ABSTRACT:
A machine for cleaning a surface is provided. The machine includes a forward drum brush unit designed primarily for sweeping and a rear disc brush unit designed primarily for scrubbing. Squeegees are located behind the disc brushes. Cleaning solution is supplied between the drum brush and the disc brushes and is directed toward the drum brush to achieve a wet sweeping action thereby. The disc brushes are mounted for movement toward and away from the surface to be cleaned and are engagable with the surface under controllable pressure. The drum brush is mounted on a separate frame and is engagable by the disc brush unit so that it can be raised for transportation purposes when the disc brush unit is raised. The squeegees can be raised independently of the brushes.
