Cleaning robots and cleaning systems

[0001] Cross-reference of related applications

[0002] This application claims priority to Chinese patent application No. 202422627311.2, filed on October 29, 2024, entitled "Cleaning Robot and Cleaning System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of cleaning equipment technology, and more particularly to a cleaning robot and cleaning system. Background Technology

[0004] As people's living standards improve, cleaning robots are gradually entering the daily lives of more and more people. Cleaning robots are equipped with a mop and two drive wheels at their bottom. They move using the two drive wheels and use the mop to clean the floor as they move.

[0005] Currently, some cleaning robots have added edge mops to the edges. However, the edge mops may take up space of the original components located on the edges of the body, making the body structure more compact. This may require sacrificing the length of the main mop, which means that the main mop cannot completely cover the walking path of the two drive wheels. As a result, traces or stains generated by the drive wheels when they walk are easily left on the ground, causing secondary pollution and a poor user experience.

[0006] Public content

[0007] To address the aforementioned technical problems, this disclosure provides a cleaning robot and cleaning system that can cover the walking trajectory of the two drive wheels, thereby ensuring cleaning effectiveness.

[0008] In a first aspect, this disclosure provides a cleaning robot, including a body, with a walking component and a mopping component disposed at the bottom of the body. In the front-rear direction of the body, the walking component is located in front of the mopping component. The walking component includes a first drive wheel and a second drive wheel symmetrically arranged in the width direction of the body. The second drive wheel is close to the edge side of the body. The mopping component includes a main mopping component and an edge mopping component disposed in the edge side of the body. The main mopping component is offset in the width direction of the body, and the projection of the end of the main mopping component away from the edge side of the body on the ground at least covers the walking trajectory of the first drive wheel. The projection of the edge mopping component on the ground at least covers part of the walking trajectory of the second drive wheel. The end of the main mopping component away from the first drive wheel extends towards the second drive wheel to dock with the edge mopping component in the width direction of the body.

[0009] In some embodiments, the projection of the main wiping member on the ground at least covers a portion of the travel path of the second drive wheel.

[0010] In some embodiments, the projection of the edge-dragging member onto the ground covers the travel path of the second drive wheel.

[0011] In some embodiments, the mopping assembly includes an edge cleaning bracket that supports the edge mopping member, the edge cleaning bracket being slidably disposed on the body, and the edge mopping member having an extended position and a retracted position within a sliding range;

[0012] When the edge-dragging component is in the extended position, the end of the edge-dragging component near the first drive wheel is connected to the main dragging component.

[0013] In some embodiments, in the longitudinal direction of the body, the edge-dragging member is located between the walking assembly and the main dragging member.

[0014] In some embodiments, a drive assembly disposed along the edge of the body is further included, the drive assembly being configured to drive the main mopping component to rotate in order to clean the floor.

[0015] In some embodiments, the mopping assembly includes a mopping bracket and a transmission structure disposed on the mopping bracket, the main mopping component is supported on the transmission structure, the transmission structure and the drive assembly are detachably connected, and the drive assembly drives the main mopping component to rotate through the transmission structure.

[0016] In some embodiments, the body has a receiving notch on its edge side that opens toward the outer periphery of the body, and the receiving notch extends through the upper and lower sides of the body, and the edge-draping member is disposed within the receiving notch.

[0017] In some embodiments, the top of the body is further provided with a cover, which at least partially covers the top of the receiving notch.

[0018] In a second aspect, this disclosure provides a cleaning system, including a cleaning base station; and a cleaning robot provided in the first aspect, wherein the cleaning base station has a base station cavity for the cleaning robot to enter, and the side wall of the base station cavity is provided with a clearance notch for avoiding the edge-dragging component.

[0019] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0020] 1. This cleaning robot features an edge-mopping component along the edge of its body, while the main mopping component is offset along the width of the body. This frees up installation space for other components located along the edge, such as the drive motor of the main mopping component. Furthermore, the projection of the end of the main mopping component away from the edge onto the ground at least covers the trajectory of the first drive wheel, and the projection of the edge-mopping component at least covers part of the trajectory of the second drive wheel. The end of the main mopping component away from the first drive wheel extends towards the second drive wheel to mate with the edge-mopping component along the width of the body. This arrangement of the main and edge-mopping components effectively covers the trajectories of both the first and second drive wheels, completely clearing their paths. The seamless connection between the main and edge-mopping components along the width of the body increases the cleaning width, prevents uncleaned areas, ensures cleaning effectiveness and efficiency, and improves the user experience.

[0021] 2. By offsetting the main dragging component, it can cooperate with the edge dragging component set on the edge side of the machine body to balance the center of gravity of the machine body in its own width direction, improve the balance of the machine body in its own width direction, and thus improve the stability of the machine body when moving.

[0022] 3. By setting the edge mopping component to slide horizontally relative to the body, the edge mopping component has an extended position and a retracted position within the sliding range. Moreover, when in the extended position, the edge mopping component can still cover the walking trajectory of the second drive wheel, and it docks with the main mopping component in the width direction of the body so that there is no gap between the two, which can increase the cleaning width and avoid leaving uncleaned areas, thus ensuring cleaning effect and cleaning efficiency.

Detailed Implementation

[0032] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] Numerous specific details are set forth in the following description to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein. Clearly, the embodiments described in the specification are only a part of, and not all, of the embodiments of this disclosure.

[0034] As shown in Figure 1, this embodiment of the present disclosure provides a cleaning robot 10, which includes a body 1. A walking component 2 and a mopping component 3 are provided at the bottom of the body 1. In the front-rear direction of the body 1, the walking component 2 is located in front of the mopping component 3. The walking component 2 includes a first drive wheel 21 and a second drive wheel 22 symmetrically arranged in the width direction of the body 1. The second drive wheel 22 is close to the edge side of the body 1. The mopping component 3 includes a main mopping component 31 and an edge mopping component 32 provided on the edge side of the body 1.

[0035] The main wiping component 31 is offset in the width direction of the body 1, and the projection of the end of the main wiping component 31 away from the edge of the body 1 onto the ground at least covers the walking trajectory of the first drive wheel 21. The projection of the edge wiping component 32 onto the ground at least covers part of the walking trajectory of the second drive wheel 22, and the end of the main wiping component 31 away from the first drive wheel 21 extends towards the second drive wheel 22 to connect with the edge wiping component 32 in the width direction of the body 1. The front-back direction of the body 1 is shown in the X direction of Figure 1, the width direction of the body 1 is shown in the Y direction of Figure 1, and the edge of the body 1 is one side in the width direction of the body 1.

[0036] It should be noted that, firstly, the offset of the main wiping component 31 in the width direction of the body 1 means that the main wiping component 31 is not symmetrically arranged in the width direction of the body 1, but is arranged on one side relatively close to the width direction of the body 1, such as near the edge side of the body 1. This frees up installation space for components also located on the edge side of the body 1, such as the drive motor that drives the main wiping component 31. Moreover, the offset arrangement of the main wiping component 31 can cooperate with the edge wiping component 32 arranged on the edge side of the body 1 to balance the center of gravity of the body 1 in its own width direction, improve the balance of the body 1 in its width direction, improve the stability of the body 1 when moving, and prevent the body 1 from tilting in the width direction when moving.

[0037] Specifically, the main wiping component 31 is divided into two parts in the width direction of the body 1 by the center surface of the body 1 extending in the front-back direction. One part is wider in the width direction of the body 1 than the other part, as shown in Figure 1, where A2 is greater than A1.

[0038] Secondly, the fact that the end of the main wiping member 31 away from the first drive wheel 21 extends toward the second drive wheel 22 to mate with the edge wiping member 32 means that the main wiping member 31 and the edge wiping member 32 are aligned or overlap each other.

[0039] This can be understood as follows: there is no gap between the main wiping component 31 and the edge wiping component 32 in the width direction of the body 1. In this case, in the width direction of the body 1, the edge of the main wiping component 31 away from the first drive wheel 21 is flush with the edge of the edge wiping component 32 closer to the first drive wheel 21, or the edge wiping component 32 partially overlaps with the main wiping component 31 in the front-rear direction of the body 1. For example, the projection of the main wiping component 31 on the ground can cover part of the travel trajectory of the second drive wheel 22, and the projection of the edge wiping component 32 on the ground can cover another part of the travel trajectory of the second drive wheel 22, with both covering the entire travel trajectory of the second drive wheel 22.

[0040] Alternatively, the projection of the main wiping component 31 on the ground may not cover the travel trajectory of the second drive wheel 22, while the projection of the side wiping component 32 on the ground may cover the entire travel trajectory of the second drive wheel 22.

[0041] Alternatively, the projection of the main wiping member 31 on the ground may cover the travel trajectory of the second drive wheel 22, or the projection of the edge wiping member 32 on the ground may cover the travel trajectory of the second drive wheel 22. Furthermore, when the projection of the edge wiping member 32 on the ground covers the travel trajectory of the second drive wheel 22, the projections of the main wiping member 31 and the edge wiping member 32 on the ground overlap, meaning that the projection of the main wiping member 31 on the ground covers the projection of the edge wiping member 32 on the ground.

[0042] Furthermore, the aforementioned walking assembly 2 also includes a driven wheel 23, which is located in front of the first drive wheel 21 and the second drive wheel 22 in the longitudinal direction of the body 1, and the driven wheel 23 is located between the first drive wheel 21 and the second drive wheel 22 in the width direction of the body 1. This arrangement improves the stability of the body 1 during movement, while controlling the relative speed difference between the first drive wheel 21 and the second drive wheel 22 to achieve steering of the body 1.

[0043] Among them, the driven wheel 23 can be selected as a universal wheel, which makes it easy to turn the body 1 when it moves.

[0044] In summary, this cleaning robot has an edge-dragging component 32 on the edge side of the body 1, while the main dragging component 31 is offset in the width direction of the body 1, which can free up space for components also located on the edge side, such as the drive motor of the main dragging component 31.

[0045] Meanwhile, the projection of the end of the main mopping component 31 away from the body 1 along the edge onto the ground at least covers the walking trajectory of the first drive wheel 21, and the projection of the edge mopping component 32 onto the ground at least covers part of the walking trajectory of the second drive wheel 22. The end of the main mopping component 31 away from the first drive wheel 21 extends towards the second drive wheel 22 to connect with the edge mopping component 32 in the width direction of the body 1. The arrangement of the main mopping component 31 and the edge mopping component 32 can cover the walking trajectories of the first drive wheel 21 and the second drive wheel 22, completely clearing their paths. Furthermore, the main mopping component 31 and the edge mopping component 32 connect in the width direction of the body 1 without gaps, increasing the cleaning width and preventing uncleaned areas, ensuring cleaning effect and efficiency, and improving user experience.

[0046] Furthermore, by offsetting the main dragging member 31, it can cooperate with the edge dragging member 32 provided on the edge side of the body 1 to balance the center of gravity of the body 1 in its own width direction, improve the balance of the body 1 in its own width direction, and thus improve the stability of the body 1 when it moves.

[0047] In some embodiments, referring to FIG1, the cleaning robot 10 further includes a drive assembly 4 disposed on the side of the body 1, the drive assembly 4 being configured to drive the main mopping member 31 to rotate to clean the floor.

[0048] Understandably, the offset of the main mopping component 31 not only cooperates with the edge mopping component 32 to cover the travel paths of the first drive wheel 21 and the second drive wheel 22, but also frees up space for the installation of the drive assembly 4. The mopping assembly 3 includes a mopping bracket and a transmission structure mounted on the mopping bracket. The main mopping component 31 is supported on the transmission structure, and the transmission structure and the drive assembly 4 are detachably connected. The drive assembly 4 drives the main mopping component 31 to rotate through the transmission structure.

[0049] For example, the main mopping component 31 can be selected as a tracked mop. The aforementioned transmission structure includes a first rotating shaft and a second rotating shaft disposed on the mopping bracket. The tracked mop is wound around the first rotating shaft and the second rotating shaft. One of the first rotating shaft and the second rotating shaft is a drive shaft, which can be detachably connected to the drive assembly, and the other is a driven shaft. The drive assembly 4 can be selected as a motor. The output shaft of the motor is detachably connected to the drive shaft, which facilitates the installation and removal of the mopping component 3.

[0050] Of course, the main mopping component 31 mentioned above can also be a roller mop. In this case, the roller mop is rotatably mounted on the mopping bracket, and the roller of the roller mop can be detachably connected to the drive component. For example, if the drive component is a motor, the roller extends outward with a connecting shaft, which can be detachably connected to the output shaft of the motor.

[0051] In some embodiments, referring to FIG1, in the front-rear direction of the body 1, the edge-dragging member 32 is located between the walking assembly 2 and the main dragging member 31.

[0052] Understandably, when the machine body 1 moves, the edge mopping component 32 is located in front of the main mopping component 31. Thus, when the edge mopping component 32 cleans the corner area, the main mopping component 31 can clean the residual dirt on the end of the edge mopping component 32 that is relatively close to the first drive wheel 21 in the width direction of the machine body 1, improving the cleaning effect and preventing cleaning marks from remaining under the machine body when there is excessive dirt in the corner area. Especially when the edge mopping component 32 and the main mopping component 31 overlap in the front-rear direction of the machine body 1, the main mopping component 31 can further clean the area cleaned by the edge mopping component 32, improving the cleaning effect.

[0053] In this case, the projection of the main mopping component 31 on the ground at the end away from the edge of the body 1 covers part of the walking trajectory of the second drive wheel 22, and the projection of the edge mopping component 32 on the ground covers at least part of the walking trajectory of the second drive wheel 22. Furthermore, the edge mopping component 32 partially overlaps with the main mopping component 31 in the front-rear direction of the body 1. That is, in the width direction of the body 1, the end of the edge mopping component 32 that is relatively closer to the first drive wheel 21 is located inside the end of the main mopping component 31 that is away from the first drive wheel 21. In this way, the main mopping component 31 can clean the area cleaned by the edge mopping component 32 again, which is beneficial to improving the cleaning effect.

[0054] In some embodiments, the projection of the main wiping member 31 on the ground at least covers a portion of the walking trajectory of the second drive wheel 22.

[0055] Understandably, the projection of the main wiping member 31 on the ground can cover part of the travel trajectory of the second drive wheel 22. At this time, the projection of the side wiping member 32 on the ground covers at least part of the travel trajectory of the second drive wheel 22 that is not covered by the main wiping member 31. That is, at this time, the side wiping member 32 covers another part of the travel trajectory of the second drive wheel 22, or the projection of the side wiping member 32 on the ground covers part or the entire travel trajectory of the second drive wheel 22. When the projection of the side wiping member 32 on the ground covers part of the travel trajectory of the second drive wheel 22, the projections of the main wiping member 31 and the side wiping member 32 on the ground cover the travel trajectory of the second drive wheel 22 with an overlapping part. In other words, the projection of the main wiping member 31 on the ground covers part of the projection of the side wiping member 32 on the ground.

[0056] Furthermore, in the width direction of the body 1, the edge of the main wiping member 31 away from the edge wiping member 32 is flush with the outer edge of the first drive wheel 21.

[0057] The end of the main mopping component 31 furthest from the edge mopping component 32 just covers the first drive wheel 21, which helps to reduce the overall width of the body 1 and achieve a miniaturized design. Of course, the end of the main mopping component 31 furthest from the edge mopping component 32 can also extend beyond the outer edge of the first drive wheel 21, thus increasing the cleaning range of the main mopping component 31 in the width direction of the body 1.

[0058] Furthermore, in the front-rear direction of the body 1, the edge-dragging component 32 is located between the walking component 2 and the main dragging component 31.

[0059] Understandably, when the machine body 1 moves, the edge mopping component 32 is located in front of the main mopping component 31. Thus, when the edge mopping component 32 cleans the corner area, the main mopping component 31 can clean the residual dirt on the end of the edge mopping component 32 that is relatively close to the first drive wheel 21 in the width direction of the machine body 1, improving the cleaning effect and preventing cleaning marks from remaining under the machine body when there is excessive dirt in the corner area. Especially when the edge mopping component 32 and the main mopping component 31 overlap in the front-rear direction of the machine body 1, the main mopping component 31 can further clean the area cleaned by the edge mopping component 32, improving the cleaning effect.

[0060] In some embodiments, the projection of the edge-dragging member 32 on the ground covers the walking trajectory of the second drive wheel 22.

[0061] Understandably, the edge-dragging member 32 can cover the travel trajectory of the second drive wheel 22 on its own. At this time, the main dragging member 31 may not cover the travel trajectory of the second drive wheel 22 or may cover part of the travel trajectory of the second drive wheel 22.

[0062] When the main mopping component 31 covers part of the travel path of the second drive wheel 22, the edge mopping component 32 and the main mopping component 31 cover part of the travel path of the second drive wheel 22, which means that the edge mopping component 32 and the main mopping component 31 overlap in the front-rear direction of the body 1. This ensures that the edge mopping component 32 and the main mopping component 31 completely cover the second drive wheel 22, which is beneficial to improving the cleaning effect.

[0063] For example, in one specific implementation, referring to FIG2, in the width direction of the body 1, the distance between the outer edge of the first drive wheel 21 and the outer edge of the second drive wheel 22 is C, the length of the main dragging member 31 is A, the length of the edge dragging member 32 is B, and the length of the portion of the edge dragging member 32 and the main dragging member 31 overlapping in the front-rear direction of the body is D, wherein A+BD>C.

[0064] It should be noted that in other implementations, when the edge of the main wiping member 31 away from the first drive wheel 21 is flush with the edge of the edge wiping member 32 closer to the first drive wheel 21 in the width direction of the body 1, D is 0, and A+B>C. Alternatively, A+BD can also be equal to C, in which case the edge of the main wiping member 31 away from the edge wiping member 32 is flush with the outer edge of the first drive wheel 21, while the edge of the edge wiping member 32 away from the first drive wheel 21 is flush with the outer edge of the second drive wheel 22, and the edge of the main wiping member 31 away from the first drive wheel 21 extends towards the second drive wheel 22 to mate with the edge wiping member 32.

[0065] Furthermore, in the front-rear direction of the body 1, the edge-dragging component 32 is located between the walking component 2 and the main dragging component 31.

[0066] Understandably, when the machine body 1 moves, the edge mopping component 32 is located in front of the main mopping component 31. Thus, when the edge mopping component 32 cleans the corner area, the main mopping component 31 can clean the residual dirt on the end of the edge mopping component 32 that is relatively close to the first drive wheel 21 in the width direction of the machine body 1, improving the cleaning effect and preventing cleaning marks from remaining under the machine body 1 when there is excessive dirt in the corner area. Especially when the edge mopping component 32 and the main mopping component 31 overlap in the front-rear direction of the machine body 1, the main mopping component 31 can further clean the area cleaned by the edge mopping component 32, improving the cleaning effect.

[0067] In some embodiments, the mopping assembly 3 includes an edge cleaning bracket 33 supporting the edge mopping member 32. The edge cleaning bracket 33 is slidably disposed on the body 1. The edge mopping member 32 has an extended position and a retracted position within its sliding range. When the edge mopping member 32 is in the extended position, the end of the edge mopping member 32 near the first drive wheel 21 is connected to the main mopping member 31. When the edge mopping member 32 moves from the retracted position to the extended position, the edge mopping member 32 moves outward from the body 1; when it moves from the extended position to the retracted position, the edge mopping member 32 moves inward from the body 1.

[0068] It should be noted that the alignment of the edge-dragging component 32 near the first drive wheel 21 with the main dragging component 31 means that the main dragging component 31 and the edge-dragging component 32 are aligned or overlap each other. This can be understood as the main dragging component 31 and the edge-dragging component 32 having no gap in the width direction of the body 1. In this case, in the width direction of the body 1, the edge of the edge-dragging component 32 near the first drive wheel 21 is flush with the edge of the main dragging component 31 away from the first drive wheel 21, or the edge of the edge-dragging component 32 near the first drive wheel 21 is located inside the edge of the main dragging component 31 away from the first drive wheel 21. In this case, part of the edge-dragging component 32 overlaps with the main dragging component 231 in the front-rear direction of the body 1.

[0069] Understandably, when the edge-dragging component 32 is in the extended position, the end of the edge-dragging component 32 near the first drive wheel 21 is connected to the main dragging component 31, which indicates that there is no gap between the edge-dragging component 32 and the main dragging component 31 in the width direction of the body 1. Then, when the edge-dragging component 32 is in the retracted position, part of the edge-dragging component 32 overlaps with the main dragging component 31 in the front-back direction of the body 1.

[0070] By configuring the edge-dragging component 32 to slide horizontally relative to the body 1, it can slide to the extended position when edge cleaning is needed, and to the retracted position when edge cleaning is not needed. This reduces the size of the cleaning robot in its width direction, making it easier for the cleaning robot to enter the base station. Furthermore, even in the extended position, the edge-dragging component 32 can still cover the walking trajectory of the second drive wheel 22, and its connection with the main dragging component 31 in the width direction of the body 1 ensures there are no gaps between them, increasing the cleaning width and preventing uncleaned areas, thus guaranteeing cleaning effect and efficiency.

[0071] For example, the aforementioned edge cleaning bracket 33 can be driven to translate by a drive structure, such as a motor, gear, and rack. The rack is mounted on the edge cleaning bracket 33, the motor is mounted on the body 1, the gear is connected to the output shaft of the motor, and the gear meshes with the rack. The motor can drive the gear to rotate to drive the rack to move in the extension direction of the rack, thus realizing the sliding of the edge cleaning bracket 33, thereby enabling the edge mopping member 32 to switch between the extended position and the retracted position.

[0072] In some embodiments, referring to Figures 3 and 4, the body 1 is provided with a receiving notch 11 on its edge side that opens toward the outer periphery of the body 1, and the receiving notch 11 extends through the upper and lower sides of the body 1, and the edge dragging member 32 is disposed in the receiving notch 11.

[0073] Understandably, by providing the receiving notch 11 to accommodate the edge mopping component 32, thus providing space for its installation, the overall thickness of the cleaning robot 10 can be reduced. Furthermore, when the edge mopping component 32 uses a tracked mop, the tracked mop can be exposed through the receiving notch 11, making it easy to observe the cleanliness of the tracked mop and thus allowing the user to determine whether the edge mopping component 32 needs cleaning.

[0074] For example, in one specific implementation, the aforementioned edge mopping component 32 can be slidably disposed within the receiving notch 11. For instance, the edge mopping component 32 can be supported by the edge cleaning bracket 33, which can slide horizontally relative to the body 1, allowing the edge mopping component 32 to slide outward or inward towards the body 1. The position of the edge mopping component 32 can be adjusted according to actual needs.

[0075] It should be noted that when the edge mopping component 32 slides outward from the body 1, the end of the edge mopping component 32 near the first drive wheel 21 must always be aligned with the main mopping component 31 in the width direction of the body 1 to avoid gaps between the two in the width direction of the body 1 and to ensure cleaning effect.

[0076] The edge cleaning bracket 33 can be driven to move by a drive structure. The drive structure can be set in the receiving notch 11. For example, the drive structure can be a motor, a gear and a rack. The rack is set on the edge cleaning bracket 33, the motor is set on the body 1, the gear is connected to the output shaft of the motor, and the gear meshes with the rack. The motor can drive the gear to rotate to drive the rack to move in the extension direction of the rack. This can realize the sliding of the edge cleaning bracket 33, thereby enabling the edge mopping component 32 to switch between the extended position and the retracted position.

[0077] In one specific implementation, referring to Figures 3 to 5, a horizontally extending pivot 12 is provided within the accommodating notch 11. The edge-mopping member 32 is supported on the edge-cleaning bracket 33. The edge-cleaning bracket 33 can rotate up and down around the pivot 12, allowing the edge-mopping member 32 to have a cleaning position (as shown in Figure 4) and a mopping position (as shown in Figure 3). When the edge-mopping member 32 is in the mopping position, it is in contact with the ground, and at least partially located on the outer edge of the body 1. When the edge-mopping member 32 is in the cleaning position, it is detached from the ground, allowing for cleaning of the edge-mopping member 32 without flipping the entire body 1.

[0078] For example, referring to Figures 3 and 4, the edge cleaning bracket 33 rotates 90° from the edge mopping member 32 from the mopping position to the cleaning position, and similarly, the edge mopping member 32 rotates 90° from the cleaning position to the mopping position. When the edge mopping member 32 is in the cleaning position, it is exposed from the upper side of the body 1 for easy cleaning.

[0079] Furthermore, the edge mopping component 32 is detachably mounted on the edge cleaning bracket 33. When the edge mopping component 32 is in the cleaning position, it is located outside the receiving notch 11, so that the edge mopping component 32 can be detached from the edge cleaning bracket 33.

[0080] Understandably, the edge mop 32 is detachably mounted on the edge cleaning bracket 33, facilitating its installation and removal. Furthermore, when the edge mop 32 is in the cleaning position, it is located outside the receiving notch 11. This not only allows for cleaning of the edge mop 32 when it is in the cleaning position but also enables its replacement, further enhancing the user experience.

[0081] It should be noted that when the edge mopping component 32 is in the mopping position, the end of the edge mopping component 32 near the first drive wheel 21 is connected to the main mopping component 31 to avoid gaps between the two in the width direction of the body 1 and to ensure the cleaning effect.

[0082] For example, in another specific implementation, the top of the body 1 is further provided with a cover, which at least partially covers the top of the receiving notch 11.

[0083] Understandably, by providing a cover, the receiving notch 11 can be covered, allowing the edge mopping component 32 to be hidden under the cover, improving aesthetics, and protecting the edge mopping component 32 from dust accumulation.

[0084] This disclosure also provides a cleaning system 100. Referring to FIG6, the cleaning system 100 includes a cleaning base station 20 and a cleaning robot 10 in any of the above embodiments. The cleaning base station 20 has a base station cavity 20a for the cleaning robot 10 to enter. The side wall of the base station cavity 20a is provided with a clearance notch 20b that can avoid the edge dragging member 32.

[0085] Understandably, after a period of use, the main wiping component 31 of the cleaning robot 10 needs to enter the base station cavity 20a of the cleaning base station 20 for cleaning. Since at least part of the edge wiping component 32 is located outside the edge of the body 1, the cleaning robot 10 needs to avoid the edge wiping component 32 when entering the base station cavity 20a.

[0086] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0087] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to these embodiments, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
