This invention relates to cleaning and floor care machines, and more particularly, to multi-functional cleaning and floor care machines.
Floors can be difficult and expensive to maintain. If not cared for properly, they not only become unsightly, they can drive customers away, cause slip and fall accidents, and even become a health hazard. Unfortunately, traditional mopping can make matters worse. Mopping is slow, ineffective, and even potentially dangerous—leaving floors slippery, wet, and with very few of the soils and biopollutants removed. Grouted floors are even trickier. In fact, during mopping, grout lines actually “squeegee” soil and soap scum from mops. When the water evaporates, soils, mineral deposits, soap scum, and potentially harmful biopollutants are left to penetrate and coat the porous grout. Grout lines that started out light gray or white soon become stained and darkened.
Traditional cleaning tools, like mops and wipes, remove very few soils, germs and other indoor pollutants. In fact, studies show they often simply spread them around. Then, workers end up crawling around on their hands and knees wiping soiled surfaces and fixtures by hand.
In one aspect of the invention, a multi-functional cleaning and floor care system may have a reservoir defining an interior space operable to hold a fresh cleaning liquid, a vacuum recovery tank, a vacuum motor assembly fluidly connected to the vacuum recovery tank; and a wheeled chassis configured to support at least one of the fresh liquid reservoir and the vacuum recovery tank. The system also may have a spigot fluidly connected to the reservoir interior space, with the spigot adjustable between a fully open position and a fully closed position, whereby when the reservoir contains a fresh cleaning liquid, a user may regulate the flow of the fresh cleaning liquid from the reservoir through the spigot by adjusting the spigot. In addition, the system may have: a liquid spreader assembly connected to at least one of the fresh liquid reservoir, the wet 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 wet vacuum assembly, and the wheeled chassis, the squeegee head assembly fluidly connectable to the vacuum recovery tank. The liquid spreader assembly may be operable to spread on a floor surface at least a portion of the fresh cleaning liquid from the reservoir, and the squeegee head assembly may be operable to vacuum at least a portion of the liquid on the floor surface into the vacuum recovery tank.

As seen in
The liquid spreader assembly 18 has a frame 84, a spreader pad 86 releasably attached to a bottom surface of the frame, a pair of connecting arms 88, 90 (see, e.g.,
Depending on the particular upper portion female snap selected, a user may put the liquid spreader assembly 18 in a down position (see, e.g.,
The squeegee head assembly 20 has a frame assembly 96 (see, e.g.,
In addition, the squeegee head assembly 20 has a plow member 114, 116 (see, e.g.,
One end of each connecting arm 98, 100 is attached to an upper surface of the squeegee head assembly frame 104; and the other end is releasably and rotatably attached to the crossbar 80. As best seen in
Depending on the particular upper portion female snap selected, a user may put the squeegee head assembly 20 in a down position (see, e.g.,
In use, the user may open the reservoir spigot and turn on the wet-dry vacuum. Then the user may pull or push the multi-functional cleaning and floor care system (e.g., in a serpentine pattern) over the floor surface to be cleaned. As the user pulls or pushes the system along, cleaning solution is dispensed, spread, and vacuumed in one easy step.
The modular design of the multi-functional cleaning and floor care system allows for quick and easy part replacement and changing from one cleaning mode to another. The design makes this process as simple as snapping on and snapping off. The modular design also allows the user to shift quickly and easily between a spread-only mode, a vacuum-only mode, and a spread-and-vacuum mode.
The connecting arms are designed so that, if a user catches part of the liquid spreader assembly or squeegee head assembly on an obstacle (e.g., a corner of a wall or heavy table), the connecting arms may detach (i.e., snap off) from the hitch—thereby preventing the liquid spreader assembly and the squeegee head assembly from breaking. Also, the connecting arms are designed to have some degree of twist; in this fashion, if either end of the squeegee head assembly frame brushes up against an obstacle, the squeegee head assembly can flex to get around the obstacle.
The connecting arms are free to rotate around the hitch. This allows the arms to be rotated and stored in the upward-most position. In the upward position, the user can easily have access to the spreader pad (e.g., a microfiber pad) for replacement. The rigid design of the connecting arms allows the user to either pull or push the floor care system. This allows easy maneuvering into tight spaces and backing into corners or edges. If needed or desired in order to clean an edge or alcove, the user can disconnect the vacuum hose from the floor tool assembly and quickly attach the vac hose to a vacuum wand for trimming and cleaning these hard to reach areas.
The wet-dry vacuum of the multi-functional cleaning and floor care system may be powered in any suitable way. For example, the vacuum motor assembly may be connected to an electrical outlet (e.g., a wall outlet) via a power cord. Alternatively, the system may include a battery or the like.
In use, the multi-functional cleaning and floor care system may be used for a wide variety of floor care needs. For example, the system may be used to apply a general-purpose cleaning solution, a stripping solution, a disinfectant, or a degreasing solution. The system may be used, e.g., for daily floor cleaning, stripping floors, and finishing floors. Also, the system may be used in any of a number of locations and facilities, e.g., hallways, lobbies, cafeterias, gymnasiums, warehousing, shop floors, healthcare, and retail.
In use, a multi-functional cleaning and floor care system, in accordance with the principles of the invention, may be operated in a number of different configurations and ways—determined largely by the particular cleaning- or other floor care-activity to be performed.
For example, for general or routine cleaning, a user may fill the reservoir with cleaning solution, put the liquid spreader assembly and the squeegee head assembly in the down position, open the spigot to dispense cleaning solution, turn on the vacuum motor, and start cleaning. If extra dwell time is desired—for example, for heavy soil situations or for disinfection purposes—the user can simply raise the squeegee head assembly to the up position, and leave the liquid spreader assembly in place in the down position. In this manner, the system will disperse a thin uniform layer of solution as it leaves the spigot. Then, if desired, after a sufficient amount of dwell time, the user may simply lower the squeegee head assembly to the down position and vacuum up the solution.
If a user wants to apply and remove a floor stripper solution, the system allows them to do so in a highly productive manner. For example, to apply the solution, the user may move the four-bend handle to the front of the reservoir assembly, move the squeegee head assembly to the up position, keep the liquid spreader assembly in the down position, open the spigot, and pull the system (i.e., with the liquid spreader assembly trailing behind the spigot). To vacuum up the stripper solution, the user may remove the liquid spreader assembly, lower the squeegee head assembly to the down position, turn on the vacuum motor, and push the system (i.e., with the squeegee head assembly and the back of the liquid reservoir now leading (i.e., the reservoir back now being at the front), and the front of the liquid reservoir now trailing behind the back. In this way, the user does not walk through the stripper solution—either in applying or removing the solution.

And as noted above, to facilitate understanding of the invention, like reference numbers are used for like elements across the various embodiments.

In an alternate embodiment (not shown), the liquid spreader assembly and the squeegee head assembly may be fastened to a Kaivac No-Touch Cleaning® machine commercially available from Kaivac, Inc. of Hamilton Ohio. As needed, a bracket may be mounted to the back of a Kaivac No-Touch Cleaning® machine so as to locate the hitch at a suitable height above the floor. A quick disconnect fitting and spray wand may be mounted to the bracket, so that the spray line of the No-Touch Cleaning® machine may be attached to the spray wand. The spray wand may have a suitably sized nozzle such that the cleaning solution from the No-Touch Cleaning® machine may be dispensed at a proper location relative to the liquid spreader assembly and the squeegee head assembly (e.g., in front of both assemblies).
The multi-functional cleaning and floor care system of the present invention may be made using any suitable material(s) and manufacturing technique(s). For example, if desired, the reservoir may be made of polypropylene using injection molding, and the vacuum recovery tank may be made of polyethylene via rotational molding. Also, if desired, the vacuum motor assembly may have the following specifications: 85 inches of lift; 60 cfm; 75 decibels; for the U.S., 110 Volts, 60 Hz, 10 amps; for Universal, 100-240 Volts, 50-60 Hz, 5.5 amps; and heavy duty two-stage vacuum motor.
