Abstract: A water vortex brush has a rotor connected with a brush member and rotatable by a water supplied to the rotor and exiting from the brush member. The water forms a vortex in the interior of the rotor, and the latter is provided with an opening communicating with outside air so that the outside air is aspirated by a negative pressure existing in the central area of the rotor and thereby nullifies the same. The brush has water discharge openings radially offset relative to the air aspirating opening. A rotatable and angularly bent handle, forming simultaneously a water supply conduit, is provided. The bristles of the brush member are selected so as to form a very thin layer at their periphery under the action of a centrifugal force during the operation of the brush.
