[0020] Before describing any specific embodiments of the present disclosure in detail, it should be understood that the present disclosure is not limited to its application in the construction details and component arrangements described in the following description or shown in the drawings. The exemplary embodiments of the present disclosure can be implemented or realized in various ways. DETAILED DESCRIPTION

[0021] Figure 1 A surface cleaner 10 is shown that includes a base 12 and a body 14 pivotally coupled to the base 12. The body 14 is in an upright storage position ( Figure 1 ) and a tilted operating position relative to the base 12. The surface cleaner 10 further includes a vacuum source 18 operable to generate a vacuum from the suction inlet 66 ( Figure 6) to a suction airflow to a debris collector 22, which is in fluid communication with the vacuum source 18. In the illustrated embodiment, the surface cleaner 10 includes a supply tank 26 to store the cleaning fluid. In other embodiments, the surface cleaner 10 may be a vacuum cleaner that does not include a supply tank and does not spray fluid onto the surface. In such embodiments, the debris collector 22 may include a cyclone separator.

[0022] The handle 30 extends from the body 14 to allow the operator to move the surface cleaner 10 along the surface to be cleaned. The handle 30 includes a grip 34 and a user interface 38 adjacent to the grip 34. When operating the surface cleaner 10, the grip 34 can be grasped by the user, and the user interface 38 controls the vacuum source 18 and can control the flow of cleaning liquid from the supply tank 26 or other features of the cleaner. The user interface 38 can be set at another location on the cleaner. In the illustrated embodiment, a battery 42 is removably coupled to the surface cleaner 10 to power the surface cleaner 10 (e.g., the vacuum source 18 and the brush roll motor). The battery 42 of the illustrated embodiment is a rechargeable lithium-ion battery. In other embodiments, electricity is supplied to the cleaner via a power cord connected to the mains.

[0023] Reference Figure 1-6 , the base 12 includes a rearward end 46, a forward end 50 opposite the rearward end 46, a first side 54 extending between the rearward end 46 and the forward end 50, and a second side 58 opposite the first side 54. The base 12 includes wheels 62 to facilitate movement of the base 12 over a surface, and the base 12 includes a suction inlet 66 in fluid communication with the vacuum source 18 and the debris collector 22. A brush roll 70 is removably coupled to the base 12, and when coupled to the base 12, the brush roll 70 can rotate about a brush roll axis A1, which extends between the first side 54 and the second side 58 of the base 12. The base 12 further includes a latch 74 that selectively secures the brush roll 70 to the base 12, and a brush roll housing 82 that selectively couples to the base 12 to cover a portion of the brush roll 70. The base 12 further includes a fluid dispenser configured to deliver a fluid to a surface to be cleaned. In the illustrated embodiment, the fluid dispenser includes a plurality of dispensers 78 adjacent the suction inlet 66 and the brush roll 70. The dispensers 78 are in fluid communication with the supply tank 26 to selectively apply cleaning fluid to the brush roll 70 and wet the brush roll 70.

[0024] Continue to refer to Figure 2-6, the base 12 includes a drive mechanism 86 that is operably coupled to the brush roll 70 when the brush roll 70 is coupled to the base 12. The drive mechanism 86 includes an output end 90 to drive the brush roll 70 to rotate about the brush roll axis A1. In the illustrated embodiment, the output end 90 is adjacent to the second side 58 of the base 12. The drive mechanism 86 may include a brush roll motor 94 and a transmission 98 (schematically indicated at Figure 6 In some embodiments, the transmission 98 may be driven by a suction motor or a turbine, for example a belt drive, to provide torque to the output end 90. In other embodiments, the transmission 98 may be driven by a suction motor or a turbine.

[0025] Reference Figure 3-8 , the brush roller 70 includes a first end 102 and a second end 106 opposite the first end 102. The brush roller axis A1 extends through the first end 102 and the second end 106, and the brush roller 70 rotates about the brush roller axis A1. A brush roller material 110 is disposed along the outer surface of the brush roller 70, such as bristles, bristle strips, wings, microfibers, tufted fibers, or other materials. In the illustrated embodiment, the brush roller material 110 is microfibers or tufted fibers and extends between the first and second ends 102, 106. The second end 106 includes an input end 114, which is coupled to the output end 90 of the drive mechanism 86 when the brush roller 70 is coupled to the base 12. In the illustrated embodiment, the input end 114 forms a keyed or splined connection with the output end 90 such that one of the input end 114 and the output end 90 includes a groove to receive a keyed or splined drive member disposed on the other of the input end 114 and the output end 90, which allows the input end 114 to rotate synchronously with the output end 90, and the brushroll 70 (e.g., brushroll material 110) to rotate synchronously with the input end 114, thereby allowing the drive mechanism 86 to rotate the brushroll 70 about the brushroll axis A1 during at least some operating modes of the surface cleaner 10. Thus, when the brushroll 70 is coupled to the base 12, the second end 106 is supported by the drive mechanism 86.

[0026] Continue to refer to Figure 3-8 , the first end 102 of the brush roller 70 includes a first end 102 that can be selectively positioned in an unfastened position ( Figure 5 ) and fastening position ( Figure 3 ), in which the brush roll 70 can be removed in the unfastened position, and in which the brush roll 70 is fastened to the base 12. When in the fastened position, the arm 118 prevents the brush roll 70 from being removed from the base 12, and the latch 74 is in the locked position, and when in the unfastened position, the arm 118 allows the brush roll 70 to be removed from the base 12. The arm 118 is rotatably coupled to the first end 102 and extends away from the brush roll axis A1 (e.g., transverse to the brush roll axis A1 in a radial direction). The arm 118 is supported so that the brush roll 70 can rotate relative to the arm 118 during operation.

[0027] Reference Figure 3 and 4 , when the brushroll 70 is coupled to the base 12, the arm 118 forms an outer surface 134 of the first side 54 of the base 12. The brushroll material 110 extends adjacent to the brushroll first end 102 such that the brushroll material 110 is adjacent to the arm 118. As such, the distance between the outer surface of the first side 54 and the brushroll material 110 is a function of the thickness of the arm 118, which reduces the distance between the outer surface of the first side 54 and the brushroll material 110 as compared to prior cleaners. When the surface cleaner 10 is operated with the first side 54 adjacent to a wall, this reduces the distance between the brushroll material 110 and, for example, a wall and enables a user to clean close to the wall.

[0028] Reference now Figure 7-8 , the arm 118 includes a hole or pocket 122, which is disposed on the lower side or end of the arm and can be disposed closer to the distal end of the arm 118 than the brush roller axis A1. The pocket 122 can be a blind hole that extends partially into the arm 118. When the brush roller 70 is coupled to the base 12 and the arm 118 is in a secured position, the pocket 122 receives a portion of the base 12 therein to prevent the brush roller 70 from moving along the brush roller axis A1. In a specific embodiment, the arm 118 further includes a groove 126 disposed between the pocket 122 and the brush roller axis A1. When the brush roller 70 is coupled to the base 12, the pocket 126 engages a portion of the base 12 and the arm 118 is in a secured position to prevent the brush roller 70 from moving along the brush roller axis A1. Finally, the arm 118 of the illustrated embodiment includes a handle or grip 130 to facilitate a user grasping the arm 118 and moving the arm between a secured position and an unsecured position.

[0029] Reference Figure 5-8 , the base 12 includes a protrusion 138 that can be received in the receptacle 122 when the arm 118 is in the secured position and a retaining wall 142 that can engage with the groove 126. The position of the protrusion 138 in the receptacle 122 and the position of the retaining wall 142 outside the groove 126 prevent the brush roller 70 from moving along the brush roller axis A1 when the arm 118 is in the secured position. In addition, the protrusion 138 and the retaining wall 142 support the arm 118 relative to the base 12 in the secured position so that the arm 118 supports the first end 102 of the brush roller 70 relative to the base 12. In the illustrated embodiment, the base 12 further includes a secondary latch 144 ( Fig.10), when the arm 118 is in the secured position, the secondary latch 144 prevents upward movement of the arm 118. In the illustrated embodiment, the secondary latch 144 is a deformable hook that engages a corresponding latch pin 145 on the arm 118. When the latch 74 is moved to the unlatched position when the housing 82 is removed from the base 12, the secondary latch 144 holds the arm 118.

[0030] Reference Figure 6 9a, the latch 74 is shown supported by the base 12 not in the unlocked position to selectively prevent movement of the brush roll 70. More specifically, the latch 74 is disposed closer to the first side 54 of the base 12 than the second side 58 of the base 12 and is movable relative to the base 12 between an unlocked position in which the brush roll 70 can be removed from the base 12 when the shell 82 is removed from the base 12 and a locked position in which the brush roll 70 is coupled to the base 12 to rotate about the brush roll axis A1 when the shell 82 is attached to the base 12. Figure 3 9b is shown in the locked position, engages with the arm 118 when in the locked position to maintain the arm 118 in the secured position. The latch 74 prevents the arm 118 from moving from the secured position to the unsecured position. In the illustrated embodiment, the latch 74 is movable in a direction parallel to the brushroll axis A1, and the latch 74 is disposed closer to the first side 54 of the base 12 when in the locked position to prevent the arm 118 from moving. In one embodiment, the latch 74 is rotatable between the locked position and the unlocked position.

[0031] Referring to FIGS. 9a and 9b, the latch 74 includes a catch portion 146 that engages with the arm 118 when the latch 74 is moved toward the locked position. The catch portion 146 is configured to engage with a portion of the arm 118 to prevent the arm 118 from moving toward the unfastened position. In one embodiment, the catch portion 146 includes a chamfer so that if the arm 118 is not completely in the fastened position, the chamfer on the catch portion 146 engages with a corresponding surface on the arm 118 and presses the arm 118 toward the fastened position when the shell 82 presses the latch 74 toward the locked position. The latch 74 further includes a follower 150, which, as described in detail in this application, can be engaged by the brush roller shell 82 to move the latch 74 from the unlocked position toward the locked position. The spring member or resilient member applies a force to the latch 74 toward the unlocked position. The spring member shown is a coil spring 154 that pushes the latch 74 toward the unlocked position when the shell 82 is removed.

[0032] like Figure 5As shown, the movement of the arm 118 between the fastened position and the unfastened position may include rotation. In other embodiments, the movement of the arm 118 to the unfastened position includes rotation and translation. In other embodiments, the arm 118 is configured to translate to the unfastened position. In the illustrated embodiment, when the arm 118 is in the unfastened position by the user lifting the first end 102 of the brush roll 70 away from the base 12 in a vertical direction, releasing the input end 114 of the second end 106 from the output end 90 of the drive mechanism 86, and releasing the brush roll 70 from the base 12, the brush roll 70 can be removed from the base 12. When the base is set on the drip tray 164 ( Fig.11 ) or other containers that may restrict the movement of the brush roller in the axial direction of the brush roller, the brush roller 70 can be removed from the base 12 by vertically moving the first end 102 to remove the brush roller 70. Such an arrangement allows the drip tray 164 to conform to the shape of the base, thereby reducing the size and cost of the drip tray, while maintaining the convenience of removing the brush roller when the base 12 is in the drip tray.

[0033] 9, the brushroll housing 82 is releasably coupled to the base 12 to cover a portion of the brushroll 70 during operation of the surface cleaner 10. When the brushroll housing 82 is attached to the base 12, an actuator 158 extending from the brushroll housing 82 cooperates with the latch 74 to move the latch 74 toward the locked position. When the brushroll housing 82 is coupled to the base 12, the actuator 158 extends from the brushroll housing 82 toward the surface, and the actuator 158 includes a cam surface 162 that engages the follower 150 to move the latch 74 toward the locked position when the housing 82 is installed. More specifically, the cam surface 162 and the follower 150 are oriented so that movement of the actuator 158 transverse to the brushroll axis A1 causes the latch 74 to move in a direction along the brushroll axis A1. When the actuator 158 moves with the housing 82 toward the housing's installed position, the cam surface 162 engages the follower 150 and presses the follower 150 and the latch 74 toward the first side 54 of the base 12 into the locked position against the force of the spring 154, and when the housing 82 and the actuator 158 move away from the base 12, the actuator 158 disengages from the follower 150, allowing the latch 74 to move toward the second side 58 of the base 12 under the force of the spring 154 into the unlocked position. In the illustrated embodiment, the actuator 158 is integrally formed with the brushroll housing 82 and can be removed from the base 12 with the brushroll housing 82. In one embodiment, the actuator 158 is a separate component from the housing 82. Alternatively or additionally, when the housing 82 is removed from the base 12, the actuator 158 remains on the base 12 and can be actuated by the housing 82 or by user interaction. For example, in the embodiment shown in Figures 13a and 13b, the housing 82 does not include an actuator. Instead, the latch 74 includes a finger grip 190 rather than a follower 150 to be actuated by a user and move the latch 74 toward the unlocked position. The latch 74 may include a locking pin (not shown) that engages the base 12 to secure the latch 74 in the locked position until the user disengages the locking pin by applying a force to the finger grip 190. In the embodiment shown, the latch 74 is maintained in the locked position when the brushroll housing 82 is coupled to the base 12, and the latch 74 moves to the unlocked position when the brushroll housing 82 is decoupled from the base 12. In one embodiment, the housing forms part of a fluid flow path that is in communication with the vacuum source 18 and the debris collector 22. In Fig.12 In one embodiment shown, the surface cleaner 10' is a carpet extractor, wherein the housing 82' is a nozzle forming the suction inlet 66'. In another embodiment not shown, the base and housing surround the brush roll 70 so that the first end 102 is not open to the sides, and the suction inlet is formed along the underside of the base below the brush roll, such as for use in a dry vacuum cleaner.

[0034] Reference Figure 3-4, the brush roll housing 82 includes a housing latch 166 that selectively secures the brush roll housing 82 to the base 12. The actuator 170 is supported by the brush roll housing 82 and is movable between a latched position, in which the brush roll housing 82 is secured to the base 12, and an unlatched position, in which the brush roll housing 82 is removable from the base 12. The housing latch 166 includes a spring or spring member that applies a force to the latch 166 toward the latched position. In the illustrated embodiment, the housing latch 166 is a pinch latch and is operable independently of the latch 74 that secures the brush roll 70 to the base 12.

[0035] The brush roll housing 82 of the illustrated embodiment includes a light 174 to illuminate the surface during operation of the surface cleaner 10. When the housing 82 is coupled to the base 12, the light 174 is powered by the surface cleaner 10 and can be removed from the base 12 together with the brush roll housing 82. The base 12 includes a first electrical connector 178, and the brush roll housing 82 includes a second electrical connector 182. When the brush roll housing 82 is coupled to the base 12, the first and second electrical connectors 178, 182 are operably coupled to each other. Therefore, when the brush roll housing 82 is coupled to the base 12, there is an electrical connection between the base 12 and the brush roll housing 82 so that the surface cleaner 10 can be operated to power the light 174.

[0036] To remove the brushroll 70 from the surface cleaner 10, the operator first removes the brushroll housing 82 by releasing the housing latch 166. When the brushroll housing 82 is coupled to the base 12, the brushroll 70 cannot be removed from the base 12. The brushroll housing 82 does not directly engage the brushroll 70 to secure the brushroll 70 to the base 12. However, removal of the brushroll housing 82 allows the latch 74 to move to the unlocked position. More specifically, removal of the brushroll housing 82 disengages the actuator 158 from the latch 74 and allows the spring to move the latch 74 toward the unlocked position, wherein in the unlocked position, the latch 74 is not engaged with the arm 118. The operator then moves the arm 118 from the secured position ( Figure 3 ) to the unfastened position ( Figure 5 ), to disengage the secondary latch 144 and decouple the protrusion 138 from the receptacle 122 and the retaining wall 142 from the recess 126. Once the arm 118 is rotated to the unfastened position, the brushroll 70 can be removed from the base 12. More specifically, the operator can then move the brushroll 70 away from the second side 58 of the base 12 to disengage the input end 114 from the output end 90. In the illustrated embodiment, the operator can remove the brushroll 70 by lifting the first end 102 of the brushroll 70 away from the base 12 and vertically.

[0037] Although the present disclosure has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects of the present disclosure.
