Abstract:

In one embodiment, a cleaning cart system of the invention includes a reservoir assembly, an upwardly extending handle releasably connectable to the reservoir assembly, and at least two modular cleaning bins. The reservoir assembly includes a liquid reservoir and an integral wheeled chassis. The liquid reservoir includes a circumferential sidewall and an integral top wall, with the top wall including a plurality of openings. The two modular cleaning bins may be: positioned within the liquid reservoir; positioned on the liquid reservoir top wall with a leg of one bin positioned in one of the top-wall openings, and with a leg of the other bin positioned in another of the top-wall plurality of openings; and alternatively releasably interconnected to one another in a side-by-side orientation, with one of the bins supported on the upwardly extending handle by one or more of a plurality of handle brackets.

International Classification:

A47L 5/00
A47L 9/00

US Classification:

015326000

Abstract:

A cleaning machine with a sound suppression system may include a waste recovery tank and a centrifugal-bypass vacuum motor assembly. The vacuum motor assembly may include a working-air flow path and a separate motor-ventilating-air flow path, with the working-air flow path including a working-air inlet and a working-air outlet. The working-air inlet may be fluidly connectable to the waste recovery tank, whereby the vacuum motor assembly may enable a soil-containing fluid to be vacuumed into the waste recovery tank. The cleaning machine also may include a sound-suppression hood that covers at least a part of the vacuum motor assembly. Alternatively, or in addition to the sound-suppression hood, the cleaning machine may include a first muffler assembly and a second muffler assembly. The first muffler assembly may be fluidly connected to the working-air outlet; and the second muffler assembly may be fluidly connected to the first muffler assembly. In this fashion, sound produced by the vacuum motor assembly may be suppressed.

International Classification:

A47L 7/00

US Classification:

15320

Abstract:

An embodiment of the cleaning and floor care system has a reservoir assembly and a wet/dry vacuum assembly. The reservoir assembly has a wheeled chassis and an integral reservoir. The reservoir has a circumferential sidewall and an upper end. The reservoir defines an interior space for holding a fresh cleaning liquid; and the reservoir upper end defines an opening. The reservoir assembly further has a spigot fluidly connected to the reservoir interior space, with the spigot having a valve adjustable between a fully open and a fully closed position. The vacuum assembly has a recovery tank and a motor assembly. The vacuum assembly is removably positionable on top of the reservoir, and is transportable on the reservoir. Each of the reservoir assembly and the vacuum assembly is operable both when the vacuum assembly is positioned on top of the reservoir, and when the vacuum assembly is separated from the reservoir.

International Classification:

A47L 11/30

US Classification:

15320

Abstract:

A multi-functional cleaning and floor care system may have: a fresh liquid reservoir; a vacuum assembly including a vacuum recovery tank and a vacuum motor assembly; a wheeled chassis configured to support at least one of the fresh liquid reservoir and the vacuum recovery tank; and a spigot fluidly connected to the fresh liquid reservoir, with the spigot adjustable between a fully open position and a fully closed position. The system also may have: a liquid spreader assembly connected to at least one of the fresh liquid reservoir, the vacuum assembly, and the wheeled chassis, with the liquid spreader assembly including a frame and a spreader pad; and a squeegee head assembly connected to at least one of the fresh liquid reservoir, the vacuum assembly, and the wheeled chassis, with the squeegee head assembly fluidly connectable to the vacuum recovery tank.

International Classification:

A47L 9/06

US Classification:

15401

Abstract:

A particular wide-area vacuum/squeegee-head floor cleaning tool, in accordance with the principles of the invention, includes: an elongated frame including a top, a front, a back, a first end, a second end, and a soil uptake opening positioned between the first and second ends; at least one squeegee blade at the front and extending between the first and second ends; at least one squeegee blade at the back and extending between the first and second ends; a first wheel at the first end; a second wheel at the second end; and a third wheel at the soil uptake opening. The first, second, and third wheels are constructed and arranged to support the elongated frame above a floor surface when the squeegee blades at the front and back are in contact with the floor surface in a deflected orientation and vacuum suction is applied to the floor cleaning tool by the vacuum source.
