ABSTRACT:
An apparatus or implement for underwater cleaning of swimming pool bottoms and/or walls having a chassis with traction drive and a suction pump mounted on the chassis. A suction nozzle is connected to the suction side of the pump, for drawing in settled particles. A filter is connected to the pressure side of the pump for catching the particles. A controlled diving cell which is floodable and clearable in a controlled manner is arranged on the chassis for varying the buoyancy of the apparatus sufficiently to raise and lower it in the water. A brush with a particular bristle configuration may be mounted in the suction nozzle.
