[0021] The terms "include", "comprising", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but may also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by "includes..." does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0022] refer to Figures 1 to 3 and Figure 5, reference numeral 10 is generally designated as a cleaning tool for a surface cleaner. In some specific implementations, the surface cleaner is in the form of an extraction cleaner 14 including an attachment hose 18 and a suction source 22. The hose 18 is in fluid communication with the suction source 22. The cleaning tool 10 is adapted to be coupled to the hose 18. The cleaning tool 10 includes a tool body 26, which defines a suction path 30 that is fluidly communicated with the suction source 22. The tool body 26 includes a removable tank 34 that defines an entry opening 36 leading to a reservoir 38. A suction nozzle 40 on the tool body 26 defines a suction nozzle inlet 42 that is communicated with the suction path 30. The suction nozzle 40 includes a lens 46, and the lens 46 defines a suction channel 50. The tool body 26 also includes a connector portion 54 that defines an outlet 58 to the suction path 30 and is configured to selectively couple the cleaning tool 10 to the hose 18. In some aspects, lens 46 is adjustable between at least a first position and a second position, wherein in the second position lens 46 extends outwardly and the volume of suction channel 50 is increased.

[0023] Portable surface cleaning equipment (such as Figure 3 The extraction cleaner 14 (shown in dashed lines in FIG. 1 and as described herein) can perform the same or similar functions as an upright surface cleaning device. Portable surface cleaning devices (e.g., portable extraction cleaners) and upright surface cleaning devices can provide suction to extract debris from or on the lower surface. Although various aspects of the present disclosure are described with respect to the extraction cleaner 14, it is within the scope of the present disclosure that the surface cleaning device includes any suitable cleaner, including but not limited to various extraction cleaners, handheld cleaners, and upright surface cleaning devices. Therefore, the cleaning tool 10 can be used with an attachment hose of any surface cleaner, including a dry vacuum cleaner.

[0024] The illustrated extractor cleaner 14 can be in the form of a wet extractor cleaner, and is merely an exemplary application of various aspects of the present disclosure. Therefore, it should be understood that various aspects and features of the present disclosure can be used for other wet extractor cleaner configurations and for any logically related type of deep cleaning system. In addition, only the selected components of the extractor cleaner system and the cleaning assembly are shown and described in detail below. However, the system components discussed herein may include many additional and alternative features for carrying out the various methods and functions of the present disclosure, as well as other available peripheral components. Non-limiting examples of extractor cleaners that can be utilized with cleaning tool 10 are disclosed in U.S. Patent No. 9,474,424, U.S. Patent No. 8,549,697, U.S. Patent No. 7,073,226, U.S. Patent No. 10,188,252 and U.S. Patent No. 9,107,558, the contents of which are incorporated herein by reference as a whole.

[0025] See now Figure 1 and Figure 3 , various functional subsystems of extractable cleaner 14 are shown in schematic block diagram.These functional subsystems can be arranged into any desired configuration, including upright extractable device, tank type extractable device, pod type extractable device, handheld extractable device, autonomous and robot cleaning device and commercial cleaner.Cleaning tool 10 can be connected with extractable cleaner 14 to provide suction and / or cleaning fluid is delivered to surface to be cleaned.Therefore, extractable cleaner 14 can include the housing 62 of various parts and functional systems that accommodate extractable cleaner 14.Recovery assembly 70 can be provided for removing and temporarily storing (for example, in recovery tank) debris and / or unnecessary cleaning fluid from surface.Fluid delivery system 74 can be provided for cleaning fluid is distributed to surface.

[0026] like Figure 3 As shown, the exemplary extraction cleaner 14 includes a hose 18 or "flexible hose" that can be selectively fluidly coupled to the cleaning tool 10 and forms at least a portion of the suction path 30 passing therethrough. In some aspects, the flexible hose 18 can provide a fluid delivery path and an airflow path from the extraction cleaner 14 to the cleaning tool 10. Likewise, the cleaning tool 10 can be coupled to the hose 18 via a connector portion 54. Thus, the cleaning tool 10 is adapted to be coupled to the hose 18. As shown, the cleaning tool 10 can be coupled to a wand 78 that is coupled to the distal end of the hose 18. Optionally, the wand 78 or cleaning tool 10 includes a spray trigger 82 ( Figure 4 ), which can be depressed to activate the liquid delivery state. In some aspects, the size of the rod 78 is designed to operate as a "handle", and the spray trigger 82 can be located on the bottom side of the rod 78.

[0027] The connector portion 54 may define a hole 86 that is configured to receive a tab 90 on the wand 78. In this way, the hose 18 can be slid into engagement with the connector portion 54, wherein the tab 90 is retained within the hole 86. When the tab 90 is depressed and the hose 18 is pulled away from the connector portion 54, the hose 18 can be removed from the connector portion 54. However, the connector portion 54 may include any suitable retention features to selectively couple the cleaning tool 10 to the hose 18 of the extraction cleaner 14. For example, where the connector portion 54 relies on a transition fit with the hose 18, the hole 86 and the tab 90 may be omitted. In another example, the connector portion 54 may be in the form of a clamp configured to retain the hose 18 thereto.

[0028] Go to Figures 5 and 6, the fluid delivery system 74 is in fluid communication with the cleaning tool 10, which may include at least one fluid distributor 94. The fluid distributor 94 may include one or more distributor outlets 98 for spraying the cleaning fluid onto the surface being cleaned. The distributor outlet 98 may be disposed on or within the cleaning tool 10 to deliver the fluid onto the surface. In some aspects, the fluid distributor 94 is positioned at the inlet of the suction nozzle inlet 42. The distributor outlet 98 may include any suitable structure, such as a distributed arrangement of nozzles or spray heads or distributor outlets 98. For example, as Figure 6 As shown, the fluid distributor 94 includes a plurality of outlets 98 aligned in series for dispensing the cleaning fluid to the surface. An optional fluid heater 100 ( Figure 1 ) can be fluidly interposed between a fluid container associated with the extraction cleaner 14 and the fluid dispenser 94 to selectively heat the cleaning fluid before the cleaning fluid is delivered to the surface through the dispenser outlet 98 (e.g., via the liquid pump 101). In another example, the exhaust gas from the motor cooling exhaust path of the suction source 22 can be used to heat the cleaning fluid.

[0029] The suction source 22 carried by the extraction cleaner 14 is in fluid communication with the nozzle inlet 42 of the cleaning tool 10 and is configured to generate a working air flow through the suction path 30. The suction path 30, which may be an "airflow" path, extends from the nozzle inlet 42 through the cleaning tool 10, through the hose 18, and through the extraction cleaner 14 to the suction source 22 (e.g., a motor). Figure 5 As shown, the suction path 30 through the cleaning tool 10 includes the suction nozzle inlet 42 of the suction nozzle 40, passes through the tank 34, and exits the tool body 26 at the outlet 58. The suction source 22 can be positioned in the main housing 62 ( Figure 3 ). Thus, the suction source 22 can generate a working airflow to draw liquid and entrained debris through the cleaning tool 10 into the suction path 30.

[0030] As used herein, the term "debris" may include dirt, dust, soil, hair, large pieces of debris, loose materials or other messy matter, etc. As used herein, the term "recovery fluid" mainly covers liquids recovered from surfaces, and may include water, gunk, grime, dirty compositions, cleaning fluids, etc., or mixtures thereof. As used herein, the term "cleaning fluid" mainly covers liquids provided to surfaces, and may include steam, water, compositions, concentrated detergents, diluted detergents, fragrances, deodorants, etc., or mixtures thereof.

[0031] refer to Figure 4 and Figure 5, cleaning tool 10 comprises tool body 26, and this tool body comprises suction nozzle 40, tank 34, cover 102, joint part 54 and agitator block 106.Agitator block 106 can be adjacent to suction nozzle 40 and can be connected with suction nozzle 40.As shown in the figure, suction nozzle 40 is arranged at the front end of cleaning tool 10, and joint part 54 is arranged at the rear end of cleaning tool 10, and tank 34 is located therebetween.Suction nozzle 40 can comprise lens 46.Lens 46 can be in the form of cover plate, and in some examples, this cover plate is at least partially transparent, so that the user can observe the inside of suction nozzle 40.The positioning of lens 46 can limit the airflow along the front end of tool body 26, thereby defining suction channel 50.Used cleaning liquid, dirt and other entrained debris can enter suction channel 50 and travel to tank 34 via suction path 30 (working airflow), wherein it can be collected and prevented from entering hose 18.

[0032] In some examples, the cover 102 selectively covers the access opening to the reservoir 38 (e.g., the cover 102 is removable). The cover 102 can be removed from the canister 34 and / or the tool body 26 using any suitable design (such as a threaded / twist-on connection, a snap-fit ​​connection, etc.). In one example, the retaining protrusion 104 ( Fig.11 ) is configured to couple the cover 102 to the tool body 26. The cover 102 may be an intermediate component that couples the canister 34 to the tool body 26. The tool body 26 may define a first channel 118 and a second channel 122. Figure 5 As shown, the first channel 118 is fluidly coupled to the first hole 126 defined by the cover 102, and the second channel 122 is fluidly coupled to the second hole 130 defined by the cover 102. A first screen 134 and a second screen 138 may be disposed in the first hole 126 and the second hole 130, respectively. The first screen 134 and the second screen 138 may be in the form of debris screens that prevent particles that are too large from moving through them (e.g., the mesh size is about 75 μm, but is not limited thereto). The first screen 134 and the second screen 138 may be coupled to the cover 102 by a frame 142. In some aspects, the frame 142 is in the form of a gasket. Air and entrained liquid and debris may enter the tank 34 through the first baffle 146 (adjacent to the channel 118). When the working airflow leaves the tank 34 through the second baffle 147 (adjacent to the channel 122), the entrained liquid and debris may be captured in the tank 34 and may then travel through the hose 18. The first baffle 146 and the second baffle 147 may each be coupled to one of the frames 142. Thus, the first baffle 146 may be adjacent to the first screen 134, and the second baffle 147 may be adjacent to the second screen 138. Figure 5As shown, the open ends 148 of the baffles 146, 147 face away from each other (e.g., the baffles 146, 147 are in opposite orientations), which can promote the separation of air and debris. However, it is within the scope of the present disclosure that the baffles 146, 147 are oriented in any direction, which may include being perpendicular to each other. As shown, the baffles 146, 147 may include a spherical shape. It has been found that by positioning the baffles 146, 147 in a relative manner, the airflow can be reduced so that the suction air can enter the baffle 147 adjacent to the second channel 122, while the liquid and entrained debris can be drawn out through the baffle 146 adjacent to the first channel 118, thereby separating the air and fluid debris.

[0033] The first screen 134 and the second screen 138 may include the same mesh size or different mesh sizes. In some examples, the mesh size of the first screen 134 is greater than the mesh size of the second screen 138. In this way, larger particles may be able to enter the reservoir 38, but will be prevented from advancing toward the outlet 58. Therefore, these larger particles can be maintained by the cleaning tool 10 without entering the recovery assembly 70 of the extraction cleaner 14. Advantageously, the user can remove the tank 34 coupled with the cap 102 and pour any liquid (e.g., when the cap 102 is in place) from the reservoir 38 to filter solid debris. The user can then remove the cap 102 and approach the reservoir 38 to easily remove the solid debris, which will be suitable for directly emptying into a garbage container.

[0034] Still see Figure 4 and Figure 5 , the illustrated tank 34 comprises a flared shape that widens toward the bottom of the tank 34. The flared shape can increase the storage tank capacity and is conducive to a wider effective range of use orientation. Therefore, the user can tilt the cleaning tool 10 forward during the cleaning operation, and due to the tilted orientation of the tank 34 sidewalls, the contents of the reservoir 38 can fill a wider bottom area before entering the first hole 126. As shown, the bottom wall 144 of the tank 34 is flat. Although illustrated as a flared tank with a flat bottom wall 144, the tank 34 may include any suitable configuration. For example, the bottom wall 144 may include a convex or concave shape, but is not limited thereto. In another example, the sidewall of the tank 34 may be roughly straight.

[0035] like Figure 5 and Figure 6As shown, the fluid distributor 94 includes a plurality of outlets 98 disposed in the suction channel 50. A plurality of outlets 98 may be limited on a single fluid distributor 94 or on a plurality of fluid distributors 94. For example, the fluid distributor 94 may be in the form of a spray bar 150 having a plurality of outlets 98. In a specific implementation, a plurality of outlets 98 may be aligned in series (e.g., positioned in line). In another example, the fluid distributor 94 may include a plurality of fluid distributors 94, which may be in the form of a nozzle or a spray head, each nozzle or spray head having a single outlet 98. The fluid distributor 94 may be coupled to at least one fluid fitting 152 (e.g., a barbed fitting). In some examples, the inlet of the fluid fitting 152 is configured to be coupled to a fluid delivery line 154 fluidly, which is fluidly connected to the fluid delivery system 74 of the extraction cleaner 14 to distribute the fluid onto the surface to be cleaned. The fluid delivery line 154 may extend through or on the tool body 26 and, as illustrated herein in phantom, may include a flexible tube connecting an inlet of the fluid dispenser 94 with a fluid coupler associated with the fitting portion 54. However, it is within the scope of the present disclosure for the fluid dispenser 94 to include any suitable fluid connection to receive a supply of fluid from the fluid delivery system 74.

[0036] See now Figure 6 , Figure 7 and Fig.11 , showing the agitator block 106 in more detail. The agitator block 106 may be capable of being in an agitating position (e.g., Figure 6 ) and self-cleaning positions (e.g. Figure 7 ) between. The agitator block 106 can be in the form of a "strip" and can include a first surface 160 and a second surface 164. The first surface 160 can include a plurality of agitators extending therefrom, such as nubs 168. The second surface 164 can be planar or flat. In a particular implementation, the first surface 160 and nubs 168 are made of a material that is more flexible (e.g., including a Shore A hardness of about 50 or "medium soft") than the material used for the first surface 160, which can be made of a rigid plastic. The agitator block 106 can be configured to carry any suitable type of agitator or combination of agitator types, non-limiting examples of which include elastomeric protrusions, bristles, microfibers, etc.

[0037] In certain implementations, a lever 170 may be coupled to the agitator block 106 and accessible to a user to facilitate movement of the agitator block 106. Applying a force to the lever 170 may cause the agitator block 106 to rotate about the longitudinal axis of the nozzle inlet 42. In one example, the lever 170 may be coupled to a shaft 172 positioned near the nozzle inlet 42 such that when the lever 170 is rotated, the agitator block 106 rotates about the longitudinal axis of the nozzle inlet 42 and may be moved in an agitating position ( Figure 6 ) and self-cleaning position ( Figure 7 ). It will be appreciated that the lever 170 and / or the agitator block 106 may be spring biased, magnetically biased, etc., to maintain the agitator block 106 in an agitating position and / or a self-cleaning position, as discussed in more detail herein. Although illustrated as a lever 170 connected to an axis 172, it is within the scope of the present disclosure that the agitator block 106 is moved using any suitable configuration (such as various switches, levers, knobs, wheels, etc.). In addition, it is within the scope of the present disclosure that the agitator block 106 is flipped between at least the first side and the second side without the use of a lever, etc. For example, the agitator block 106 may be removed and reinserted into the cleaning tool 10 at another position, and may be snapped or otherwise locked in place.

[0038] Still see Figure 6 , Figure 7 and Fig.11 As previously described, the agitator block 106 can be biased to one of the agitation position and the self-cleaning position. In one example, the torsion spring can bias the agitator block 106 rearward (e.g., the agitation position) and / or forward (e.g., the self-cleaning position). Optionally, the operating mode of the cleaning tool 10 can be changed based on the position of the agitator block 106. For example, the controller 178 ( Figure 1 ) may receive input from the momentary switch 174 that the agitator block 106 is in the agitation position, and the controller 178 may allow the cleaning fluid to be dispensed at a first speed. Similarly, the controller 178 may receive input from the momentary switch 174 that the agitator block 106 is in the self-cleaning position, and the controller 178 may allow the cleaning fluid to be dispensed at a second speed different from the first speed. In another example, the controller may activate a graphic or indicia (e.g., on the cleaning tool body 26) based on the detected position of the agitator block 106 to indicate the cleaning position or mode of the suction nozzle 40.

[0039] As shown, the agitator block 106 includes a plurality of openings 180 extending from the first surface 160 to the second surface 164. In some examples, such as Figure 7 As shown, at least one of the plurality of openings 180 extends to a perimeter 184 or side edge of the agitator block 106, thereby forming a ventilation hole 182 leading to the suction nozzle inlet 42. When the agitator block 106 is in the self-cleaning position, the presence of the ventilation hole 182 in the agitator block 106 can improve suction by allowing ventilation airflow to enter the suction nozzle inlet 42. The ventilation airflow can increase the air velocity near the perimeter 184 of the suction nozzle 40, so that the airflow can continue to move through the suction channel 50 under a sealed or partially sealed condition (e.g., in the self-cleaning position).

[0040] Based on the application of cleaning tool 10, agitator (such as nub 168) can comprise any pattern, shape and material type.Nub 168 can be constructed by elastomer, nylon or any other suitable material.In another example, agitator block 106 agitator can comprise a plurality of bristles, and these a plurality of bristles can be made by any suitable synthetic or natural fiber.In either case, nub 168 or bristles can be arranged into a plurality of clusters or continuous strips.In addition, nub 168 or bristles can be arranged into single row or multiple rows, and optionally these rows are staggered or offset so that the density of nub 168 or bristles is maximized.It is also within the scope of the present disclosure that agitator block 106 can be removed so that various agitator blocks 106 can be interchangeably mounted to the suction nozzle 40 of cleaning tool 10.

[0041] like Figure 6 As shown, in the agitation position, the agitator block 106 is disposed behind the suction nozzle inlet 42. In the agitation position, the small block 168 extends toward the surface to be cleaned and thus agitates the surface and loosens debris to facilitate introduction of the debris into the suction nozzle inlet 42. Although illustrated as being behind the suction nozzle 40 in the agitation position, the agitator block 106 is not limited to such a position. For example, the agitator block 106 can be disposed in front of the suction nozzle inlet 42 in the agitation position.

[0042] like Figure 7 and Figure 8 As shown, in the self-cleaning position, the agitator block 106 covers or partially covers the suction nozzle inlet 42. Therefore, the agitator block 106 can be at least partially disposed within the suction nozzle inlet 42 in the self-cleaning position. In the self-cleaning position, the nub 168 extends from the agitator block 106 toward the at least one fluid dispenser 94. In this way, the nub 168 is disposed within the suction channel 50 adjacent to the plurality of outlets 98. During the self-cleaning process, air can be drawn through the opening 180 in the agitator block 106 to loosen debris from the nub 168, which will be described in further detail below.

[0043] See now Figures 9 to 11 , showing lens 46 in more detail. In some aspects, lens 46 can be in at least a first position ( Fig.10 ) and the second position ( Fig. 9). In some aspects, in the second position, the lens 46 can extend outward relative to the first position. In the first position, the lens 46 can define a suction channel depth of about 1 mm to about 3 mm or any / all ranges therebetween. In the second position, the lens 46 can define a suction channel depth greater than the depth in the first position, such as a depth of about 3 mm to about 7 mm or any / all ranges therebetween. Thus, when the lens 46 is in the second position, the volume of the suction channel 50 increases relative to the volume of the suction channel 50 when the lens is in the first position. In some aspects, the suction channel depth can be substantially constant or can vary along the length of the suction channel 50. In the first position ( Fig.10 ), the suction channel depth along at least a portion of the length of the suction channel 50 is less than that in the second position ( Fig. 9 ) of the suction channel depth. Thus, the first position can be referred to as a retracted position. In the retracted position, the suction channel 50 includes a tighter / more restricted air path that provides a higher air velocity, which is more suitable for extracting liquids and fine debris. When the lens 46 is in the second, extended position, a larger air passage is formed. Thus, extension of the lens 46 to the second or extended position allows "bulk" debris (which may include a mixture of liquids and solids of various sizes and densities) to be drawn into the suction channel 50 so that the canister 34 can capture the debris.

[0044] The lens 46 can be adjusted by linear translation or rotational translation (e.g., inward / outward tilt), but is not limited thereto. In some specific implementations, the lens 46 can be adjusted by pressing a button (e.g., a finger button) that is coupled to a torsion spring configured to move the lens 46 from a first position to a second position. Optionally, the lens 46 can be adjusted by pulling the lens 46 outward to the second position and pushing inward to return the lens 46 to the first position. In some aspects, a seal or gasket (e.g., an accordion gasket) is coupled to the nozzle 40 and is configured to maintain suction when the lens 46 is in the first position and the second position. In addition, in some examples, the lens 46 is configured to include a physical relationship (e.g., interlock, clamp, etc.) relative to the agitator block 106, so that the agitator block 106 can be deployed or adjusted only when the lens 46 is in a predetermined position (e.g., in an agitation position) and the suction channel 50 is narrowest (e.g., in the first position of the lens 46). Therefore, the lens 46 can be prevented from accidentally moving outward / forward.

[0045] See now Figure 6 , Fig. 9 and Fig.10, the cleaning tool 10 is illustrated in various exemplary agitation positions, wherein the agitator block 106 is disposed behind the suction nozzle inlet 42. Thus, the small pieces 168 extend from the first surface 160 toward the surface to be cleaned. Also in the agitation position, the agitator block 106 does not block the suction nozzle inlet 42. Thus, the cleaning fluid and entrained debris from the surface being cleaned can enter the suction channel 50 and travel through the suction path 30 to be separated and stored in the tank 34. In addition, since the agitator block 106 does not block the suction nozzle inlet 42, any cleaning fluid distributed from the fluid distributor 94 can flow outward from the suction nozzle 40 and contact the surface being cleaned. In some aspects, the cleaning fluid is pressurized and can be ejected from the outlet 98 in a downward direction.

[0046] See now Figure 7 and Figure 8 , shows the cleaning tool 10 in an exemplary self-cleaning position, wherein the agitator block 106 at least partially covers the suction nozzle inlet 42. In the self-cleaning position, the second surface 164 is exposed to the exterior of the cleaning tool, which is opposite to the agitation position in which the first surface 160 is exposed. Since the agitator or small block 168 is disposed on the first surface 160, which now faces the suction channel 50, the small block 168 is adjacent to the plurality of outlets 98 and extends toward the plurality of outlets. Therefore, the small block 168 is positioned to receive the cleaning fluid from the fluid distributor 94. As shown in FIG. Figure 8 As shown, the fluid distributor 94 is designed to limit the deflector portion 108 at each outlet 98. The deflector portion 108 is arranged at the outlet 98 (which can be the end of the fluid distribution path) to facilitate the supplied cleaning fluid to be directed downward to the first surface 160, so as to effectively loosen the debris captured on / between the small pieces 168 and the first surface 160. Therefore, the cleaning tool 10 may include an integrated agitator cleaning system. When the cleaning tool 10 is operated in a self-cleaning mode (for example, when the agitator block 106 is in the self-cleaning position), the cleaning fluid distributed from the fluid distributor 94 does not usually leave the suction nozzle 40, because the air flow velocity from the suction path 30 is stronger than the force of the cleaning fluid spray. Therefore, the user can adjust, flip or turn the agitator block 106 to enter the self-cleaning position and activate the supply of the cleaning fluid so that the fluid discharges the debris from the small pieces 168. Because the suction source 22 is activated, when the air is extracted by the suction path 30, the discharged debris and fluid can be extracted by the suction path.

[0047] By way of non-limiting example, the cleaning tool 10 may be actuable between at least three different operating states: (1) a self-cleaning mode (an example of which is shown in FIG. Figure 7 ), wherein the agitator block 106 simultaneously blocks / seals the nozzle inlet 42; (2) a fine extraction agitation mode (an example of which is shown in Fig.10), wherein the agitator block 106 does not block / seal the nozzle inlet 42 and the agitator is extended toward the surface to be cleaned while the lens 46 is in the retracted / narrowest position; and (3) a coarse extraction agitation mode (an example of which is shown in Fig. 9 ), where the agitator block 106 does not block / seal the nozzle inlet 42 and the agitator is extended towards the surface to be cleaned while the lens 46 is in the extended position.

[0048] See again Figure 1 , the controller 178 is electrically connected to the recovery assembly 70 (including the suction source 22) and the fluid delivery system 74 via an electrical path. The controller 178 is configured to control the amount of suction generated by the suction source 22, the supply of liquid to the dispenser outlet 98 (e.g., via the pump 101), the activation of the fluid heater 100, etc. In some aspects, the spray trigger 82 ( Figure 4 ) is electrically connected to the controller 178 to control the liquid supply to the dispenser outlet 98. Alternatively, the spray trigger 82 can be connected to the valve to open / close the valve when the liquid pump (such as, for example, pump 101) is always on (e.g., always pumping fluid). It is within the scope of the present disclosure that the extraction cleaner 14 and / or the cleaning tool 10 include any suitable input controls for controlling the operation of the extraction cleaner 14 and / or the cleaning tool 10. For example, the input controls may include power buttons, cleaning fluid controls (e.g., spray trigger 82), agitator block controls and other various hardware of the extraction cleaner 14. The electrical path may be at least partially arranged on a printed circuit board assembly (PCBA). The controller 178 may include a processor, a memory and various control circuits. Instructions or routines may be stored in the memory and may be executed by the processor. The controller 178 is generally configured to collect inputs from various electronic components, process the inputs, and generate output responses to the collected inputs. The processor may include any type of processor capable of performing the functions described herein. The processor can be in the form of a dual-core processor, a multi-core or multi-threaded processor, a digital signal processor, a microcontroller, or any other processor or processing / control circuit having multiple processor cores or other independent processing units. The memory may include any type of volatile or non-volatile memory (e.g., RAM, ROM, PSRAM) or data storage device (e.g., hard drive, solid-state drive, etc.) capable of performing the functions described herein. In operation, the memory may store various data and software used during the operation of the extractor cleaner 14, such as operating systems, applications, programs, libraries, databases, and drivers. The memory may include a plurality of instructions that, when read by the processor, cause the processor to perform the functions described herein.

[0049] The cleaning tool 10 according to various aspects of the present disclosure provides multiple benefits. As described in detail herein, when the cleaning tool 10 is operated in the self-cleaning mode, the cleaning tool 10 may include an integrated agitator cleaning system. The integrated agitator cleaning system provides an easier / desirable process for cleaning hair, dirt and other debris from the agitator, because the user can avoid actively contacting the debris, but can rely on the self-cleaning mode. In addition, the cleaning tool 10 is configured to capture large debris, and preferably captures any liquid in the tank 34 of the cleaning tool 10, so that large debris and liquid are captured before traveling to the hose 18 and finally traveling to the recovery tank of the extraction cleaner 14. Larger debris may be stuck in the hose 18 and the recovery assembly 70, and therefore more difficult to remove than liquid and smaller debris. The larger debris captured may affect the performance of the extraction cleaner 14, but may also cause a foul smell when the debris rots. The larger debris is captured in the cleaning tool 10 to reduce the possibility of larger debris being captured in the hose 18 and the recovery assembly 70. In addition, if it is only to minimize cleaning, it is ideal to capture liquid in the cleaning tool 10. However, if some liquid does enter the hose 18 and / or the recovery assembly 70, it is easier to rinse these parts to avoid stains and odors, because the cleaning tool 10 can significantly reduce the amount of liquid that may enter these parts. Therefore, the construction of the cleaning tool 10 particularly suppresses the suction of large debris, and in some specific implementations, suppresses the various internal systems (e.g., recovery systems) of the liquid entering the extractor cleaner 14. Similarly, the construction of the cleaning tool 10 makes it easy to disinfect / clean the internal components and surfaces of the tool body 26. When the lens 46 is in the extended position, the cleaning tool 10 is also conducive to effectively cleaning coarse debris (e.g., pet vomit) from the surface. Therefore, it is possible to prevent users from contacting debris with their hands (e.g., such as when debris leaks through a paper towel during a traditional cleaning procedure). Advantageously, the cleaning tool 10 can be configured to be attached to various surface cleaning devices.
