Cleaning system for walls of swimming pool - includes guide wires beneath surface and detector in cleaning head to ensure head follows prescribed path along pool walls

摘要

The swimming pool cleaning system includes guide wires (2) mounted beneath the surface of the pool. The wires may, for example, be mounted between the wall and the liner of a pool with an inner liner containing the water. The wires define a circuit so that the cleaning head may be guided around the pool, avoiding obstacles. The spacing between the wires is a function of the size of the cleaning head (B). A detector (4) in the cleaning head senses the wires and corrections to the path of the head are made by water jets placed on the hand (11) of the appliance. The correction may alternatively be made by electric or hydraulic motors. ADVANTAGE - The system provides an automatic and thorough technique for cleaning a swimming pool.
