Grout cleaning apparatus

Abstract

An improved grout cleaning apparatus has in line cleaning wheels positioned within a housing, at the terminus of a shaft. A grip is coupled at an upper end of the shaft, and may be grasped by a user to move the apparatus for cleaning purposes. In one embodiment, a drive motor supplies power to the in line cleaning wheels, which may be made to turn in opposing directions so as to provide improved cleaning efficiency. A cleaning fluid dispenser may also provided on the shaft, to permit the dispensing of fluid proximate the cleaning wheels during operation.

Description

RELATED APPLICATION[0001]This non-provisional application claims priority to provisional application No. 60 / 919,560, filed Mar. 23, 2007.FIELD OF THE INVENTION[0002]The present invention relates generally to the cleaning of tile grout and, more particularly, to an improved grout cleaning apparatus.BACKGROUND OF THE INVENTION[0003]Tile grout is known to be a repository of dirt. It has a tendency to absorb surface dirt, and to become discolored in the process of doing so. That discoloration can be unsightly, and can harm the appearance of an otherwise attractive tile floor.[0004]Cleaning tile grout can be labor-intensive and physically challenging. Many grout cleaning methods require a user to kneel on the floor, and to manually scrub the grout surface, with a toothbrush-type device or sponge, to obtain a cleaning benefit. These approaches may be inefficient, may damage the grout, and / or may be physically uncomfortable for certain persons, and may create an unwanted exposure to contac...
