A multi-use power foot suitable for use for both dry vacuum cleaning and water extraction procedures is disclosed. The power foot has a dry suction chamber in fluid communication with an outlet and a water suction chamber in fluid communication with the outlet. A diverter valve member is mounted within the housing to selectively restrict the air flow from one of the chambers to the outlet. A rotating brush is mounted in the opening of the dry suction chamber to agitate the surface to be cleaned in both the dry vacuum cleaning and water extraction modes. Spray nozzles are mounted to the underside of the power foot to direct a water based cleaning solution to the surface to be cleaned.

Combination vacuum cleaner and water extractor power foot

The water extraction machine according to the invention provides a quick connect system for mounting one end of a solution tube and vacuum hose to the water extraction machine housing and a simple and efficient means for conveying solution from the housing to a cleaning tool. One end of the vacuum hose and solution tube are received in a cuff member which is adapted to be received in the machine housing by a simple press fit interconnection. The cuff member provides a single connection for both the vacuum hose and the solution hose to the machine housing. The other end of the vacuum hose and solution tube are received in a clam shell grip tube handle which is in turn mounted to an extruded dual chamber wand. A first longitudinal chamber in the wand conveys vacuum through the wand and the second longitudinal channel conveys cleaning solution from the grip tube to the cleaning tool. The structure for the water extraction machine according to the invention results in a more efficient system for conveying cleaning solution and vacuum to and from the machine housing and cleaning tool. In addition, the system is adapted for quick assembly and disassembly by the user.

Hose and wand assembly for water extraction machine

A switch and connector for selectively creating an electrical circuit between a motor mounted in a power foot and a combination vacuum cleaning/water extraction machine is disclosed. The motor mounted in the power foot drives an agitation member rotatively mounted in the power foot. The power foot is inter-connected to the housing of the machine through a rigid wand, a grip tube and a flexible hose. A pneumatic switch is mounted in the electrical circuit between the source of electricity and the power foot motor. A bladder is mounted to the grip tube and in fluid communication with the pneumatic switch through a conduit. The bladder is constructed such that the pneumatic switch cannot be activated to create a complete electrical circuit between the source of electricity and the power foot motor unless the grip tube and wand are properly assembled.

Cleaning machine and control switch therefor

A vacuum extractor has a tank assembly including an outer tank and a coaxial inner tank. The inner tank has an open top which is reversibly closed by a cover assembly which includes a vacuum source and a liquid pump. The cover assembly also includes a hose connection in communication with said inner tank and said vacuum source enabling said inner tank to receive either wet or dry materials. The outer tank is substantially closed having an input port closed by a closure member configured in the form of a measuring cup. The outer tank is used for containing a cleaning material which can be accessed through a hose which passes through an aperture in the outer wall of the tank. The hose has an external connector for supplying cleaning material to the liquid pump in the cover assembly which, in turn, supplies the cleaning material to a cleaning tool. The unit is supported by casters which are recessed into the bottom of the tank assembly. A pair of opposed caster recesses are shaped to provide handholds to assist in emptying the separate tanks. The inner tank can be emptied by pouring in a first direction while both inner and outer tanks can be emptied simultaneously by pouring in a second direction opposite to the first direction.

Self-contained, compact vacuum/extractor

A liquid extraction surface cleaning apparatus having a cleaning solution tank and a recovery tank held in a floor-supported carriage with the tanks having sidewalls extending above the carriage. A housing which contains a suction fan, a suction chamber, a suction inlet connecting with the chamber and a water and air separator sits on top of the tanks with the suction chamber over the recovery tank. The housing is latched to the carriage capturing the tanks. A cleaning solution dispensing means extracts cleaning solution from the solution tank. Each tank has a pivotally connected handle and the cleaning solution tank has a chemical dispensing tray integral to its handle.

A fluid flow control valve according to the invention includes a base, a valve member, a trigger member and attachment means for attaching the trigger member to the valve member. The base includes a generally horizontal throat and a flange having an upwardly facing surface. The valve member has a stem, a flow level establishing member associated with the stem and biasing means for biasing the stem in a direction opposite to that in which the throat extends. The trigger member includes a pin configured to rotate against an inner end portion of the throat, a flange having a downwardly facing surface and an actuating portion. The biasing means acts in a direction through the attachment means to pull the actuating portion downwardly such that the flanges engage in order to retain the pin in the throat. In this manner, the valve may be assembled without the use of fasteners.

The present invention is a suction hose clip for connecting an accessory hose, an accessory cable or the like to the suction hose of a vacuum cleaning device. The clip is generally ring-shaped with an open side defining two opposing ends. The clip has an accessory receiving area positioned generally opposite to the open side. Oppositely facing hook portions are provided at the two opposing ends and engage with each other to provide a hook over hook closure to close the clip around a suction hose. A rib projects from the inner wall of the clip to engage the corrugated surface of a suction hose and keep the clip from sliding along the length of the suction hose.

A cleaning apparatus which is of a compact construction to facilitate easy manipulation and portability includes a housing enclosing a fluid pump and a vacuum fan and mounting upon opposite sides a recovery tank and a stowage panel. The stowage panel is adapted to stow the flexible wand having a nozzle when not in use. Also, the high voltage motor driving the vacuum pump is adapted to also act as half of a transformer in order to pick off the lower voltage needed for the low voltage motor driving the fluid pump.

Cleaning apparatus

A liquid extraction surface cleaning apparatus has an upwardly opening recovery tank and a top for the tank which contains a suction fan having a suction inlet opening into the tank. A wand connects to a source of cleaning liquid and has a dispensing and pickup head that deposits liquid on the surface to be cleaned in response to actuation of a control valve and picks up dirty fluid. A water and air separator has an arcuate surface transverse of the flow path of the air and spent liquid which gently separates them into separate streams by diverting the cleaning liquid laterally away from the air stream. A shutoff valve for preventing recovered liquid in the tank from entering the suction fan is mounted in the recovery tank rather than to the suction inlet to avoid dripping dirty liquid onto the floor when the cover is removed. A handle is mounted internal the tank and additionally serves to strengthen the tank sidewalls.
