[0001] This specification relates generally to surface cleaners, and more particularly to handheld surface cleaning devices and cleaning systems implementing the same.

[Background technology]

[0003]

[0003] Vacuum cleaners and other surface devices may have multiple components that each receive power from one or more power sources (e.g., one or more batteries or electric mains). For example, a vacuum cleaner may include a suction motor that generates a vacuum within a cleaning head. The generated vacuum collects dust from the surface being cleaned and deposits the dust in a dust collector. The vacuum cleaner may also include a motor that rotates a brush roll within the cleaning head. The rotation of the brush roll agitates dust attached to the surface being cleaned so that the generated vacuum can remove the dust from the surface. In addition to the electrical components for cleaning, the vacuum cleaner may include one or more light sources to illuminate the area being cleaned.

[0004]

[0004] Vacuum cleaners generally occupy a relatively large amount of space in a closet or other storage area. For example, an upright vacuum cleaner tends to be kept in an upright position during use when stored in a remote location for future use. To this end, storage of the vacuum cleaner requires space to accommodate the overall height and width of the vacuum cleaner. This relegates vacuum cleaners to storage locations in out-of-sight areas, such as closets, garages, or secluded locations. Such locations may be some distance from rooms or other areas that require regular cleaning, and therefore these locations may be cleaned less because transporting the vacuum cleaner to and from the storage location is impractical or otherwise inconvenient.

[0007]

[0060] In general, the present disclosure is directed to handheld surface cleaning devices that include a relatively compact form factor that allows a user to store the device in a nearby location (e.g., in a drawer, in an associated charging dock, on a tabletop) for easy access to perform relatively small cleaning tasks that would otherwise require removing a full-sized vacuum cleaner from storage. Consistent with aspects of the present disclosure, a handheld surface cleaning device includes a body (or body portion) with a motor, a power source, and a dust cup disposed therein. The body portion functions as a hand grip, for example, allowing the handheld surface cleaning device to be operated with one hand. Accordingly, the body portion may be referred to as a hand grip, a handle portion, or simply a handle.

[0008]

[0061] In one embodiment, a handheld surface cleaner consistent with the present disclosure includes a body defining a handle portion and a dirty air passageway. The body may define a cavity for holding a motor for generating suction to draw dirt and dust into the dirty air passageway, a power source for powering the motor, and a dust cup for receiving and storing dirt. Each of the components within the body may be coaxially arranged. Each of the power source, motor, and dust cup may generally include a shape (e.g., substantially cylindrical, rectangular, etc.) that generally corresponds to the body of the handheld surface cleaner. Accordingly, the body may include a relatively continuous width along its length, allowing a user to comfortably grip the hand within the body during a cleaning operation. The handheld surface cleaning device also includes a cleaning head (or nozzle) that includes a longitudinal axis parallel to the body, enabling the handheld surface cleaning device to be operated in a general sense similar to the wand of a conventional full-size vacuum cleaner for cleaning without an additional bulky trailing hose and for targeting various surfaces.

[0009]

[0062] As generally referred to herein, dust and dirt means dirt, dust, water, or any other particles that can be drawn by suction into a handheld surface cleaning device.

[0010]

[0063] 1-4 illustrate a handheld surface cleaning device 100 according to an embodiment of the present disclosure. As shown, the handheld surface cleaning device 100 includes a body 102 extending along a longitudinal axis 116 from a first end 140 to a second end 142. The body 102 of the handheld surface cleaning device 100 includes a handle portion 104 adjacent the first end 140, followed by a motor portion (or section) 106, a filter portion 108, a dust cup 110, and a nozzle 114 disposed adjacent the second end 142. The body 102 may include a substantially flat and continuous surface 180 extending from the first end 140 to the second end 142, forming a "wand"-like device. In one embodiment, the handle portion 104, the motor portion 106, the filter portion 108, and the nozzle 114 may be formed as a single monolithic piece. In other cases, portions such as nozzle 114 and / or filter portion 108 may be removable.

[0011]

[0064] As shown, the handle portion 104 of the handheld surface cleaning device 100 is contoured to fit comfortably within a user's hand during operation. The tapered region 146 may advantageously allow a user's hand and fingers to more comfortably grip and manipulate the handheld surface cleaning device 100. The body 102 of the handheld surface cleaning device 100 further includes an on / off button 118 and a dust cup release button 112. The on / off button 118 and the dust cup release 112 may be actuated, for example, by the thumb of a user's hand, when the handle portion 104 is held. The dust cup release 112 may be displaced and slidably engaged, for example, by the user's thumb to unlock the dust cup 110, which will be described in more detail below. The dust cup release 112 may be spring-biased to return to a rearward position in the absence of user-supplied force.

[0012]

[0065] The motor section 106 of the body 102 may include circuitry (not shown) that selectively supplies power to a motor 126 (see FIG. 4 ) disposed therein. The motor 126 may be a DC motor or other suitable motor for generating suction. In some embodiments, the handheld surface cleaning device 100 may include a vortex array; the illustrated embodiments are not intended to limit the present disclosure. The motor 126 generates suction that draws air into the dirty air inlet 120. The amount of power supplied to the motor 126 may be varied to proportionally adjust the amount of suction. Alternatively, the on / off button 118 may simply supply a fixed amount of power to the motor 126.

[0013]

[0066] Subsequently, the dust cup 110 may be configured to receive dirt and dust received via the dirty air inlet 120. As shown, the dust cup 110 is rotatably coupled to the body 102, and more specifically, to a portion of the dirty air inlet 120, via a hinge 149, which is formed by a pin that extends substantially through the body 102 and is oriented substantially transverse to the longitudinal axis 116. The nozzle 114 may provide the hinge 149. In some cases, the nozzle 114 may be removable. Thus, the dust cup 110 may rotate along a first axis of rotation, for example, when released via the dust cup release 112. For example, as shown in FIG. 3, the dust cup 110 may rotate in a direction generally designated D and stop at an angle of approximately 90 degrees relative to the longitudinal axis 116 of the body 102. This position of the dust cup 110 may be accurately referred to as an open, release, or discard orientation. In the open orientation, the opening 148 may be used to allow, for example, dust and debris to exit the dust cup 110 and enter a trash can. Thus, the dust cup 110 may transition between, for example, a locked / closed orientation as shown in FIG. 1 and an open / discard orientation as shown in FIG. 3. When in the closed orientation, the dust cup 110 is in fluid communication with the filter of the filter section 108 via the opening 148. However, when in the open orientation, the dust cup 110 is disconnected from fluid communication with the filter of the filter section 108, and the opening 148 allows dust and debris accumulated within the dust cup 110 to be released / exhausted.

[0014]

[0067] As discussed further below, the dust cup 110 may include cleaning or agitating elements (e.g., bristles) that agitate the filter within the filter section 108. Agitation of the filter within the filter section 108 frees trapped / clogged dirt and dust and generally promotes increased air fluid communication to ensure that clogging is minimized or otherwise reduces suction power.

[0015]

[0068] Figure 4 shows an exemplary cross-sectional view of the handheld surface cleaning device 100 taken along line 4-4 of Figure 1. As shown, the body 102, and particularly the handle portion 104, defines a cavity 150 that can accommodate one or more power sources, such as batteries. The cavity may include a battery holder 128 or battery cradle 128 for positioning and aligning the battery with associated electrical contacts (not shown) for electrically coupling the battery to the motor 126. As mentioned above, the handle portion 104 provides a tapered region 146, which provides a transition between the handle portion 104 and the motor section 106.

[0016]

[0069] Continuing, the cavity 150 defined by the body 102 continues through the motor section 106. The motor section includes a motor 126 disposed within the cavity 150. After the motor section, the cavity 150 continues through the filter section 108. The filter 124 can then be disposed within the cavity 150 of the filter section. As shown , filter 124 is a cone-type filter, although other filter devices are within the scope of this disclosure. Thus, cavity 150 may extend from a first end 140 at the base of handle portion 104 to a second end via dirty air inlet 120.

[0017]

[0070] Adjacent the filter section 108, a dust cup 110 couples to the filter 124. The dust cup 110 may thus be fluidly coupled to the filter section 108 by way of an opening 148. A screen 154 (see FIG. 6) may cover the opening 148 to prevent dirt and debris from entering the motor section 106, which will be described in more detail below. As further shown, a dirty air inlet 120 is in fluid communication with the dust cup 110 for the purpose of receiving and storing dirt and debris.

[0018]

[0071] A valve body 122 formed from a flexible or resilient material may be positioned between the dust cup 110 and the dirty air inlet 120. When the suction provided by the motor 126 is not being forced, the valve body 122 may remain in a valve seating position, as shown in FIG. 4 . The valve body 122 may be biased toward the dirty air inlet 120 based on spring tension, for example, based on a bend introduced into the material, or other suitable arrangement. The seating position of the valve body 122 may form a seal, e.g., an airtight seal that prevents 100% of air flow, or a partial airtight seal that restricts at least 80% of air flow, between the openings of the dust cup 110 that are aligned with the openings of the dirty air inlet 120, generally indicated at 170. Thus, the seating position of the valve body 122 may prevent dust and debris from exiting the dust cup 110 through the openings aligned with 170 when the surface cleaning apparatus 100 is “off,” e.g., when suction from the motor 126 is not present. The valve body 122 may be configured to be displaced / bend into the cavity 152 of the dust cup 110 when the suction force generated by the motor 126 draws air into the dirty air inlet and ultimately into the dust cup 110.

[0019]

[0072] In one embodiment, when the dust cup 110 is in the release orientation, as shown in FIG. 3, for example, the valve body 122 in the seated position continues to seal the cavity of the dust cup 110, for example, based on a spring force that biases the valve body 122 away from the dust cup 110, holding the cavity of the dust cup 110 against one or more defined surfaces, and ensuring that dust and debris can only exit the dust cup 110 through the opening 145.

[0020]

[0073] Referring to FIG. 5, there is another exemplary embodiment of a dust cup suitable for use with the handheld surface cleaning device 100 of FIGS. 1-4. As shown, the dust cup includes an agitator member 155 in the form of a plurality of bristles. The bristles may be formed, for example, from plastic or another suitably rigid material. When in the closed position as shown in FIG. 6, the bristles 155 may be disposed adjacent to the top surface 180 of the body 102 of the handheld surface cleaning device 100. As shown in the cross-sectional view of FIG. 6, the agitator member 155 contacts the screen 154 of the filter section 106 as the dust cup 110 rotates about the axis 160 to transition from the closed orientation to the open orientation. The screen 154 and the filter 124 may be collectively referred to herein as the filter arrangement. This contact, in a general sense, "scrapes" the screen 154, advantageously removing or displacing dust adhering to the screen 154, which may minimize or reduce loss of suction between the motor, filter, and dirty air inlet 120.

[0021]

[0074] The same scrubbing action can be achieved when transitioning the dust cup 110 from an open orientation to a closed orientation. To this end, each cleaning operation of the dust cup 110 performed by a user can result in a two-stage cleaning action. Hereby, a first stage involves scrubbing the screen 154 along a first direction D1 when the dust cup 110 is released. A second stage involves scrubbing the screen 154 along a second direction D2 when the dust cup 110 transitions to a closed position (see FIG. 7). In some cases, a user can release and close the dust cup 110 multiple times, with the two-stage cleaning action clearing obstructions.

[0022]

[0075] 7, the filter section 106 may include a removable filter carriage 107 to allow the filter 124 to be replaced or otherwise cleaned. As shown, this embodiment includes the dust cup 110 being in a release orientation prior to removal of the removable filter carriage 107. Alternatively, or additionally, the entire filter carriage 107 and filter 124 may be replaced as a single, easy-to-use unit.

[0023]

[0076] 8 illustrates an example of a vacuum cleaner 800 configured to removably couple to a handheld surface cleaning device 1. The handheld surface cleaning device 1 may be implemented as the handheld surface cleaning device 100 of FIG. 1, and this disclosure is not intended to be limited in this respect. As shown, the vacuum cleaner 800 includes a vacuum frame 802 (or simply frame 802), a foldable joint 804, a handheld surface cleaner receptacle 806, a dust cup receptacle 808, a removable dust cup 810, and a cleaning head 812 with a dirty air inlet 814.

[0024]

[0077] Frame 802 defines a handheld surface cleaner receptacle 806, or handheld receptacle, configured to securely hold handheld surface cleaning device 1. When handheld surface cleaning device 1 is placed / mounted within handheld receptacle 806, dirty air inlet 120 can be aligned with and in fluid communication with a dirty air channel (not shown) that fluidly couples dirty air inlet 814 with dust cup 810. Thus, suction generated by the motor of handheld surface cleaning device 1 can be used to draw air into dirty air inlet 814. From there, dirt and dust can then be stored within dust cup 810 (or first dust cup) and / or dust cup 110 (or second dust cup) of handheld surface cleaning device 1.

[0025]

[0078] In some cases, the presence of dust cup 810 effectively increases (e.g., more than doubles) the overall storage capacity for dust and dirt compared to using dust cup 110 alone, although in some embodiments, dust cup 110 may be utilized exclusively. Also shown, frame 802 includes an optional foldable joint 804 that allows an upper handle portion of frame 802 to be bent parallel to a lower portion having a hand-holding receptacle 806 for storage purposes (see also FIGS. 34A-34C).

[0026]

[0079] 9 shows an embodiment of a dust cup 810 having a door 850 that can be hinged to the body 840 of the dust cup 810. In this example, a button can be pressed to release the door 850, allowing it to swing / swivel open and allow stored dirt and debris to exit the body 840 of the dust cup 810.

[0027]

[0080] 10 illustrates an exemplary embodiment of a docking system 4400 including a dock 4401, a handheld surface cleaning device 4402, and a robotic vacuum cleaner 4403. In one embodiment, the handheld surface cleaning device 4402 is implemented as, for example, the handheld surface cleaning device 100 of FIG. 1 or the handheld surface cleaning device 1 of FIG. 21. As shown, the dock 4401 includes a robotic vacuum cleaner coupling section defined at least in part by a base 4404, which is configured to removably couple to the robotic vacuum cleaner 4403. The base 4404 may further include electrical contacts / terminals for electrically coupling with the robotic vacuum cleaner 4403 for recharging purposes.

[0081] The dock 4401 further includes a handheld surface cleaning device coupling section 4405, which may simply be referred to as a wand coupling section. The wand coupling section 4405 may include a wand receptacle 4406 and a wand release 4410 (or wand release pedal 4410). As shown in the exemplary embodiment of FIG. 11 , the wand receptacle 4406 (or receptacle) may be a recess / opening defined by a sidewall of the wand coupling section 4405. The wand receptacle 4406 may extend substantially perpendicular to a longitudinal axis 4408 of the dock 4401. The wand receptacle 4406 may be configured to at least partially receive the handheld surface cleaning device 4402. As shown, the wand receptacle 4406 includes a depth that allows the top surface 4409 of the handheld surface cleaning device 4402 to be mounted flush with the surface 4401 that defines the wand receptacle 4406. Thus, the handheld surface cleaning device 4402 may be relatively concealed when mounted in the wand receptacle 4406, and may have a contour that generally corresponds to the shape of the wand coupling section 4405.

[0029]

[0082] Inserting the handheld surface cleaning device 4402 into the wand receptacle 4406 may include inserting the handheld surface cleaning device 4402 at a first angle, for example, approximately 80 degrees. The nozzle of the handheld surface cleaning device 4402 is used to bias and engage a spring-loaded mechanism (not shown). Once inserted, the handheld surface cleaning device 4402 may be locked in place via a detent (not shown) or other suitable locking mechanism.

[0030]

[0083] To remove the handheld surface cleaning device 4402, a user-provided force (e.g., by the user's foot or hand) applied to the wand release 4410 releases the locking mechanism, allowing the spring-loaded mechanism to transition the handheld surface cleaning device 4402 from the retracted position to the extended / release position. As shown, this transition may involve the handheld surface cleaning device 4402 rotating about a first axis of rotation 4412 that extends substantially parallel to the longitudinal axis 4408. In the release position, the user can simply grasp the handheld surface cleaning device 4402 and apply a force vertically away from the wand receptacle 4406 to separate it for use.

[0031]

[0084] FIG. 11 shows another exemplary embodiment of a docking system 4400a consistent with the present disclosure. The embodiment of FIG. 11 may also be accurately referred to as an upright configuration, but here the handheld surface cleaning device 4402 extends vertically from the dock 4401a. More specifically, the dock 4401a includes a base 4404a and a wand coupling section 4405a. The base 4404a includes release buttons 4501 and 4502. The release buttons 4501 and 4502 may enable separation of the robotic vacuum cleaner 4403 and the handheld surface cleaning device 4402, respectively, based on user-supplied force (e.g., from the user's foot). As shown, the release buttons 4501 and 4502 may at least partially define an incline along which the robotic vacuum cleaner may move to be coupled to the dock 4401a.

[0032]

[0085] The wand coupling section 4405a may include a wand receptacle 4406a configured to at least partially receive the handheld surface cleaning device 4402. In particular, the wand receptacle 4406a may include an elongated cavity having a longitudinal axis that may extend substantially perpendicular to the longitudinal axis of the handheld surface cleaning device 4402. In this manner, a handle section / region of the handheld surface cleaning device 4402 may extend at least partially from the wand receptacle 4406a when in the stored position.

[0033]

[0086] The wand coupling section 4405a may include a taper adjacent the robot vacuum cleaner coupling section, providing a recess for at least partially receiving the robot vacuum cleaner. Thus, the taper may form at least a portion of the robot vacuum cleaner coupling section. When the robot vacuum cleaner 4403 is coupled to the base 4404a, at least a portion 4503 of the wand coupling section 4405a may extend above the robot vacuum cleaner 4403. This may advantageously reduce the overall footprint of the docking system 4400a when the robot vacuum cleaner is in the stored position (i.e., coupled to the base 4404a).

[0034]

[0087] The user may then grasp the handle section / region of the handheld surface cleaning device 4402 and apply a force generally along direction D2 to separate it from the wand receptacle 4406a. In some cases, the user may first need to engage the release button 4502 to unlock the handheld surface cleaning device 4402 from the wand receptacle 4406a. Additionally, the wand receptacle 4406a may include a spring-loaded mechanism that moves the handheld surface cleaning device 4402 upward along direction D2 in response to the user applying a force to release the release button 4502 while remaining at least partially within the wand receptacle 4406a. Direction D2 may extend substantially perpendicular to the longitudinal axis 4408a of the dock 4401a. This may advantageously reduce how far the user must reach to grasp the handheld surface cleaning device 4402.

[0035]

[0088] 12 shows another exemplary embodiment of a docking system 4400b in an upright configuration consistent with the present disclosure. As shown, this embodiment is substantially similar to that of docking system 4400a, and for the sake of brevity, its description will not be repeated. However, the docking system of 4400a includes a wand receptacle 4406b that does not have a locking mechanism and may instead utilize a friction fit or simply gravity. Thus, the handheld surface cleaning device 4402 can be inserted / removed from the dock 4401b without actuating a release, such as release button 4502 (FIG. 11).

[0036]

[0089] 13a-13d illustrate another exemplary embodiment of a docking system 4400c consistent with aspects of the present disclosure. As shown, the docking system 4400c includes a dock 4401c, a handheld surface cleaning device 4402, and a robotic vacuum 4403. The dock 4401c includes a base 4404b that defines a robotic vacuum coupling section. The wand coupling section 4401c includes a fixed portion 4703 rotatably coupled to a wand receptacle 4407b by a hinge 4702. Accordingly, the wand receptacle 4407b may rotate about a second axis of rotation 4412a between a retracted position (FIGS. 13c-d) and a released position (FIG. 47a), each of which is discussed in more detail below.

[0037]

[0090] 13-13d, the wand receptacle 4407b may at least partially surround the handheld surface cleaning device 4402. In a general sense, the wand receptacle 4407b may form a cradle that holds the handheld surface cleaning device 4402 in a fixed position based on a friction fit connection, gravity, or both.

[0038]

[0091] As shown in Figure 13a, when the wand receptacle 4407b is in the released position, the wand receptacle 4407b extends at approximately 45±20 degrees relative to the longitudinal axis 4408b of the base, thereby allowing a user to easily reach and grasp the handheld surface cleaning device 4402. On the other hand, when the wand receptacle 4407b is in the retracted position as shown in Figure 13c, the wand receptacle 4407b extends substantially parallel to the longitudinal axis 4408b of the base.

[0039]

[0092] In one embodiment, the wand receptacle 4407b may transition between the retracted and released positions via a hinge 4702 or other suitable coupling device that allows rotation about the second axis of rotation 4412a. The dock 4401c may include a mechanical mechanism (e.g., a gear, belt drive, or other suitable mechanism) that causes rotation of the wand receptacle 4407b between the retracted and released positions. The fixed portion 4703 may include a proximity sensor 4711, such as an infrared (IR) sensor. The proximity sensor 4711 induces a vertical IR field that, if violated by a user's hand (or other part), causes the wand receptacle 4407b to automatically rotate to the released position, allowing for easy removal of the handheld surface cleaning device 4402. The released position may also reveal or otherwise provide access to controls on the top surface of the robotic vacuum cleaner 4403 (see FIGS. 14a-c).

[0040]

[0093] 14a-14c show the embodiment of Figures 13a-13d in additional detail. As shown, the dock 4401c may include an elongated leg 4802 that extends from the fixed section 4799 to a distance D1 that is at least 1.5 times the height H2 of the fixed section 4799. The elongated leg 4802 may thus advantageously support the wand receptacle 4407b (and handheld surface cleaning device 4402) in the absence of the robotic vacuum cleaner 4403.

[0041]

[0094] FIG. 15 illustrates another embodiment of a docking system 4400d consistent with aspects of the present disclosure. The docking system 4400d is similar to that of the docking system 4400a (FIG. 11), the disclosure of which will not be repeated for brevity. As shown, the wand coupling section 4405b includes an IR sensor (or other suitable proximity sensor), a wand receptacle 4407c having a tooth / detent (not shown), and an elevator / extension mechanism. The IR sensor may emit an IR beam adjacent to the dock 4401d. If the IR beam is violated (e.g., by a user's hand), a signal may be sent to the elevator / extension mechanism, causing it to extend upward along vertical direction D3. The tooth / detent may engage a guide / track disposed along the length of the handheld surface cleaning device 4402, allowing it to move vertically along a relatively straight path. In one embodiment, this may cause the handheld surface cleaning device 4402 to elevate 6 to 8 inches, although other configurations are within the scope of the present disclosure. The IR sensor may further include a visual indicator (eg, an LED) to draw the user's attention to the sensor's location.

[0042]

[0095] 15, the wand coupling section 4405b may be tapered (as shown in side profile) to offset the wand receptacle 4407c from the adjacent wall by a distance D4. This may advantageously allow a user to more easily reach around the handheld surface cleaning device 4402, even when the dock 4401d is positioned flush against a wall.

[0043]

[0096] 16a-16c collectively illustrate another embodiment of a docking system 4400e consistent with aspects of the present disclosure. As shown, the dock 4401e includes a wand receptacle 4407d adjacent a first end 5001 of the dock 4401e. As shown, the wand receptacle 4407d is integrally formed with the dock 4401e as a single monolithic piece. However, the wand receptacle 4407d and the dock 4401e may be formed as separate pieces depending on the desired configuration. The wand receptacle 4407d may include a curvilinear profile / shape to increase aesthetic appeal and to form a shape that generally corresponds to the shape of the handheld surface cleaning device 4402.

[0044]

[0097] As shown, the orientation of the wand receptacle 4407d is fixed. The handheld surface cleaning device 4402 disposed therein is held at an angle of approximately 45 degrees relative to the top surface 5002 defining the dock 4401e. Other brush types are within the scope of this disclosure. The embodiment of FIGS. 16a-16c may accurately be referred to as a side-by-side configuration, whereby the wand receptacle 4407d is adjacent (e.g., positioned laterally) to the area where the robotic vacuum cleaner couples to the dock 4401e. Thus, when inserted into the wand receptacle 4407d, the handheld surface cleaning device 4402 includes a longitudinal centerline 4408d that is horizontally offset a distance D5 from the centerline 4408e of the robotic vacuum cleaner drawn against the dock 4401e, the distance D5 being at least equal to the radius R1 of the robotic vacuum cleaner.

[0045]

[0098] FIG. 17 illustrates another embodiment of a docking system 4400f consistent with aspects of the present disclosure. As illustrated, the embodiment of FIG. 51 is similar to that of docking system 4400e of FIG. 50, and for this reason, a description will not be repeated for brevity. As shown, dock 4401f includes a wand coupling section 4405c including a robot coupling section 4420c and a wand receptacle 4407e in a side configuration. Wand coupling section 4405c further includes an IR sensor 5102 (or other suitable proximity sensor). In response to a user interfering with the IR beam emitted by IR sensor 5102, a signal can be transmitted to wand receptacle 4407e. A lift and tilt mechanism (not shown) can then receive the signal and transition handheld surface cleaning device 4402 from the stowed position 5105 to the released position 5106. As shown, transitioning to the release position 5106 causes the handheld vacuum cleaner 4402 to initially move along a vertical path relative to the top surface of the robotic vacuum cleaner (e.g., away from the robotic vacuum cleaner). The handheld vacuum cleaner 4402 is then "tilted" towards the robotic vacuum cleaner, e.g., at an angle of approximately 70±15 degrees relative to the robotic vacuum cleaner. Meanwhile, transitioning to the stowed position 5105 causes the reverse of the transition to the release position 5106, e.g., tilting back vertically and then moving downward towards the robotic vacuum cleaner.

[0046]

[0099] If no user is detected, for example when the user moves away from the dock 4401f, the lift and tilt mechanism may automatically transition the handheld surface cleaning device back to the storage position 5105. This advantageously allows the user to insert the handheld surface cleaning device 4402 into the wand receptacle 4407e and simply move away, while the wand receptacle 4407e moves back to the storage position 5105.

[0047]

[0100] The following additional embodiments and examples are equally applicable to the present disclosure. For example, the handheld surface cleaning device 1 of Figure 21 may be utilized in various embodiments disclosed above, including, for example, a base (see Figures 10-20b) that may be utilized to couple to both robotic and handheld cleaning devices.

[0048]

[0101] FIG. 21 shows a perspective view of a handheld surface cleaning device 1 according to an embodiment of the present disclosure. As shown, the handheld surface cleaning device 1 includes a body 2 coupled to a cleaning head 3. An optional flexible region 4, also referred to as a flexible conduit, couples the body 2 to the cleaning head 3 and allows the cleaning head 3 to rotate relative to the body 2 during a cleaning operation. A dirty air passageway 14 can extend from a dirty air inlet 11 provided by the cleaning head 3, through the cleaning head 3 and the body 2, to a dust cup 23 (see FIGS. 22A and 22B) positioned adjacent the distal end of the body relative to the cleaning head 3. Thus, the body 2 and the cleaning head 3 can be in fluid communication to receive dirt and dust via the dirty air passageway.

[0049]

[0102] The body 2 extends along a first longitudinal axis 9 from a first end 10-1 to a second end 10-2. The body 2 may have a substantially cylindrical shape as shown, although other shapes (e.g., rectangular, square, irregular, etc.) and configurations are within the scope of this disclosure. The body 2 may be formed from plastic or other suitably rigid material. The body 2 may include multiple pieces or may be formed from a single piece. As shown, the body 2 includes a removable piece for separating the dust cup portion 6 from the power supply and motor portion 8.

[0050]

[0103] The body 2 may be defined by a surface 5, also referred to as a handgrip surface 5. The body 2 may be contoured to comfortably fit a user's hand during use. Thus, the handgrip surface 5 may extend at least partially around the power supply and motor portion 8 and the dust cup portion 6.

[0051]

[0104] The body 2 may include a power supply and motor portion 8 disposed proximate the first end 10-1, followed by the dust cup portion 6. As discussed in more detail below, the components within the power supply and motor portion 8 (e.g., one or more motors and one or more power sources, such as batteries) may be disposed coaxially with the dust cup portion 6 of the body 2. Because the power supply and motor portion 8 is disposed forward (e.g., upstream) of the dust cup portion 6, the components of the power supply and motor portion 8 collectively define a cavity extending therethrough, allowing dirty air traveling along the dirty air passage 14 to reach the dust cup portion 6 for storage purposes.

[0052]

[0105] The body 2 may include vents 7 located proximal to the second end 10-2 to allow filtered / cleaned air to exit the body 2. The vents 7 may be located proximal to the second end 10-2 to ensure that a user's hands do not inadvertently cover the vents 7 during operation. Other locations for the vents 7 are within the scope of this disclosure, and the example illustrated in FIG. 21 should not be construed as limiting.

[0053]

[0106] Continuing with FIG. 21 , the cleaning head 3 may extend along a second longitudinal axis 15 from a first end 12-1 to a second end 12-2. The cleaning head 3 may be formed from the same material as the body 2, or may comprise a different material. In some cases, the cleaning head 3 is formed from a bendable material, e.g., a material that bends / does not bend based on a user-supplied force. In other cases, the cleaning head 3 is formed from a relatively rigid material that resists bending. In still other cases, the cleaning head 3 is formed from multiple materials. For example, the first end 12-1 adjacent the dirty air inlet 11 may be formed from a relatively rigid material, and the second end 12-2 may be formed from a relatively rigid material.

[0054]

[0107] In some cases, the first longitudinal axis 9 of the body 2 may be substantially parallel to the second longitudinal axis 15, for example, for storage purposes, docking purposes, or if a user desires the cleaning head 3 to extend straight out from the body 2. In other cases, as shown, the second longitudinal axis 15 of the cleaning head 3 may extend at an angle 17 relative to the first longitudinal axis 9, the angle 17 being between 1 and 180 degrees, preferably between 30 and 90 degrees.

[0055]

[0108] As further shown, the dirty air inlet 11 is disposed at the first end 12-1. The dirty air inlet 11 may define an opening having a width W1 and a height H1. The ratio of W1 to H1 may measure, for example, approximately 2:1, 3:1, 4:1, 10:1, or 15:1, including all ranges therebetween. The ratio of the overall length L1 to the width W1 may measure approximately 1:1, 1.25:1, 1.5:1, or 2:1, including all ranges therebetween. Other ratios are within the scope of this disclosure, and the examples provided are not intended to be limiting. The width W1 of the dirty air inlet 11 may be greater than the width W2 of the cleaning head 3 proximal to the second end 12-2. Thus, the cleaning head 3 may taper inwardly from the first end 12-1 to the second end 12-2. However, the cleaning head 3 need not necessarily be tapered as shown and may include a substantially continuous width along the longitudinal axis 15.

[0056]

[0109] The handheld surface cleaner may further include a flexible region 4 (or flexible conduit) disposed between the main body 2 and the cleaning head 3. In particular, a first end of the flexible region 4 may be coupled to a second end 12-2 of the cleaning head 3. A second end of the first end of the flexible region 4 may be coupled to a first end 10-1 of the main body 2. The flexible region 4 may include a cavity that defines at least a portion of the dirty air passageway 14.

[0057]

[0110] The flexible region 4 may be formed from plastic or other bendable material that can bend based on a user-supplied force. The flexible region 4 may be configured to return to a particular resting state in the absence of a user-supplied force. For example, the flexible region 4 may return to an unbent state in which the first and second longitudinal axes 9 and 15 of the body 2 and cleaning head 3 extend substantially parallel. In other cases, the flexible region 4 may be configured to remain in a bent position, for example, via a clip or other mechanical retention feature, until a user supplies a force to move the cleaning head to another position relative to the body 2.

[0058]

[0111] In either event, the flexible region 4 allows the cleaning head 3 to rotate relative to the body 2. In some cases, as noted above, the flexible region 4 may allow for an angle 17 measuring between 0 and 180 degrees. Preferably, the flexible region 4 allows for a maximum rotation of 90 degrees.

[0059]

[0112] In some cases, rotation of the cleaning head 3 relative to the main body 2 switches the handheld surface cleaner on. For example, when a user wants to clean a particular surface, the user can automatically turn on the handheld surface cleaner 1 by simply engaging the cleaning head 3 with the surface and applying force that causes the flexible region 4 to bend. In response to the bending of the flexible region 4, the handheld surface cleaner 1 may apply power to the motor to induce suction along the dirty air passage 14. Similarly, the absence of force applied by the user switches the handheld surface cleaner 1 off.

[0060]

[0113] Alternatively, or in addition to the auto-on feature described above, the main body 2 may include a button or other suitable control (not shown) that allows the handheld surface cleaner 1 to be manually turned on and off.

[0061]

[0114] It should be noted that the flexible region 4 is optional. For example, the body 2 may simply be directly coupled to the cleaning head 3. Alternatively, the flexible region 4 may also be replaced with a rigid portion (or rigid conduit) that does not bend based on user-supplied force.

[0062]

[0115] In any such case, the body 2 and / or cleaning head 3 may be removably coupled to the flexible region 4. Thus, a user may remove the body 2 and / or cleaning head 3 from the flexible region 4 to, for example, prevent clogging of the dirty air passage 14, or to attach a different type of cleaning head 3, such as a cleaning head made up of brush bristles.

[0063]

[0116] Referring to FIG. 22A , in accordance with an embodiment of the present disclosure, the body 2 is shown separated from the cleaning head 3 and the flexible region 4. The body 2 is shown in greatly simplified form, and other components may be disposed within the body 2. As shown, the body defines a cavity 19. The body 2 further includes a motor 20, a power source 22, and a dust cup 23 disposed within the cavity 19. The motor 20, the power source 22, and the dust cup 23 may each include a longitudinal axis substantially parallel to the longitudinal axis 9. Thus, the motor 20, the power source 22, and the dust cup 23 may be coaxially disposed within the cavity 19. As described below, this coaxial arrangement allows the motor 20, the power source 22, and the dust cup 23 to collectively form a single dirty air passageway, such as the dirty air passageway 14, with their respective cavities aligned. The coaxial arrangement may form multiple dirty air passageways depending on the desired configuration, and the present disclosure should not be construed as limited to a single passageway.

[0064]

[0117] The motor 20 may include, for example, a brushless DC motor, although other types of motors are within the scope of this disclosure. The motor 20 may be electrically coupled to a power source 22 and / or an AC line via a charging circuit, as discussed further below. The motor 20 may include a cavity 52 (see FIG. 23C) to allow the dirty air passage 14 to extend therethrough. The motor 20 may include an impeller / fan 50 that directs airflow / suction toward the dust cup 23.

[0065]

[0118] 23C and 23B show motor 20 in further detail according to an embodiment of the present disclosure. As shown, motor 20 may be constructed within fan 50 disposed within cavity 52. ​​Motor 20 further includes openings / vents 51 along sidewalls 53 to regulate airflow.

[0066]

[0119] Returning to FIG. 22A , the power source 22 can include a plurality of battery cells 29. In one embodiment, each battery cell is a lithium-ion battery cell, although other types of battery cells are within the scope of this disclosure. As shown in FIG. 23A , the plurality of battery cells 29 can each form an annular arrangement. The annular arrangement can include a cavity 32 extending therethrough. In the annular arrangement, each battery cell can have a respective longitudinal axis substantially parallel to the longitudinal axis 9 of the body 2 when the power source 22A is disposed therein. FIG. 23B shows another exemplary power source 22B configured as a ring-shaped capacitor. The ring-shaped capacitor can also include a cavity 33 extending therethrough. In such a case, the power source 22 can at least partially define the dirty air passage 14 based on the associated cavity. Thus, a cavity of the power source 22, such as cavity 32 or 33, can be aligned with the motor cavity 52 when the power source 22 and cavity 52 are disposed within the cavity 19 of the body 2.

[0067]

[0120] Returning to FIG. 22A , power supply 22 may be charged via an associated charging circuit (not shown). The charging circuit may include, for example, an induction coil for receiving an electrical charge for purposes of charging power supply 22. Alternatively, or additionally, the charging circuit may include a terminal or other suitable interconnection (e.g., a USB-C port), for example, to couple to a base / docking station for charging purposes. The charging circuit may also allow power from the mains to be used directly by handheld surface cleaning device 1 while charging power supply 22.

[0068]

[0121] Figure 22B shows a body 2' of substantially similar configuration to that of body 2 of Figure 22. For this reason, the foregoing description is equally applicable to body 2' and will not be repeated for the sake of brevity. However, body 2' includes a power source 22 located before motor 20. Thus, body 2' includes power source 22 located proximate first end 10-1 of body 2, followed by motor 20, followed by dust cup 23.

[0069]

[0122] The bodies 2 and 2' of Figures 22A and 22B, respectively, may include multiple power sources 22 and / or multiple motors 20 disposed and aligned within the cavity 19 to form the dirty air passageway 14. Thus, while the above examples illustrate a single motor and power source, the disclosure is not limited in this regard. Similarly, while each motor, power source, and dust cup has a substantially cylindrical shape, the disclosure is not limited in this regard. Other shapes and configurations are within the scope of the disclosure.

[0070]

[0123] 23C-23D, the dust cup 23 may be configured to receive and store dust and debris received from the dirty air passage 14. The dust cup may define a cavity 40 for storing the dust and debris. The dust cup may further include an electrostatic charge accumulator 41 that serves to attract and capture the dust and debris. In some cases, the electrostatic charge accumulator 41 is formed from a material that naturally tends to hold a static charge. Alternatively, or additionally, the electrostatic charge accumulator 41 may be energized, for example, via the power source 22.

[0071]

[0124] 24A-24C illustrate additional exemplary embodiments consistent with the present disclosure. As shown in FIG. 24B, the handheld surface cleaning device can be docked to a base for recharging purposes.

[0072]

[0125] Figure 25 shows an exemplary handheld surface cleaning device consistent with the present disclosure. Figure 26A shows a cross-sectional view of the handheld surface cleaning device of Figure 25 according to an embodiment of the present disclosure. Figure 26B shows an exemplary cleaning head of the handheld surface cleaning device of Figure 25 according to one embodiment of the present disclosure. Figure 26C shows an exemplary handle of the handheld surface cleaning device of Figure 25 according to one embodiment of the present disclosure.

[0073]

[0126] 27 illustrates another exemplary handheld surface cleaning device consistent with the present disclosure. As shown in FIG. 27, the handle portion may rotate relative to the body to transition / articulate into one or more positions. The battery may be located within the handle portion as shown in cross section along AA, which allows the handle portion to have a relatively low form factor throughout its length.

[0074]

[0127] 28A-28C illustrate additional exemplary embodiments of a surface cleaning device consistent with embodiments of the present disclosure.

[0075]

[0128] 29A-29H show additional exemplary embodiments of a surface cleaning device consistent with embodiments of the present disclosure. As shown, a handheld surface cleaning device consistent with the present disclosure may include an arrangement for wiping / removing dust during the dust cup emptying procedure.

[0076]

[0129] 30A-30C illustrate additional exemplary embodiments of a surface cleaning device consistent with embodiments of the present disclosure. As shown, the dust cup can be extended to increase storage capacity.

[0077]

[0130] 31A-31D, an exemplary surface cleaning apparatus 1300 is shown in accordance with an embodiment of the present disclosure. As shown, the surface cleaning apparatus 1300 includes a body 1301 and a dust cup 1302 coupled to a first end 1319 of the body 1301. Aspects and embodiments described above with reference to FIGS. 1-20B and 21-30C equally apply to the surface cleaning apparatus 1300 and will not be repeated for the sake of brevity.

[0078]

[0131] As generally referred to herein, the terms "closed position" and "docked position" may be used interchangeably and refer to the position of the dust cup 1302 relative to the body 1301, whereby the dust cup 1302 is coupled to and in fluid communication with the body 1301, and more particularly, the motor 1322 disposed within a cavity in the body 1301 that generates suction to draw dirt and debris into the dust cup 1302. In some cases, the closed position may result in the dust cup 1302 having a longitudinal axis that extends substantially parallel to the longitudinal axis of the body 1301, as shown in FIG.

[0079]

[0132] Conversely, the terms "open position" and "empty position" are used interchangeably and refer to the position of the dust cup 1302 relative to the body 1301, whereby the dust cup 1302 is tilted substantially perpendicular to the body 1301 to allow emptying of the dust cup. The dust cup 1302 may be rotatably / pivotally coupled to the body 1301 such that the dust cup 1302 can be transitioned to the open position. This transition may be initiated, for example, by a button 1305 located on the body 1301, which is discussed in more detail below. Thus, when in the open position, the dust cup may be fluidly isolated from the motor 1322, while remaining pivotally and rotatably coupled to the housing.

[0080]

[0133] As discussed in more detail below, the dust cup 1302 may be spring-loaded to deflect / bring it to the open position. The body 1301 may provide a stop, such as a sidewall 1340 ( FIG. 31B ), or other surface feature, to engage with the dust cup 1302 during rotation upon release of spring tension. Engaging the stop then causes the dust cup 1302 to abruptly stop its rotational motion, an impact that advantageously dislodges dirt and debris stored within the dust cup 1302. Gravity may then be used to dislodge the dirt and debris from an opening in the dust cup located at the opposite end from the inlet opening that receives dirty air. The spring bias may then hold the dust cup 1302 in the open position until the user desires to transition the dust cup 1302 back to the closed position. Thus, a user can empty the dust cup 1302 by simply tilting the handheld surface cleaning device 1300 over the opening of a dustbin and transitioning the dust cup 1302 to an open position, for example, via actuation of the button 1305.

[0081]

[0134] Additionally, and according to an embodiment, the filter arrangement 1314 may be at least partially disposed within the body 1301. The filter arrangement 1314 may also be spring loaded and "deflected" forward (see FIGS. 31B and 31D) to extend at least partially from the body 1301 and stop at a predetermined distance D1. In this embodiment, the filter arrangement 1314 may move a distance D1 from the body 1301 (after the dust cup 1302 rotates away from the filter arrangement 1314) before encountering a stop, such as a wrap, catch, or other protrusion on the interior or exterior of the body 1301, such as protrusion 1398 (see FIG. 31B). The spring bias may then hold the filter arrangement 1314 in the extended position until the dust cup 1302 displaces the filter arrangement 1314 when it returns to the closed position, for example, based on a user-provided force.

[0082]

[0135] Thus, the surface cleaning device 1300 can be accurately described as having a multi-phase (or multi-stage) opening sequence based on a single user-supplied motion. In response to a single user-supplied motion (e.g., pressing a button), the dust cup first snaps / springs / actuates forward (longitudinally), then rotates to a vertical / upright position, and then the filter arrangement snaps / springs out simultaneously with or shortly after the dust cup transition (e.g., based on the spring of the filter arrangement 1314 having a different spring constant / configuration than the spring associated with the dust cup 1302). Notably, the dust cup 1302 can be weighted to trigger the upright position (see FIG. 31B). Alternatively, or additionally, the dust cup 1302 can be brought to the upright position based on a track provided by the rotating body 1301. It should be noted that the dust cup 1302 may be configured with an agitation device, e.g., bristles, similar to those of the dust cup 110 of FIG. 5, and the embodiments disclosed above are equally applicable to the handheld surface cleaning devices of FIGS. 31A-31D.

[0083]

[0136] 31A-31D, motor 1322 is disposed within body 1301 and generates suction that draws dirty air into inlet 1309 (or nozzle) via dirty air passage 1330 (see FIG. 31C) during use. Dust cup 1302, and more specifically dirty air passage 1330, may be in fluid communication with motor 1322 when dust cup 1302 is in the closed position as shown in FIG. 13A. Filter 1311, disposed between body 1301 and dust cup 1302, may prevent / reduce dust and debris from entering body 1301 and ultimately clogging motor 1322. Dust and debris may then be stored within dust storage area 1331 (FIG. 31C) within the cavity of dust cup 1302 during operation of surface cleaning device 1300.

[0084]

[0137] In one embodiment, the dust cup 1302 can be disengaged from the suction of the motor 1322 when in the open position based on rotation of the dust cup 1302 relative to the body 1301. For example, as shown in FIG. 31B, an end of the dust cup 1302 can be disengaged from the body 1301 and rotated to angle the dust cup 1302 substantially transversely relative to the body 1301. As shown in FIG. 31D, the open position of the dust cup 1302 can result in the dust cup 1302 having a longitudinal axis 1316 that is substantially transverse to the longitudinal axis 1315 of the body. The angle at which the dust cup 1302 extends relative to the body 1301 can vary, for example, from 15 degrees to 180 degrees, preferably from 15 degrees to 90 degrees, depending on the desired configuration.

[0085]

[0138] In one embodiment, the body 1301 may be formed from plastic, metal, and / or any other suitable rigid material. The body 1301 may be formed from a single piece of material, or may be formed from multiple pieces.

[0086]

[0139] Body 1301 may be defined by a wall extending along longitudinal axis 1315 from a first end 1319, referred to as a dust coupling end 1319, to a second end 1320. The wall may be defined by a surface 1306, which provides a handle portion, or handle, that may be comfortably grasped in a user's hand during operation of surface cleaning device 1300.

[0087]

[0140] Body 1301 further includes a button 1305 for transitioning dust cup 1302 from, for example, a closed position as shown in Figure 31A to, for example, an open position as shown in Figure 31B. Button 1305 is not necessarily limited to a mechanical button that a user presses to transition surface cleaning device 1300 from the closed position to the open position. For example, button 1305 could also be any other suitable user input device, such as a slider button, a capacitive touch button, a rotatable ring extending around the diameter of body 1301, and the like.

[0088]

[0141] The body 1301 may define a cavity 1321 (FIG. 31C). The cavity may include a filter arrangement 1314, a motor 1322, and a power supply 1323 disposed therein. The motor 1322 may include, for example, a brushless DC motor, although other types of motors are within the scope of the present disclosure. The motor 1322 may be electrically coupled to the power supply 1323 and may generate suction to draw dirt and dust into the dust cup 1302.

[0089]

[0142] The dust cup 1302 may comprise plastic, metal, or any other suitable rigid material. The dust cup 1302 may be defined by one or more walls extending along a longitudinal axis 1316 from a first end 1309 (or nozzle) to a second end 1350 (suction coupling end or suction coupling section) ( FIG. 31D ). The dust cup 1302 further defines a cavity having a dirty air passageway 1330 extending at least partially therethrough, the dirty air passageway extending substantially parallel to the longitudinal axis 1316. The dust cup 1302 further includes a dust storage area 1331 within the cavity for receiving and storing dirt and dust. The walls surrounding the dust storage area 1331 may be optically transparent, for example, allowing 80% or more of incident visible wavelengths, allowing a user to visually inspect the current amount of dirt and dust stored in the dust storage area through the wall. The suction coupling end 1350 also provides an opening for releasing dirt and debris when the dust cup 1302 is oriented upright / vertically in the open position.

[0090]

[0143] The filter arrangement 1314 includes a generally cylindrical housing that corresponds to the shape of the body 1301. Other shapes and configurations of the filter arrangement 1314 are within the scope of this disclosure. The filter arrangement 1314 may include one or more filters, such as the pleated filter 1311 shown in FIG. 31C. The one or more filters may include, for example, a polyester material, PTFE, fiberglass, or any other suitable filter material. The one or more filters may include a cartridge body that facilitates removal and replacement of the filter.

[0091]

[0144] The filter arrangement 1314 may further include a spring 1324 for biasing the filter arrangement 1314 away from the body 1301 and toward the dust cup 1302. When the dust cup 1302 is in the closed position as shown in Figures 31A and 31C, the spring 1324 may be compressed against the dust cup 1302, displacing the filter arrangement 1314 toward the cavity 1321 of the body 1301. It should be noted that the spring 1324 may include fewer springs (e.g., a single spring) depending on the desired configuration.

[0092]

[0145] Subsequently, arms 1308-1 and 1308-2 (or arm portions) may extend from body 1301 along longitudinal axis 1315. Arms 1308-1, 1308-2 may be integrally formed with body 1301 as a single monolithic piece, or may be formed from multiple pieces. In one embodiment, arms 1308-1 and 1308-2 may be formed from the same material as body 1301, for example, plastic or other suitable rigid material. In some cases, arms 1308-1 and 1308-2 may be formed from a different material than that of body 1301. For example, arms 1308-1 and 1308-2 may be at least partially formed from a metal or metal alloy to reinforce the arms.

[0093]

[0146] Arms 1308-1 and 1308-2 may each be pivotally coupled to dust cup 1302 to permit rotational movement along a direction / path generally indicated as D ( FIG. 31B ). Thus, dust cup 1302 may pivot / rotate relative to arms 1308-1 and 1308-2 about an axis of rotation 1325, which is substantially perpendicular to longitudinal axis 1315.

[0094]

[0147] The arms 1308-1 and 1308-2 may further define a cavity. The cavity defined by the arms 1308-1 and 1308-2 may include a spring 1307. Each of the springs 1307 may bias the dust cup 1302 away from the body 1301, for example, by providing a force to the dust cup carrier 1326 or other mechanism coupled to the dust cup 1302. The dust cup carrier 1326 may be formed integrally with the dust cup 1302, i.e., as a single monolithic piece, or may be formed from multiple components. The dust cup carrier 1326 is configured to move longitudinally along tracks / guides provided by the arms 1308-1 and 1308-2. Thus, the dust cup carrier 1326 may be used to transition / displace the dust cup 1302 from a closed position to an open position.

[0095]

[0148] Detents 1399 ( FIG. 31B ) or other suitable locking mechanisms may extend from the surfaces of the arms 1308-1 and 1308-2 to securely hold the dust cup carrier 1326, and thus the dust cup 1302, in the closed position. The detents 1399 may be spring-loaded and configured to engage corresponding surface features on the dust cup 1302, such as catches / recesses 1327. Thus, when the dust cup 1302 is pressed into alignment with the filter arrangement 1314, based on, for example, a user-supplied force, the detents 1399 can engage the catches 1327 on the dust cup 1302 to securely hold the dust cup 1302 in place relative to the body 1301.

[0096]

[0149] To release the dust cup 1302 and transition it to the open position, a user may press a button 1305. Pressing the button 1305 may involve using a pinching motion with the thumb and index finger against a button located on opposite sides of the body 1301. In response, the button 1305 may mechanically actuate a detent 1399, disengaging it from a catch on the dust cup 1302. Alternatively, the button 1305 may provide an electrical signal that is used, for example, by a motor or other mechanical actuator to release the detent 1399.

[0097]

[0150] In either case, button 1305 may therefore transition dust cup 1302 to an open position, allowing a user to empty the dust cup and clean the dust and debris filter. Dust cup 1302 may include a recessed surface 1339 (see FIG. 31B ) or recessed area 1339 that defines a sidewall 1341. Sidewall 1341 extends substantially perpendicular to surface 1339. Sidewall 1341 may be configured to engage stop surfaces 1340 on arms 1308-1 and 1308-2 to prevent rotational movement of dust cup 1302 beyond a predetermined limit (e.g., 90 degrees). Impact of dust cup 1302 encountering stop surfaces 1340 may advantageously release dirt and debris within dust cup 1302.

[0098]

[0151] 31D , the filter arrangement 1314 may include a protrusion / catch / surface 1344 for engaging a corresponding stop / protrusion 1398 on the body 1301. The dust cup 1302 may include a recessed area / guide 1340 for engaging the protrusion 1398. Thus, the protrusion 1398 may be used to align and guide the dust cup 1302 with the body 1301 as the dust cup 1302 transitions back to the closed position.

[0099]

[0152] In one embodiment, the surface cleaning apparatus 1300 can be held in one hand and transitioned from the closed position to the open position by that hand.

[0100]

[0153] 32A-32D collectively illustrate the handheld surface cleaning device 1300 transitioning from a closed position to an open position. In particular, FIG. 32A illustrates the handheld surface cleaning device 1300 in the closed position, whereby the dust cup 1302 is in fluid communication with a motor disposed within the body 1301, according to an embodiment of the present disclosure.

[0101]

[0154] Figure 32B shows the handheld surface cleaning device 1300 after a user presses one or both of the buttons 1305 on either side of the body 1301, according to one embodiment of the present disclosure. In response to the press button 1305 being pressed, the detent 1399 (Figure 31B) may disengage from the dust cup 1302. Similarly, and as shown in Figure 32C, the dust cup 1302 and filter arrangement 1314 may move longitudinally away from the body 1301. In some cases, there may be a momentary pause between the rotational movement of the dust cup 1302 and the movement of the filter arrangement 1314, depending on the desired configuration.

[0102]

[0155] 32D, the dust cup 1302 may rotate / pivot relative to the body 1301 and may stop in a position that holds the dust cup 1302 in a substantially transverse orientation relative to the body 1301. The dust cup 1302 may pivot based on tracks / guides provided by the arms 1308-1 and 1308-2. Alternatively, or additionally, weight may be added to the dust cup 1302 to naturally tend it toward a vertical / upright orientation.

[0103]

[0156] The dust cup 1302 may be held in this position based at least in part on springs 1307 disposed on the first and second arms 1308-1 and 1308-2 (see FIG. 31B ). Similarly, the filter arrangement 1314 may be held in the extended position based on a spring bias from spring 1324. Accordingly, the user may then shake the handheld surface cleaning device 1300 to empty the dust and debris from the dust cup 1302. To place the dust cup 1302 in the closed position for further use, the user simply rotates the dust cup 1302 into alignment with the main body 1301 and then slides the dust cup 1302 toward the main body 1301, moving the filter arrangement 1314 and "locking" it into the closed position based on detents 1399 engaging sidewall features of the dust cup 1302, such as recesses 1327.

[0104]

[0157] FIG. 33 illustrates an additional exemplary embodiment of a surface cleaning apparatus consistent with embodiments of the present disclosure.

[0105]

[0158] Figures 34A-34C illustrate additional exemplary embodiments of a surface cleaning apparatus consistent with embodiments of the present disclosure. It should be noted that the exemplary aspects illustrated in Figures 34A-34C are equally applicable to the embodiment illustrated in Figure 8.

[0106]

[0159] 35-35B illustrate additional exemplary embodiments of a surface cleaning device consistent with embodiments of the present disclosure.

[0107]

[0160] 36A-36B illustrate additional exemplary embodiments of a surface cleaning device consistent with embodiments of the present disclosure.

[0108]

[0161] 37-45 show an additional exemplary embodiment of a handheld surface cleaning device 1900 having a body 1901 including a handle 1907, an expandable crevice tool 1902, a cyclone assembly 1904, and a motor 1912 electrically coupled to at least one battery 1905. The battery 1905 may be stored within the handle 1907. As shown, the cyclone assembly 1904 includes an inlet 1906 fluidly coupled with the crevice tool 1902, a vortex finder 1908, a collection area 1910, and a filter 1914. During operation, air is drawn into the cyclone assembly 1904 from the crevice tool inlet 1916. The air may include, for example, dust collected during a cleaning operation. Dust carried in the air may be collected within the cyclone assembly 1904 (e.g., in the collection area 1910).

[0109]

[0162] When a sufficient amount of dust has collected within the cyclone assembly 1904, an operator may empty the dust by opening a door 1918. When the door 1918 is opened, the dust may exit the cyclone assembly 1904 (e.g., by gravity). An operator can open the door 1918 by actuating a button (or trigger) 1920. In some instances, actuation of the button 1920 may result in movement of a push rod 1922. As the push rod 1922 moves between the first and second positions, the push rod 1922 may engage a latch 1924 that holds the door 1918 in a closed position. As shown, as the latch 1924 moves out of engagement with the door 1918, the door 1918 rotates about an axis 1926.

[0110]

[0163] Once released, the operator can re-close the door 1918 by returning the door 1918 to engagement with the latch 1924. Additionally or alternatively, the user can actuate the button 1920 (or actuate or trigger a different button) to a second position to close the door 1918. In some instances, the latch 1924 can include a biasing member (e.g., a spring) that biases the latch 1924 toward an engaged position (e.g., a position where the latch 1924 can engage the door 1918).

[0111]

[0164] The gap tool 1902 may be extendable from a first position to a second position. For example, an operator may manually grasp the gap tool 1902 and pull (or push) the gap tool 1902 to transition the gap tool 1902 between the first and second positions. Additionally or alternatively, the gap tool 1902 may transition between the first and second positions in response to actuation of a button (or trigger).

[0112]

[0165] Also, as shown, at least a portion of cyclone assembly 1904 may be removably coupled to body 1901 of handheld surface cleaning device 1900. For example, removal of cyclone assembly 1904 may allow a user to clean and / or replace filter 1914. By way of further example, in some examples, vortex finder 1908 may be removable. As shown, a tip at feature 1917 may be provided for coupling cyclone assembly 1904 to body 1901.

[0113]

[0166] In some instances, the handheld surface cleaning device 1900 may be used in a robotic vacuum cleaner system. For example, the handheld surface cleaning device 1900 may be used to remove dust from a robotic vacuum cleaner.

[0114]

[0167] According to one aspect, a handheld surface cleaning device is disclosed that includes a body extending from a first end to a second end, a handle portion defined by the body adjacent the first end, a nozzle having a dirty air inlet defined by the body adjacent the second end, a motor for generating suction to draw air into the dirty air inlet, and a dust cup for receiving and storing dust and debris, the dust cup rotatably coupled to the body of the handheld surface cleaning device and configured to transition between a closed orientation that fluidly couples the dust cup to the dirty air inlet and the motor and a release orientation that decouples the dust cup from the dirty air inlet and the motor to allow dust and debris stored in the dust cup to exit an opening in the dust cup.

[0115]

[0168] According to another aspect, a docking system is disclosed. a dock including a robotic vacuum coupling section; a handheld surface cleaning device including a body extending from a first end to a second end, a handle portion defined by the body adjacent the first end, a nozzle having a dirty air inlet defined by the body adjacent the second end, a motor for generating suction and drawing air into the dirty air inlet, and a dust cup for receiving and storing dirt and dust, the dust cup rotatably coupled to the body of the handheld surface cleaning device and configured to transition between a closed orientation that fluidly couples the dust cup to the dirty air inlet and the motor and a release orientation that decouples the dust cup from the dirty air inlet and the motor to allow dirt and dust stored in the dust cup to exit an opening in the dust cup; and a receptacle defined by the dock that receives and couples the first end of the handheld surface cleaning device and extends the second end, defining the handle portion, away from the dock.
