ABSTRACT:
An apparatus for cleaning bathroom and other tile floors and similar tile surfaces includes a wheel-supported frame on which a motor-driven cylindrical scrubbing brush is mounted for surface engagement, the brush being particularly provided with plural circular rows of relatively long, stiff bristles at spacings along the length of the brush member corresponding to the spacings between the grout lines of the tile surface and a plurality of spiral rows of relatively shorter, softer bristles extending helically along the length of the brush member intermediate the circular bristle rows. Upon motor driven rotation of the brush member, the circular and spiral bristle rows are effective respectively to scrubbingly engage the grout lines and the tile surfaces for effective cleaning thereof.
