ABSTRACT:
Water-powered rotating brush device for use in a shower, having an elongated handle portion embodying a supply channel and a return channel, a flexible supply and return hose-pair connectable to the lower end of the handle, and a head portion which rotatably mounts a pair of eccentrically located gear rotors with the larger of the rotors having more teeth than the smaller, the rotors arranged so as to be positively displaced into rotary action by the flow therethrough of water under pressure. A massage brush is coupled to the larger gear rotor. A diverter valve rotatably mounted in the handle may be operated to cut off flow to the rotors and to shunt water from the supply channel directly to the return channel. A relief valve includes a spring biased piston that is displaceable by excessive pressure at the rotor head to open a relief port which allows water to by-pass the rotors and flow directly to the return channel.
