Abstract: System for attaching a membrane on a cleaning device for swimming-pools. The invention concerns a system for attaching a net to a swimming-pool cleaning device, enabling the net to be held perfectly taut and to be correctly and fully attached to a separate container from the cleaning device that can easily be inserted into the device by the user. The invention device consists of a separate container (1) open at each end (2) to enable water to flow through it and containing two hollow half-boxes (3) that can be attached to each other in order to seal the box completely and hold the net in place inside the separate container, either in the body of the separate box, attached by fixing clasps or in line between the two sections of pipe that are attached to the pool pump, by means of conical terminals (6) that can be inserted into the pipe. The device of which the invention consists is designed specifically for the vacuum cleaners cleaners used for cleaning maintenance for the water in artificial pools.

Abstract: The invention concerns a system for chlorinating water by electrolysis and/or light projection for pool operating with mechanical energy of the delivery nozzle. The invention concerns a system for chlorinating water by electrolysis and illumination of pools provided with a water circulating system. The system is easily set on the entire pool without affecting its sealed character and uses a free and safe source of energy, the motive power of the water from the delivery nozzle, the device consisting of a hollow single-unit assembly (1), connected to the delivery nozzle, allowing the water flow to circulate in controlled manner actuating a device with rotational movement (8) connected to a current generator (9) which powers, with variable intensity, alternately or jointly, the sealed light projector (11) and/or the electrolytic cell (12) before exiting into the pool. The inventive device is particularly designed to illuminate and/or chlorinate water of swimming pools.

Abstract: An automatic swimming pool cleaning robot is disclosed, comprising a body, a suction head, an unstable valve, a suction pipe having an upper end, a recuperating filter connected to the upper end, and a venturi injector, wherein the unstable valve is activated to activate the robot. The robot combines the advantages of vacuum-fed robots and pressure-fed robots.
