Abstract (en)
[origin: EP0365191A1] A variable power suction cleaner includes a pressure switch (PS1) at the entrance to a dust filter bag (32), and an air flow switch (PS2) which measures the differential pressure between a point upstream of a diffuser of the fan (20), and a point within the body of the cleaner upstream of an exhaust filter (30). Signals from the pressure switches are compared with limit values stored within a microprocessor memory, to determine whether, for example, the bag is full or the suction hose is blocked.
