Abstract
Abstract A vacuum cleaner for professional and household purposes, with actuating elements for introducing the individual apparatus functions, including, for instance, turning the blower motor on and off, rewinding the power supply line into the housing interior, and changing the suction capacity. The actuating elements are capable of being actuated by foot. The actuating elements are combined in the form of a pedal strip arranged in a lower part of an end face or side of the vacuum cleaner. The pedal strip is arranged below the opening for the suction hose. The pedal strip extends over the width of the side, and forms a lower edge or termination thereof. The pedal strip is located within the outer contour of the apparatus housing. A free space for introducing the foot or shoe tip is arranged above the pedal strip, and the upper surface of the pedal strip may be inclined toward the front. The pedal strip can also be a single piece, with the contacts for actuation of the various functions being arranged in the region of the outer ends, remote from each other, of the strip.
