Integrated vacuum cleaning system with a controlled central suction unit connected by a network of airtight tubes to sockets for connection of the cleaning hose

摘要

System characterised in that: A) the connecter (C) is equipped with a radio emitter (16) caused, by the insertion of the connecter (C) into a socket (P1-P5), to emit a first encoded radio signal (S1), and caused, by the removal of the connecter from the socket, to emit a second encoded radio signal (S2), B) the central suction unit (1, 2, 3) being provided with a radio receiver (17) which picks up the encoded radio signals from the connecter (C), the first signal (S1) causing it to start and reception of the second signal (S2) causing it to stop. <IMAGE>
