Description

[Technical Field]

[0001] The present invention relates to a cleaning device, and more particularly to a cleaning device that can accommodate low vertical clearance areas. [Background technology]

[0002] Floor cleaning appliances have been available for decades for cleaning hard surfaces. One of the most difficult tasks users have with these appliances is cleaning under furniture and appliances. For floor cleaning in particular, the appliance should be able to fit into spaces with low vertical clearance.

[0003] Accommodating such small vertical clearances can be particularly problematic in self-contained cleaning appliances. For example, the problem of accommodating low vertical clearance space can be exacerbated in cleaning appliances to which bottles can be attached. The volume of the bottles can adversely affect the vertical clearance that the cleaning appliance can accommodate. And while a solution could be to substantially reduce the volume of the bottles, such measures are rarely successful.

[0004] Although lower volume bottles may allow for lower vertical clearance heights, the lower volume necessarily means that the bottles will need to be replaced more frequently. Unfortunately, consumers may view such devices as less valuable or wasteful given the more frequent bottle replacements. Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, what is needed is a cleaning implement that can accommodate low vertical clearance while still providing the user with sufficient bottle volume. [Means for solving the problem]

[0006] The cleaning apparatus of the present disclosure can accommodate low vertical clearances in furniture and appliances. In one example, the cleaning apparatus includes a cleaning head and a support member, the support member including: a first portion having a length, a first end and an opposing second end, and a handle disposed at the first end of the first portion; a second portion having a first transition portion disposed at the second end of the first portion and a second transition portion spaced from the first transition portion; a first support and a second support joining the first transition portion and the second transition portion; and a liquid management system disposed at least partially between the first transition portion and the second transition portion, the cleaning head being movably attached to the second transition portion. The liquid management system may include a reservoir receiving portion capable of receiving at least one liquid reservoir, or may include at least one liquid reservoir integrally formed with the reservoir receiving portion. The support member presents a longitudinal angle of 6 degrees or less with respect to the horizontal plane, the cleaning device presents a vertical height of less than 110 mm, and the liquid reservoir has a volume of greater than about 475 ml, more preferably greater than 500 ml, or most preferably greater than about 550 ml.

[0008] The cleaning device of the present disclosure can accommodate low vertical clearance while providing a sufficient volume of cleaning solution to a user. The cleaning device of the present disclosure includes a support member having a first portion and a second portion. The first portion has a length, a first end, and an opposite second end. The first portion of the support member is the portion primarily utilized by a user to operate the cleaning device during use.

[0009] The first portion may include a handle disposed on a first end of the first portion. The handle may be integrally formed with the first portion or may be a separate piece of material attached to the first portion. The handle may be pivotally connected to the first portion. Alternatively, the handle may be rigidly attached thereto. The handle may be provided to allow for a more ergonomic experience. Specifically, providing a handle may allow for ergonomic operation of the cleaning device.

[0010] The second portion of the support member has a first transition portion disposed at the second end of the first portion and a second transition portion spaced apart from the first transition portion. The first support and the second support join the first transition portion and the second transition portion. The cleaning head is movably mounted to the second transition portion.

[0011] The cleaning head may be movably mounted relative to the second transition section such that the support member, including the first and second portions, can pivot longitudinally relative to the cleaning head. Additionally, the cleaning head may be movably mounted relative to the second transition section such that the support member, including the first and second portions, can pivot transversely relative to or generally parallel to the cleaning head. Movement of the support member relative to the cleaning head in both the longitudinal and transverse directions is disclosed in further detail below.

[0012] The cleaning head may have a generally upwardly facing top surface and an opposing bottom surface. The cleaning head may have a leading edge, an opposing trailing edge, and two side edges joining the leading edge and the opposing trailing edge. The cleaning head's major axis lies at a centerline along the cleaning head's long dimension (and extends generally parallel to the leading edge and / or the opposing trailing edges). The cleaning head's minor axis lies at a centerline of the head parallel to its side edges and extends from the leading edge to the trailing edge.

[0013] For purposes or orientation, during use of the cleaning device of the present disclosure, the support member may move generally longitudinally during forward movement of the cleaning head, i.e., movement in which the leading edge and longitudinal axis of the cleaning head are generally perpendicular to the direction of movement, whereas the support member moves generally transversely during side-to-side movement of the cleaning head, i.e., when the leading edge and longitudinal axis of the cleaning head are generally parallel to the direction of movement.

[0014] Additionally, the support member may have a first portion height. With the bottom surface of the cleaning head perfectly flat relative to a plane, the first portion height is the maximum vertical extent of the first portion of the support member away from the plane, while the support member is oriented longitudinally and rotated toward the rear edge of the cleaning head as far as possible toward (but not through) the plane. While held in this same configuration, the vertical height is the maximum vertical extent of the second portion of the support member away from the plane. Also, while held in this same configuration, the length of the support member is the projection in a plane of the distance from the end of the first portion distal from the cleaning head to the intersection of the minor axis and the rear edge of the cleaning head.

[0015] The cleaning device of the present disclosure further includes a liquid management system at least partially disposed between the first transition section and the second transition section. The liquid management system includes a reservoir receiving section. The reservoir receiving section can be in liquid communication with at least one liquid reservoir. The at least one liquid reservoir can be removably attached to the reservoir receiving section or can be non-removably attached to the reservoir receiving section.

[0016] It is worth noting that one possible solution to accommodate lower vertical clearance is to reduce the volume of the liquid reservoir utilized by the cleaning device. However, such a configuration may result in a frustrating user experience in terms of difficult operation. Therefore, the cleaning device of the present disclosure may accommodate a liquid reservoir capable of holding a liquid volume of greater than about 475 ml, more preferably greater than about 500 ml, or most preferably greater than about 550 ml, including all values ​​within these ranges and any ranges formed thereby. For example, the cleaning device of the present disclosure may accommodate a liquid reservoir having a liquid volume of about 475 ml to about 800 ml, more preferably about 500 ml to about 800 ml, or most preferably about 550 ml to about 800 ml, including all values ​​within these ranges and any ranges formed thereby. In one specific example, the bottle volume may be approximately 750 ml.

[0017] Whether or not the liquid reservoir is removably attached to the reservoir receiving portion, the liquid reservoir may be refillable. Alternatively, the liquid reservoir may not be refillable, but instead may be replaceable. As an example, a first liquid reservoir may be attached to the reservoir receiving portion, and the first liquid reservoir may be removed and replaced with a second liquid reservoir upon use of all, substantially all, of the contents in the liquid reservoir, or simply when it is desired to replace the first liquid reservoir with a second liquid reservoir.

[0018] The liquid reservoir is at least partially disposed between the first transition portion and the second transition portion. If the liquid reservoir is non-removable, the first transition portion, the second transition portion, the first support, and the second support may be integrally formed with the liquid reservoir. If the liquid reservoir is removable, the first support and the second support may include a detent that provides support for the liquid reservoir. For example, a guide detent can provide support so that the liquid reservoir has limited lateral mobility. The detent can be any suitable shape, such as a bump, a ridge, a latch, or the like, or a combination thereof.

[0019] It is worth noting that the detents can be of any suitable shape and length. However, to facilitate removal and replacement of the liquid reservoir, the detents can be about 60 percent or less of the length of the liquid reservoir, more preferably about 50 percent or less, or most preferably about 40 percent or less, including all values ​​within these ranges and any ranges formed thereby. For example, the detents can have a length of about 1 percent to about 60 percent of the length of the liquid reservoir, more preferably about 1 percent to about 50 percent, or most preferably about 1 percent to about 40 percent. In one specific example, the detents can have a length of about 42 percent of the length of the liquid reservoir.

[0020] When the liquid reservoir is removably attached to the reservoir receiving portion, the cleaning device may include a release portion. The release portion may include a push button mechanism or other releasable latch mechanism to enable removal of the liquid reservoir from the reservoir receiving portion, the first support, the second support, the first transition portion, and / or the second transition portion. Actuation of the release portion may be translated into lateral movement of the transfer member. The transfer member may engage a complementary portion of the liquid reservoir in a first position and disengage from such portion in a second position. Operation of the release portion may cause the transfer member to engage and / or disengage from the complementary portion of the liquid reservoir.

[0021] Additionally, the cleaning device of the present disclosure may include a single liquid reservoir or multiple reservoirs. Multiple reservoirs may contain the same fluid therein, thus providing a greater volume than a single reservoir. Alternatively, the reservoirs may contain different fluids. Different fluids may be dispensed sequentially, or a particular fluid may be dispensed as needed for a particular task. If the reservoirs contain different fluids, the fluids may be dispensed simultaneously to allow mixing at the point of use on the target surface. When multiple liquid reservoirs are utilized, the cumulative liquid volume may be similar to that described above with respect to liquid reservoir volume.

[0022] Referring again to the first and second supports, the cleaning device may initially be provided (as stock) without a liquid reservoir connected to its reservoir receptacle, particularly if the liquid reservoir is removable. One or more liquid reservoirs may be included in the package with the cleaning device.

[0023] When the liquid reservoir is not connected to the reservoir receiving portion, a gap may exist between the first support and the second support. The gap may be sized so that the liquid reservoir can be connected to and removed from the reservoir receiving portion. For example, when the liquid reservoir is connected to the reservoir receiving portion, a space may exist between the top surface of the liquid reservoir and the first transition portion, allowing a user to easily grasp the liquid reservoir. In one specific example, the space between the transition portion and the top surface of the liquid reservoir may be approximately 20.4 percent of the length of the gap. In yet another example, the difference between the width of the gap and the width of the liquid reservoir may be approximately 14 percent of the width of the gap.

[0024] Despite the accommodation of the large-volume liquid reservoir of the cleaning device of the present disclosure, the inventors surprisingly found that the support member has a large range of motion in the longitudinal direction, particularly when addressing low vertical clearances. For example, in the longitudinal direction, the support member can exhibit a longitudinal angle of about 6 degrees or less relative to the horizontal plane, or more preferably, 5.8 degrees or less from the horizontal plane, including all values ​​within these ranges and any ranges formed thereby. For example, the support member can exhibit a longitudinal angle of about 2 degrees to about 6 degrees, or more preferably, about 2 degrees to about 5.8 degrees, including all values ​​within these ranges and any ranges formed thereby. In one specific example, the angle of the support member relative to the horizontal plane can be about 5.6 degrees. As used herein, the longitudinal angle is defined as the arctangent of the ratio of the height of the first portion to the length of the support member.

[0025] It is worth noting that the angle exhibited by the support member is only a part of the considerations regarding vertical clearance. As mentioned, the second portion may include the liquid reservoir within the reservoir receptacle and the cleaning head. These components occupy vertical space that may not necessarily be considered in measuring the longitudinal angle. Therefore, the vertical height of the cleaning device when the support member is at its smallest longitudinal angle relative to the horizontal plane may also be important. With respect to the cleaning device of the present disclosure, the vertical height of the cleaning device may be less than about 110 mm, more preferably less than about 100 mm, or most preferably less than about 95 mm, including all values ​​within these ranges and any ranges formed thereby. For example, the vertical height of the cleaning device of the present disclosure may be between about 70 mm and about 110 mm, more preferably between about 70 mm and about 100 mm, or most preferably between about 70 mm and about 95 mm, including all values ​​within these ranges and any ranges formed thereby. In one specific example, the vertical height may be about 88 mm.

[0026] Yet another feature of a cleaning implement that can affect the vertical height of the cleaning implement is the height of the first section. For cleaning devices of the present disclosure, the height of the first section can be less than about 120 mm, more preferably less than about 110 mm, including all values ​​within these ranges and any ranges formed therewith. For example, cleaning devices of the present disclosure can have a first section height of about 95 mm to about 120 mm, more preferably about 95 mm to about 110 mm, including all values ​​within these ranges and any ranges formed therewith. In one specific example, the height of the first section can be about 104 mm.

[0027] Aside from reducing the volume of the liquid reservoir, another way to accommodate lower angles is to lengthen the support member of the cleaning implement. However, while a longer support member may allow for a lower angle, a longer support member may also increase the difficulty of user manipulation during use. It is believed that a support member having a length greater than about 1400 mm may make the cleaning device more difficult for the user to operate. Therefore, the length of the support member of the cleaning device of the present disclosure may be less than about 1400 mm, more preferably less than about 1200 mm, or most preferably less than about 1100 mm, including all values ​​within these ranges and any ranges formed thereby. For example, the length of the support member of the cleaning device of the present disclosure may be between about 1000 mm and about 1400 mm, more preferably between about 1000 mm and about 1200 mm, or most preferably between about 1000 mm and about 1100 mm, including all values ​​within these ranges and any ranges formed thereby. In one specific example, the cleaning device of the present disclosure may have a support member length of about 1060 mm.

[0028] It is worth noting that to create not only a lower vertical height but also a lower longitudinal angle, the liquid reservoir, along with the reservoir receiving portion, can be flattened to have a transverse profile that is significantly larger than the longitudinal profile. However, while such a structure potentially addresses low vertical clearance concerns when viewed from the perspective of angular motion in the longitudinal direction, it can unfortunately create clearance issues when viewed from the transverse direction. In this regard, the cleaning device and its support member of the present disclosure can exhibit a transverse angle with respect to the horizontal plane of about 30 degrees or less, more preferably about 20 degrees or less, or most preferably about 15 degrees or less, including all values ​​within these ranges and any ranges formed thereby. For example, the support member can exhibit a transverse angle with respect to the horizontal plane of about 5 degrees to about 30 degrees, more preferably about 5 degrees to about 20 degrees, or most preferably about 5 degrees to about 15 degrees, including all values ​​within these ranges and any ranges formed thereby. In one particular embodiment, the support members may assume a transverse angle from about 9 degrees relative to the horizontal plane.

[0029] Similar to the longitudinal angle, the transverse angle is defined as having the bottom surface of the cleaning head perfectly flat relative to a plane, the support member height being the maximum vertical extent of the support member away from the plane, and the support member oriented transversely and rotated toward one of the cleaning head's side edges as far as possible toward (but not through) the plane. Also, while maintaining this same configuration, the length of the transverse support member is the projection on the plane of the distance between the end of the first portion distal from the cleaning head and the intersection of the cleaning head's minor and major axes. As used herein, the transverse angle is defined as the arctangent of the ratio of the height of the first portion to the length of the transverse support member.

[0030] The angles in the longitudinal direction, transverse direction, vertical height of the cleaning apparatus, height of the first section, height of the support member, and length of the support member may be collected via any suitable linear measuring device, such as a Mitutoyo Coordinate Measuring Machine (CMM), Crystal-Plus Model #M574, or equivalent.

[0031] In addition to the reservoir receptacle, the liquid management system may further include a pump in liquid communication with the reservoir receptacle and the liquid reservoir. Note that if the liquid reservoir is removable, the pump is in liquid communication with the liquid reservoir only when the liquid reservoir is attached to the reservoir receptacle. Additionally, the pump is in liquid communication with one or more nozzles / outlets. The nozzles / outlets may be disposed in the cleaning head and / or any other suitable location.

[0032] The first portion, e.g., the handle, may include an actuator for operating the pump. For example, the actuator may be operably connected to the pump such that depression of the actuator energizes a motor that drives the pump, thereby forcing liquid from a liquid reservoir connected to the reservoir receiving portion through one or more outlets and / or nozzles. It is worth noting that the motor may be in electrical communication with a power source, e.g., one or more batteries, line current, or a combination thereof. The one or more batteries may be rechargeable. The battery and / or pump may be disposed within the cleaning head, the support member, or a combination thereof. For example, the battery may be disposed on the support member, while the motor and pump may be disposed on the cleaning head, or all three components may be disposed on the support member or head.

[0033] Alternatively, the pump may be manual and require an actuator to be activated, displaced, or otherwise moved, thereby activating the pump. Or, the pump may comprise an air pump that may be utilized to pressurize a liquid reservoir. An actuator in the first portion may open a valve to allow liquid to flow to one or more nozzles and / or outlets. A cleaning device having a replaceable reservoir and electric pump may be constructed in accordance with the teachings of commonly assigned U.S. Patent Nos. 5,888,006, 5,988,920, 6,142,750, 6,206,058, 6,321,941, 6,328,543, 6,386,392, 6,491,069, 6,579,023, 6,814,519, 6,842,936, 7,172,099, and / or 7,187,537.

[0034] In yet other forms, the cleaning device of the present disclosure may not include a motor and pump. In such configurations, the cleaning device may be capable of receiving a pressurized liquid reservoir. Furthermore, in such structures, an actuator readily accessible by an operator of the cleaning device may be in mechanical communication with the liquid reservoir such that depression (or other activation of the actuator) causes pressurized contents within the liquid reservoir to be provided to one or more outlets / nozzles. Such a liquid reservoir may include any suitable means of pressurization, for example, via hydrocarbon propellant, nitrogen gas, etc.

[0035] It is worth noting that the placement of the liquid reservoir can significantly affect the operability of the cleaning device, especially when filled with liquid. For example, the support member may have an overall length. Similarly, the first portion may have a first portion length, and the second portion may have a second portion length.

[0036] One possible way to address low vertical clearance is to move the liquid management system closer to the first section and / or place the liquid management system only in the first section. However, doing so may negatively impact the user's experience. For example, the closer the liquid reservoir is to the handle, the greater the weight of these components the user must bear, especially if a full liquid reservoir is present. Therefore, placing the liquid management system, i.e., the liquid reservoir, in the first section may negatively impact the user's experience with the cleaning device.

[0037] To accommodate this, the length of the first portion is at least about 30 percent of the total length of the support member, more preferably at least 40 percent of the total length of the support member, or most preferably at least 50 percent of the total length of the support member. For example, the length of the first portion is 30-70 percent of the total length of the support member, more preferably 40-60 percent of the total length of the support member, or most preferably 50-60 percent of the total length of the support member.

[0038] Additionally, the center of gravity of the interior space of the liquid reservoir may be important. For example, in the cleaning device of the present disclosure, the center of gravity of the interior space of the liquid reservoir may be disposed in a vertical plane that is within about 40 mm of the bisecting plane of the support member, more preferably within 30 mm of the bisecting plane, or most preferably within about 20 mm of the bisecting plane, including all values ​​within these ranges and any ranges formed thereby. For example, the center of gravity of the interior space of the liquid reservoir may be separated longitudinally from the bisecting plane by about 0 mm to about 40 mm, more preferably about 0 mm to about 30 mm, or most preferably about 0 mm to about 20 mm, including all values ​​within these ranges and any ranges formed thereby. For clarity, the bisecting plane is oriented vertically and bisects the width of the first transition portion and / or the second transition portion when the support member is oriented vertically.

[0039] If the center of gravity of the interior space of the liquid reservoir, especially when full, is disposed outside these ranges when operably connected to the reservoir receiving portion, the cleaning device will be more difficult to operate. For example, the weight of the liquid reservoir can affect the position of the support member, especially when rotating / swiveling the cleaning device. This effect of the liquid reservoir weight can adversely affect the user experience. Various data for various cleaning implements was measured with respect to some of the metrics discussed above. The data is provided in Table 1.

[0052] Example 1 is a cleaning device constructed in accordance with the present disclosure.

[0053] To facilitate a further understanding of the foregoing metrics and disclosure, reference is now made to the figures. Figures 1A-1C illustrate a cleaning device 10 in accordance with the present disclosure. As shown, the cleaning device 10 comprises a support member 100 comprising a first portion 20 and a second portion 30. As shown, a handle 50 may be included in the first portion 20 and disposed on a first end 21 of the first portion 20. The second portion 30 may be disposed on a second end 31 of the first portion 20. Additionally, the cleaning device 10 comprises a cleaning head 40 attached to the second portion 30.

[0054] The longitudinal angle 80 of the support member 100 is shown relative to a horizontal plane 180. As previously mentioned, the cleaning apparatus of the present disclosure can exhibit a small angle 80 to accommodate low vertical clearance. Additionally, in this position, the cleaning apparatus of the present disclosure also exhibits a small vertical height, again allowing the cleaning apparatus of the present disclosure to accommodate low vertical clearance.

[0055] 1C, there is shown the transverse angle 90 of the support member relative to a horizontal plane 180. As previously mentioned, the cleaning apparatus of the present disclosure may exhibit a small angle 90 to accommodate low vertical clearance.

[0056] The issue of vertical clearance was discussed above with respect to the geometry of the liquid management system and / or liquid reservoir. Additionally, it is worth noting that a trade-off may exist between longitudinal vertical height and transverse vertical height. That is, as the desired longitudinal angle 80 decreases and / or the desired vertical height decreases, a corresponding increase in transverse angle 90 may occur.

[0057] Referring now to FIG. 2, an enlarged view of the second portion 30 is shown. The second portion 30 may include a first transition portion 30A disposed at the second end of the first portion 20. As shown, the first transition portion 30A may widen in a generally transverse direction as the transition moves from the second end of the first portion 20 toward the cleaning head 40. The second transition portion 30B is disposed opposite the first transition portion 30A. Similar to the first transition portion 30A, the second transition portion 30B may widen outward in a generally transverse direction and narrow as the second transition portion 30B moves toward the cleaning head 40.

[0058] The cleaning head 40 may be movably connected to the second transition portion 30B. For example, the cleaning head 40 may be pivotally connected to the second transition portion 30B such that the support member (item 100 shown in FIGS. 1A-1C) can move longitudinally and transversely relative to the cleaning head 40.

[0059] 2 , as shown, the first support 230A and the second support 230B are disposed between the first transition portion 30A and the second transition portion 30B. As shown, the first support 230A and the second support 230B can be joined to the first transition portion 30A and the second transition portion 30B. For example, the first support 230A and the second support 230B can be integrally formed with the first transition portion 30A and / or the second transition portion 30B. Similarly, it should be noted that the first transition portion 30A, the first support 230A, the second support 230B, and / or the second transition portion 30B can comprise the same or a different material as the material of the first portion 20.

[0060] 2 and 3, liquid management system 270 is disposed, at least in part, between first transition portion 30A and second transition portion 30B. Liquid management system 270 may include a reservoir receiver 272 and a liquid reservoir 274. As noted above, liquid reservoir 274 may be refillable or non-refillable. Also, as noted above, liquid reservoir 274 may be removably attached to reservoir receiver 272. Thus, whether liquid reservoir 274 is refillable or not, liquid reservoir 274 may be removed from reservoir receiver 272 as desired / needed and refilled and reinstalled in reservoir receiver 272 or replaced, with a different liquid reservoir attached to the reservoir receiver.

[0061] If the liquid reservoir 274 is removably attached to the reservoir receiver 272, a release member 278 may be provided to facilitate removal of the liquid reservoir 274 from the reservoir receiver 272. For example, as shown, the release member 278 may be disposed on the reservoir receiver 272. However, the release mechanism may be provided in any suitable location.

[0062] Additionally, in embodiments in which the liquid reservoir is removable, the liquid management system 270 may also include a void 276 that can facilitate a user's grip of the liquid reservoir 274. As shown, the void 276 may be disposed near the end of the liquid reservoir 274 that is most proximal to the first portion (item 20 in FIGS. 1A-2 ). However, in some embodiments, a void may be provided between the first support 230A and the second support 230B in addition to or independent of the void 276. Also, in some embodiments, the liquid reservoir 274 may be provided with a handle or indentation that facilitates a user's grip of the liquid reservoir 274.

[0063] Additionally, in configurations in which the liquid reservoir 274 is removable, one or more detents may be provided on the interior surfaces of the first support 230A and the second support 230B. These detents may help provide stability to the liquid reservoir 274 when attached to the reservoir receiver 272. The size and shape of the detents were discussed above.

[0064] If the liquid reservoir 274 is not replaceable, the first support 230A and the second support 230B may be integrally formed with the liquid reservoir 274. For example, the first support 230A and the second support 230B may form the sides of the liquid reservoir 274. Similarly, the first transition portion 30A and the second transition portion 30B may form the top and bottom of the liquid reservoir 274, respectively.

[0065] Regardless of whether the liquid reservoir is removable, the inventors surprisingly found that conventional cleaning devices do not utilize the space / volume of the second portion of the support member. Specifically, the second portion of the support member often does not perform any additional function other than as a support member. However, in the cleaning device of the present disclosure, the second portion of the support member 30 can be part of the liquid management system 270, i.e., the first support 230A and the second support 230B are integrally formed with the liquid reservoir 274.

[0066] 4, as previously mentioned, the liquid reservoir 274 has a center of gravity of its interior space located in a vertical plane 450 that is within a distance 470 from the bisecting plane 430. When the center of gravity of the interior space of the liquid reservoir 274 is outside this distance, it is believed that the cleaning device may become very difficult to operate during cleaning.

[0067] 3-5, as described with respect to FIG. 1A, a cleaning device of the present disclosure may include a handle 50. The handle 50 may include a switch 52 that activates a pump 280 that is part of a fluid management system 270. As described, if the pump is electric, the switch 52 may be in electrical communication with a power source 450, such as a battery pack. The power source 450 may also be in electrical communication with a motor that operates the pump. When activated, for example, via a depression or displacement of the switch 52, the power source 450 may provide energy to the motor. The pump may then draw fluid from the fluid reservoir 274 and deliver it to one or more nozzles / outlets on the cleaning head 40.

[0068] It is worth noting that power supply 450 may comprise a battery pack having one or more batteries. The battery pack may be rechargeable. Alternatively, power supply 450 may comprise an electrical cord that draws power from an electrical outlet.

[0069] Still other configurations are contemplated in which the pump is mechanically operated rather than electrically. In such configurations, the switch 52 may be in mechanical communication with the pump such that activation, e.g., depression or displacement, of the switch 52 operates the pump, causing liquid to be drawn from the liquid reservoir 274 and provided to one or more nozzles / outlets on the cleaning head 40.

[0070] Referring now to FIG. 6 , a schematic diagram of the cleaning head 40 is provided. As shown, the cleaning head 40 has a width 642 defined by a leading edge 675 and an opposing trailing edge 680, the width being generally parallel to the longitudinal direction. A longitudinal centerline 640 of the cleaning head may bisect the width 642 of the cleaning head 40. Additionally, as shown, a cleaning head connection portion 630 movably, e.g., pivotably, connecting the cleaning head 40 to a second portion may have a cleaning head connection centerline 632. The cleaning head connection centerline 632 may extend longitudinally relative to the cleaning head 40 through a center point of the axis of rotation, e.g., the pivot axis, of the support member. As shown, the cleaning head connection centerline 632 may be offset from the cleaning head centerline 640. The offset of the cleaning head connection centerline 632 may be toward one or more nozzles and / or outlets 670. In offsetting the cleaning head connection centerline 632 from the cleaning head centerline 640, the cleaning head 40 may be less prone to flipping over during use.

[0071] The offset of the cleaning head connection centerline 632 relative to the cleaning head centerline 640 can be based on the overall width 642 of the cleaning head 40. This offset can depend on the overall width 642 of the cleaning head 40. For example, the offset can be about 1 percent or more than the overall width 642 of the cleaning head 40, more preferably about 3 percent or more than the overall width 642 of the cleaning head 40, or most preferably about 5 percent or more, including all values ​​within these ranges and any ranges formed thereby. For example, the offset can be about 1 percent to about 15 percent of the overall width 642 of the cleaning head, more preferably about 3 percent to about 10 percent of the overall width 642 of the cleaning head, or most preferably about 5 percent to about 9 percent of the overall width 642 of the cleaning head, including all values ​​within these ranges and any ranges formed thereby.

[0072] Although not shown, the cleaning head 40 may include locking members to help hold the cleaning sheet in place. These locking members may be disposed on the upper surface 644 and / or the lower surface 646 of the cleaning head 40. Once the target surface is wetted with fluid from the liquid reservoir, the user may remove debris with the cleaning sheet. The cleaning sheet may be removably attached to the head, particularly to the underside of the head. Suitable cleaning sheets include nonwoven fabrics, microfibers, yarns, molded polymer films, superabsorbent gelling materials, compostable materials such as PLA, combinations thereof, and the like. Suitable cleaning sheets may be made in accordance with the teachings of commonly assigned U.S. Patent Nos. 6,797,357, 6,936,330, D489,537, D499,887, 5,960,508, 6,003,191, 6,048,123, 6,101,661 and / or 6,601,261.

[0073] Cleaning sheets can be disposable, i.e., discarded after becoming soiled. Disposable cleaning sheets can be discarded after a single use. Alternatively, cleaning sheets can be laundered and restored for subsequent reuse. For example, microfiber cleaning sheets can be used more than once. After subsequent reuse, durable cleaning sheets can be discarded.

[0074] Exemplary locking members include deformable grippers. Deformable grippers may be used to attach cleaning sheets because such attachments work with a variety of sheet materials, do not require extra manufacturing steps for the sheet (such as adding adhesive), and can last the life of the cleaning device. While uniform and substantially identical attachments may be used, the locking member may include two or more different attachment types. Three or more attachments may be used. If four attachments are utilized, they may be arranged in a rectangular pattern with two front attachments and two rear attachments. One or more of the attachments may be disposed on the top surface of the head and generally face away from the bottom surface of the head and the target surface during cleaning. This arrangement of the attachments provides the advantage of convenient access.

[0075] Alternatively or additionally, the locking member may comprise a hook and loop system as known in the art. The bottom of the head may be fully or partially covered with hooks. The cleaning sheet may comprise loops. By engaging the hooks with the loops, the cleaning sheet may be releasably attached to the head. If desired, the appliance may further comprise an adapter plate that allows different sizes and types of cleaning sheets to be utilized, as illustrated in commonly assigned U.S. Patent No. 6,842,936.

[0076] With respect to the one or more nozzles / outlets, any suitable nozzles / outlets may be utilized. Some examples of suitable nozzles are disclosed in U.S. Patent Nos. 5,888,006, 5,988,920, 6,206,058, 6,217,889, 6,386,392, 6,663,306, 6,722,806, and 7,172,099. When using a single nozzle, the fluid spray pattern may diverge as the fluid is released from the nozzle. The spray pattern from a single nozzle may be fan-shaped or cone-shaped. Additionally, multiple nozzles may be utilized, some suitable examples being disclosed in U.S. Pat. Nos. 3,219,276, 6,540,424, 6,595,712, 6,976,802, 7,264,413, and 8,186,898, all of which are assigned to the assignee of the present invention.

[0077] It may be useful to illuminate the floor or other target surface being cleaned. For example, the spray pattern may be illuminated and / or the floor (target surface) may be illuminated after spraying. If the target surface is simply illuminated after spraying, it is believed that an inadequate amount of spray may be applied to the target surface, which may lead to inadequate cleaning.

[0078] In one example, the light can illuminate the spray during application to the target surface. For example, an LED light can be utilized. Optionally, the light illuminates the target surface. In one particular example, the light can illuminate the target surface and the spray.

[0079] The at least one nozzle / outlet may distribute the fluid in a spray, mist, stream, fan, or other desired pattern, collectively referred to herein as a spray. Each nozzle / outlet may be oriented at a particular azimuthal angle relative to the longitudinal and / or horizontal planes. The orientation of a nozzle is determined by the orientation of its centerline. It is worth noting that the mist may provide a uniform distribution without saturating the target surface. The at least one nozzle may be disposed on each side of the longitudinal centerline and may be evenly or unevenly spaced.

[0080] The fluid sprayed from the cleaning device of the present disclosure can be any fluid that can be used to treat a target surface. Typical fluids include cleaning fluids, disinfectants, fragrances, etc. Suitable cleaning fluids can be made in accordance with commonly assigned U.S. Patent Nos. 6,380,151, 8,568,702, 8,808,678, and 10,119,102.

[0081] It is worth noting that the overall length of the cleaning device or the length of the support member may require special accommodation when offered for sale in a store. For example, many store shelves lack the vertical clearance necessary to accommodate the entire length of the cleaning device. Also, placing the cleaning device horizontally on a shelf may take up too much space relative to the shelf's length. Therefore, it is contemplated that the first and second support member portions may be disassembled within the package and require assembly before use. In such a configuration, wiring may extend from the first portion to the second portion to provide electrical communication between the actuator and the pump motor. Alternatively, in such a configuration, the first portion may include a male or female connector that mates with a complementary female or male connector on the second portion, respectively. Additionally, a detent may be provided to reduce the likelihood that the first and second portions will become separated during use.

[0082] With regard to packaging of the cleaning device of the present disclosure, the first and second portions of the support member may be disposed generally parallel. Also, if a wire extends from the first portion to the second portion, the respective ends of the first and second portions intended to be engaged during use may be positioned adjacent to each other within the package. If the first and second portions include complementary male and female connectors, the first and second portions may be positioned within the package in any suitable manner.

[0083] The dimensions and values ​​disclosed herein should not be understood as being strictly limited to the exact numerical values ​​recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean "about 40 mm."

[0084] All documents cited herein, including any cross-referenced or related patents or patent applications, and any patent applications or patents to which this application claims priority or benefit, are incorporated herein by reference in their entirety, unless expressly stated to the contrary. The citation of any document shall not be deemed to be prior art to any invention disclosed or claimed herein, or to teach, suggest, or disclose any such invention, either alone or in combination with any other reference or references. Furthermore, to the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern.

[0085] While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
