Abstract
A cleaning rotary brush comprises a hard base mounted to a rotary shaft and a plurality of ridged projections formed on and projecting from the working surface of the base , the tops of said ridged projections in contact with an object to be cleaned while rotating in substantially the same plane. The ridged projections are made of a polyvinyl acetal porous elastomer and disposed continually on a plurality of phantom setting lines extending from inner reference, points on the side of the center of rotation of the working surface to outer reference points on the side of the outer periphery of the working surface. The length L in a longitudinal direction of said ridged projections is made longer than the length D in a widthwise direction of the ridged projections . Thus, the spent cleaning liquid containing dirt or particles scrubbed from the portion to be cleaned is guided by the ridged projections , led adequately to outer reference points , and rapidly drained off to the outside of the system.
