A plurality of laterally oriented rollers are supported by the chassis for supporting the carpet belt member in a closed path, including a cleaning roller for submerging a portion of the carpet belt within the tank, first and second wringer rollers, first and second press rollers, an adjustment roller for tensioning the carpet roller, an idler roller, and a drive roller. An insert member is supported by the chassis, the cleaning roller and the press roller being supported by the insert member. A main handle pivotally mounted to the insert member manipulates the apparatus on the floor surface. A roller drive rotatably couples the drive roller to at least one of the wheels for regulating a rate of advancement of the carpet belt during longitudinal movement of the apparatus. A platen member supported proximate the bottom extremity of the chassis between the idler and drive rollers for pressing the carpet belt against the floor surface in the at least one operating position of the elevator mechanism.
