Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A floor treatment and cleaning device comprising:
 a chassis member operable to support cleaning device components;   a cleaning deck operable to selectively receive a roller brush;   a roller brush having a first end, a second end, and a longitudinal axis, and wherein the roller brush is rotatable relative to at least one of the chassis member and the cleaning deck;   wherein the roller brush comprises a plurality of bristles extending therefrom;   a stationary brush provided proximal to a first end of the roller brush, and wherein the stationary brush comprises bristles that are operable deflect debris.   
     
     
         2 . The floor treatment and cleaning device of  claim 1 , wherein the bristles of the stationary brush are substantially perpendicular to the longitudinal axis of the roller brush. 
     
     
         3 . The floor treatment and cleaning device of  claim 1 , wherein at least one of the first end and the second of the roller brush is selectively connected to a bearing assembly. 
     
     
         4 . The floor treatment and cleaning device of  claim 3 , wherein the stationary brush is provided at least partially between the roller brush and the bearing assembly. 
     
     
         5 . The floor treatment and cleaning device of  claim 1 , wherein the second end of the roller brush is provided in communication with a drive member and the first end of the roller brush is connected to a bearing assembly to allow rotation of the brush. 
     
     
         6 . The floor treatment and cleaning device of  claim 1 , further comprising a plurality of wireframe guard members, wherein at least portions of the wireframe guard members extend perpendicularly relative to the longitudinal axis of the roller brush and wherein the wireframe guard members are operable to prevent a carpet from being drawn into the device. 
     
     
         7 . The floor treatment and cleaning device of  claim 1 , wherein the plurality of bristles extending from the roller brush are provided in a helical distribution. 
     
     
         8 . A floor treatment and cleaning device comprising:
 a cartridge member operable to selectively and rotatably receive a first roller and a second roller;   a first roller brush and a second roller brush, wherein the first roller brush and the second roller brush each comprise a longitudinal axis;   the first roller brush being spaced apart from the second roller brush, and wherein the longitudinal axis of the first roller brush extends parallel to the longitudinal axis of the second roller brush;   the first roller brush and the second roller brush each comprising a plurality of bristles extending therefrom;   wherein at least one of the first roller brush and the second roller brush is rotatably connected to a bearing assembly;   a stationary brush provided proximal to the bearing assembly, wherein the stationary brush is operable to contact and deflect debris provided on at least one of the first roller, the second roller, the plurality of bristles, and the bearing assembly to prevent ingress of the debris into the bearing assembly.   
     
     
         9 . The floor treatment and cleaning device of  claim 8 , wherein the stationary brush comprises a selectively removable brush. 
     
     
         10 . The floor treatment and cleaning device of  claim 8 , wherein the device comprises a cleaning deck and the cartridge member is selectively connected to the cleaning deck. 
     
     
         11 . The floor treatment and cleaning device of  claim 8 , wherein the stationary brush comprises bristles that extend in a direction substantially perpendicular to the longitudinal axis of the first roller brush and the second roller brush. 
     
     
         12 . The floor treatment and cleaning device of  claim 8 , wherein the stationary brush is selectively connected to the cartridge member. 
     
     
         13 . The floor treatment and cleaning device of  claim 8 , wherein the stationary brush is provided at least partially between the first roller brush and the bearing assembly. 
     
     
         14 . A floor treatment and cleaning device comprising:
 a roller brush having a first end, a second end, and a longitudinal axis, and wherein the roller is rotatable about the longitudinal axis;   wherein the roller brush comprises a plurality of bristles extending therefrom;   a stationary brush provided proximal to a first end of the roller brush, and wherein the stationary brush comprises bristles that extend substantially perpendicularly relative to the longitudinal axis, the stationary brush being operable to deflect and contain dirt and debris displaced by the roller brush.   
     
     
         15 . The floor treatment and cleaning device of  claim 14 , wherein the stationary brush comprises a rigid base and the bristles extend from the rigid base. 
     
     
         16 . The floor treatment and cleaning device of  claim 15 , wherein the rigid base is selectively securable to the cleaning device. 
     
     
         17 . The floor treatment and cleaning device of  claim 14 , wherein at least one of the first end and the second of the roller brush is selectively connected to a bearing assembly. 
     
     
         18 . The floor treatment and cleaning device of  claim 17 , wherein the stationary brush is provided at least partially between the roller brush and the bearing assembly. 
     
     
         19 . The floor treatment and cleaning device of  claim 14 , further comprising a plurality of wireframe guard members, wherein at least portions of the wireframe guard members extend perpendicularly relative to the longitudinal axis of the roller brush and wherein the wireframe guard members are operable to prevent a carpet from being drawn into the device. 
     
     
         20 . The floor treatment and cleaning device of  claim 14 , wherein the plurality of bristles extending from the roller brush are provided in a helical distribution.
