ABSTRACT:
To scrub adjacent parallel grout lines on a tile floor simultaneously, a long handle is attached to a base which is wider than the space between adjacent grout lines. Two or more long narrow scrubbing elements are adjustably mounted on the base with the long sides parallel to one another. They are spaced apart to correspond to the spacing between tiles and locked in position. When they are moved back and forth in a scrubbing motion, they tend to remain in the depressed grout lines so they are self-guiding. All the scrubbing effort is directed to the grout lines which tend to accumulate dirt more than the elevated, impervious tile surface. The scrubbing elements may be bristle brushes, foam or fibrous scrubbing material. An electric motor driven embodiment is shown with rotary brushes adjustably mounted on a rotary shaft.
