Wi-Fi, Bluetooth, or cellular connectivity for remote monitoring and control.

[0099] The automated cleaning cycle operation may be monitored by sensors such as proximity sensors , ultrasonic sensors, infrared sensors, or capacitive sensors positioned around the docking platform perimeter with sensor range of 10- 100cm to detect robot approach and position. Weight sensors may comprise load cells or strain gauges integrated into the platform structure, calibrated to detect robot weight and distinguish robot presence from other objects. Sensor data may be processed by a microcontroller using algorithms that trigger charging initiation, sprinkler activation, or status notifications based on predetermined sensor thresholds.

[0100] While the illustrated embodiments show water pressure for deploying the pop-up sprinkler 120, alternative embodiments may employ other mechanical actuation means. For example, the popup sprinkler 120 may be actuated by an electric motor or solenoid that extends and retracts the sprinkler based on control signals from the docking station control system. In other embodiments, a pneumatic or hydraulic actuator may be used to deploy and retract the sprinkler 120. In yet other embodiments, a cam mechanism, linkage system, or other mechanical arrangement triggered by the robot's docking position may cause the sprinkler 120 to emerge. The choice of activation mechanism may depend on factors such as system complexity, reliability requirements, available power sources, and cost considerations.

[0101] The camera 110 or camera system may comprise a digital imaging sensor with resolution of at least 1080p, equipped with LED illumination for operation in low-light conditions within the robot cavity 115. The camera 110 may be positioned at an angle of 15-45 degrees from vertical to optimize viewing of both the filter cleaning process and water clarity assessment. Image processing algorithms may include edge detection for debris identification, color analysis for water clarity measurement, and motion detection for monitoring cleaning progress. The camera housing may be waterproof rated to IP67 or higher to withstand splashing during cleaning operations.

[0102] Additional sensor systems may include turbidity sensors for direct water quality measurement, flow sensors for monitoring cleaning water circulation, temperature sensors for environmental monitoring, and vibration sensors for detecting robot movement or positioning errors. The sensor data may be processed using machine learning algorithms that adapt cleaning parameters based on historical performance data, seasonal variations, or specific pool conditions. Predictive maintenance algorithms may analyze sensor trends to schedule preventive maintenance before component failures occur. Safety features may include ground fault circuit interruption (GFCI) protection for electrical components, pressure relief valves for water systems, emergency stop mechanisms, and fault detection algorithms.

[0103] The docking station 100 may comprise a pair of rails 108, guides, notches, and similar structures provided at each lateral side along the surface of the elevated platform 101. The rails 108 may be adapted to engage with and align and maintain course of a drive mechanism, such as wheels, tracks, and similar components by which mobility of the pool cleaning robot 102 may be enabled, such that deviation from course and / or fall of the pool cleaning robot 102 from the docking station 100 may be prevented. The guide rails 108 may comprise parallel tracks or channels formed in the platform surface, spaced apart by a distance corresponding to the robot's drive wheel spacing. Rails 108 may be raised 5-15mm above the platform surface or recessed 3-10mm below the surface. Rail material may be polyurethane and / or of a material having an elasticity of 85 SHOR for example with low-friction surfaces to facilitate smooth robot movement. Rails 108 may include lead-in chamfers or tapered sections at the platform entrance to assist robot alignment during approach. The rails 108 may extend beyond the charging position to provide overrun area preventing robot deviation.

[0104] Reference is now made to FIG. 10A, which provides a detailed isometric view of the pool cleaning robot's propulsion unit showing the sealed waterproof housing 300, and to FIG. 10B, which provides a detailed cross-sectional isometric view of the sealed waterproof housing 300 of FIG. 10A and the inductive charging coil 310 positioning and motor mounting therein. In these embodiments, the sealed waterproof housing 300 comprises a main housing body 302 formed from waterproof material suitable for underwater pool operations. The housing body 302 defines an internal cavity 304 configured to accommodate various electrical and mechanical components of the propulsion unit.

[0105] The sealed waterproof housing 300 may be formed from ABS plastic, polycarbonate, or aluminum with wall thickness of 2-8mm. Sealing may be achieved through O-ring seals in machined grooves with compression of 15-25%. The inductive charging coil 310 may comprise 50-200 turns of copper wire wound on a ferrite core, positioned l-5mm from the housing bottom surface 312. Charging control circuitry 320 may include rectification, voltage regulation to 12V or 24V, and current limiting to 1-10 amperes. The electrical cable connector 322 may comprise waterproof circular connectors rated for underwater use with locking mechanisms to prevent accidental disconnection.

[0106] At least one propulsion motor 306 is disposed within the sealed housing 300, positioned to drive propulsion mechanisms for providing thrust during pool cleaning operations. The propulsion motor 306 is secured within the internal cavity 304 through appropriate mounting brackets 308. The propulsion motor 306 may be encircled with sealing comprising multiple redundant barriers: an outer O-ring of shore hardness 70-90 durometer in a precision-machined groove, an intermediate elastomeric gasket of 2-5mm thickness providing backup sealing, and an inner dynamic seal assembly comprising a lip seal or mechanical seal rated for continuous rotation at 100-3000 RPM. Sealing materials may include NBR, EPDM, or Viton rubber compounds selected for chlorine resistance and temperature stability. The sealing assembly may be preloaded to maintain contact pressure of 5-15 psi at the sealing interfaces.

[0107] An inductive charging coil 310 is positioned within the sealed housing 300 and oriented to face toward a charging station when the pool cleaning robot 102 is docked. In this embodiment, the inductive charging coil 310 is mounted at a bottom surface 312 of the sealed housing 300. The inductive charging coil 310 may have a maximum outer diameter of approximately 65mm and is mounted to a printed circuit board having fixture holes for mechanical attachment.

[0108] A holder 318 secures the inductive charging coil 310 within the sealed housing 300 with a press fit of approximately 0.5mm, ensuring stable positioning during underwater operations while maintaining the waterproof integrity of the housing 300. Charging control circuitry 320 is electrically connected to the inductive charging coil 310 and disposed within the sealed housing 300. The charging control circuitry 320 includes power conditioning circuitry for converting received inductive power to suitable form for battery charging operations.

[0109] An electrical cable connector 322 is mounted on a wall 324 of the sealed housing 300 through a sealed wall penetration 326. The electrical cable connector 322 provides electrical connection means for connecting the propulsion unit to a separate waterproof battery assembly 380 located within or on the robot system. The sealed wall penetration 326 maintains the waterproof integrity of the housing 300 while allowing electrical connectivity. A thermal management system is thermally coupled to the charging control circuitry 320 and may include a heat sink positioned adjacent to an inner wall of the sealed housing 300 for effective heat dissipation during charging operations. Optionally, conductive charging contacts may be positioned at the same location as the inductive charging coil 310, creating a hybrid charging interface capable of both inductive and conductive charging methods.

[0110] The sealed waterproof housing 300 is configured for removable attachment to different pool cleaning robot body configurations while maintaining waterproof sealing integrity. Sealing gaskets and appropriate fastening mechanisms ensure reliable waterproof performance during detachment and reattachment operations. With reference to the sealed waterproof housing 300 described in FIG.

[0111] 10A, the inductive charging coil 310 is specifically mounted at the bottom surface 312 of the sealed housing 300. This bottom-mounting configuration optimizes the wireless power transfer interface by positioning the charging coil 310 in direct alignment with the charging pad 106 of the docking station 100 when the pool cleaning robot 102 assumes its docked position on the elevated platform 101. The bottom surface 312 includes a recessed charging well 370 that accommodates the inductive charging coil 310 while maintaining a substantially flush exterior surface to minimize water turbulence during underwater operations. The charging well incorporates a transparent or translucent waterproof window that allows electromagnetic field penetration while preserving the sealed integrity of the housing 300.

[0112] Optionally, this embodiment incorporates conductive charging contacts positioned at the same location as the inductive charging coil 310, creating a charging interface optionally hybrid which is capable of both inductive and conductive charging methods. Optionally, the battery assembly 380 is housed in a separate sealed waterproof compartment 382 distinct from the propulsion unit housing 300. The battery compartment 382 is positioned at a location within the robot body determined by structure requirements of the robot system. Specifically, the battery assembly 380 may be positioned in an upper forward section 384 of the main robot body to counterbalance the weight of the propulsion unit 300 located in a lower rear section 386. The electrical cable connector 322 accommodates an extended electrical cable 388 with sufficient length and flexibility to span the distance between the propulsion unit 300 and the optimally positioned battery compartment 382, while maintaining waterproof connectivity through sealed cable routing channels 390 within the robot body structure.

[0113] Optionally, the battery assembly 380 may be located within the robot system in a position that is not directly accessible for charging, such as an internal cavity completely enclosed within the robot body structure. The battery assembly 380 is permanently sealed within the internal cavity during manufacturing, with charging performed exclusively through the propulsion unit 300 via the electrical cable connector 322. This configuration eliminates potential leak points that could be introduced by direct access ports to the battery assembly 380, while still enabling effective charging through the propulsion unit's 300 electrical connectivity to the primary robot power systems. The electrical cable connector 322 is mounted on the sealed wall penetration 326 and configured to electrically connect to the cable 388 connected to the battery assembly 380 external to the propulsion unit 300. This modular design enables the propulsion unit 300 to be manufactured, tested, and serviced as an independent component while maintaining complete waterproof integrity.

[0114] Reference is now made to FIGs. 11A and 11B, which show isometric views of an exemplary robot body 425 having lateral tracks or wheel protector 426 with an opening 427 for an inductive charging coil 434 and an isometric view of this exemplary robot body 425 with the wheel protector 426 removed, both according to some embodiments of the present invention. In this embodiment the robot body 425 has lateral walls and drive wheels. A waterproof charging unit 430 is integrated into the robot body 425, comprising a waterproof enclosure 432 and an inductive charging coil 434 mounted parallel to and flush with one of the lateral walls of the robot body 425. The inductive charging coil 434 is positioned between the mounts 420a, 420b of drive wheels along the lateral wall. Charging electronics 436 are disposed within the waterproof enclosure 432 and electrically connected to the inductive charging coil 434. Electrical connections 438 extend from the charging unit 430 to a battery assembly located separately within the robot body 425. This configuration enables inductive power transfer through the lateral wall when the robot is positioned adjacent to a side-mounted charging station.

[0115] Optionally, the sealed waterproof housing 300 and / or the waterproof charging unit 430 is removably attachable to different pool cleaning robot body configurations while maintaining waterproof sealing integrity. Universal mounting interfaces include standardized connection ports, alignment features, and sealing gaskets 336 that accommodate various robot body designs. Quickdisconnect fastening mechanisms may enable field replacement of the propulsion unit 300 without compromising waterproof sealing performance across different robot platforms.

[0116] Reference is now made to FIG. 12, which provides a flowchart of a method utilizing the hardware configuration of FIG. 10A. As shown at 1201, the method involves positioning the pool cleaning robot 102 having the bottom- mounted inductive charging coil 310 over the charging station 100. Then, as shown at 1202, inductive power transfer is activated from the charging station 100 upward to the bottom-mounted coil 310. The received inductive power is converted using the charging control circuitry 320 within the waterproof propulsion unit 300 as shown at 1204. This allows, as shown at 1205, conducting the converted power via the electrical cable 388 through connector 322 to the separately located waterproof battery assembly 380 within the robot body.

[0117] As shown at 1206, the method may include guiding the robot 102 onto the elevated docking platform 101 of station 100 outside of the pool 200, and as shown at 1207, optionally automatically opening the flap 118 via mechanical engagement with the protrusion 107 as the robot 102 moves into docking position, wirelessly charging the battery assembly 380 through the inductive charging coil 310 integrated within the waterproof propulsion unit 300. This allows, as shown at 1208, automatically activating the one or more pop-up sprinkler 120 when water pressure exceeds the threshold and / or as shown at 1209, washing the filter 114 by directing water streams from the emerged sprinkler 120 into the robot interior portion 115, and optionally as shown at 1210, automatically closing the flap 118 via mechanical engagement with the flap actuating element 109 as the robot 102 exits the docking station 100.

[0118] The method may include detecting arrival of the robot 102 at the docking station 100 via sensors integrated with the charging control circuitry 320, communicating status information between the robot 102 and docking station 100 during maintenance operations through wireless communication interfaces 444, and transmitting maintenance completion notifications to a user device via wireless communication interface 446.
