ABSTRACT:
A vacuum extractor has a tank assembly including an outer tank and a coaxial inner tank. The inner tank has an open top which is reversibly closed by a cover assembly which includes a vacuum source and a liquid pump. The cover assembly also includes a hose connection in communication with said inner tank and said vacuum source enabling said inner tank to receive either wet or dry materials. The outer tank is substantially closed having an input port closed by a closure member configured in the form of a measuring cup. The outer tank is used for containing a cleaning material which can be accessed through a hose which passes through an aperture in the outer wall of the tank. The hose has an external connector for supplying cleaning material to the liquid pump in the cover assembly which, in turn, supplies the cleaning material to a cleaning tool. The unit is supported by casters which are recessed into the bottom of the tank assembly. A pair of opposed caster recesses are shaped to provide handholds to assist in emptying the separate tanks. The inner tank can be emptied by pouring in a first direction while both inner and outer tanks can be emptied simultaneously by pouring in a second direction opposite to the first direction.
