摘要： An extraction cleaning machine has a solution dispensing system and a recovery system for applying a cleaning solution to a surface and recovering the solution from the surface, and an agitation brush assembly for agitating the surface. The agitation brush assembly can include friction-type or other dampers for reducing brush bounce, and biasing elements for maintaining a constant downward force on the brush. The brush can have multiple helical rows of tufted bristles, preferably at least four rows, or can comprise a continuous helix of bristles in a twisted-wire spindle. The brush can further have a removable fabric cover for mounting over a bristle brush for contacting a surface being cleaned. The brush assembly can function in an upright extraction cleaning machine with or without an above floor cleaning tool, a hand-held extractor, or a hand-held attachment to a canister extractor or an above floor tool in upright extractor.

摘要： A liquid extraction cleaner comprises a solution dispensing system, a liquid recovery system, and an agitation brush assembly. The solution dispensing system includes a cleaning solution supply tank affixed to the cleaner and fluidly connected to a solution spray nozzle through a trigger-operated manual solution spray pump. The supply conduit interconnecting the cleaning fluid supply tank and the spray nozzle traverses a passage formed integrally with the air-liquid separator housing, spray nozzle being mounted in the passage at a front portion of the cleaner. The liquid recovery system includes a air-liquid separator fluidly connected with a suction nozzle and a suction source for drawing liquid and debris into the air-liquid separator, and a recovery tank releasably mounted to the air-liquid separator for collecting recovered liquid. The agitation brush assembly is mounted in a lower forward portion of the cleaner for contact with a surface being cleaned.

摘要： A portable surface cleaning apparatus including a base module for movement along a surface, an upright handle pivotally attached to the base module, a liquid dispensing system including a flexible bladder defining a fluid supply chamber for holding a supply of cleaning fluid, a fluid recovery system including a tank on the base module having a fluid recovery chamber for holding recovered fluid and housing the flexible bladder, and a fluid passageway between the fluid supply chamber and the recovery chamber, whereby the recovery chamber is in fluid communication with the fluid supply chamber and the pressure in the flexible bladder is equalized with the pressure in the tank as the cleaning fluid is dispensed from the supply chamber and the dirty liquid is collected in the recovery chamber. In a further embodiment the tank has an outlet opening in a bottom portion thereof and a drain plug is removably mounted in the outlet opening. In another embodiment a lid mounted on the tank defines an expansion chamber having an inlet opening, an outlet passage, and first and second diverters against which the working air flow reverses direction twice between the inlet opening of the expansion chamber and the tank. In another embodiment the working air conduit includes a manual actuator knob having an over-center linkage mechanism connected to a conversion valve for movement between first and second positions and thereby selectively moving the conversion valve between open and closed positions, whereby fluid communication between the tank and the suction nozzle is selectively opened and closed. In a further embodiment, a flow indicator is mounted to the base module and has a visibility window observable to a user and the flow indicator is disposed in the fluid supply conduit and is responsive to the flow of fluid through the fluid supply conduit to visually indicate the flow of fluid through the supply conduit to the user. Another embodiment includes a pump primer connected to the pump and having a housing defining a priming chamber with a valved opening connected to the vacuum source, an inlet opening connected to the fluid supply chamber, and an outlet opening connected to an inlet for the pump. A further embodiment includes a first mechanical connector extending between the motor drive shaft and the pump drive shaft, whereby the motor drives both the agitation brush and the pump. In a further embodiment, the base module includes an upper housing portion and a lower housing portion and an upright handle is pivotably mounted to the rear portion of the base module through at least one bearing for rotatable reception in the housing. In another embodiment, an elevator assembly is reciprocally mounted to the base module and movable in response to movement of the upright handle from an operative position to the upright position for upwardly pivoting a pivot arm mounting an agitation brush.

摘要： A sustainable system for refilling a pressurized fluid dispenser comprises a container body having a first fluid dispenser that includes a valved opening, a pouch mounted within the container body for storing a fluid composition and fluidly coupled with the valved opening of the container for dispensing the contents of the pouch and a fluid refill system. A pressurized gas can be provided between the pouch and the container body for pressurizing the contents of the pouch. The fluid refill system includes at least one reservoir having a fluid composition therein and a second fluid dispenser having a fitting that is adapted to dispense the fluid composition from the at least one reservoir into the pouch. A controller can be programmed to respond to input signals to position the container with the fluid refill system and to dispense the fluid composition under pressure into the pouch.

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.
