ABSTRACT:
A tank type liquid vacuum cleaner includes, an intake hose, a L-shaped air inlet tube, a liquid tank, an anti-overflow cylinder in the liquid tank, a ball valve in a ball valve containing tube disposed within the anti-overflow cylinder, an air outlet, a suction fan, and a three-stage switch, whereby the vacuum cleaner effectively cleans up dust, debris, dirty air, and the like, can be easily disassembled for cleaning the internal surface of the liquid tank, and can be readily converted to an air cleaner when the intake hose is removed therefrom. Further, the cleaner is constructed so that the liquid in the liquid tank is prevented from spilling when the vacuum cleaner accidentally falls over on the floor.
