Abstract
A mobile surface scrubber for scrubbing a surface wetted with cleaning solution. The scrubber comprises a frame, a plurality of wheels rotatably mounted on the frame, scrub brush means attached to the frame and positioned to scrub the wetted surface as the scrubber is transported over the surface, and a recovery system for recovering cleaning solution from the surface. The recovery system includes a return tank for retaining recovered cleaning solution, a rear squeegee pivotally connected to the frame, and left and right side squeegees mounted on the frame. The rear squeegee is positionable to contact the surface behind the scrub brush means when the scrubber is transported in the forward direction. The side squeegees are unvaryingly oriented with respect to the frame and positionable to contact the surface on opposite sides of the scrub brush means. The rear squeegee is so constructed and operable that when the scrubber is transported in a right turning direction, the rear squeegee pivots relative to the frame to a position in which the right end of the rear squeegee overlaps the rearward end of the right side squeegee, and when the scrubber is transported in a left turning direct…
