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： A floor sweeper for recovering material from a surface to be cleaned comprises a handle assembly pivotably attached to a foot assembly. The foot assembly comprises a housing forming a brush chamber having a bottom opening. The foot assembly comprises a pair of driving gears and a split brush assembly rotatably mounted within the brush chamber and adapted to contact the surface through the opening. The brush assembly comprises two separately-rotatable halves each corresponding to one of the driving gears, with each half comprising a brush core, brush paddles or bristles affixed to an exterior of the brush core, and a brush gear adapted for rotation with the brush core. Each brush gear is driven by a corresponding driving gear to the corresponding brush core as the floor assembly is moved across the surface in order to drive the brushes to cleaning of the surface.

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： A portable surface cleaning apparatus has a base for movement along a surface to be cleaned and an upright handle pivotally attached to a rearward portion of the base. A fluid dispensing nozzle for applying fluid to the surface and a suction nozzle for picking up fluid and debris from the surface are associated with the base. A clean water holding tank and a detergent holding tank are removably mounted to the handle while a recovery tank is removably mounted to the base. A mixing valve is fluidly connected between the holding tanks and the spray nozzle for changing the mixing ratio of the detergent with respect to the water. The fluid recovery tank includes an integrally molded conduit that extends from the suction nozzle and a mounting for an accessory hose that interrupts the fluid path from the suction nozzle in the conduit and redirects fluid flow through the hose. A pump is fluidly connected between the mixing valve and the dispensing nozzle and includes a pump priming valve that operates on negative air pressure to clear air from the fluid lines during pump operation. A free floating brush is pivotally attached to the base for automatically adjusting to different surface conditions during cleaning operations.

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 hand-held vacuum cleaner includes a housing having first and second half housing elements. The housing has a handle and a nozzle. A motor is mounted within the housing for driving a shaft. A fan is mounted on the shaft for rotation therewith. A selectively separable bag assembly is mounted on the housing. A working air channel is formed within the housing for communicating the nozzle with the bag assembly. The air channel terminates in a working air outlet chute positioned within the bag assembly at its open upper end. The shaft is positioned within the housing generally normal to the direction of air flow within the working air channel.

摘要： A package for delivering a cleaning solution to a surface to be cleaned comprises a housing, a pocket in the housing having at least one piercing projection extending into the pocket and a passageway between the pocket and the surface to be cleaned beneath the housing. A sealed packet containing a cleaning solution can be configured to fit into the pocket and can have at least a portion of an outer surface thereof adapted to be pierced by the at least one piercing projection when the packet is placed in the pocket. The cleaning solution can be discharged from the packet when the packet is positioned in the pocket and the packet is pierced by the at least one piercing projection. The cleaning solution can then be dispensed through the passageway onto a surface to be cleaned.

摘要： An extraction cleaner comprises a fluid delivery system and a fluid recovery system. The fluid recovery system includes a centrifugal separator for separating a liquid and debris-entrained working air flow with a tangential air/water inlet, water outlet and air outlet at a lower portion of the separator. The air outlet has a vertical stand pipe that extends upwardly above the tangential air/water inlet and water outlet. The centrifugal separator can be mounted in a plurality of locations on the extraction cleaner thereby offering greater architectural flexibility.
