ABSTRACT:
A centralized suction cleaning installation comprises a network of fixed pipes connected to suction generating means. Air intakes to which said pipes are connected are adapted to have portable cleaning tools coupled to them. An upper end of a first chamber is coupled to the suction generating means. Its lower end is connected to the fixed pipe network and to an evacuation pipe incorporating a first valve. A first storage tank in the lower end of the first chamber is filled with water to the level of the evacuation pipe. Air sucked into the installation is bubbled through the water in this tank. A second water storage tank in a second chamber is connected to a pressurized water supply by a float valve and by a second valve to the first chamber. A three-way solenoid valve connected to the pressurized water supply operates the float valve and the first and second valves. It is controlled by a switch integrated into a hook or other support for the portable tools.
