摘要： A carpet extractor includes a base assembly (A) with a two part base housing (10). Upper (22) and lower portions (24,528) of the base housing define a socket (100), for receiving a cleaning fluid recovery tank (120,552), and a chamber (50), rearward of the socket, for receiving a suction fan (82,540) and associated motor (80,542). The chamber includes front (78,544) and rear compartments (546,76) for receiving the suction fan and motor, respectively. The lower portion (22,528) of the base housing defines a first pocket or indentation (70,550) for receiving a motor (68,548) for driving a rotating brushroll (60) and a second pocket (532) for receiving a solution supply pump (520) which selectively supplies pressurized cleaning fluid to a spray bar (526) and a remote distributor (614). The pocket and indentation are positioned rearward of the socket, and generally beneath a forward end of the chamber. The location of the fan, fan motor, pump, and brushroll motor behind the recovery tank socket provides for the accommodation of a large capacity recovery tank, while maintaining a low-profile base assembly.

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： A wet dry cannister vacuum having an upper and lower chamber separated by an intermediate wall. A blower (1) in the upper chamber providing a low and high pressure head communicating with respectively with low and high pressure compartments. A valve (2) opening from the low pressure compartment through the intermediate wall to the lower chamber. Another valve (8) opening from the high pressure compartment through the intermediate wall into the lower chamber. A water reservoir in the bottom of the lower chamber. A duct (15) opens on one end near the bottom of the lower chamber and on the other end to ambient air pressure. In operation, before wet or loose dry material is vacuumed, a small amount of water is introduced into the lower chamber by length of flexible hose being attached to the duct (15) and to a water source on the other. After priming, an attachment for cleaning may be attached to the hose, such as a shampoo wand (25). When refuse water accumulates in the reservoir to a certain level, a float (13) rises to shut off the blower automatically when a predetermined amount has been accumulated. To empty the reservoir, the space above the reservoir in the lower chamber is connected to the high pressure head by reversing the valving in the upper chamber. The duct (15) becomes an discharge pipe pumping out the refuse water to a drain after removing the attachment on the hose.

摘要： A pump has a housing defining a pump chamber and having a shaft opening. An impeller shaft extends through the shaft opening and is sized to define a gap between the impeller shaft and the shaft opening. An impeller is attached to the shaft inside the pump chamber. The impeller includes a first set of impeller blades for transporting fluid through the pump chamber and a second set of impeller blades for creating a pressure force which pushes fluid away from the shaft opening. The pump with sealless shaft prevents fluid from leaking through the gap, and therefore is particularly suited for use in a tank-type vacuum cleaner capable of collecting both dry material and fluid. The gap is used in such an application to prime the pump, thereby discharging fluid collected in the tank.

摘要： A vacuum cleaner has an electric motor driving an air impeller for creating suction and a pump impeller which is located in the tank and draws liquid material from the bottom of the tank and expels it from the tank. The vacuum cleaner may have an electrical or mechanical shut-off apparatus which turns off the electric motor if the water level in the tank is too high. The shut-off switch may be bypassed by a user to allow the motor to continue driving the pump impeller to remove liquid from the tank.

摘要： A hand-held portable wet/dry vacuum comprising a cleaning fluid tank, a motor housing and a dirty fluid tank. The cleaning fluid tank is selectively mounted on the motor housing. A siphon, which is controlled by an actuator, is located in the cleaning fluid tank. The dirty fluid tank is selectively mounted on the motor housing in spaced relation to the cleaning fluid tank. The motor housing houses an air driven turbine and a suction fan and motor assembly. A suction nozzle is located at a first end of the wet/dry vacuum. An air passageway extends from the suction nozzle to the suction fan and motor. The turbine communicates with the air passageway. The housing further comprises at least one air inlet to allow air to pass to the turbine. A brush is operably connected to the turbine via a gear train. A rotational axis of the brush is angled so that a portion of the brush contacts a surface to be cleaned. At least one air inlet is found in a wall of the motor housing for allowing cooling air into the motor housing. A valve is located in the air passageway and switches airflow between the turbine and the suction nozzle. Alternatively, an electric motor is used in lieu of the turbine to power the brush.

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. Supply tanks are removably mounted to the handle or base while a recovery tank is removably mounted to the handle or base. An outlet in each supply tank includes a valve to close the outlet when the supply tank is removed from the base. A protrusion in a bottom surface of the supply tank defines a measuring volume for concentrated cleaning solution and is further adapted to stabilize the supply tank in the base or handle. The supply tank also includes an aperture through a lower portion selectively closed by a drain plug. A conduit connecting each supply tank to a dispensing nozzle includes a check valve restricting fluid flow to a direction from the tank and to the nozzle. Also, a float assembly in the recovery tank includes a first end for covering an air exit from the recovery tank and a second end, which is buoyant and elevated by the rising recovered fluid in the tank, for raising the first end to cover the air exit.
