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.
