Vacuum cleaner (1911)

In this hand-operated vacuum cleaner, which has been recently placed on the market, a bellows, strapped to the back and around the waist, provides the suction. A lever, worked to and fro by the left hand, operates the bellows, and the right hand directs the suction nozzle. The dust is drawn into the bellows, where it is confined by the means of porous felt.
