ABSTRACT:
An upright vacuum cleaner has a cleaner body; a suction port assembly hinged to the cleaner body with a drum brush mounted on a front lower surface thereof; and a height adjusting apparatus set to an active mode or an inactive mode. In the active mode, the height adjusting apparatus raises the rear portion of the suction port assembly from an initial height, with the drum brush spaced from a surface, to bring the drum brush into contact with the surface when the cleaner body tilts from an upright position towards the rear of the suction port assembly. In the inactive mode, the rear portion of the suction port assembly remains at the initial height when the cleaner body tilts from the upright position towards the rear of the suction port assembly.
