ABSTRACT:
A surface scrubbing machine includes a body, wheels for supporting the body am& cylindrical scrub brushes mounted on the body for cleaning an adjacent surface. There is a clean water solution tank on the body for supplying a cleaning solution to the surface to be cleaned. A recovery tank is positioned on the body and there is a vacuum system for suctioning used cleaning solution from the surface being cleaned and for conveying it to the recovery tank. A filter is positioned in the recovery tank and there is a pump for transferring filtered solution from the downstream side of the filter to the clean water solution tank. A conduit extends from adjacent the downstream side of the filter to atmosphere and there is a solenoid for intermittently opening and closing the conduit to apply intermittent pressure against the downstream side of the filter to remove soilage from its upstream sides
