ABSTRACT:
A self-propelled machine includes a main housing supported on front and rear drive rollers and has an operator control handle extending from the rear. Front and rear elongated working brushes are driven in orbital movement in horizontal planes, with the front brush being positioned ahead of the front roller and the rear brush positioned behind the rear roller. A supply tank for the working solution includes agitating and aerating means for creating a foam dispensed from a pressurized tank through a flow control gate, and applied to the floor surface ahead of the front brush. The drive rollers act as squeegies. A collection system includes vacuum pickup nozzles adjacent each of the drive rollers for picking up material from the floor surface which is collected in a collection tank.
