Abstract: A walk-behind floor microscrubber apparatus. The microscrubber includes as main subassemblies an upright handle assembly pivotally connected to a base assembly. The handle assembly includes components for recovering a cleaning solution applied to the floor during cleaning operations. The base assembly houses electrically powered motors for driving scrubbing brushes, and a clean solution reservoir. Spent cleaning solution applied to the floor is sucked to a recovery tank on the handle assembly. The microscrubber has features for avoiding vacuum motor flooding, including a specially-shaped recovery tank. Chambers in the recovery tank capture used cleaning solution when the handle assembly is tilted, thereby reducing the likelihood of solution travelling back to the vacuum motor. The microscrubber also has an exoskeleton reserve tank in the handle assembly.

Abstract: An upright walk-behind microscrubber apparatus including a handle assembly connected to a base assembly, and featuring an improved handle function. The handle assembly is manipulated by the user to operate the apparatus. The apparatus provides a releasable, lockable, joint assembly that connects the handle assembly to the base assembly, whereby the handle assembly is pivotally connected to the base assembly. The joint assembly permits the handle assembly to be disposed in a fully released configuration in which the handle assembly is freely pivotal relative to the base assembly, or in a fully locked position in which the handle assembly is temporarily locked in an upright orientation. The joint assembly permits the base assembly to be released to a use position generally parallel to the floor, or releasably locked in a storage position generally parallel to the handle assembly but with the base assembly's scrubbing brushes removed from the floor.

Abstract: A portable apparatus including a hose and wand and an attachment device for storing the hose in a coiled condition and for supporting the wand in a vertical position above the surface on which the apparatus rests.

Abstract: The vacuum extractor of the present invention is a self contained system for delivery of hot cleaning solution to a surface and vacuum removal of the spent solution either simultaneous with its application or at a later time through a vacuum system which deposits the spent cleaning solution in an upper housing. The extractor is configured to dump the cleaning solution from an upper housing which may be pivotally tipped upwardly from the front to enhance the draining of spent solution. The rear of the extractor of the present invention is configured to enable the extractor to be back up to and located adjacent a toilet bowl. The upper housing containing the spent solution is high enough to be pivoted over the toilet bowl and emptied, while still pivotally attached to the lower housing. The dump valve is positioned to be protected from damage from bumping surrounding structure.

Abstract: An air mover which allows for both side-by-side and coaxial stacking. An air mover is essentially composed of substantially a cylindrical fan or motor housing with an air exhaust nozzle extending tangentially therefrom. The side-by-side stacking arrangement includes the interlocking of the stacking register of the handle of the air mover with the underside of the accessory flange at the distal end of the nozzle. The handle snugly nests within the space formed by the nozzle as it extends tangentially from the motor housing. The coaxial stacking involves the interlocking of a tab on the nozzle and a circular projection on one planar surface of the air mover with a slot and circular depression on the opposite planar of another air mover. The diameter of the circular depression being greater than the diameter of the circular projection and the slot being sized to receive the tab. Alone or in combination, the interlocking systems provide for compact storage and transportation.
