Abstract A brush for cleaning and washing surfaces with a scrubbing action, the brush having bristles mounted on a body. The body houses a freely rotatable turbine wheel driven by a jet of water. The turbine wheel is eccentrically weighted so that as it rotates it imparts to the body of the brush and the bristles in a vibrating motion.
