SWEEPER/SCRUBBER SYSTEM CAPABLE OF HANDLING LARGE DEBRIS

Abstract:

A sweeper/scrubber assembly may be used to clean a floor surface without dry sweeping or mopping solid debris from the floor surface before conveying the sweeper/scrubber assembly over the floor surface. In some examples, the sweeper/scrubber assembly includes at least two counter-rotating brushes, a cleaning fluid dispensing system, a vacuum squeegee, and a solid debris collection reservoir. The cleaning fluid dispensing system can dispense cleaning fluid on the floor being cleaning and or one or both brushes. The vacuum squeegee can be positioned against a face of one of the brushes and can apply a vacuum suction force to the face of the brush. The solid debris collection reservoir can be a space not exposed to a vacuum force that collects solid debris thrown by the rotating brushes.
