Description




BACKGROUND OF THE INVENTION




The present invention relates to cleaning equipment, and more particularly to cleaning equipment for cleaning surfaces.




Cleaning equipment is used extensively for cleaning the surfaces of sinks, urinals, toilets, windows, shower stalls, tiles, stone, brick, locker rooms, swimming pool areas and other surfaces.




Heretofore, cleaning surfaces had included the steps of spraying a cleaning fluid onto the surfaces, blow drying the surfaces and/or vacuuming the fluid off of the surfaces. The cleaning equipment used in cleaning the surfaces typically included a single blower motor used for both vacuuming and blowing. The blower motor typically included an air intake and an air outlet. The cleaning equipment also typically included a tube configured to be connected to the air outlet of the vacuum motor for blow drying the surfaces and for pushing the fluids on the surfaces in a certain direction for later suctioning. The tube also can be connected to the air intake of the vacuum motor for suctioning the fluids off of the surfaces. However, the use of one blower and one tube for both blowing the surfaces and suctioning the fluids off of the surfaces can allow the surface to remain contaminated. Once the fluids are suctioned off of the surfaces, germs and bacteria in the fluid adhere to the side walls of the tube or the blower. Therefore, once the tube and the vacuum motor is used to vacuum off of the surfaces during a previous use, the germs and bacteria could be blown back onto the surfaces during drying. Consequently, the surfaces will typically always have some germs and bacteria as this cycle continues.




Accordingly, an apparatus solving the aforementioned disadvantages and having the aforementioned advantages is desired.




SUMMARY OF THE INVENTION




The present invention comprises a method for cleaning surfaces and a device used therein comprising a tank and motor housing with a fluid pump assembly, a blower assembly and a vacuum assembly located within the tank and motor housing. The tank and motor housing is adapted to contain a cleaning fluid. The fluid pump assembly includes a pump motor configured to pump the fluid in the tank and motor housing through a sprayer hose and onto the surfaces. The blower assembly includes a blower motor configured to blow air through a blower hose and onto the surfaces for directing movement of the fluid on the surfaces and drying the surfaces. The vacuum assembly includes a recovery tank and a vacuum motor configured to vacuum the fluid with the vacuum motor off of the surfaces, through a vacuum hose and into the recovery tank, thereby cleaning the surfaces.




The principal objects of the present invention include providing a cleaning device assembly for cleaning surfaces. The cleaning device assembly provides a safe and clean device for cleaning sinks, urinals, toilets, windows, shower stalls, tiles, stone, brick, locker rooms, swimming pool areas and other surfaces. The cleaning device assembly includes separate vacuum and blower assemblies, thereby preventing contamination of the two systems. The cleaning device assembly further includes separate vacuum and blower hoses for preventing contamination of the blower hose. The cleaning device assembly is efficient in use, economical to manufacture, capable of a long operable life, and particularly adapted for the proposed use.




These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.

) pivotally connects a rear lower edge of the upper housing


38


of the tank and motor housing


36


to a rear upper edge of the lower housing


40


of the cleaning device


12


. The cleaning device


12


is in a closed position (

FIG. 1

) when the upper housing


38


is located directly above the cavity


44


of the lower housing


40


. A pair of snap lock latches


50


attached to a lower portion of the upper housing


38


engages a pair of downwardly facing hooks


52


(

FIG. 6

) on the lower housing


40


for maintaining the cleaning device

and the front surface


54


of the upper housing


38


is lifted to move the cleaning device


12


into an open position (

FIG. 3

) to expose the lower housing


40


. The lower housing


40


also includes a pair of front wheels


56


configured to pivot about a vertical axis and a pair of rear wheels


58


for easily moving the tank and motor housing


36


. The handle


42


has a substantially U-shaped cross section, with ends of the U-shaped cross section connected to the rear face of the upper housing


38


. The interior of the U-shaped cross-section of the handle


42


slopes downwardly towards the rear face of the upper housing


38


to define an open-topped compartment


60


. The handle


42


also includes an inverted U-shaped grip bar


62


extending from the top of the handle


42


. The grip bar


62


is grasped by a user and pushed to move the tank and motor housing


36


with the front wheels


56


and the rear wheels


58


.




The upper housing


38


(

FIGS. 4 and 5

) of the tank and motor housing


36


includes a first recessed opening


64


, a second recessed opening


66


, a vacuum fitting


68


and a drain hose fitting


70


opening into the interior of the upper housing


38


. The first recessed opening


64


and the second recessed opening


66


are aligned front to back in the top surface


72


of the upper housing


38


. Screw-on lids


74


located in the first recessed opening


64


and the second recessed opening


66


enclose the interior of the upper housing


38


from the surrounding environment. The vacuum fitting


68


comprises a cylindrical tube and extends from the front surface


54


of the upper housing


38


. The vacuum fitting


68


is configured to be frictionally engaged with the vacuum hose


14


for connecting the vacuum hose


14


to the cleaning device


12


. The drain hose fitting


70


is located in the bottom corner of the rear face of the upper housing (see

FIGS. 2

,


4


and


5


). The drain hose fitting


70


is connected to a drain hose


76


. As explained in more detail below, the drain hose


76


is used to evacuate fluid that is recovered from the surfaces from the interior of the upper housing


38


. The upper housing


38


further includes a pair of vacuum hose hooks


78


extending outwardly and upwardly from an upper portion of the front surface


54


of the upper housing


38


on both sides of the vacuum tube fitting


68


. The vacuum hose hooks


78


receive the vacuum hose


14


for easily transporting the vacuum hose


14


with the cleaning device


12


. Likewise, a sprayer hose hook


81


extends outwardly and upwardly from a central portion of the front surface


54


of the upper housing


38


below the vacuum tube fitting


68


for receiving the sprayer hose


16


for transportation with the cleaning device


12


.




The upper housing


38


further includes a rinser fluid tank


80


, a cleaner fluid tube


81


and an inverted L-shaped vacuum pipe


82


located in the interior of the upper housing (FIG.


5


). The rinser fluid tank


80


is connected to the bottom face of the top surface


72


of the upper housing


38


and includes an annular top opening


82


that surrounds the first recessed opening


64


. The rinser fluid tank


80


also includes a bottom opening


84


connected to a first pipe


86


and a second pipe


88


coupled with a pump motor


90


(FIGS.


3


and


7


). As explained in more detail below, a rinser fluid is injected into the rinser fluid tank


80


through the first recessed opening


64


and thereafter pumped through the second pipe


88


to apply the rinser fluid to the surfaces. The rinser fluid tank


80


can have a rigid wall or a flexible wall. When a flexible wall is used for the rinser fluid tank


80


, the internal volume of the rinser fluid tank


80


can shrink as the fluid is removed from the rinser fluid tank


80


. A screen


96


is located over the bottom opening


84


in the rinser fluid tank


80


for stopping solid particles from entering the first pipe


86


and the second pipe


88


. The cleaner fluid tube


81


extends from the open topped compartment


60


of the handle


42


, through the handle


42


(FIG.


8


), through a rear wall


92


of the upper housing


38


, through a wall of the rinser fluid tank


80


and through the bottom opening


84


of the rinser fluid tank


80


. As explained in more detail below, cleaner fluid is pumped through the cleaner fluid tube


81


to the lower housing


40


to be selectively mixed with the rinser fluid for cleaning the surfaces. The rinser fluid tank


80


is fluidly separated from the cleaner fluid tube


81


and the remaining interior of the upper housing


38


. Therefore, the rinser fluid in the rinser fluid tank


80


cannot escape to the remainder of the interior of the upper housing


38


. Furthermore, the rinser fluid tank


80


does not contact any of the side walls of the upper housing


38


.




A recovery fluid tank


94


is defined by the interior of the upper housing


38


except for the area occupied by the rinser fluid tank


80


and the cleaner fluid tube


81


. The inverted L-shaped vacuum pipe


82


extends upward from the bottom surface of the interior of the upper housing


38


in a location below the second recessed opening


66


. A bottom end


96


of the vacuum pipe


82


is connected through an opening in the bottom surface of the upper housing


38


to a vacuum motor


98


. A top end


100


of the vacuum pipe


82


opens into the recovery fluid tank


94


. As explained in more detail below, the vacuum motor


98


, when activated, will create a suction force through the vacuum fitting


68


in the front surface


54


of the upper housing


38


to suck the fluids on the surfaces into the recovery fluid tank


94


. A shut-off float


102


is connected to the top end


100


of the vacuum pipe


82


. The shut-off float


102


will turn off the vacuum motor


98


when it contacts fluid in the recovery fluid tank


94


so that the recovery fluid will not be sucked into the vacuum motor


98


. If a flexible walled rinser fluid tank


80


is used, the volume of the recovery fluid tank


94


will enlarge as the fluid is removed from the rinser fluid tank


80


.




The lower housing


40


(

FIGS. 3

,


6


and


7


) of the tank and motor housing


36


houses the pump motor


90


, a pump hose


120


and portions of the cleaner fluid tube


81


, first pipe


86


and the second pipe


88


within the cavity


44


. The pump motor


90


includes a motor housing


106


for housing the motor of the pump motor


90


and a twin piston pump


108


. The motor in the motor housing


106


drives the twin pistons in the twin piston pump


108


. The motor housing


106


is suspended above the floor of the bottom housing


40


by a plurality of cylindrical mounts


114


(only one is shown in FIG.


6


). Likewise, a cylindrical mount


116


connects the twin piston pump


108


to a side wall of the lower housing


40


.




The illustrated twin piston pump


108


(see

FIG. 6

) includes a top opening


110


and a bottom opening


112


. A suction force is created through the bottom opening


112


and push force is created through the top opening


110


of the twin piston pump


108


. As seen in

FIGS. 2 and 7

, the top opening


110


of the twin piston pump


108


is fluidly connected to the first pipe


86


through a fitting


118


. Furthermore, the bottom opening


112


of the twin piston pump


108


is fluidly connected to the second pipe


88


. The first pipe


86


preferably has a smaller diameter than the second pipe


88


. Therefore, the pump motor


90


will pump a fluid through the first pipe


86


to the rinser fluid tank


80


and the second pipe


88


will suck fluid from the rinser fluid tank


80


back to the pump motor


90


. Since the first pipe


86


has a smaller diameter than the second pipe


88


, a net amount of fluid will flow from the rinser fluid tank


80


to the pump motor


90


.




Fitting


118


is attached to the twin piston pump


108


and is also connected to the pump hose


120


. The net amount of fluid from the rinser fluid tank


80


described directly above is diverted through the fitting


118


and into the pump hose


120


. The pump hose


120


extends from the fitting


118


connected to the twin piston pump


108


to an injector


122


connected to an interior surface of the front wall of the lower housing


40


. A male fitting


124


located in an opening


126


in the front wall of the lower housing


40


is also connected to the injector


122


. Therefore, fluid in the rinser fluid tank


80


is pushed by the pump motor


90


through the second pipe


88


, into the twin piston pump


108


, into the fitting


118


, through the pump hose


120


, into the injector


122


and into the male fitting


124


in the front wall of the lower housing


40


. The male fitting


124


extends from the exterior of the front wall of the lower housing and is configured to be connected to the sprayer hose


18


for pumping the fluid from the rinser fluid tank


80


through the sprayer hose


18


.




Cleaner fluid tube


81


extends through the cavity


44


of the lower housing


40


and is fluidly connected to the injector


122


. The injector


122


siphons the cleaner fluid in the cleaner fluid tube


81


and joins the cleaner fluid with the fluid flowing through the pump hose


120


. Preferably, the cleaner fluid container


32


is placed into the open-topped compartment


60


of the handle


42


and a first end


126


(

FIG. 8

) of the cleaning fluid tube


81


is inserted into the cleaner fluid container


32


. When the pump motor


90


is started, fluid will flow through the pump hose


120


, thereby creating a suction force in the cleaner fluid tube


81


because of the siphon characteristics of the injector


122


. The cleaner fluid can therefore be pumped through the sprayer hose


18


with the fluid from the rinser fluid tank


80


. As seen in

FIGS. 1

,


3


and


7


, the cleaner fluid tube


81


is connected to a toggle valve


128


adjacent the front wall of the lower housing


40


. The toggle valve


128


includes a handle


130


extending through an aperture


132


in the front wall of the lower housing


40


. The handle


130


can be lifted away from the exterior of the front wall of the lower housing


40


to an off position wherein the flow of cleaner fluid through the toggle valve


128


and the cleaner fluid tube


81


is stopped. The handle


130


can also be pushed towards the exterior of the front wall of the lower housing


40


to an on position wherein the cleaner fluid is allowed to flow through the toggle valve


128


and the cleaner fluid tube


81


. Therefore, when the handle


130


is moved to the off position, only the fluid from the rinser fluid tank


80


will flow through the injector


122


and the male fitting


124


.




In the illustrated example, the lower housing


40


(

FIGS. 2

,


6


and


7


) of the tank and motor housing


38


also includes a blower motor


104


within the cavity


44


. An L-shaped bracket


134


attaches the blower motor


104


to the floor of the cavity


44


of the lower housing


40


. The L-shaped bracket


134


includes a screen


136


for preventing solid particles from entering an air intake


138


of the blower motor


104


. A flexible pipe


140


extends from the blower motor


104


to an opening


142


in the rear wall of the lower housing


40


. As seen in

FIGS. 2 and 7

, the flexible pipe


140


is connected to a cylindrical fitting


144


extending through the opening


142


in the rear wall of the lower housing


40


. The blower motor


104


sucks air in through the air intake


138


and blows the air through the flexible pipe


140


and out of the lower housing


40


through the cylindrical fitting


144


. The cylindrical fitting


144


preferably includes a barbed outer surface outside of the lower housing


40


. The cylindrical fitting


144


is configured to be engaged with the blower hose


16


for blowing air through the blower hose


16


.




Lower housing


40


has an opening in the floor of the cavity


44


connected to an outlet pipe


146


for the vacuum motor


98


(

FIGS. 3

,


5


and


6


). The outlet pipe


146


allows the air sucked by the vacuum motor


98


to exit through the floor of the cavity


44


. The floor of the cavity


44


also includes an annular opening


148


for accepting a bottom end


150


of the vacuum motor


98


for accommodating the vacuum motor


98


in the cavity


44


when the cleaning device


12


is in the closed position. Handle


42


(

FIGS. 1-3

and


8


) includes the open-topped compartment


60


, the cleaner fluid tube


81


and the grip bar


62


as described above. The handle


42


also includes a power cord


152


, a drain hose bracket


154


, a pair of wand clips


156


on each side of the handle


42


, a brush clip


158


, an operation dash


160


and an hour meter


161


. The power cord


152


powers each of the motors in the cleaning device


12


. The power cord


152


preferably includes a ground fault circuit interrupter


162


for protecting users of the cleaning device assembly


10


against electrical shock. The drain hose bracket


154


is attached to a side of the handle


42


and has a pair of prongs


164


extending away from the handle


42


for engaging the drain hose


76


and holding the drain hose


76


in an upright position. The wand clips


156


are U-shaped clips attached to each side of the handle


42


. One pair of the wand clips


156


on one side of the handle is configured to hold the first piece


22




a


of the two piece double bend wand and another pair of wand clips


156


on the other side of the handle


42


is configured to hold the second piece


22




b


of the two piece double bend wand. The brush clip


158


is a U-shaped clip located in the compartment


60


of the handle


42


. The brush clip


158


is configured to retain the floor brush


20


on the cleaning device


12


. Therefore, the two piece double bend wand and the floor brush are retained by the handle


42


when not in use for easy transportation with the cleaning device


12


. The operation dash


160


includes a first switch


166


having a position for powering the blower motor


104


, a position for powering the vacuum motor


98


and an off position. The first switch


166


can therefore at a single time only select either the position for powering the blower motor


104


or the position for powering the vacuum motor


98


. In the preferred embodiment of the cleaning assembly


10


, the first switch


166


can only select one of the motors because of the power requirements of the preferred motors and the limitation currently available from a typical outlet. The operation dash


160


also includes a second switch


168


having a position for powering the pump motor


90


and an off position. The hour meter


161


is located below the operation dash


160


and indicates the amount of time that the pump motor


90


has been in use, and therefore allows a user of the cleaning device assembly


10


to schedule planned maintenance and monitor productivity. The blower hose nozzle


24


, the spray gun


26


, the squeegee floor tool attachment


28


, the gulper tool


30


, the cleaner fluid container


32


, the rinser fluid container


34


; and the tank fill hose


35


can be placed within the compartment


60


of the handle


42


when the cleaning assembly


10


is not in use for easy transportation of the accessories of the cleaning assembly


10


. Furthermore, the sprayer hose


18


can be wrapped around the grip bar


62


of the handle


42


when not in use for easy transportation with the cleaning device


12


.




The assembly


10


is used to clean surfaces by first placing the cleaner fluid container


32


in the compartment


60


of the handle


42


. The cleaner fluid is preferably Formula


710


Multi-Surface Acid Cleaner sold by Tennant Inc. of Holland, Mich. The cleaner fluid tube


81


is then inserted into the cleaner fluid container


32


. The cleaning device assembly


10


preferably includes metering tips that can be threaded onto the first end


126


of the cleaner fluid tube


81


in order to selectively meter the amount of cleaner fluid entering the cleaner fluid tube


81


. Preferably, the metering tips have different colors representing different flow rates through the cleaner fluid tube


81


. The metering tips preferably meter about 2 ounces of the cleaner fluid per gallon of rinser fluid for light cleaning, 4 ounces of the cleaner fluid per gallon of rinser fluid for medium cleaning and 6 ounces of the cleaner fluid per gallon of rinser fluid for heavy cleaning.




The rinser fluid tank


80


is thereafter filled with the rinser fluid by removing the lid


74


from the first recessed opening


64


and adding a selected amount of the rinser fluid from the rinser fluid container


34


into the rinser fluid tank


80


. The rinser fluid is preferably added to the rinser fluid tank


80


according to dilution instructions on the rinser fluid container


34


. The rinser fluid is preferably Formula


720


Multi-Surface Rinse sold by Tennant Inc. of Holland, Mich. The tank fill hose


35


is then connected to a source of water and the rinse fluid tank


80


is filled with water. The tank fill hose


35


preferably includes a fitting


170


that allows the tank fill hose


35


to be connected to most standard faucets. After the rinser fluid tank


80


is full of diluted rinser fluid, the lid


74


is replaced in the first recessed opening


64


. The cleaning device assembly


10


is now ready for operation.




If the area having the surfaces to be cleaned is not equipped with a floor drain, the vacuum hose


14


is connected at one end to the vacuum fitting


68


and at the other end to the gulper tool


30


. The gulper tool


30


includes a rectangular housing


172


that can be placed on the floor surface of the area. A plurality of openings


174


in the housing


172


allow fluid to enter the housing


172


when the gulper tool


30


is placed on the floor surface. The gulper tool


30


is preferably placed at a position where fluids in the room may puddle during operation of the cleaning assembly


10


. When the vacuum motor


98


is activated, the gulper tool


30


will allow fluid on the floor to be sucked through the gulper tool


30


, through the vacuum hose


14


, through the vacuum fitting


68


and into the recovery fluid tank


94


. Furthermore, once the vacuum motor


98


is activated, the gulper tool


30


will create a vacuum under the housing


172


of the gulper tool


30


, thereby keeping the gulper tool


30


in position on the floor surface.




The sprayer tube


18


and the spray gun


26


are then connected to the cleaning device


12


before the surfaces are sprayed. The sprayer tube


18


(

FIG. 11

) preferably includes a female quick coupler


176


at one end of the sprayer tube


18


. The female quick coupler


176


is engaged with the male fitting


124


extending from the front wall of the lower housing


40


of the cleaning device


12


. The other end of the sprayer tube


18


includes a male quick coupler


178


. The spray gun


26


(

FIG. 13

) is connected to the sprayer tube


18


by engaging a female quick coupler


180


on the spray gun


26


with the male quick coupler


178


on the sprayer tube


18


. Therefore, the spray gun


26


is fluidly connected to the male fitting


124


extending from the front wall of the lower housing


40


of the cleaning device


12


. The spray gun


26


also preferably includes a sliding nozzle


182


on the barrel of the spray gun


26


that allows the spray gun


26


to alternatively spray fluid at a high pressure thought the spray gun


26


or a low pressure through the spray gun


26


. The sliding nozzle


182


preferably can be turned to customize the spray pattern of the fluid coming from the spray gun


26


between a fan pattern and a single beam.




Thereafter, the handle


130


extending from the front wall of the lower housing


40


of the tank and motor housing


36


is lifted away from the exterior of the front wall of the lower housing


40


to the on position. Consequently, as described above, the cleaner fluid coming from the cleaner fluid container


32


is allowed to flow through the toggle valve


128


and the cleaner fluid tube


81


to the male fitting


124


extending from the front wall of the lower housing


40


, and therefore the spray gun


26


.




The sliding nozzle


182


of the spray gun


26


is then moved to a low pressure spray position and the pump motor


90


is activated. Furthermore, if the area having the surfaces to be cleaned is not equipped with a floor drain, the vacuum motor


98


is activated for suctioning fluid off of the floor surface with the gulper tool


30


. The spray gun


26


is then triggered to spray the surfaces in the room with a combination of the cleaner fluid and the rinser fluid. As described above, the cleaner fluid coming from the cleaner fluid container


32


through the cleaner fluid tube


81


and the toggle valve


128


and the rinser fluid coming from the rinser fluid tank


80


, the second pipe


88


, the twin piston pump


108


and the pump hose


120


will mix in the injector


122


when the handle


130


is in the on position. Thereafter, starting at the furthest point in the area, the surfaces are sprayed with a combination of the cleaner fluid and the rinser fluid with the spray gun


26


. Vertical surfaces are preferably sprayed bottom to top working towards the cleaning device


12


. After the surfaces have been sprayed, the pump motor


90


is turned off and the cleaner fluid and rinser fluid is allowed to work on the surfaces for a predetermined period of time. Furthermore, if the gulper tool


30


is being used, the vacuum motor


98


is turned off. Preferably, the combination of the cleaner fluid and the rinser fluid is allowed to work on the surfaces for 5-10 minutes. During this time, the floor brush


20


is preferably used to scrub corners and heavily soiled areas.




Once the cleaner fluid and the rinser fluid have worked on the surfaces, the handle


130


extending from the front wall of the lower housing


40


of the tank and motor housing


36


is pushed towards the exterior of the front wall of the lower housing


40


to the off position. Consequently, as described above, the cleaner fluid coming from the cleaner fluid container


32


is not allowed to enter the sprayer tube


18


. Furthermore, when the handle


130


is moved to the off position, a fluid path will be provided between the second pipe


88


and the first pipe


86


so that the maximum pressure available to the spray gun


26


is regulated such that the spray gun


26


can be used again without a delay while the pressure is maintained within the sprayer tube


18


and cleaner fluid tube


81


.




The sliding nozzle


182


of the spray gun


26


is then moved to the high pressure spray position and the pump motor


90


is activated. Once again, the vacuum motor


98


is activated if the area being cleaned does not include a drain. The spray gun


26


is then activated to spray only the rinser fluid on the surfaces. The spray gun


26


is preferably orientated such that the surfaces are sprayed from top to bottom. The rinser fluid preferably washes the fluids on the surfaces off of the surfaces such that no streaks occur on the surfaces.




After all of the surfaces have been rinsed with the rinser fluid, the pump motor


90


and the vacuum motor


98


are deactivated. The blower hose


16


is then connected at one end to the barbed outer surface of the cylindrical fitting


144


extending from the lower housing


40


of the tank and motor housing


36


. The blower hose nozzle


24


(

FIG. 12

) is then attached to the other end of the blower hose


16


. The blower motor


104


is then activated and the surfaces are blow dried with the air coming from the blower motor


104


. Furthermore, the rinser fluid is preferably pushed to the floor surface with the air coming through the blower hose


24


and the blower hose nozzle


24


. Once all of the wall surfaces are dry, the blower motor


104


is turned off. The fluid on the floor surfaces is preferably vacuumed up with the squeegee floor tool attachment


28


(FIG.


14


). The squeegee floor tool attachment


28


is used by first connecting the first piece


22




a


and the second piece


22




b


of a two piece double bend wand together. One end of the two piece double bend wand is then connected to the squeegee floor tool attachment


28


and the other end of the double bend wand is connected to the vacuum hose


14


. The vacuum motor


98


is then activated to suction the fluid off of the floor surface and into the recovery fluid tank


94


with the squeegee floor tool attachment


28


. After all of the fluid is vacuumed up with the squeegee floor tool attachment


28


, the vacuum motor


98


is turned off.




In the preferred embodiment, the recovery fluid tank


94


can be drained through the drain hose fitting


70


and the drain hose


76


. As explained above, the drain hose fitting


70


is located in the bottom corner of the rear face of the upper housing


38


. Therefore, the drain hose fitting


70


connects the drain hose


76


to the recovery fluid tank


94


. The drain hose


76


includes a flexible portion


200


adjacent to the drain hose fitting


70


. The flexible portion


200


allows the drain hose


76


to be lowered for emptying the recovery fluid tank


94


and raised for engagement with the drain hose bracket


152


on the handle


42


. The drain hose


76


also includes a plug


202


, a strap


204


and a T-shaped knob


206


adjacent a second end of the drain hose


76


. The plug


202


is inserted into the second end of the drain hose


76


for closing the drain hose


76


. The T-shaped knob


206


is screwed into the plug


202


for keeping the plug


202


within the drain hose


76


, and the T-shaped knob


206


is screwed out of the plug


202


for allowing the plug to be removed from the drain hose


76


. The strap


204


keeps the plug


202


and the T-shaped knob


206


connected to the drain hose


76


. When the drain hose


76


is not in use, the T-shaped knob


206


of the drain hose


76


is inserted between the pair of prongs


164


of the drain hose bracket


152


on the handle


42


for maintaining the drain hose near the handle


42


. If the vessel for depositing the fluid in the recovery fluid tank


94


is located at a vertical position below the recovery fluid tank


94


, the plug


202


is removed from the drain hose


76


and the drain hose


76


is lowered into the vessel. The recovery fluid tank


94


then drains because the fluid will flow into the vessel because of gravity. If the vessel for depositing the fluid in the recovery fluid tank


94


is located at a vertical position above the recovery fluid tank


94


, the blower hose


16


is connected at one end to the vacuum fitting


68


and at the other end to the cylindrical fitting


144


in the rear of the lower housing


40


. The blower motor


104


is then activated to pressurize the fluid recovery tank


94


and push the fluid through the drain hose


76


.




Since the cleaning device assembly


10


includes a vacuum motor


98


separate from the blower motor


104


, only one vacuum motor is used for both vacuuming fluids off of the surfaces and for blow drying the surfaces. Therefore, germs and bacteria vacuumed off of the surfaces with the vacuum motor


98


will not later be blown onto other surfaces with the vacuum motor


98


. The blower motor


104


should therefore remain relatively free of germs and bacteria during consecutive uses of the cleaning device assembly. Furthermore, separate vacuum and blower hoses help to keep the germs and bacteria from returning to the surfaces. Preferably, the vacuum hose


14


and the blower hose


16


have a different size and/or color so the two hoses will not be inadvertently used for the wrong function. Moreover, the blower motor


104


and the vacuum motor


98


will not function simultaneously because the first switch


166


only allows one to work at a time, thereby further protecting the cleaning device assembly


10


from contamination. Furthermore, the vacuum hose


14


preferably has a 1.5 inch diameter and the vacuum motor


98


preferably comprises a three stage vacuum pump for optimal suction. Another advantage of the disclosed cleaning device assembly, the use of a flexible walled fluid rinser tank


80


allows the cleaning device assembly


10


to have a compact design because the fluid rinser tank


80


will shrink as the fluid is removed from therein, thereby allowing the recovery fluid tank


94


to have a small initial volume. Since the internal volume of the recovery fluid tank


94


will enlarge as needed, the rigid walls of the recovery fluid tank


94


can have a small size, thereby allowing the cleaning device assembly


10


to have a small design.




In the forgoing description, it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed herein. For example, the cleaning device assembly could include a carpet cleaning accessory adapted to be connected to both the vacuum hose


16


and the sprayer hose


18


such that a carpet could be simultaneously sprayed with a carpet cleaner and vacuumed. Furthermore, it is contemplated that the rinser fluid in the rinser fluid tank


90


could comprise water. Such modifications are to be considered as included in the following claims, unless these claims by their language expressly state otherwise.
