ABSTRACT:
An apparatus for polishing a floor includes a rotated polishing pad suspended from a housing with a mechanism for maintaining full engagement of the surface of the pad with the floor. This mechanism includes a caster disposed within a centrally-located aperture in the pad and a device, such as a spring, connecting the caster to the housing which increasingly urges the caster and housing away from one another as they progressively approach one another.
