A vacuum cleaner has: an air outlet, an air inlet, a dust chamber in communication with the air inlet, a fan driven by a main motor provided in a housing in communication with the air outlet and the dust chamber, a pressure detector which provides a signal showing variations characteristic of the floor type being cleaned; and circuitry, including a neural network for recognizing and classifying the floor type as a function of these variations, a setpoint generator for determining a pressure setpoint as a function of the variations, and a control circuit for controlling the power of the main motor so as to maintain the pressure setpoint.
