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.

[ Wherefore we claim:] [1.] A carpet and upholstery extractor comprising:a cleaning liquid supply tank for providing a source of cleaning liquid, a pump in fluid communication with said supply tank for providing a source of pressurized cleaning liquid, a spray nozzle in fluid communication with said pump for receiving pressurized cleaning liquid from said pump and applying said cleaning liquid upon a surface to be cleaned;a wet pickup nozzle, a recovery tank and a suction producing means fluid in communication with said pickup nozzle and said recovery tank for creating a reduced pressure in said recovery tank for drawing air and soiled cleaning liquid in through the pickup nozzle and into the recovery tank, where the recovered soiled cleaning liquid is separated from the air and collected in the recovery tank;a pour spout having a discharge opening located in an upper portion of said recovery tank at a location spaced above a surface of the collected liquid when said recovery tank is filled to capacity; andwherein a pivotal spout cover extends across and immediately adjacent to said discharge opening, such that upon activation of said suction producing means the reduced pressure in said recovery tank draws the spout cover against said discharge opening and seals said discharge opening, and upon inclination of said extractor toward said pour spout, when said suction producing means is deactivated, the spout cover pivots under the pressure of the collected liquid such said collected liquid may be freely discharged through said pour spout. [7.] A wet pickup vacuum cleaner comprising:a wet pickup suction nozzle, a recovery tank and a motor fan assembly in fluid in communication with said suction nozzle and said recovery tank for drawing air and soiled cleaning liquid in through said suction nozzle and into said recovery tank, where the recovered soiled cleaning liquid is separated from the air and collected in said recovery tank;an open topped pour spout located in an upper portion of said recovery tank; andwherein a pivotal spout cover extends across and immediately adjacent to the open top of said pour spout, such that upon activation of said motor fan assembly the reduced pressure in said recovery tank draws said spout cover against the open top of said pour spout and seals said pour spout, and upon inclination of said vacuum cleaner toward said pour spout, when said motor fan assembly is deactivated, said spout cover pivots under the pressure of the collected liquid such said collected liquid may be freely discharged through said pour spout.
