  • Patent number: 5280663
    Abstract: A floor scrubbing apparatus has rotating pads and a flexible scrubber guard that encompasses the scrubber during floor scrubbing operations. The scrubber guard protects a work area from contact damage and liquid splash. The scrubber guard comprises a flexible wall having a top edge, an arcuate bottom edge, and continuous, vertically extending interior and exterior surfaces. Parallel, latitudinally positioned ribs project outwardly from, and extend around the entire circumference of, the interior surface of the scrubber guard. These ribs increase the scrubber guard's ability to intercept liquid splash. The arcuate bottom edge allows the scrubber guard to lift upwardly, relative to the surface of a floor, when the exterior surface encounters a vertical structure such as a wall. The arcuate bottom edge also inhibits power cord entanglement with the rotating cleaning pads.
