ABSTRACT:
A portable compact extractor having permanent solution and recovery tanks integrally formed in a single main tank portion, with a removable power head attached to the top of the main tank. A fill port passes through the powerhead into the cleaning solution tank and a pour spout is formed in the recovery tank. With this construction, the cleaning solution tank may be filled with water and, if desired, detergent, by pouring the water and detergent into the fill port in the power head, and the recovery tank may be emptied as desired simply by tipping the unit and pouring the contents of the recovery tank out the pour spout and down the drain, without ever having to remove any tanks, bottles or the power head from the unit, or disconnect and reconnect any tubes. A carry handle is located on the powerhead to facilitate transportation of the unit, removal of the power head from the main tank for cleaning the tanks when desired, and to facilitate pouring the contents of the recovery tank out of the pour spout. A blower located in the powerhead provides suction in the recovery tank for suctioning liquid from a surface into the recovery tank and for driving a pneumatically driven pump for providing a source of pressurized cleaning solution for application to a surface to be cleaned.
