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, a multi-functional cleaning and floor care system, in accordance with the principles of the invention, has a reservoir assembly, a wet/dry vacuum assembly, and a handle in the form of a four-bend handle. The reservoir assembly has a wheeled chassis and a reservoir integral with the wheeled chassis. The reservoir has a circumferential sidewall and an upper end. The reservoir defines an interior space operable 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 that is adjustable between a fully open position and a fully closed position; in this fashion, 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 valve. The wet/dry vacuum assembly is removably positioned on top of the reservoir, with the wet/dry vacuum assembly having a vacuum recovery tank and a vacuum motor assembly fluidly connected to the vacuum recovery tank. The four-bend handle is removably connected to the reservoir. A strap assembly on each side of the vacuum recovery tank releasably connects the wet/dry vacuum assembly to the four-bend handle. The wet/dry vacuum assembly is transportable on the reservoir. In addition, each of the reservoir assembly and the wet/dry vacuum assembly is operable both when the wet/dry vacuum assembly is positioned on top of the reservoir, and when the wet/dry vacuum assembly is separated from the reservoir.
The multi-functional cleaning and floor care system provides numerous advantages. For example, a user may open the spigot and apply fresh cleaning solution to a floor, spread and lightly brush the solution into grout lines, and then vacuum the soils and liquid away. This results in a floor that is both clean and dry. The process is significantly better, faster, and safer than cleaning with a mop. If desired, the user may operate the wet/dry vacuum assembly of the invention separate and apart from the reservoir assembly. For example, the wet/dry vacuum assembly may be used for picking up spills, detail cleaning, job sue cleanup, flood recovery, or for vehicle and equipment detailing.
These and other advantages of the present invention will be apparent from the accompanying drawings and description of the drawings.
The accompanying drawings, which are a part of this specification, illustrate embodiments of the invention. And together with the general description of the invention given above, and the detailed description of the drawings given below, the accompanying drawings explain the principles of the invention.

The multi-functional cleaning and floor care system 10 provides numerous benefits. For example, a user may open the spigot and apply fresh cleaning solution to a floor, spread and lightly brush the solution into grout lines, and then vacuum the soils and liquid away. This results in a floor that is both clean and dry. The process is significantly better, faster, and safer than cleaning with a mop. If desired, the user may operate the wet/dry vacuum assembly of the invention separate and apart from the reservoir assembly. For example, the wet/dry vacuum assembly may be used for picking up spills, detail cleaning, job site cleanup, flood recovery, or for vehicle and equipment detailing.
The particular reservoir assembly shown in the Figures is substantially similar to the reservoir assembly disclosed in commonly-owned U.S. patent application Ser. No, 12/660,935, entitled “Cleaning Cart Systems” and filed on Mar. 4, 2010. The entire disclosure of U.S. patent application Ser. No. 12/660,935 is incorporated into this patent document by reference.
The reservoir assembly has a reservoir and a wheeled chassis integral with the reservoir. The reservoir has a circumferential sidewall and a bottom wall—with the circumferential sidewall including a front wall, a back wall, a left sidewall, and a right sidewall. Together, these walls define the reservoir and the interior space within the reservoir—a reservoir capable of holding a cleaning solution or other liquid, or alternatively, any of a number of different cleaning supplies. The circumferential sidewall also has an upper end and a top wall at the upper end. The top wall is integral with the circumferential sidewall, and extends outward away from the circumferential sidewall and reservoir interior space. In addition, the top wall has a number of openings and recessed areas, as discussed in further detail below.
The chassis includes the structure that supports the wheels. The reservoir assembly has four wheels—two swivel casters at the front, and two fixed-axle wheels at the back. At the front, the chassis includes a reinforced post or leg at the front lower-left corner, and a reinforced post or leg at the front lower-right corner. Each of these legs includes a cylindrical bore for receiving the post of the corresponding caster. At the back, the chassis includes a wheel frame at the back lower-left corner, and a wheel frame at the back lower-right corner.
The reservoir assembly also has a spigot fluidly connected to the reservoir, and an extension arm rearward of the back wall. The extension arm is connected to the spigot and includes an upwardly extending section. A user may operate the spigot between a fully open position and a fully closed position by rotating the extension arm. The spigot makes the system ideal for applying stripper, floor finish, gym finish, or fresh cleaning solution onto a surface in a controlled precise manner. If desired, the spigot also may be used to drain liquid from the reservoir. Additional aspects of the spigot, extension arm, and related features are discussed in further detail below.
As mentioned briefly above, the reservoir has a top wall. The top wall also is continuous—extending all the way around the reservoir at the circumferential sidewall. In alternate embodiments, however, the top wall does not have to be continuous, and does not have to extend all the way around the reservoir. For example, the top wall may be discontinuous, or may comprise one or more discrete members or segments.
Also as noted briefly above, the top wall has a number of openings and recessed areas—openings and recesses that may be used in various ways. The top wall has a front section, a back section, a left section, and a right section—with each top wall section integral with an adjacent top wall section. Moving from the back of the reservoir to the front, the top wall left section has a cylindrical bore, a rectangular opening, a pair of circular openings, another cylindrical bore, an additional circular opening, and an elongated channel or recessed area—the channel located at the front left corner of the top wall, and formed in conjunction with the top wall front section. The top wall right section is essentially the mirror image of the top wall left section—including a cylindrical bore, a rectangular opening, a pair of circular openings, another cylindrical bore, an additional circular opening, and an elongated channel or recessed area—with the channel located at the front right corner of the top wall, and formed in conjunction with the top wall front section. Each of these top wall right section features is positioned directly across the reservoir from its corresponding top wall left section feature. The top wall front section has a cylindrical bore at the midpoint of the section. Each of the cylindrical bores has a bottom wall, with the bottom wall including an opening for drainage.
As mentioned in the preceding paragraph, each of these top wall features may be used in a number of different ways—which contributes to the flexibility of the cleaning cart system. One leg of the four-bend handle is inserted in the cylindrical bore, and the other leg is inserted in the cylindrical bore.
The elongated channels at the front left and front right corners of the top wall are configured to assist in guiding a liquid from the reservoir when the reservoir contains a liquid and a user chooses to drain the liquid via either the front left corner or the front right corner of the top wall. A user may use the downwardly facing exterior surface of a channel and/or an adjacent exterior rounded corner edge surface (formed where the reservoir front wall meets the corresponding reservoir sidewall) as a pivoting surface, e.g., against the rim of a toilet, when draining liquid from the reservoir via the left or right front corner.
The wet/dry vacuum assembly now is described in greater detail. As noted above, the wet/dry vacuum assembly has a vacuum recovery tank and a vacuum motor assembly fluidly connected to the vacuum recovery tank. The vacuum motor assembly is positioned on top of the vacuum recovery tank, and is releasably fastened to the vacuum recovery tank with latches. The vacuum recovery tank has a top wall, a bottom wall, a front wall, a back wall, a left sidewall, and a right sidewall. A suction inlet is located toward the top of the front wall; and a discharge outlet is located at the bottom of the front wall. Four swivel caster wheels extend downward from the bottom wall, providing the wet/dry vacuum assembly with easy 360-degree mobility.
If desired, the vacuum motor assembly may have the following specifications: 114-130 inches of water lift; 60-300 CFM; and 85-300 MPH blow. The wet/dry vac tank may have a capacity of about 11.5 gallons; and the wet/dry vac assembly may have 25-50 feet of vacuum hose. If desired, the vacuum motor assembly may have the following specifications: Vac Tank: 11.5 Gallons (43.5 l); Dump/Drain Hose: 22 inches (56 cm) long; Vac Tank Cleanout: 100% via Dump/Drain Hose; Vac CFM: 60 cfm (1700 l/min); Blow Feature: 85 mph (137 km/h); and Vac Motor Lift: 114 inches -dead head (290 cm). Other aspects of the wet/dry vacuum assembly may include: a 50 foot slinky-style vacuum hose; and a 15 foot retractable electrical cord; and the vacuum motor being a heavy duty two-stage vacuum motor.

The reservoir has a lip that extends laterally from the reservoir left sidewall, the lip in the form of the left section of the top wall. The reservoir also has a lip that extends laterally from the reservoir right sidewall, the lip in the form of the right section of the top wall. The reservoir support surface comprises a portion of each of the top wall left section and the top wall right section.
The vacuum recovery tank support surface comprises a first support surface extending between the front and back walls of the tank, and a second support surface also extending between the front and back walls of the tank. Where the tank left sidewall and bottom wall meet, there is a recess or shelf extending between the front and back walls of the tank; the first support surface is in the form of a wall portion at this left recess or shelf. Where the tank right sidewall and bottom wall meet, there is a recess or shelf extending between the front and back walls of the tank; the second support surface is in the form of a wall portion at this right recess or shelf. When the wet/dry vacuum assembly is removably positioned on the reservoir, a portion of the reservoir top wall left section supports part of the wall portion of the left recess or shelf; and a portion of the reservoir top wall right section supports part of the wall portion of the right recess or shelf.
The wet/dry vacuum assembly may be removably positioned at a number of locations along the length of the reservoir. The reservoir includes a front, a back, and a length that extends from the front to the back. And the vacuum recovery tank includes a length that extends from the vacuum recovery tank front to the vacuum recovery tank back. The reservoir length is greater than the vacuum recovery tank length; and therefore, the wet vacuum assembly may be removably positioned at a number of locations along the length of the reservoir.

A user may apply automatically diluted cleaning solution to fixtures and floors in low pressure, and then wash the soils loose with a power rinse of always-fresh, clean water. The indoor pressure washer flushes soils out of grout lines and tight places that mops cannot reach. Then a user may vacuum the floor dry—completely removing soils, moisture, and biopollution from all surfaces, grout lines, and crevices, leaving the floor dry and soil free.
With regard to the pump, if desired, the pump may have the following specifications: 0.75-1.2 GPM, 150-500 PSI; 1.0-3.5 amps; and 120 VAC. Also, the spray line may be 25-50 feet in length, and may have an ID of ¼-⅜ inch. If desired, the pump system may have the following specifications: Spray Line: 32 feet (9.75 m); Quick-Connect Spray Gun; Electrical Cord: 25 ft. (7.6 m); Pressure: 150 psi (10.3 bars); Low Pressure Flow Rate: 1.20 GPM (4.5 l/min); and High Pressure Flow Rate: 0.30 GPM (1.1 l/min).

Modular multi-functional cleaning and floor care system embodiments, in accordance with the present invention, may be made using any suitable material(s) and manufacturing technique(s). For example, if desired, the reservoir assembly may be made of polypropylene using injection molding; and the wet/dry vacuum tank may be made of plastic using rotational molding.
In use, the modular multi-functional cleaning and floor care system provides many benefits and advantages, several of which have been mentioned in this patent document. If desired, the system may be used by one user/worker. Alternatively, the system may be used by multiple users/workers—simultaneously. For example, the wet/dry vacuum assembly and the reservoir assembly may be separated from each other; and one worker may apply cleaning solution with the reservoir assembly, while another worker brushes the work surface on which the solution has been applied, and vacuums up the soil-containing solution.
While the present invention has been illustrated by a description of embodiments, and while the illustrative embodiments have been described in considerable detail, it is not the intention of the inventors to restrict or in any way limit the scope of the following claims to such detail. For example, in another embodiment, a wipes container is provided in which a first roll of dry wipes already is packaged in the container (e.g., during manufacture and assembly by a manufacturer). Additional advantages and modifications readily will appear to those skilled in the art upon a reading of this patent document. The invention, in its broader aspects, is therefore not limited to the specific details, representative apparatus and methods, and illustrative examples shown and described in this patent document. Accordingly, departures may be made from such details without departing from the spirit or scope of the inventors' general inventive concept.
