Abstract: 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.

Abstract: Spray nozzles are frequently used for distributing pressurized fluid onto a surface to be cleaned. The spray nozzle according to the invention is ideally suited for use with a water extraction cleaning machine and for distributing a fan-shaped spray pattern onto the surface to be cleaned. The spray nozzle includes a nozzle body with a fluid flow path extending therethrough. An arcuate deflector plate is provided a spaced distance from the outlet of the fluid flow path. A pinpoint spray of pressurized cleaning solution is directed onto the downwardly and outwardly extending concave deflector surface for creating a fan-shaped spray pattern. The contour of the concave deflector surface can comprise a variety of concave surfaces such as a cylindrical surface, a parabolic surface and a hyperbolic surface. The incorporation of a concave deflector surface is ideally suited for containing and controlling the spray pattern for increasing fluid flow rates and pressures.

Abstract: A vacuum cleaner has a cleaning powder distribution system and an actuator connected to the powder distribution system for selectively dispensing powder from the powder distribution system to soiled spots on a floor surface. In addition, a cleaning fluid distribution system is adapted to selectively distribute a liquid cleaning solution to the soiled spot. A propellant, in the form of an aerosol or compressed gas can be used to distribute the cleaning powder to the floor. A method of cleaning a spot on a surface comprises applying a selected volume of fluid cleaning solution to a selected area on the surface to be cleaned, applying a selected amount of cleaning powder to the selected area and extracting the applied cleaning solution and cleaning powder from the selected area on the surface to be cleaned.

Abstract: According to the invention, a surface cleaning device comprises an electrolytic cell for generating bleach for use with a cleaning pad. The electrolytic cell is in fluid communication with the cleaning pad for delivering bleach to a surface to be cleaned. According to another embodiment of the invention, the surface cleaning device is a hand-held cleaning device capable of selectively generating bleach at the request of a user directly in the cleaning pad. A sufficient amount of bleach for cleaning a surface can be generated within the electrolytic cell at the request of a user, eliminating the need for storing and transporting large quantities of bleach.
