[0023] refer to Figures 1 to 12 , reference numeral 10 generally designates a cleaning apparatus that includes a support or base housing 12, a suction assembly 14 operably coupled to the base housing 12, and a liquid delivery system 16 operably coupled to the base housing 12. A wand 18 is coupled to the base housing 12 and is in fluid communication with the suction assembly 14 and the liquid delivery system 16 via an attachment hose 20. A rotating scrubbing tool 22 is selectively coupled to the wand 18. The rotating scrubbing tool 22 includes a motor assembly 24, a support member 26, and a pad base 28. The support member 26 includes a connector 30 configured to couple to the wand 18 and a guide 32. The pad base 28 is operably coupled to the motor assembly 24 within an interior 100 of the guide 32 to drive rotation of the pad base 28. The pad base 28 defines an air outlet 34 and one or more liquid outlets 36 proximate a central rotational axis 38, and one or more fluid inlets 40 proximate an outer peripheral edge 42 of the pad base 28. Suction assembly 14 is configured to direct air through air outlet 34, across pad base 28 and through fluid inlet 40. Liquid dispensed from liquid delivery system 16 via liquid outlet 36 is directed by suction assembly 14 across pad base 28 and through fluid inlet 40 along with the air.

[0024] refer to Figure 1 and Figure 2 , the rotary scrubbing tool 22 can be selectively connected to a variety of cleaning devices 10. Each configuration of the cleaning device 10 generally includes a base housing 12 operably connected to a suction assembly 14 and a liquid delivery system 16. The suction assembly 14 and the liquid delivery system 16 can be collectively referred to as a fluid guiding system or a fluid delivery and recovery system. The fluid guiding system is configured to guide fluid in multiple directions, and is also configured to guide both liquid and air. The suction assembly 14 is configured to suck fluid into the base housing 12, and the liquid delivery system 16 is configured to guide liquid out of the base housing 12.

[0025] The suction assembly 14 generally includes a suction source (such as a motorized fan assembly) configured to draw fluids (such as air and liquids) into a recovery tank or container 50 operably coupled to the base housing 12. The suction assembly 14 generally operates to create a suction or vacuum effect to draw fluids and / or debris materials from the surface to be cleaned into the recovery container 50. The recovery container 50 can be selectively removed from the base housing 12 to dispose of the liquid and debris materials captured in the recovery container 50 by the suction assembly 14. The cleaning device 10 may include a separator for separating the liquid and debris materials from the airflow for collection.

[0026] Liquid delivery system 16 is configured to guide liquid from supply tank 52 and guide it out of base housing 12 for cleaning process. Cleaning equipment 10 includes supply tank 52 operably connected to base housing 12, and the supply tank is configured to hold and store liquid. The liquid can be water, cleaning solution or a combination thereof. For example, many household extraction cleaning tasks can be performed together with or in combination with liquid cleaning solutions containing surfactants, stabilizers, spices and / or other active and inactive ingredients using water. Liquid delivery system 16 also includes pumps, valves and / or other similar features for guiding liquid out of supply tank 52 and thus guiding out of cleaning equipment 10. Cleaning equipment 10 may optionally include a heater for heating or warming the distributed liquid.

[0027] Still refer to Figure 1 and Figure 2 , the cleaning device 10 may be an extraction cleaner commonly used to clean rugs, carpets, curtains, and upholstered surfaces. The cleaning device 10 may be used with tools or accessories that can clean similar surfaces and / or hard surfaces. The cleaning device 10 may be configured as a portable cleaning device 10, such as Figure 1 The portable cleaning device 10 is generally small and lightweight, and typically includes a handle 54 by which a user may pick up and carry the portable cleaning device 10 .

[0028] like Figure 2 As shown, the cleaning device 10 may additionally or alternatively be configured as an upright cleaning device 10. The upright cleaning device 10 includes an elongated handle 56 that a user may use to move and maneuver the upright cleaning device 10 along an underlying surface. Typically, the user maneuvers the upright cleaning device 10 via wheels 58 operably coupled to the base housing 12 to roll the upright cleaning device 10 over the underlying surface. Typically, the upright cleaning device 10 has a drive assembly for assisting the user in maneuvering the upright cleaning device 10. The upright cleaning device 10 is typically larger and heavier than a portable cleaning device 10, and has a lower surface proximate the wheels 58 that engages the underlying floor surface.

[0029] Portable cleaning equipment 10 and upright cleaning equipment 10 can perform the same function, perform different functions, perform overlapping functions, etc. The function of cleaning equipment 10 can be performed separately from tool or attachment, or can be utilized by tool or attachment. For example, cleaning equipment 10 can be operable to deliver room temperature water, hot water, chemical cleaning solution or their combination to tool and / or surface to be cleaned with cleaning equipment 10. Similarly, cleaning equipment 10 can be configured to generate vacuum effect to capture fluid and debris materials at the surface being cleaned by cleaning equipment 10 and / or tool. In this way, the surface being cleaned by cleaning equipment 10 can be the same or different with the surface to be cleaned by tool. In addition, cleaning equipment 10 may include the electric wire that engages a power socket to receive electric power, or may include the battery that is used to power cleaning equipment 10 and / or tool.

[0030] Still refer to Figure 1 and Figure 2 as well as Figure 3 , the cleaning device 10 (including any configuration of a portable or upright cleaning device 10) utilizes a fluid directing system with each of a suction assembly 14 and a liquid delivery system 16. When not used with a tool, the cleaning device 10 uses the suction assembly 14 and the liquid delivery system 16 to perform various cleaning functions. The cleaning device 10 can also be used with a tool that is selectively coupled to the cleaning device 10 via an accessory hose 20. The tool, such as the rotary scrubbing tool 22, is typically manually maneuverable by a user relative to the cleaning device 10.

[0031] The tool or attachment disclosed herein is configured as a rotary scrubbing tool 22. The rotary scrubbing tool 22 is configured to utilize various features and functions of the cleaning device 10, including the suction assembly 14 and the liquid delivery system 16. When the rotary scrubbing tool 22 is used with the cleaning device 10, the suction assembly 14 and the liquid delivery system 16 are used with the rotary scrubbing tool 22 and are separate from the functions of the cleaning device 10. Therefore, the cleaning device 10 may include a valve or similar feature that directs fluid to and from the rotary scrubbing tool 22 when the rotary scrubbing tool 22 is not coupled to the base housing 12, as well as directing fluid to and from other locations of the cleaning device 10.

[0032] The accessory hose 20 and the wand 18 provide fluid communication between the fluid directing system of the cleaning device 10 and the rotary scrubbing tool 22. The wand 18 is coupled to the distal end of the accessory hose 20 and is configured to be inserted into the connector 30 of the support member 26 to couple the rotary scrubbing tool 22 to the wand 18. The specific alignment between the rotary scrubbing tool 22 and the wand 18 facilitates providing fluid communication between the rotary scrubbing tool 22 and the suction assembly 14 and between the rotary scrubbing tool 22 and the liquid delivery system 16.

[0033] The wand 18 is configured to provide a gripping position for the user. The user can grip the wand 18 and / or the connector 30 to move the rotary scrubbing tool 22 relative to the surface to be cleaned. It is also contemplated that the user can grip the rotary scrubbing tool 22 and / or an auxiliary handle of the rotary scrubbing tool 22 without departing from the teachings herein. The user can move the rotary scrubbing tool 22 over the surface to be cleaned to collect, capture, or otherwise engage debris material from the surface to be cleaned and provide a cleaning function. Based on the configuration of the rotary scrubbing tool 22, the surface to be cleaned can be a horizontal surface (including a ceiling) or a non-horizontal surface.

[0034] Still refer to Figure 3 as well as Figure 4 and Figure 5 , the wand 18 includes a conduit 76 for delivering liquid from the liquid delivery system 16, which is selectively opened and closed via a valve 78. The valve 78 is operably coupled to a biasing member 80 (illustrated as a coil spring). The biasing member 80 is configured to bias the valve 78 to a closed state, which prevents liquid from flowing to the rotating scrubbing tool 22. The valve 78 is configured to be actuated when a force is applied to an actuator (such as a trigger or button 82 on the wand 18). Adjustment of the button 82 into the wand 18 is configured to actuate the valve 78 to an open state, thereby providing fluid communication with the rotating scrubbing tool 22.

[0035] Thus, the liquid delivered to the rotary scrubbing tool 22 is controlled by the user. The user can press the button 82 to actuate the valve 78 and intermittently open the fluid communication as needed, or maintain the fluid communication open and continuously provide liquid to the rotary scrubbing tool 22. In some configurations, the liquid delivery through the rotary scrubbing tool 22 can be controlled by an actuator and fluid flow control system (e.g., valve) carried by the rotary scrubbing tool 22. In additional or alternative configurations, the liquid delivery through the rotary scrubbing tool 22 can be controlled by an electronically controlled fluid flow system that delivers liquid through the rotary scrubbing tool 22 based on mode selection (e.g., spot cleaning mode) and / or based on sensor information (e.g., sensor information based on the degree of contamination of the surface being cleaned).

[0036] The rotary scrubbing tool 22 includes a support member 26 with a connector 30 and a guide 32. The connector 30 is configured to receive and couple to the wand 18. The wand 18 includes a stopper 88 configured to be disposed within a hole 90 defined by the connector 30 to selectively couple the rotary scrubbing tool 22 to the wand 18. The wand 18 is partially inserted into the support member 26 and the stopper 88 is moved into the hole 90. The stopper 88 can be moved or adjusted to allow the rotary scrubbing tool 22 to be disengaged from the wand 18, which facilitates cleaning the rotary scrubbing tool 22 or selectively coupling different accessories or tools to the wand 18.

[0037] The connector 30 includes two passages 92, 94 for receiving portions of the rod 18. The first passage 92 receives the distal end of the rod 18 and includes a stopper 96 for limiting the insertion of the rod 18 into the first passage 92. The first passage 92 is in fluid communication with the interior 100 of the support member 26 and the rod 18 to form a portion of a fluid flow path 102 as described herein. The second passage 94 receives the liquid delivery outlet 104 of the conduit 76. The liquid dispensed from the liquid delivery system 16 is configured to flow through the conduit 76 and into the second passage 94 to be delivered to the pad base 28, as described herein. Therefore, the conduit 76 and the second passage 94 form a portion of the liquid flow path 106.

[0038] Still refer to Figures 3 to 5 , the support member 26 includes a guide 32 coupled to the connector 30. The guide 32 is formed in a generally hemispherical shape, thereby defining a hollow interior 100 for receiving the other parts of the rotating scrubbing tool 22. Each of the first passage 92 and the second passage 94 is in fluid communication with the interior 100 of the guide 32. The guide 32 includes a first end opening 110 and a second end opening 112, each of which is a central opening that is generally coaxial with each other. Based on the shape of the guide 32, the first end opening 110 is smaller than the second end opening 112.

[0039] The rotary scrubbing tool 22 includes a motor assembly 24 that extends through the first end opening 110 and into the interior 100 of the guide 32. The motor assembly 24 includes a motor, gears, and a drive connection 116. The motor assembly 24 is configured to drive the rotational movement of various features of the rotary scrubbing tool 22 about the rotational axis 38 of the rotary scrubbing tool 22.

[0040] Still refer to Figures 3 to 5 , the motor assembly 24 is partially disposed within the interior 100 of the guide 32 and partially disposed within the interior 118 of the motor housing 120. The motor housing 120 includes two housing portions 122, 124 coupled together around the motor assembly 24. In the example shown, the motor housing 120 includes a snap feature 126 that is configured to snap engage with the guide 32 adjacent the first end opening 110. The snap feature 126 is configured to extend through the first end opening 110 and engage a mating feature on the inner surface of the guide 32 to couple the motor housing 120 to the guide 32. The snap feature 126 can be an elastically deformable component, allowing a user to press the snap feature 126 to disengage the snap feature 126 from the guide 32 and ultimately disengage the motor housing 120.

[0041] In the example shown, the motor housing 120 defines an aperture 128 configured to receive a power switch 130. The power switch 130 is in electrical communication with the motor assembly 24. In this manner, a user can interact with the power switch 130 to control the motor assembly 24. In various examples, the power switch 130 can be used to activate and deactivate the motor assembly 24. In additional or alternative examples, the power switch 130 can also be used to adjust various settings of the motor assembly 24, such as speed. Although the power switch 130 is illustrated as being carried by the rotary scrubbing tool 22, in some configurations, the power switch 130 can be carried by the cleaning device 10, and the accessory hose 20 can carry electrical wiring that electrically couples the rotary scrubbing tool 22 to the cleaning device 10.

[0042] Still refer to Figures 3 to 5 , the motor housing 120 defines a vent 138 to provide fluid communication between the interior 118 of the motor housing 120 and an area outside the motor housing 120 (i.e., an area surrounding the rotary scrubbing tool 22). The vent 138, the interior 118 of the motor housing 120, and the interior 100 of the guide 32 are in fluid communication with each other and define a portion of an airflow path 140 through the rotary scrubbing tool 22. The vent 138 is defined on an end of the motor housing 120 and may be defined in additional or alternative locations on the motor housing 120 or the support member 26 without departing from the teachings herein.

[0043] Still refer to Figure 4 and Figure 5 as well as Figure 6 , the rotary scrubbing tool 22 includes a connecting hub 144 disposed within the interior 100 of the guide 32. The connecting hub 144 is coupled to the drive connection 116 of the motor assembly 24 and the pad base 28. Typically, the connecting hub 144 is disposed within or extends into a central opening of the pad base 28 that forms the air outlet 34. The connecting hub 144 defines an air flow channel 146 that fluidly couples the interior 100 of the guide 32 and the interior 118 of the motor housing 120 with a space adjacent to a cleaning or outer surface 150 of the pad base 28 on an opposite side of the pad base 28. The air flow channel 146 is aligned with the central opening of the pad base 28 to form the air outlet 34. Based on the configuration of the pad base 28 and the connecting hub 144, the air outlet 34 can be a single outlet or configured as a plurality of outlets. The connecting hub 144 is operable to direct air through the pad base 28 for use in the cleaning process.

[0044] The rotary scrubbing tool 22 includes components for directing liquid to the pad base 28 for use in the cleaning process. For example, a fluid ring 152 is disposed within the interior 100 of the guide 32 and is coupled to the guide 32 proximate the first end opening 110. The fluid ring 152 includes a liquid inlet 154 that extends at least partially into the second passage 94 of the connector 30. The liquid inlet 154 is configured to receive liquid from the wand 18 and direct the liquid to the pad base 28. The fluid ring 152 is generally formed in an annular or ring shape that extends around the motor assembly 24 and the connecting hub 144.

[0045] The liquid inlet 154 of the fluid ring 152 extends through a sealing feature 156 and a seal retainer 158 disposed between the fluid ring 152 and the pad base 28. The sealing feature 156 defines an annular or ring shape with a central opening for the motor assembly 24 and the connecting hub 144. The sealing feature 156 abuts the fluid ring 152 and extends adjacent to or adjacent to the pad base 28. The sealing feature 156 has an abutment portion 160 and obtuse sidewalls 162, 164 extending in opposite directions from the abutment portion 160. The sealing feature 156 provides a substantially sealed space or sealed portion of the liquid flow path 106 between the fluid ring 152 and the pad base 28 for directing liquid from the liquid inlet 154 to the pad base 28. This sealed space facilitates containing liquid in the rotary scrubbing tool 22 in the liquid flow path 106.

[0046] The seal retainer 158 is disposed adjacent to the abutment 160 of the seal feature 156 between the sidewalls 162, 164. The seal retainer 158 can be configured to assist in retaining the fluid ring 152 and the seal feature 156 in position relative to each other. In addition, the liquid inlet 154 of the fluid ring 152 extends through the seal retainer 158.

[0047] Still refer to Figures 4 to 6, the rotary scrubbing tool 22 includes a pad base 28 that is coupled to the connecting hub 144 and extends through the second end opening 112 of the guide 32. The pad base 28 includes a support plate 170 and a surface treatment element 172, such as a scrubber pad 172. The surface treatment element 172 may include any suitable material or combination of materials for treating a surface, non-limiting examples of which include scrubber pads, absorbent materials, polishing materials, agitating elements, bristles, abrasive materials, microfibers, etc. The support plate 170 is operably coupled to the connecting hub 144 to assist in transferring the rotational movement to the scrubber pad 172. The support plate 170 has an inner surface 174 oriented toward the interior 100 of the guide 32 and an outer surface 176 to which the scrubber pad 172 is coupled. Typically, the scrubber pad 172 is constructed of a closed cell foam material. The closed cell foam material may be advantageous in softening when wet and not retaining large amounts of liquid. The scrubber pad 172 may be a single component or multiple components connected to the support plate 170 in a particular arrangement.

[0048] In the example shown, the pad base 28 defines an air outlet 34 at or adjacent the axis of rotation 38. The pad base 28 defines a plurality of fluid flow channels 178 extending from the central air outlet 34 toward or to the peripheral edge 42 of the scrubber pad 172. In this manner, the fluid flow channels 178 span the scrubber pad 172 and extend radially outward of the air outlet 34. In addition, the fluid flow channels 178 may extend the entire depth of the scrubber pad 172, extending from the support plate 170 and through the outer surface 150 of the scrubber pad 172. However, shallower fluid flow channels 178 may be utilized without departing from the teachings herein. Typically, the fluid flow channels 178 define an arc that curves in the same direction. The curved and arcuate configuration of the fluid flow channels 178 may facilitate directing fluid along the fluid flow channels 178 and toward the peripheral edge 42 as the pad base 28 rotates.

[0049] The pad base 28 defines a fluid inlet 40 adjacent to the peripheral edge 42 of the pad base 28 and at the distal end 180 of each flow channel 178. The fluid inlet 40 may be defined by the support plate 170, the scrubber pad 172, or both, depending on the configuration of the pad base 28. The air outlet 34 and the liquid outlet 36 are defined at or near the proximal end 182 of the fluid flow channel 178, and the fluid inlet 40 is defined at or near the opposite distal end 180 of the fluid flow channel 178. The liquid outlet 36 is defined adjacent to the air outlet 34 and is generally arranged around the air outlet 34, which allows air to flow through the liquid outlet 36 to direct the dispensed liquid across the pad base 28, as described herein. In the illustrated configuration, each flow channel 178 is aligned with one liquid outlet 36 and one fluid inlet 40. One or both of the liquid outlet 36 and the fluid inlet 40 may be defined within the fluid flow channel 178, respectively. It is also contemplated that more than one liquid outlet 36 and / or more than one fluid inlet 40 may be defined in each fluid flow channel 178. Additionally or alternatively, one or both of the liquid outlet 36 and the fluid inlet 40 may be defined adjacent or proximate to the end 180, 182 of the fluid flow channel 178.

[0050] Still refer to Figures 4 to 6 As shown, the support plate 170 defines an elongated protrusion 188 that extends into the fluid flow channels 178. The elongated protrusion 188 extends along most or all of each flow channel 178. Figure 6 As shown, the elongated protrusion 188 also defines the liquid outlet 36. Additionally, the elongated protrusion 188 defines holes 190 spaced apart along its length. Internal bristles 192 are disposed in the holes 190 and are coupled to the support plate 170. Thus, each flow channel 178 includes internal bristles 192 spaced apart along its length. In this manner, each flow channel 178 includes a plurality of internal bristles 192 arranged in a side-by-side configuration from the proximal end 182 to the distal end 180.

[0051] The inner bristles 192 generally extend beyond the outer surface 150 of the pad base 28 for engaging the surface to be cleaned. The inner bristles 192 may be constructed of any feasible material, such as foam, rubber, nylon, polymers, etc., which may be selected based on the type of surface to be cleaned. In addition, when the rotary scrubbing tool 22 is used against the surface to be cleaned, the inner bristles 192 may be able to elastically deform to provide a scrubbing or cleaning function. The pad base 28 may also be used without the inner bristles 192 without departing from the teachings herein.

[0052] Still refer to Figures 4 to 6, the pad base 28 is a rotating feature of the rotary scrubbing tool 22 for providing a cleaning function. Therefore, the motor assembly 24 drives the connecting hub 144 and the pad base 28 (including the support plate 170, the scrubber pad 172 and the internal bristles 192) to rotate.

[0053] The rotary scrubbing tool 22 may also include a peripheral gasket or peripheral seal 198. The peripheral seal 198 extends proximate the peripheral edge 42 of the pad base 28, generally surrounding or encircling the pad base 28. The peripheral seal 198 is coupled to the guide 32 and therefore does not rotate with the pad base 28. The peripheral seal 198 includes a receiving portion 200 that is configured to engage an edge 202 of the guide 32 that defines the second end opening 112. Typically, the peripheral seal 198 is constructed of a resilient material such as rubber or silicone. In such examples, the receiving portion 200 is configured to elastically deform to receive and retain the edge 202 of the guide 32.

[0054] exist Figures 4 to 6 In the illustrated configuration, the peripheral seal 198 is illustrated as a scrubber skirt 206. The scrubber skirt 206 includes outer bristles 208 arranged in a plurality of concentric rings. The outer bristles 208 are typically constructed of an elastomeric material and are configured to act as a seal around the pad base 28. The outer bristles 208 are typically narrow and closely spaced together to form a seal. Additionally, as shown, the ring of outer bristles 208 closest to the scrubber pad 172 is shorter than the remaining rings of outer bristles 208 to assist in forming a seal on uneven surfaces.

[0055] refer to Figures 7 to 9 The pad base 28 and the peripheral seal 198 may have different configurations, which may be determined by the type of surface to be cleaned, the type of debris material to be cleaned, or the cleaning process. For example, the rotary scrubbing tool 22 can be used on a variety of hard surfaces, such as floors, wood, tile, glass, etc. Figures 7 to 9 In the example shown, the scrubber pad 172 is a single component that defines a fluid flow channel 178, wherein the fluid flow channel 178 extends from the outer surface 150 of the scrubber pad 172 and toward the support plate 170 for a portion of the depth of the scrubber pad 172. Thus, the fluid flow channel 178 is shallow and does not extend to the support plate 170. Furthermore, in such a configuration, the inner bristles 192 may be omitted.

[0056] The support plate 170 can define an outlet protrusion 212 that extends partially through the scrubber pad 172. In various examples, the outlet protrusion 212 defines the liquid outlet 36 and may not be elongated to extend along the fluid flow channel 178. The outlet protrusion 212 defining the liquid outlet 36 can assist in directing liquid into the shallower fluid flow channel 178.

[0057] Still refer to Figures 7 to 9 , the peripheral seal 198 is configured as a ribbed scrubber 216. The ribbed scrubber 216 is constructed of an elastic material and is configured to deform in response to a force against the surface being cleaned. The ribbed scrubber 216 is configured to extend partially into the interior 100 of the guide 32. In such an example, the ribbed scrubber 216 can define an annular groove 218 oriented toward the support plate 170. The support plate 170 is configured to rotate within the annular groove 218. This configuration can provide an increased seal along the edge of the support plate 170.

[0058] The contact surface 220 is generally curved, folded, or arcuate, and is configured to deform when pressed against the surface being cleaned to provide a seal around the pad base 28. The contact surface 220 may be generally aligned with the outer surface 150 of the scrubber pad 172. The contact surface 220 of the ribbed scrubber 216 defines ribs 222 that are spaced apart from each other. The ribs 222 may be protruding or recessed relative to the contact surface 220, thereby forming notched ribs 222 or grooves. The ribs 222 are generally integrally formed with the ribbed scrubber 216 and are radially oriented around the pad base 28. The ribbed scrubber 216 is configured to act as a loose seal around the pad base 28, allowing airflow due to the configuration of the ribs 222. In addition, the ribbed scrubber 216 may be advantageous in providing a squeegee-like effect using the ribs 222. Therefore, the ribbed scrubber 216 may be advantageous in cleaning the glass surface.

[0059] refer to Fig.10 and Fig.11 In an additional or alternative configuration, the peripheral seal 198 may be configured as a smoothing wiper 226, which may be substantially similar to Figures 7 to 9 In contrast, Fig.10 and Fig.11 The smooth scrubber 226 shown has a smooth contact surface 220 with the ribs 222 omitted. The smooth contact surface 220 generally defines an arc or bend, fold or curved shape that is configured to deform against the surface being cleaned to maximize the surface area of ​​the contact surface 220 that engages the surface being cleaned. The smooth scrubber 226 can provide a cleaning function with an increased seal around the pad base 28. Therefore, the smooth scrubber 226 can facilitate cleaning more vertical or ceiling-like surfaces.

[0060] refer to Fig.12, the scrubber pad 172 may have an additional or alternative configuration in which the fluid flow channel 178 is omitted. In such examples, the scrubber pad 172 defines a plurality of holes 230 in a selected pattern across the scrubber pad 172. The holes 230 extend from the support plate 170 through the scrubber pad 172 and through the outer surface 150. The support plate 170 defines a coupling protrusion 232 extending into each of the holes 230. Additionally, the pad base 28 includes inner bristles 192 coupled to the coupling protrusions 232 and extending through the holes 230. The inner bristles 192 extend beyond the outer surface 150 of the scrubber pad 172.

[0061] Generally, the inner bristles 192 are arranged to form a surface flow path 234 across the outer surface 150 of the pad base 28. The inner bristles 192 are arranged in a side-by-side configuration in an arcuate or curved pattern, similar to Figure 6 The pattern of the inner bristles 192 forms a surface flow path 234 between the arcuate shapes formed by the inner bristles 192 to direct the fluid across the scrubber pad 172 and to the fluid inlet 40. Typically, the liquid outlet 36 and the fluid inlet 40 are arranged at opposite ends of the surface flow path 234 formed by the inner bristles 192.

[0062] refer to Figures 1 to 12 , different configurations of the pad base 28 and the peripheral seal 198 can be used in any combination. Therefore, any configuration of the pad base 28 can be used with any configuration of the peripheral seal 198. In addition, the peripheral seal 198 can be interchangeable to provide different cleaning and sealing functions.

[0063] In operation, the user is configured to insert the rod 18 into the connector 30 to connect the rotary scrubbing tool 22 to the cleaning device 10. The user can then activate the rotary scrubbing tool 22 via the power switch 130 and subsequently activate the motor assembly 24. The motor assembly 24 is configured to drive the rotational movement of the pad base 28 around the rotation axis 38. In this way, the pad base 28 with the surface treatment element 172 and the internal bristles 192 can provide a rotary cleaning function on the surface to be cleaned, while the peripheral seal 198 remains stationary to provide an external seal. In addition, the pad base 28 can support any type of cleaning implementation, including agitators, bristles, polishing pads, cleaning materials, absorbent materials, abrasive materials, combinations, etc., to provide additional or alternative cleaning functions.

[0064] The rotary scrubbing tool 22 is configured to use both air and liquid for the cleaning process and for minimizing wet spots and excess liquid. The rotary scrubbing tool 22 can utilize airflow to disperse and control the dispensed liquid. By pressing the button 82, liquid from the liquid delivery system 16 is introduced into the rotary scrubbing tool 22 via the opening of the valve 78. The liquid flows through the wand 18 and into the connector 30. The liquid then flows through the fluid ring 152 and through the liquid outlet 36. Thus, the liquid flow path 106 is defined from the liquid delivery system 16 through the attachment hose 20, through the wand 18, through the support member 26 and through the liquid outlet 36.

[0065] Rotation of the pad base 28 allows liquid to be dispensed from one liquid inlet 154 and through the plurality of liquid outlets 36. In addition, the support plate 170 may define a recessed area 238 in the inner surface 174 to capture liquid and direct it to the liquid outlets 36. Based on the configuration of the pad base 28, the liquid is dispensed from the liquid outlets 36 proximate the rotation axis 38 and into the fluid flow channel 178 or the surface flow path 234. The liquid is dispensed onto the surface to be cleaned for use in the cleaning process.

[0066] The liquid delivery system 16 is configured to operate with the suction assembly 14. The suction assembly 14 provides a vacuum effect to draw liquid away from the surface being cleaned. This vacuum effect is generated when the outer surface 150 of the surface treatment element 172 engages the surface being cleaned, thereby forming a fluid flow path 102 through or across the pad base 28. Once the rotating scrubbing tool 22 engages the surface to be cleaned, air is drawn through the vent 138 of the motor housing 120, through the interior 100 of the guide 32, through the connecting hub 144 and through the air outlet 34. Therefore, the air flow path 140 is defined from the vent 138 through the guide 32 and across the pad base 28.

[0067] Due to the vacuum effect, air flowing through the air outlet 34 is drawn through the fluid flow channel 178 or the surface flow path 234 and toward the fluid inlet 40 at the peripheral edge 42. As air is drawn across the pad base 28, the air is drawn through the liquid outlet 36. Thus, as air is drawn across the liquid outlet 36, the air pulls the dispensed liquid across the pad base 28 toward the peripheral edge 42. In this way, the airflow generated by the suction assembly 14 assists in dispersing the liquid for the cleaning process, which also assists in minimizing wet spots from the dispensed liquid.

[0068] The air and liquid flow together from the central rotational axis 38 along the combined fluid flow path 102 and through the fluid inlet 40 at the peripheral edge 42. Thus, the fluid flow path 102 directs the air and liquid outwardly and across the pad base 28. In the example with the inner bristles 192, the fluid is directed around or through the inner bristles 192 to the fluid inlet 40. The air and liquid are then drawn into the interior 100 of the guide 32, through the connector 30, through the wand 18 and to the cleaning device 10. Overall, the air and liquid exit the rotating scrubbing tool 22 at a central location of the pad base 28 and disperse radially outward to the peripheral edge 42.

[0069] The airflow is configured to direct the liquid across the pad base 28 to increase the efficiency of the rotary scrubbing tool 22 and to more evenly distribute the liquid used in the cleaning process, thereby reducing wet spots and / or over-wetting of the surface. The liquid is configured to be extracted as the liquid is distributed across the pad base 28. In addition, the airflow and the peripheral seal 198 can reduce or eliminate liquid dripping from the rotary scrubbing tool 22. The cleaning process can generally be contained within the peripheral seal 198. In this way, the rotary scrubbing tool 22 can be utilized on non-horizontal surfaces (e.g., walls and windows) and horizontal surfaces (including ceilings) with minimal liquid dripping outside the rotary scrubbing tool 22.

[0070] In various aspects, to provide a greater suction effect for the cleaning process, the user can cover the vent 138 to reduce or prevent airflow into the rotary scrubbing tool 22. This increase in suction effect can be beneficial to provide a more rigorous cleaning process or function to the surface to be cleaned. This suction effect can also assist in collecting the dispensed liquid or liquid debris via the suction assembly 14. Although the vent 138 is illustrated as open unless covered by the user's hand, in some configurations, a damping system can be provided to selectively close the vent 138, which can be activated by the user or automatically based on the cleaning mode.

[0071] The use of the present device can provide a variety of advantages. For example, the rotary scrubbing tool 22 can utilize the liquid distributed from the cleaning device 10 for the cleaning process, and provide a vacuum effect for sucking the distributed liquid into the cleaning device 10, thereby providing fluid delivery and extraction using a single tool. In addition, the use of airflow is configured to disperse and control the liquid across the pad base 28 to more evenly distribute the liquid used for the cleaning process. Additionally, the rotary scrubbing tool 22 may include a peripheral seal 198, which is configured to provide an external seal around the pad base 28 to assist in capturing and retaining the distributed liquid. Moreover, the configuration of the rotary scrubber pad 172 with air-guided liquid and peripheral seal 198 provides a more closed or sealed assembly, so that the rotary scrubbing tool 22 can be utilized on more vertical surfaces (e.g., walls, windows, etc.) or ceiling surfaces. Additional benefits and advantages can be achieved and / or reached.
