Abstract (en)
[origin: WO02051297A1] A control method for a vacuum cleaner (1) including a control means (7) to perform control algorithms, a motor (6) to drive a fan (8) that provides suction, a dust sensor (2) placed on the dust passageway and including a light emitter (3) and a light receiver (4) to detect dust passing through the dust passageway, and indication means (5) to give an indication to the user when the dust sensor (2) is dirty. The voltage variations pattern is observed at the light receiver (4) output and a series of comparisons are made in order to decide whether the place is dusty or the dust sensor (2) is dirty.
