ABSTRACT:
A cleaning device for scrubbing a floor surface including a rotatable cleaning disc. A circular ring surrounds the disc and terminates downwardly in spaced, flexible skirts which contact the floor surface. A flexible arm mounts the ring to permit vertical adjustment of the ring relative to the cleaning disc to compensate for brush wear and other irregularities. One or more flexible conduits intercommunicate between the interior of the ring and a hollow hub, and suction forces are applied through the conduit to the ring to remove dirty water from the floor and into machine mounted reservoir.
