ABSTRACT:
An apparatus for cleaning swimming pools in a stepwise movement over the pool walls comprises a balanced operating head having an inlet and an outlet, the outlet adapted to be swivelably connected to a longitudinally resilient and flexible suction hose. The inlet axis is inclined at an angle of between thirty degrees and sixty degrees to that of the outlet. A passage extends through the head from inlet to outlet, and an oscillatable valve in the head is adapted to alternately open and close said passage. A baffle plate is disposed in the head between the inlet and valve to form a restricted suction connection between inlet and outlet around the valve when the passage is closed, the connection being as restricted as practical commensurate with proper valve movement.
