Remote control device for an integrated suction cleaner installation comprising a suction cleaning unit (1) pneumatically connected to a system of tubes (13) which open, at their ends (13A), onto couplings (11) into which the mating end (9) of a hose (8) is inserted, the latter having at its other end (8A) a handle (5) onto which are fitted the cleaning accessories. The remote control device is of the type using acoustic transmission via the tube system (13) between the suction cleaning unit (1) and the couplings (11), and means (19, 23 and 28) for detecting the specific acoustic pressure wave and operating said unit (1). The device is characterized in that said acoustic pressure wave generating means consist of the hose (8) which, when connected to one of the suction cleaning couplings (11), produces, after handling, a specific acoustic wave conveyed by the tube system (13) to the detecting means (19) and operating means (23 and 28) of unit (1). |
