Abstract:
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.
