摘要： An extractor has a plurality of fluid delivery needles mounted to a housing in fluid communication with a fluid distribution system and positioned to penetrate a carpet surface to deliver a cleaning solution below the surface of the carpet and into the carpet nap. Soiled cleaning fluid is removed from the surface with suction. A method of cleaning a carpet or a pet coat having a nap comprises injecting cleaning fluid, such as a foam detergent, directly into the nap and removing soiled cleaning fluid from the carpet.

摘要： An extractor has a duct door moveably mounted to a working air conduit for movement between a first position at which normal suction at a suction nozzle is reduced and a second position at which normal suction at the suction nozzle is unreduced. An actuator is connected to the duct door for selectively moving the duct door between the first position and second position. In one embodiment, a suction leak hole is formed within the working air conduit and the duct door is moveable with respect to the leek hole to selectively fluidly open and close the leak hole. In another embodiment, the duct door is moveable within the working air conduit to selectively fluidly restrict the working air flow in the working air conduit and the actuator selectively moves the duct door between the first and second positions. The suction reduction selectively increases the cleaning solution dwell time.

摘要： The invention relates to a water extraction cleaning machine having a variable solution mixing valve adapted to create cleaning solution mixtures of variable constituent ratios. Clean water and detergent are provided from tanks supported on the water extraction cleaning machines. The size of the detergent inlet opening can be altered through rotation of a control knob provided on the outside of the water extraction cleaning machine. The knob is interconnected to at least one member which is adapted to vary the size of one of the detergent fluid inlet and the clean water inlet so that the ratio of constituent elements can be altered depending upon the cleaning application.

摘要： A water extraction cleaner comprises a system for delivering clean solution to a surface to be cleaned, a system for extracting dirty solution and air from such a surface, and a housing supporting the delivery system and the extraction system. The housing defines a recess for receiving a pair of tanks, an upright front surface of the recess being complementary to upright rear surfaces of the tanks. The housing is also provided with a pivot surface spaced from the upright surface of the recess and engageable by lower end portions, the pivot surface being formed and disposed to hold the upright surfaces of the tanks in snug engagement with the upright recess surface. Each of the tanks may be mounted on the housing by tilting the tank to insert the lower end portion thereof into the recess and then rotating the tank to an upright position about the pivot surface. The delivery system includes an inlet on the housing disposed to receive clean solution from one of the tanks when it is received in the recess in the upright position. The extraction system includes an outlet on the housing disposed to deliver dirty solution and air to the other of the tanks when it is received in the recess in the upright position. A detent arrangement is provided to removably secure the tanks on the housing in these operative positions, and the clean-solution tank includes a valve mechanism automatically actuated to permit flow from the tank when it is in its operative position.
