Abstract

The push brush carpet or hard surface cleaner of the present invention is preferably comprised of a cleaning brush with a round surface area to which cleaning bristles of any conventional size and shape are attached. The brush is preferably attached to a frame by use of an axle, wheel and bearing configuration which permits locking of the axle in place at a given rotary position of the brush and also unlocking of the axle to permit rotation of the brush to a different position. In use, the rotary brush is locked in place in a given rotary position by the user, and a portion of the brush surface will come in contact with the carpet or hard surface as the user pushes the brush in a preferably reciprocating motion. In so doing, debris on the carpet or hard surface is agitated and/or expelled by the contacted area of the brush surface. After one area of the brush surface has been exposed to debris, the axle, bearing and wheel configuration permits unlocking, rotation and re-locking of the brush to permit a different portion of the brush surface to contact the carpet or hard surface. In practice the brush is preferably pushed over the carpet or hard surface to agitate and/or expel a debris-laden cleaning solution that has been previously applied to the carpet or hard surface to accomplish cleaning. Finally, the axle, bearing and wheel configuration permits easy disassembly of the brush to allow easy replacement of the brush and to permit accommodation of various brush sizes and bristle varieties.
