The cylindrical side wall 125 of the stepper 123 directs the cleaning fluid 202 to flow within the central hollow area 127 of the foot platform 126 and prevents splashing the cleaning fluid 202 other than the footwear sole 200. After cleaning the sole of the first footwear, the user can then place the second footwear on the device 100 and clean the sole of the second footwear in the same manner.

(51) In an exemplary embodiment as shown in FIGS. 1, 10 and 12A, the one or more legs 128 of the cylindrical side wall 125 rest on the panel 104 when the foot trigger 124 is fully pressed, thereby preventing excess pressure on the spray trigger 122.

(52) In another exemplary embodiment, the foot trigger 124 or cylindrical wall 125 can be made of flexible material, thereby allowing the foot trigger to be pressed to bend the foot trigger 124 to a desired angle to press the spray trigger to a desire position as per the flow intensity of the cleaning fluid 202 desired by applying the subsequent amount of foot pressure by the user on the foot trigger 124. Further, any such modification to the design for controlling the pressure on the spray trigger 122 can be achieved without departing from the scope and spirit of the present invention.

(53) In an exemplary embodiment, the annular surface 129 is sloped towards the spray head 122 such that the discharged cleaning fluid 202 and debris from the footwear sole 200 flow freely within the cylindrical wall 125 of the stepper 123 and beneath the elevated base 102 as shown in FIGS. 1, 2, and 11, so as to facilitate a user to place the shoe in a desired position while cleaning the footwear sole 200 by the discharged cleaning fluid 202 and allowing the discharged cleaning fluid 202 and debris from the footwear sole 200 to flow freely within the central hollow area 127 of the cylindrical side wall 125 of the stepper 123 and beneath the elevated base 102 through the multiple apertures 108 in the elevated base 102, thereby preventing splashing of the cleaning fluid 202 and the debris (FIG. 12A). The user can press down with different sections of the footwear sole 200 to clean the respective section of the footwear sole 200 while pressing the foot trigger 124 by pressing the foot platform 126 from any suitable direction (FIG. 12B). And as discussed above, intensity of the cleaning fluid 202 can be adjusted to accommodate different cleaning needs and footwear sole types.

(54) FIGS. 13A and 13B illustrate perspective views of the device 100 showing that the sprayer 114 of the device 100 can be used to clean the device itself. This self-cleaning feature is possible because the spray head 122 detaches from the bracket 112 on the base 102. FIG. 13A shows the foot trigger 124 being pivotally displaced away from the base 102, which also serves to move the device 100 to an open (non-operational) position. FIG. 13B shows the sprayer 114 detached from the base 102 and spraying the cleaning fluid 202 on to the stepper 123 and the base 102. In this manner, debris from the footwear sole 200 is removed from the base 102 and the stepper 123. The cleaning fluid 202 flows beneath the elevated base 102 during self-cleaning, as in cleaning the footwear sole 200. It is significant to note that when the sprayer 114 is detached from the base 102, the spray trigger 132 is depressed with the hands of the user for cleaning the device 100. Further the sprayer 114 can be used for other cleaning purposes such as watering plants and the like. The device 100 is portable by allowing the stepper 123, the base 102 and the sprayer 114 dissembled to be carried separately for easy and quick transportation to a golf court, construction site or the like as per the user's requirement.

(55) FIG. 14 illustrates a flowchart diagram of an exemplary method 300 for hands-free cleaning of a footwear sole. The method 300 may include an initial Step 302 of positioning an elevated base on a ground surface. The method 300 may further comprise a Step 304 of detachably attaching a sprayer to the elevated base and holding the sprayer is in a desired position by the bracket and one or more stoppers on the base in a snap fit relationship, wherein the sprayer defined by an elongated hollow body for carrying a cleaning fluid, an inlet end for receiving the cleaning fluid, and a discharge end for discharging the cleaning fluid, the discharge end of the sprayer comprising a spray head, the body of the sprayer further comprising a pressure actuated and spring biased spray trigger for actuating discharge of the cleaning fluid. A Step 306 includes supplying the cleaning fluid into the body of the sprayer from a source.

(56) In some embodiments, a Step 308 comprises pivotally positioning a stepper over the spray head by a footwear sole of a user, wherein the stepper is joined to the base at a hinge, further the stepper comprising a foot platform, a foot trigger, a cylindrical side wall and one or more legs extended from the side wall, the foot platform comprises an annular surface and a central hollow area. A Step 310 includes engaging a slot between two consecutive legs of the stepper with the elongated body of the sprayer, thereby allowing the foot trigger to remain in a desired position over the spray trigger, a Step 312 may include placing the footwear sole of the user on the annular surface of the foot platform of the stepper, whereby the central hollow area of the foot platform is configured to expose the spray head towards the footwear sole of the user. A Step 314 may include pressing the foot trigger by the footwear sole to press the spray trigger. A Step 316 comprises controlling the intensity of the discharged cleaning fluid, wherein the intensity of the discharged cleaning fluid is directly proportional to the amount of foot pressure applied on the spray trigger through the foot trigger, wherein the one or more legs of the cylindrical side wall rest on the elevated base when the foot trigger is fully pressed, thereby preventing excess pressure on the spray trigger. A Step 318 may include discharging the cleaning fluid from the spray head through the central hollow area of the foot platform to provide a hands-free cleaning of the sole of the footwear. A final Step 320 comprises allowing the discharged cleaning fluid and debris that is dislodged from the footwear sole to flow freely within the cylindrical wall of the stepper and beneath the elevated base through the multiple apertures in the elevated base, thereby prevent splashing of the cleaning fluid and the debris.
