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 position behind the rear roller. A pressurized supply tank for the working solution includes agitating and aerating means for creating a foam, and includes an adjustable control gate for controlling the flow of foam through dispensing passages to the floor surfaces ahead of the front brush. The drive rollers act as squeegees. A collection system includes vacuum pickup nozzles adjacent each of the drive rollers for picking up material from the floor surface, which material is collected in a collection tank.
