A recirculating pump system is connected to either skimmers, or a catch basin for a vanishing edge of a swimming pool, to supply water to the suction inlet of the pump system. A water distribution valve operated by an electric control system distributes water from the outlet side of the recirculating pump system to pool cleaning heads normally in accordance with a preprogrammed timed sequence. As part of each programmed cycle of operation of the water distribution valve, water is supplied to one or more pool return jets located on a side opposite the skimmer or catch basin. The return jets create moving surface currents on the water to sweep debris floating on or near the water surface to the skimmer or catch basin. An electric wind speed detector located in the vicinity of the pool and coupled to the electric control system causes the control system to override the programmed sequence in response to wind exceeding a pre-established threshold to operate the pump system to supply water to the pool return jets.
