The machine has a frame with a disc brush rotatably carried thereby and driven by a motor which is mounted on a plate that is resiliently carried by the frame. A first vacuum nozzle and a squeegee are located at the back of the machine behind the disc brush for picking up cleaning solution when hard floors are being cleaned. The machine has a second nozzle located at the front thereof, in front of the disc brush, for picking up cleaning solution when carpeting is being cleaned and the machine is moved in a rearward direction. A cleaning solution supply tank is located on the frame and a recovery solution tank is located in the supply tank. A vacuum motor is mounted on a lid above the recovery tank and means are provided for connecting the recovery solution tank with each of the exhaust hoses for the two vacuum nozzles.
