A system, and apparatus for cleaning carpet and textile floor coverings which provides for a first detergent spraying followed by a second jet spraying with a liquid incorporating a cationic surfactant accompanied by a substantially simultaneous suctioning off of the deposited second liquid. The apparatus of the system includes a mobile frame arrangement with two adjacent tanks, one carrying cleaning solution and the other carrying the noted surfactant. Solenoid actuated valves control the delivery of these liquids through a wand to the carpet being cleaned. The apparatus includes a power conserving feature providing for a direct coupling between the motor of the apparatus and a suction blower and a simultaneous belt drive coupling to a liquid pump. The design of the apparatus is such as to minimize the physical effort required during its use. Among the features lessening the amount of this work effort is a semi-automatic tank filling arrangement including metering valves for adding proper amounts of liquid detergent and surfactant during the process.
