Abstract
The vacuum cleaner includes a housing (2) having a dust compartment (11) containing a dust bag (17) and a vacuum compartment (12) containing a motor-ventilator set (20); a vacuum hose (3, 5) coupled to a suction unit (7) with a suction aperture; and a device (30) for automatically controlling the power of the motor-ventilator set (20), comprising a sensor (50) for the type of flooring and a fuzzy logic control unit (46). The automatic control device (30) of the invention further includes a sensor (60) for detecting the dynamic movement of the suction unit (7), wherein the fuzzy logic control unit (46) is adapted to apply a fuzzy inference operation to the output of the floor-type sensor (50) and to the output of the suction unit dynamic movement sensor (60), so as to control the motor-ventilator set (20) on the basis of the fuzzy inference operation.
