ABSTRACT:
A surface cleaning and rinsing device has a rotor rotatable in a housing with the underside of the rotor being provided with a plurality of suction nozzles and a plurality of orbitally rotating brushes positioned between said suction nozzles. Adjustable spray nozzles are also provided on the underside of the rotor for spraying a cleaning liquid onto the surface to be cleaned in advance of the brushes with respect to the direction of rotation of the rotor, or liquid supply means dispenses the liquid through the brushes themselves, with each of the suction nozzles serving to extract the liquid and loosened dirt immediately after brushing has occurred. The outer peripheries of the brushes are caused to rotate in the opposite direction from the rotor itself, and the brushes are turning at a rotational speed significantly faster than the rotor; therefore, they are able to lift up and flip over the pile of a rug being cleaned for also cleansing the underside of the pile. An advantageous cyclical scrubbing action on the pile is produced, in which the liquid-dwell-time is machine controlled, and very little over-all liquid is required per square yard of floor covering for achieving thorough cleaning and rinsing.
