[0035] The current cleaning device usually collects and sweeps the debris and hair around the cleaning device through the rotating side brush, and then absorbs the dust through the dust suction port of the cleaning device. However, when the cleaning device is used to clean the surface to be cleaned, there may be not only solid waste objects, dust and the like on the surface to be cleaned, but also liquid sewage, accumulated liquid and the like that need to be cleaned by a cloth or mop. The rotating side brush will increase the area of the sewage or even splash, resulting in further increase in cleaning difficulty. To solve the above technical problems, the embodiments of the present application are proposed as follows.

[0036] The following embodiments of the surface cleaning device of the present application describe an exemplary structure of the cleaning device.

[0037] Please refer to Figures 1-4 , Figure 1is a structural schematic view of the edge brush mechanism provided by the embodiments of the present application, Figure 2 is Figure 1 is a cross-sectional structural schematic view of the edge brush mechanism, Figure 3 is Figure 1 is an exploded schematic view of the edge brush mechanism, Figure 4 is Figure 1 is a structural schematic view of the bottom cover of the edge brush mechanism.

[0038] Referring to Figures 1-4 , the embodiments of the present application provide an edge brush mechanism 1000. The edge brush mechanism 1000 comprises an edge brush assembly 100, a driving assembly 200, a lifting assembly 300 and a bottom cover 400. The edge brush assembly 100 comprises at least one edge brush 110. The driving assembly 200 is drivingly connected to the edge brush assembly 100 to drive the edge brush assembly 100 to rotate. The lifting assembly 300 is linked with the edge brush assembly 100 and the driving assembly 200. The bottom cover 400 is arranged at the end of an output shaft 230 of the driving assembly 200. The bottom cover 400 is provided with a flange 410 at the periphery thereof, the flange 410 has a notch 411, and the side wall of the notch 411 comprises an inclined surface 4111 inclined with respect to the driving assembly 200, and the edge brush assembly 100 is slidingly fitted on the inclined surface 4111. The driving assembly 200 and the lifting assembly 300 are used to control the edge brush 110 to move along the inclined surface 4111 towards or away from the driving assembly 200 or to rotate with the driving assembly 200.

[0039] In some embodiments, the edge brush 110 comprises an edge brush body and an edge brush cleaning part, and the edge brush cleaning part is arranged to be spaced apart from the driving assembly 200 by the edge brush body. In some embodiments, the edge brush body and the edge brush cleaning part are detachably connected, so as to facilitate replacement of one or both of the edge brush body and the edge brush cleaning part, and improve the utilization rate of parts. In some embodiments, the edge brush cleaning part is made of a flexible material, such as rubber and / or silica gel, so as to improve the protection of the surface to be cleaned when cleaning the surface to be cleaned.

[0040] In some embodiments, referring to Figure 4, the first end 4111a and the second end 4111b of the inclined surface 4111 are spaced apart along the direction in which the brush assembly 100 rotates, and the distance between the first end 4111a and the driving assembly 200 is greater than the distance between the second end 4111b and the driving assembly 200. The driving assembly 200 drives the brush assembly 100 to rotate in the first direction d1, and the brush 110 rotates in the first direction d1 relative to the bottom cover 400 under the action of the lifting assembly 300. The brush 110 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b, that is, the brush 110 is displaced in the axial direction of the rotation of the brush assembly 100, that is, the brush 110 is lifted relative to the surface to be cleaned and moves away from the surface to be cleaned, so as to reduce the possibility that the brush 110 rotates to increase the area of the liquid or even splash the liquid, and improve the adaptability of the brush mechanism 1000 to different cleaning environments. The driving assembly 200 drives the brush assembly 100 to rotate in the second direction d2, and the brush 110 rotates in the second direction d2 relative to the bottom cover 400 under the action of the lifting assembly 300. The brush 110 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a, that is, the brush 110 is displaced in the axial direction of the rotation of the brush assembly 100, that is, the brush 110 falls relative to the driving assembly 200 and approaches or even contacts the surface to be cleaned. The brush 110 can be in contact with the surface to be cleaned, so as to facilitate the normal cleaning of the brush 110 on the surface to be cleaned. The driving assembly 200 drives the brush assembly 100 to rotate in the second direction d2, and the brush 110 rotates with the driving assembly 200 to collect and clean the garbage on the surface to be cleaned. When the cleaning device is used on a wet floor or a cleaning path with liquid, the brush mechanism 1000 of the present application is beneficial to improve the adaptability of the cleaning device.

[0041] In some embodiments, please continue to refer to Figures 1-3 The driving assembly 200 includes a driving motor 210, a transmission module 220 and an output shaft 230. One end of the transmission module 220 is drivingly connected to the driving motor 210, and the other end is drivingly connected to the output shaft 230. The end of the output shaft 230 away from the transmission module 220 is fixedly connected to the brush assembly 100.

[0042] The driving motor 210 serves as a power source for providing driving force to drive the operation of the brush assembly 100. The transmission module 220 is used to transmit the driving force generated by the driving motor 210 to the output shaft 230. The output shaft 230 is used to receive the rotary power from the driving motor 210 and transmit it to the brush assembly 100.

[0043] The driving motor 210 drives the output shaft 230 to rotate along the first direction d1 or the second direction d2 through the transmission module 220. In some embodiments, the first direction d1 and the second direction d2 are opposite directions. When the driving motor 210 drives the output shaft 230 to rotate along the first direction d1, the bristle assembly 100 is driven to rotate along the first direction d1 due to the fixed connection between the output shaft 230 and the bristle assembly 100. When the driving motor 210 drives the output shaft 230 to rotate along the second direction d2, the bristle assembly 100 is driven to rotate along the second direction d2 due to the fixed connection between the output shaft 230 and the bristle assembly 100.

[0044] In some embodiments, please continue to refer to Figures 1-3 The bristle assembly 100 further comprises a fixing block 120. The bristle 110 is spaced apart from the output shaft 230 through the fixing block 120. One end of the fixing block 120 is fixedly connected with the output shaft 230, and the other end is fixedly connected with the bristle 110.

[0045] The fixing block 120 is used to fix the bristle 110, so that the bristle 110 can be assembled to the fixing block 120, and the assembly of the bristle 110 and the output shaft 230 is realized through the assembly of the fixing block 120 and the output shaft 230, which reduces the complexity of part assembly, is conducive to the protection of the output shaft 230, and improves the service life of the driving assembly 200.

[0046] In some embodiments, please continue to refer to Figures 1-3 The lifting assembly 300 further comprises a reduction gearbox 310 and a one-way bearing 320. The output end of the reduction gearbox 310 is provided with an annular slot 311 and a sleeve 312. The sleeve wall of the sleeve 312 is the inner slot wall of the annular slot 311. The one-way bearing 320 is arranged in the annular slot 311 and is sleeved on the outer periphery of the sleeve 312. The one-way bearing 320 is used to rotate along the first direction d1 and rotate along the second direction d2; the first direction d1 and the second direction d2 are opposite directions.

[0047] The reduction gearbox 310 can reduce the high input rotational speed to a low output rotational speed to regulate the rotational speed of the output shaft 230. The annular slot 311 of the reduction gearbox 310 is used to accommodate the one-way bearing 320 and other components to facilitate the miniaturization of the brush mechanism 1000. The sleeve 312 provides the necessary radial support and guidance for the output shaft 230, reduces the axial movement of the output shaft 230, thereby reducing wear and tear and improving efficiency, and enhances the reliability and stability of the normal rotation of the output shaft 230. In some embodiments, the one-way bearing 320 is fixedly arranged in the annular slot 311. Since the one-way bearing 320 is sleeved on the outer periphery of the sleeve 312, the rotation of the one-way bearing 320 and the rotation of the output shaft 230 do not affect each other. The one-way bearing 320 is used to constrain the rotation and / or movement of other parts of the lifting assembly 300, so that the lifting assembly 300 and the brush assembly 100 can operate respectively, so that they can move relative to each other, thereby achieving the lifting or falling of the brush assembly 100 relative to the driving assembly 200.

[0048] In some embodiments, the transmission module 220 is arranged in the reduction gearbox 310. In some embodiments, the reduction gearbox 310 includes an upper cover 310a and a lower cover 310b; the surface of the upper cover 310a is provided with a first through hole, so that the transmission shaft of the driving motor 210 extends into the upper cover 310a and is in transmission connection with one end of the transmission module 220; the surface of the lower cover 310b is provided with a second through hole, so that the output shaft 230 extends into the lower cover 310b and is in transmission connection with the other end of the transmission module 220; the surface of the lower cover 310b away from the upper cover 310a is provided with an annular slot 311, and the part of the lower cover 310b surrounded by the annular slot 311 is provided with a second through hole to form a sleeve 312, so that the output shaft 230 extends out of the sleeve 312 to drive the rotation of the brush assembly 100. In some embodiments, the upper cover 310a is provided with a copper ring, and the output shaft 230 is arranged in the copper ring.

[0049] In some embodiments, please continue to refer to Figures 1-3 , the lifting assembly 300 includes a rotation-stopping sliding block 330, which is sleeved on the outer periphery of the one-way bearing 320 and is in sliding connection with the one-way bearing 320, the brush 110 is arranged between the rotation-stopping sliding block 330 and the bottom cover 400, and the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 400 is smaller than the thickness of the brush 110.

[0050] Wherein, the rotation-stopping sliding block 330 can rotate or stop rotating with the one-way bearing 320. Since the brush 110 is arranged between the rotation-stopping sliding block 330 and the bottom cover 400, and the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 400 is smaller than the thickness of the brush 110, when the brush 110 is located in the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 400, the brush 110 is warped, and an acting force is generated on the rotation-stopping sliding block 330, due to the sliding connection between the rotation-stopping sliding block 330 and the one-way bearing 320, the acting force generated on the rotation-stopping sliding block 330 pushes the rotation-stopping sliding block 330 to move in the axial direction of the brush assembly 100 towards the driving assembly 200, for example, when the brush 110 rotates relative to the bottom cover 400 in the first direction d1 under the action of the lifting assembly 300, the brush 110 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b thereof, i.e. the brush 110 is lifted relative to the surface to be cleaned, and the rotation-stopping sliding block 330 also moves in the axial direction of the brush assembly 100 towards the driving assembly 200.

[0051] When the brush 110 moves out of the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 400, the acting force of the brush 110 on the rotation-stopping sliding block 330 decreases, and the rotation-stopping sliding block 330 moves in the axial direction of the brush assembly 100 away from the driving assembly 200, i.e. the rotation-stopping sliding block 330 falls relative to the driving assembly 200, for example, when the brush 110 rotates relative to the bottom cover 400 in the second direction d2 under the action of the lifting assembly 300, the brush 110 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a thereof, i.e. the brush 110 falls relative to the driving assembly 200, and the rotation-stopping sliding block 330 also moves in the axial direction of the brush assembly 100 away from the driving assembly 200.

[0052] Please refer to Figures 5-6 , Figure 5 is Figure 1 the structure diagram of the rotation-stopping sliding block of the brush mechanism shown in Figure 6 is Figure 1 the structure diagram of the speed reducer of the brush mechanism shown in.

[0053] In some embodiments, referring to Figures 3-4 , the rotation-stopping sliding block 330 is provided with a plurality of first protrusions 330a on one side thereof towards the annular slot 311, and the bottom of the annular slot 311 is provided with a plurality of second protrusions 311a, in response to the movement of the brush 110 along the inclined surface 4111 towards the driving assembly 200, the rotation-stopping sliding block 330 moves towards the driving assembly 200, and the first protrusions 330a and the second protrusions 311a are staggered; in response to the movement of the brush 110 along the inclined surface 4111 away from the driving assembly 200, the rotation-stopping sliding block 330 moves away from the driving assembly 200, and the first protrusions 330a and the second protrusions 311a are separated.

[0054] When the brush 110 rotates relative to the bottom cover 400 in the first direction d1 under the action of the lifting assembly 300, the brush 110 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b, i.e. the brush 110 is lifted relative to the surface to be cleaned, and the rotation-stopping sliding block 330 also moves in the axial direction of the rotation of the brush assembly 100 towards the driving assembly 200, the first protrusion 330a of the rotation-stopping sliding block 330 is staggered with the second protrusion 311a of the annular slot 311, and the rotation-stopping sliding block 330 is "locked" to the speed reducer 310.

[0055] When the brush 110 rotates relative to the bottom cover 400 in the second direction d2 under the action of the lifting assembly 300, the brush 110 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a, i.e. the brush 110 falls relative to the driving assembly 200, and the rotation-stopping sliding block 330 also moves in the axial direction of the rotation of the brush assembly 100 away from the driving assembly 200, the first protrusion 330a of the rotation-stopping sliding block 330 is separated from the second protrusion 311a of the annular slot 311, the rotation-stopping sliding block 330 is "unlocked" from the speed reducer 310, the freedom of the one-way bearing 320 is released, and the bottom cover 400 is driven to rotate synchronously with the brush assembly 100, thereby gathering and cleaning the garbage objects on the surface to be cleaned through rotation.

[0056] Please refer to Figure 7 , Figure 7 is Figure 1 the cross-sectional structure diagram of the speed reducer and the rotation-stopping sliding block of the brush mechanism.

[0057] In some embodiments, referring to Figure 7 , the first protrusion 330a and / or the second protrusion 311a has a slope S1 relative to the axial direction of the output shaft 230, in the case that the first protrusion 330a and the second protrusion 311a abut and press each other, the first protrusion 330a and the second protrusion 311a can be relatively moved through the slope S1 when the rotation-stopping sliding block 330 and the annular slot 311 relatively move, so as to change the state from abutting and pressing each other to misfitting each other, thereby reducing the damage to the components of the brush mechanism 1000. In some embodiments, the slope S1 can be a straight slope or a curved slope.

[0058] In some embodiments, referring to Figures 1-3 , the lifting assembly 300 includes a plug 340 and a damping member 350. The plug 340 is sleeved on the outer periphery of the one-way bearing 320. The damping member 350 is arranged between the plug 340 and the rotation-stopping sliding block 330.

[0059] The plug 340 is used to limit and constrain the damping member 350, so that the damping member 350 can operate normally. The damping member 350 is used to accumulate and release stress, so that the rotation stopper 330 can keep the edge brush 110 in a pressed state, thereby improving the cleaning ability of the edge brush assembly 100. In some embodiments, the damping member 350 is a spring.

[0060] When the edge brush 110 rotates relative to the bottom cover 400 in the first direction d1 under the action of the lifting assembly 300, the edge brush 110 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b thereof, i.e., the edge brush 110 is lifted relative to the surface to be cleaned, and the rotation stopper 330 also moves along the axial direction of the rotation of the edge brush assembly 100 towards the driving assembly 200, so that the damping member 350 is compressed.

[0061] When the edge brush 110 rotates relative to the bottom cover 400 in the second direction d2 under the action of the lifting assembly 300, the edge brush 110 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a thereof, i.e., the edge brush 110 falls relative to the driving assembly 200, and the rotation stopper 330 also moves along the axial direction of the rotation of the edge brush assembly 100 away from the driving assembly 200, so that the damping member 350 releases stress and pushes the rotation stopper 330 to move along the axial direction of the rotation of the edge brush assembly 100 away from the driving assembly 200, thereby keeping the edge brush 110 in a pressed state.

[0062] In some embodiments, please continue to refer to Figures 1-3 The lifting assembly 300 includes a bottom cover fixing block 360. The bottom cover fixing block 360 is sleeved on the outer periphery of the one-way bearing 320 and is fixedly connected with the bottom cover 400. The edge brush 110 is arranged between the bottom cover fixing block 360 and the bottom cover 400.

[0063] The bottom cover fixing block 360 is used to fix the bottom cover 400. The bottom cover fixing block 360 rotates with the one-way bearing 320, thereby driving the bottom cover 400 to rotate with the one-way bearing 320.

[0064] In some embodiments, please continue to refer to Figures 1-5 The rotation stopper 330 has a hollow inner ring 331, and the inner ring 331 is provided with a plurality of grooves 3311. The bottom cover fixing block 360 is provided with a plurality of protrusions 361 close to one end of the bottom cover 400. The number of the protrusions 361 matches the number of the grooves 3311, and the protrusions 361 are assembled into the grooves 3311 of the rotation stopper 330 in response to the bottom cover fixing block 360. The protrusions 361 and the inner walls of the grooves 3311 have a gap.

[0065] The protrusion 361 of the bottom cover fixing block 360 is inserted into the groove 3311 of the rotation-stopping sliding block 330 to realize the assembly of the bottom cover fixing block 360 and the rotation-stopping sliding block 330. The protrusion 361 and the inner wall of the groove 3311 have a gap, which provides a certain fault tolerance space for the bottom cover fixing block 360 and the rotation-stopping sliding block 330. In the case that the first protrusion 330a and the second protrusion 311a abut and extrude each other, due to the existence of the gap, the one-way bearing 320 and the bottom cover fixing block 360 can move relative to the rotation-stopping sliding block 330 to a certain extent, that is, the rotation-stopping sliding block 330 moves relative to the speed reducer 310 to a certain extent, so that the first protrusion 330a and the second protrusion 311a move relative to each other, and the state of abutting and extruding each other changes to the state of dislocation, so as to reduce the damage to the parts of the side brush mechanism 1000.

[0066] Referring to Figure 8 , Figure 8 is a structural schematic diagram of a cleaning device provided by an embodiment of the present application.

[0067] Referring to Figure 8 , an embodiment of the present application provides a cleaning device 3000. The cleaning device 3000 comprises a device main body 2000 and any side brush mechanism 1000 provided in the first aspect. The side brush mechanism 1000 is arranged on the device main body 2000.

[0068] The cleaning device 3000 is used for cleaning work. The cleaning device 3000 is, for example, a sweeping robot, a cleaning robot or a dust collector, and can have one or more cleaning functions such as dust collection, sweeping, mopping and washing. Optionally, the cleaning device 3000 can be a self-walking cleaning device 3000, which can walk autonomously or under instruction control, and then perform cleaning work.

[0069] The device main body 2000 is used for walking on a surface to be cleaned, so as to collect, suck and store garbage objects. Specifically, the device main body 2000 can have a sweeping function or a dust collection function, and of course can have both sweeping and dust collection functions, and can also have other cleaning functions. The device main body 2000 is used for sucking and storing garbage objects.

[0070] The device body 2000 can be provided with a fan for providing an air volume, for example, the air volume of the fan flowing through the air per unit time. The greater the air volume, the more air containing garbage objects is sucked into the cleaning device 3000 per unit time. Under the action of the air volume provided by the fan and directed to the inside of the device body 2000, the cleaning device 3000 will suck in the air containing garbage objects, thereby achieving the purpose of cleaning. The device body 2000 can also include a dust box, which can be installed in the device body 2000 by insertion, assembly, combination, etc. The dust box can be used to store dust, debris and other garbage objects. The device body 2000 can also include a walking assembly, which can enable the cleaning device 3000 to have a movable function. The walking assembly can include a driving mechanism and a rolling wheel mechanism. The driving mechanism is used to drive the rolling wheel mechanism to rotate, so that the cleaning device 3000 can walk on the working surface. The driving mechanism is, for example, a motor. The device body 2000 can also include a sensing assembly for realizing one or more corresponding functions, such as infrared function, collision sensing function, etc., which can be used to realize obstacle avoidance, navigation, recharging, etc. The device body 2000 can also include a control circuit, which can be coupled to the walking assembly, the brush mechanism 1000, the fan and the sensing assembly, etc. respectively, and can be used to control the operation of the above-mentioned assemblies to realize the corresponding operation. The control circuit can be an MCU, or a circuit board including an MCU, which serves as the processing hub of the cleaning device 3000.

[0071] The brush mechanism 1000 is arranged on the device body 2000 and is used to contact the surface to be cleaned to gather and clean the garbage objects on the surface to be cleaned by rotating.

[0072] The lifting, falling and normal operation of the brush assembly 100 are described in detail below.

[0073] When the cleaning device 3000 cleans the surface to be cleaned, the driving assembly 200 drives the brush assembly 100 to rotate in the second direction d2. The brush 110 rotates in the second direction d2 along with the driving assembly 200, and the bottom cover 400 rotates synchronously with the brush 110. The brush assembly 100 and the lifting assembly 300 rotate synchronously, and the garbage objects on the surface to be cleaned are gathered and cleaned by rotating.

[0074] When the cleaning device 3000 detects liquid in front of the cleaning device 3000, and the brush arm side brush 110 needs to be lifted, the driving assembly 200 drives the side brush assembly 100 to rotate along the first direction d1, since the one-way bearing 320 is locked in the first direction d1, the bottom cover 400 is also locked in the first direction d1, and the side brush 110 rotates relative to the bottom cover 400, since the bottom cover 400 includes the inclined surface 4111, the side brush 110 moves along the inclined surface 4111 towards the driving assembly 200, i.e. the side brush 110 is lifted relative to the surface to be cleaned. Since the minimum gap between the locking block 330 and the bottom cover 400 is smaller than the thickness of the side brush 110, when the side brush 110 is located in the minimum gap between the locking block 330 and the bottom cover 400, the side brush 110 is warped, and an acting force is generated on the locking block 330, since the locking block 330 is in sliding connection with the one-way bearing 320, the acting force generated on the locking block 330 pushes the locking block 330 to displace along the axial direction of the rotation of the side brush assembly 100 towards the driving assembly 200, the first protrusion 330a of the locking block 330 and the second protrusion 311a of the annular slot 311 of the reduction box 310 are staggered, and the locking block 330 is “locked” to the reduction box 310, i.e. the lifting assembly 300 is “locked” to the reduction box 310.

[0075] When the cleaning device 3000 needs the side brush 110 to fall to re-contact the surface to be cleaned, the driving assembly 200 drives the side brush assembly 100 to rotate along the second direction d2, since the one-way bearing 320 rotates along the second direction d2, the bottom cover 400 should also rotate along the second direction d2, but since the one-way bearing 320 is “locked” to the reduction box 310 when the side brush 110 is lifted, it cannot rotate, and thus the bottom cover 400 also does not rotate, therefore, in the stage when the one-way bearing 320 is “locked” to the reduction box 310, the side brush 110 can rotate along the second direction d2, and the bottom cover 400 is locked along the second direction d2, and the side brush 110 rotates relative to the bottom cover 400 along the second direction d2, so that the side brush 110 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a thereof, i.e. the side brush 110 displaces along the axial direction of the rotation of the side brush assembly 100, i.e. the side brush 110 falls relative to the driving assembly 200.

[0076] As the bristle brush 110 falls relative to the driving assembly 200, the rotation-stopping slider 330 also moves in the axial direction of the rotation of the bristle brush assembly 100 away from the driving assembly 200, the damping member 350 releases stress, pushes the rotation-stopping slider 330 to move in the axial direction of the rotation of the bristle brush assembly 100 away from the driving assembly 200, maintains the state of pressing the bristle brush 110, and then the first protrusion 330a of the rotation-stopping slider 330 is separated from the second protrusion 311a of the annular slot 311, the rotation-stopping slider 330 is "unlocked" from the speed reducer 310, the freedom of the one-way bearing 320 is released, the bottom cover 400 is driven to rotate synchronously with the bristle brush assembly 100, and the garbage objects on the surface to be cleaned are gathered and cleaned by rotation.

[0077] In summary, by providing the bristle brush assembly 100, the driving assembly 200, the lifting assembly 300, and the bottom cover 400 in the bristle brush mechanism 1000, the bottom cover 400 includes the inclined surface 4111, the bristle brush assembly 100 is slidingly fitted on the inclined surface 4111, the inclined surface 4111 has the first end 4111a towards the bottom cover 400 and the second end 4111b towards the driving assembly 200, the driving assembly 200 and the lifting assembly 300 are used to control the bristle brush 110 to move along the inclined surface 4111 towards or away from the driving assembly 200, so that the bristle brush 110 is lifted or falls relative to the surface to be cleaned, or rotates with the driving assembly 200, so that the bristle brush assembly 100 normally operates. When the ground is wet or there is liquid on the cleaning path, the bristle brush mechanism 1000 of the present application is beneficial to improve the use adaptability of the cleaning device 3000.
