Abstract
An inverted plunger for unclogging pipes or toilets is described. The proposed inverted plunger does not have any openings filled with air, at the stretchable elastic bottom part, unlike all plungers described in the prior art. The proposed inverted plunger is equipped with the internal piston, that allows the pressure application to the narrower part of the stretchable bottom, leading to direct pressure from the stretched material to the liquid inside the pipe, avoiding the air-to-liquid pressure utilized in regular plungers. Using the electric motor in the proposed inverted plunger leads to the increased efficiency and to the easy use by the operator.
