ABSTRACT:

FIELD OF THE INVENTION
This application relates to the field of cleaning implements, and more particularly to the field of brooms.
DESCRIPTION OF RELATED ART
A conventional push broom is a device that is commonly used to clean floors. Such a push broom is shown in FIG.
1
. The components of push broom may include a broom handle
1
and a broom head
3
with attached bristles
2
. The cleaning action of the broom is provided by the user exerting a downward force on the handle
1
while pushing forward, which causes the bristles
2
attached to the broom head
3
to push loose debris on a surface, such as a floor, to another location. The user then lifts the broom head
3
slightly and pulls backward, such that the broom head
3
is repositioned to repeat the cleaning action.
With a conventional push broom it usually takes several passes of the broom head to completely clean an area. For example, when attempting to sweep grass clippings off a concrete or asphalt surface, often the clippings partially adhere to the surface, which causes a rolling effect under the bristles as the bristles attempt to push the clippings away. The result is many of the clippings remain in the area just swept, which in turn requires the user to repeat the sweeping action in the same area several times in order to remove all of the debris. The need for such repetition can also be observed when sweeping sand, dirt or small rocks on a similar surface. Nevertheless, the conventional push broom is a device that is most commonly used to clean floors or other similar surfaces.
Debris can be removed from a floor surface by water pressure exerted by a hose nozzle attached to a common garden hose. An example of such a hose nozzle is illustrated in FIG.
11
. The hose nozzle is a hand held device and, when activated while pointed at the floor, requires several horizontal and vertical motions in order to remove debris. With this method a significant amount of time and effort required to clean a large area. This method of cleaning can be ineffective if the debris content is high, partially stuck to the floor, relatively large or relatively heavy. In addition, the remaining water on the floor surface may cause puddling and require excessively long drying times.
Wheel-mounted spray systems are also known. These devices are generally called water brooms. An example of such a broom is shown in FIG.
12
. This type of device uses the force of water to lift and push debris. Given the spray jets' close proximity to the floor, these devices can be effective when attempting to remove loose and relatively small debris from a floor. However, if the debris is larger or heavier, several cleaning passes may be required. When using this system, an area can be swept faster than the hose nozzle method mentioned above. However, 1) with normal household water pressures of 40 to 60 PSI these devices may be marginally effective in removing larger stones, gravel and other similar debris, 2) with normal water pressure, these devices may have limited abrasive cleaning characteristics, and mechanical pushing ability, 3) a pressure boosting device may be required in order to achieve the desired cleaning effectiveness, 4) with higher water pressures, the high misting effect can damage surfaces such as drywall in garages, 5) the cleaning action is provided only by the force of water which may be inappropriate in certain areas of a floor, 6) the water and debris on the floor can only be moved and directed with the spray of additional water, 7) as water pools in front of the device the pushing effectiveness of the water spray diminishes, thus allowing water and debris to flow around and behind the device, 8) higher amounts of water are required in order to clean a given surface, 9) the floor surface can remain very wet after use, 10) significant puddling can occur after use, 11) the floor drying time may be excessive due to the high amount of water remaining on the floor, 12) the remaining water on the floor may need to be removed by a push broom or squeegee, and 13) the corrosive effects of water, salt and grime, will cause the wheels or castors to deteriorate and become inoperable over time.
The water broom and similar devices are documented in several United States patents, the disclosures of which are incorporated by reference herein, including U.S. Pat. Nos. 3,931,931, 4,022,382, 4,083,495, 4,095,746, 4,930,706, Des. 243,610, Des. 244,532, Des. 250,826, and Des. 277,499.
FIG. 13
shows an example of a device which combines brush and water technology. Pictured is a model 8540 cleaning device manufactured by Mr. LongArm, Inc. This device features a water cut-off turn valve
100
, with an exploded view
101
, and a brush head
104
, with an exploded view of the bottom
105
. This device also features an extendable broom handle
102
which is adjusted at
103
.
FIG. 15
shows a flow chart that lists the procedures for the brush device's use. Referring to
FIGS. 13 and 15
, and starting at step
130
, the user connects a garden hose to the water service and the brush device at
100
. The user checks that the water cut-off valve
101
is turned off, at step
131
. The user turns on the water service, at step
132
. While holding the broom handle
102
, the user positions the brush head
104
near the surface to be cleaned, at step
133
. At step
134
, the user turns the valve control
101
such that water passes through the valve
101
, the broom handle
102
and emerges from a hole
107
at the bottom of the brush head
105
. The user pushes the brush head
104
onto the surface to be cleaned, at step
135
. At step
136
, the user induces a back and forth action on the broom handle
102
such that the brush head
104
scrubs the desired surface. At step
137
, if additional cleaning is required, step
136
is repeated. If not, at step
138
, the user removes the brush head
104
from the surface, turns off the water cut-off valve
101
and stops. This device may be useful when cleaning surfaces such as walls, vinyl siding, cars, tires and other sloping or substantially vertical surfaces. The general release of water near the brush bristles and the scrubbing action is very effective for these surfaces. The issue of where the water goes is generally not a problem because the water falls and drips off the item being cleaned. However, this type of device may not be appropriate for cleaning floors or other similar horizontal surfaces. When used on a floor, the water emerges on the floor in an arbitrary manner. There is no directional control of the water from the brush head, which makes this device difficult to use in floor sweeping applications. In addition, the lack of easy control of the water flow at the cut-off valve may add another layer of difficulty and complexity to the operation on such surfaces. This type of device may simply not be practical for sweeping floors. Other examples of this art can be found in patents including Russell, British Patent 485,219, accepted May 17, 1938, Schwartz, U.S. Pat. No. 2,908,445, issued Oct. 13, 1959, Brown, British Patent 1,243,775, published Aug. 25, 1971, and Hammond, U.S. Pat. No. 4,575,270, issued Mar. 11, 1986. Cohen, British Patent 677,741, published Aug. 20, 1952, Soultanian, U.S. Pat. No. 3,806,261, issued Apr. 23, 1974, and Diaz, U.S. Design Patent Des. 404,923, issued Feb. 2, 1999 teach a water brush for cleaning floors.
Accordingly, a need exists for a device that overcomes the drawbacks of the devices described above and that is practical for sweeping floors and other horizontal surfaces.
SUMMARY OF THE INVENTION
The invention herein provides a unique, highly effective, practical and easy to use and assemble floor sweeping system.
Provided herein is a device for sweeping a substantially horizontal surface, which includes a broom having a handle and a head, a valve disposed on the device, and a spray bar disposed on the head for directionally spraying a liquid that is supplied to the valve, wherein the valve regulates the pressure of liquid sprayed by the spray bar. The liquid ma
