Carpet wheel for a rotary cleaning apparatus

Abstract

A carpet wheel is provided for a rotary cleaning apparatus of the type having an electric motor in a housing, a brush member attached to a drive shaft of the motor, a holding tank for a liquid cleaning fluid and a handle extending at an angle upwardly from the holding tank. The carpet wheel comprises a circular shaped base member. Elements are on the base member in a pattern, for forming a plurality of radially extending grooves. The groove forming elements can be releasably positioned against the underside of the brush member, to be rotated thereabout. A plurality of balls are also provided. A structure is for rotatively carrying the balls in the base member, in spaced apart radially extending locations under every other groove, so that the balls will contact and roll upon a carpet. Components are in the base member in every other groove between the grooves with the balls, for allowing the liquid cleaning fluid coming down from the brush member to pass therethrough, to lubricate the balls, so as to evenly apply the liquid cleaning fluid into the carpet to be cleaned.

Dependencies are inferred from the claim text.
