[0035] Current cleaning equipment usually gathers and sweeps debris and hair around the cleaning equipment through a rotating side brush, and then absorbs the dust through the suction port of the cleaning equipment. However, when using a cleaning equipment to clean a surface to be cleaned, there may not only be solid garbage objects, dust, etc. on the surface to be cleaned, but also liquid sewage, stagnant liquid, etc. that need to be cleaned with a rag or mop. When the rotating side brush encounters sewage, the sewage area will increase or even splash, making cleaning more difficult. Therefore, the present application proposes the following embodiments to solve the above technical problems.

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

[0037] See also Figure 1 to Figure 4 , Figure 1is a schematic diagram of the structure of the side brush mechanism provided in an embodiment of the present application, Figure 2 yes Figure 1 The cross-sectional structure diagram of the side brush mechanism shown in FIG. Figure 3 yes Figure 1 An exploded schematic diagram of the side brush mechanism shown, Figure 4 yes Figure 1 A schematic structural diagram of the bottom cover of the side brush mechanism shown.

[0038] See also Figure 1 to Figure 4 , an embodiment of the present application provides a side brush mechanism 1000. The side brush mechanism 1000 includes a side brush assembly 100, a drive assembly 200, a lifting assembly 300 and a bottom cover 400. Among them, the side brush assembly 100 includes at least one side brush 110. The drive assembly 200 is connected to the side brush assembly 100 to drive the side brush assembly 100 to rotate. The lifting assembly 300 is linked with the side brush assembly 100 and the drive assembly 200. The bottom cover 400 is arranged at the end of the output shaft 230 of the drive assembly 200. The bottom cover 400 is provided with a flange 410 facing the drive assembly 200 at its periphery, and the flange 410 has a notch 411, and the side wall of the notch 411 includes an inclined surface 4111 inclined relative to the drive assembly 200, and the side brush assembly 100 is slidably matched with the inclined surface 4111. The driving assembly 200 and the lifting assembly 300 are used to control the side brush 110 to move along the inclined surface 4111 toward or away from the driving assembly 200 or to rotate with the driving assembly 200 .

[0039] In some embodiments, the side brush 110 includes a side brush body and a side brush cleaning portion, and the side brush cleaning portion is spaced apart from the driving assembly 200 through the side brush body. In some embodiments, the side brush body and the side brush cleaning portion are detachably connected to facilitate replacement of one or both of the side brush body and the side brush cleaning portion, thereby improving the utilization rate of parts. In some embodiments, the side brush cleaning portion is made of a flexible material such as a rubber material and / or a silicone material, so as to improve the protection of the surface to be cleaned when cleaning the surface to be cleaned.

[0040] In some embodiments, see Figure 4The first end 4111a and the second end 4111b of the inclined surface 4111 are spaced apart along the direction of rotation of the side brush assembly 100, 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 side brush assembly 100 to rotate along the first direction d1, and the side brush 110 rotates relative to the bottom cover 400 along the first direction d1 under the action of the lifting assembly 300, and the side brush 110 moves along the first end 4111a of the inclined surface 4111 toward the second end 4111b thereof, that is, the side brush 110 is displaced along the axial direction of rotation of the side brush assembly 100, that is, the side brush 110 is lifted relative to the surface to be cleaned and away from the surface to be cleaned, so as to reduce the side brush 110 from touching the liquid on the surface to be cleaned, reduce the possibility of the liquid area increasing or even splashing due to the rotation of the side brush 110, and improve the adaptability of the side brush mechanism 1000 to different cleaning environments. The driving assembly 200 drives the side brush assembly 100 to rotate along the second direction d2, and the side brush 110 rotates relative to the bottom cover 400 along the second direction d2 under the action of the lifting assembly 300, and the side brush 110 moves along the second end 4111b of the inclined surface 4111 toward the first end 4111a thereof, that is, the side brush 110 is displaced along the axial direction of the rotation of the side brush assembly 100, that is, the side brush 110 falls relative to the driving assembly 200, approaches or even contacts the surface to be cleaned, and the side brush 110 can contact the surface to be cleaned, so that the side brush 110 can normally clean the surface to be cleaned. The driving assembly 200 drives the side brush assembly 100 to rotate along the second direction d2, and the side brush 110 rotates with the driving assembly 200, and gathers and cleans the garbage objects on the surface to be cleaned by rotation. When there is liquid on a wet ground or on the cleaning path, the setting of the side brush mechanism 1000 of the present application is conducive to improving the adaptability of the cleaning equipment.

[0041] In some embodiments, see Figure 1 to Figure 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 connected to the driving motor 210, and the other end is connected to the output shaft 230. One end of the output shaft 230 away from the transmission module 220 is fixedly connected to the side brush assembly 100.

[0042] The drive motor 210 is used as a power source to provide driving force to drive the side brush assembly 100. The transmission module 220 is used to transmit the driving force generated by the drive motor 210 to the output shaft 230. The output shaft 230 is used to receive the rotational power from the drive motor 210 and transmit it to the side 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. When the driving motor 210 drives the output shaft 230 to rotate along the first direction d1, since the output shaft 230 is fixedly connected to the side brush assembly 100, the side brush assembly 100 is also driven to rotate along the first direction d1. When the driving motor 210 drives the output shaft 230 to rotate along the second direction d2, since the output shaft 230 is fixedly connected to the side brush assembly 100, the side brush assembly 100 is also driven to rotate along the second direction d2.

[0044] In some embodiments, see Figure 1 to Figure 3 The side brush assembly 100 further includes a fixing block 120. The side brush 110 is spaced apart from the output shaft 230 through the fixing block 120. One end of the fixing block 120 is fixedly connected to the output shaft 230, and the other end is fixedly connected to the side brush 110.

[0045] Among them, the fixing block 120 is used to fix the side brush 110, so that the side brush 110 can be assembled on the fixing block 120, and the assembly with the output shaft 230 is realized by assembling the fixing block 120 and the output shaft 230, which reduces the complexity of parts assembly, is beneficial to the protection of the output shaft 230, and improves the service life of the drive assembly 200.

[0046] In some embodiments, see Figure 1 to Figure 3 The lifting assembly 300 further includes a reduction box 310 and a one-way bearing 320. The output end of the reduction box 310 is provided with an annular groove 311 and a sleeve 312. The cylinder wall of the sleeve 312 is the inner groove wall of the annular groove 311. The one-way bearing 320 is arranged in the annular groove 311 and sleeved on the outer periphery of the sleeve 312. The one-way bearing 320 is used to stop rotation along the first direction d1 and rotate along the second direction d2; the first direction d1 and the second direction d2 are opposite directions to each other.

[0047] Among them, the reduction box 310 can reduce the high-speed input speed to a low output speed to adjust the rotation speed of the output shaft 230. The annular groove 311 of the reduction box 310 is used to accommodate components such as the one-way bearing 320, so as to facilitate the miniaturization of the side brush mechanism 1000. The sleeve 312 provides necessary radial support and guidance for the output shaft 230, reduces the axial movement of the output shaft 230, thereby reducing wear and improving efficiency, and improving the reliability and stability of the normal rotation of the output shaft 230. In some embodiments, the one-way bearing 320 is fixedly arranged on the annular groove 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 side brush assembly 100 can operate separately, so that the two can move relative to each other, thereby realizing the lifting or falling of the side brush assembly 100 relative to the driving assembly 200.

[0048] In some embodiments, the transmission module 220 is disposed in the reduction box 310. In some embodiments, the reduction box 310 includes an upper cover 310a and a lower cover 310b; a first through hole is provided on the surface of the upper cover 310a, so that the transmission shaft of the driving motor 210 extends from the first through hole into the upper cover 310a and is transmission-connected with one end of the transmission module 220; a second through hole is provided on the surface of the lower cover 310b, so that the output shaft 230 extends from the second through hole into the lower cover 310b and is transmission-connected with the other end of the transmission module 220; an annular groove 311 is provided on the surface of the lower cover 310b away from the upper cover 310a, and a second through hole is provided on the portion of the lower cover 310b surrounded by the annular groove 311 to form a sleeve 312, so that the output shaft 230 extends from the sleeve 312 to drive the side brush assembly 100 to rotate. In some embodiments, a copper ring is provided on the upper cover 310a, and the output shaft 230 is provided in the copper ring.

[0049] In some embodiments, see Figure 1 to Figure 3 The lifting assembly 300 includes a stop slider 330, which is slidably mounted on the outer periphery of the one-way bearing 320 and is slidably connected to the one-way bearing 320. The side brush 110 is arranged between the stop slider 330 and the bottom cover 400, and the minimum gap between the stop slider 330 and the bottom cover 400 is smaller than the thickness of the side brush 110.

[0050] The anti-rotation slider 330 can rotate or stop rotating together with the one-way bearing 320. Since the side brush 110 is arranged between the anti-rotation slider 330 and the bottom cover 400, and the minimum gap between the anti-rotation slider 330 and the bottom cover 400 is smaller than the thickness of the side brush 110, when the side brush 110 is located at the minimum gap between the anti-rotation slider 330 and the bottom cover 400, the side brush 110 is warped and a force is generated on the anti-rotation slider 330. Due to the sliding connection between the anti-rotation slider 330 and the one-way bearing 320, the force generated on the anti-rotation slider 330 pushes the anti-rotation slider 330 is displaced toward the driving assembly 200 along the axial direction of rotation of the side brush assembly 100. For example, when the side brush 110 rotates along the first direction d1 relative to the bottom cover 400 under the action of the lifting assembly 300, the side brush 110 moves along the first end 4111a of the inclined surface 4111 toward its second end 4111b, that is, the side brush 110 is lifted relative to the surface to be cleaned, and the anti-rotation slider 330 also moves toward the driving assembly 200 along the axial direction of rotation of the side brush assembly 100.

[0051] When the side brush 110 moves out of the minimum gap between the anti-rotation slider 330 and the bottom cover 400, the force of the side brush 110 on the anti-rotation slider 330 is reduced, and the anti-rotation slider 330 is displaced along the axial direction of rotation of the side brush assembly 100 away from the drive assembly 200, that is, the anti-rotation slider 330 falls relative to the drive assembly 200. For example, when the side brush 110 rotates along the second direction d2 relative to the bottom cover 400 under the action of the lifting assembly 300, the side brush 110 moves along the second end 4111b of the inclined surface 4111 toward the first end 4111a thereof, that is, the side brush 110 falls relative to the drive assembly 200, and the anti-rotation slider 330 also moves along the axial direction of rotation of the side brush assembly 100 away from the drive assembly 200.

[0052] See also Figure 5-6 , Figure 5 yes Figure 1 The structural schematic diagram of the anti-rotation slider of the side brush mechanism shown in FIG. Figure 6 yes Figure 1 A schematic structural diagram of the reduction gearbox of the side brush mechanism shown.

[0053] In some embodiments, see Figure 3-4 A plurality of first protrusions 330a are provided on the side of the anti-rotation slider 330 facing the annular groove 311, and a plurality of second protrusions 311a are provided at the bottom of the annular groove 311. In response to the side brush 110 moving along the inclined surface 4111 toward the driving assembly 200, the anti-rotation slider 330 moves toward the driving assembly 200, and the first protrusions 330a and the second protrusions 311a are staggered; in response to the side brush 110 moving along the inclined surface 4111 away from the driving assembly 200, the anti-rotation slider 330 moves away from the driving assembly 200, and the first protrusions 330a and the second protrusions 311a are separated.

[0054] Among them, when the side brush 110 rotates along the first direction d1 relative to the bottom cover 400 under the action of the lifting assembly 300, the side brush 110 moves along the first end 4111a of the inclined surface 4111 toward its second end 4111b, that is, the side brush 110 is lifted relative to the surface to be cleaned, and the anti-rotation slider 330 also moves toward the driving assembly 200 along the axial direction of rotation of the side brush assembly 100, and the first protrusion 330a of the anti-rotation slider 330 is staggered with the second protrusion 311a of the annular groove 311, and the anti-rotation slider 330 is "locked" on the reduction box 310.

[0055] When the side brush 110 rotates along the second direction d2 relative to the bottom cover 400 under the action of the lifting assembly 300, the side brush 110 moves along the second end 4111b of the inclined surface 4111 toward its first end 4111a, that is, the side brush 110 falls relative to the driving assembly 200, and the anti-rotation slider 330 also moves away from the driving assembly 200 along the axial direction of rotation of the side brush assembly 100, and the first protrusion 330a of the anti-rotation slider 330 is separated from the second protrusion 311a of the annular groove 311, and the anti-rotation slider 330 is "unlocked" on the reduction box 310, and the freedom of the one-way bearing 320 is released, driving the bottom cover 400 and the side brush assembly 100 to rotate synchronously, and garbage objects on the surface to be cleaned are gathered and cleaned through rotation.

[0056] See also Figure 7 , Figure 7 yes Figure 1 The cross-sectional structure diagram of the reduction gearbox and anti-rotation slider of the side brush mechanism shown.

[0057] In some embodiments, see Figure 7 The first protrusion 330a and / or the second protrusion 311a have an inclined surface S1 relative to the axial direction of the output shaft 230. When the first protrusion 330a and the second protrusion 311a abut against and squeeze each other, when the anti-rotation slider 330 and the annular groove 311 move relative to each other, the inclined surface S1 facilitates the first protrusion 330a and the second protrusion 311a to move relative to each other, and change from a state of abutting and squeezing each other to a state of mutual dislocation, so as to reduce damage to the parts of the side brush mechanism 1000. In some embodiments, the inclined surface S1 can be an inclined straight surface or an inclined curved surface.

[0058] In some embodiments, see Figure 1 to Figure 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 anti-rotation slider 330.

[0059] The plug 340 is used to limit and constrain the damping member 350 to facilitate the normal operation of the damping member 350. The damping member 350 is used to accumulate and release stress so that the anti-rotation slider 330 can maintain the downward pressure on the side brush 110, thereby improving the cleaning ability of the side brush assembly 100. In some embodiments, the damping member 350 is a spring.

[0060] When the side brush 110 rotates along the first direction d1 relative to the bottom cover 400 under the action of the lifting assembly 300, the side brush 110 moves along the first end 4111a of the inclined surface 4111 toward its second end 4111b, that is, the side brush 110 is lifted relative to the surface to be cleaned, and the anti-rotation slider 330 also moves toward the driving assembly 200 along the axial direction of rotation of the side brush assembly 100, and the damping member 350 is compressed.

[0061] When the side brush 110 rotates along the second direction d2 relative to the bottom cover 400 under the action of the lifting assembly 300, the side brush 110 moves along the second end 4111b of the inclined surface 4111 toward its first end 4111a, that is, the side brush 110 falls relative to the driving assembly 200, and the anti-rotation slider 330 also moves along the axial direction of rotation of the side brush assembly 100 away from the driving assembly 200, and the damping member 350 releases stress, pushing the anti-rotation slider 330 to move along the axial direction of rotation of the side brush assembly 100 away from the driving assembly 200, thereby maintaining the downward pressure on the side brush 110.

[0062] In some embodiments, see Figure 1 to Figure 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 to the bottom cover 400. The side brush 110 is disposed 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 rotation of the one-way bearing 320, thereby driving the bottom cover 400 to rotate with the rotation of the one-way bearing 320.

[0064] In some embodiments, see Figure 1 to Figure 5 The anti-rotation slider 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 at one end close to the bottom cover 400. The number of the protrusions 361 matches that of the grooves 3311, and in response to the protrusions 361 of the bottom cover fixing block 360 being assembled to the grooves 3311 of the anti-rotation slider 330, there is a gap between the protrusions 361 and the inner wall of the groove 3311.

[0065] The protrusion 361 of the bottom cover fixing block 360 is inserted into the groove 3311 of the anti-rotation slider 330 to realize the assembly of the bottom cover fixing block 360 and the anti-rotation slider 330. There is a gap between the protrusion 361 and the inner wall of the groove 3311, which provides a certain fault tolerance space for the bottom cover fixing block 360 and the anti-rotation slider 330. In the case where the first protrusion 330a and the second protrusion 311a abut and squeeze each other, due to the existence of the gap, the one-way bearing 320 and the bottom cover fixing block 360 can have a certain degree of relative movement relative to the anti-rotation slider 330, that is, the anti-rotation slider 330 has a certain degree of relative movement relative to the reduction box 310, so that the first protrusion 330a and the second protrusion 311a have relative movement, and the state of mutual abutment and squeezing is changed to a state of mutual dislocation, so as to reduce the damage to the parts of the side brush mechanism 1000.

[0066] See also Figure 8 , Figure 8 It is a schematic diagram of the structure of the cleaning device provided in the embodiment of the present application.

[0067] See also Figure 8 , an embodiment of the present application provides a cleaning device 3000. The cleaning device 3000 includes a device body 2000 and any side brush mechanism 1000 as provided in the first aspect. The side brush mechanism 1000 is disposed on the device body 2000.

[0068] The cleaning device 3000 is used to perform cleaning work. The cleaning device 3000 is, for example, a sweeping robot, a cleaning robot or a vacuum cleaner, and may have one or more cleaning functions such as vacuuming, sweeping, mopping and washing. Optionally, the cleaning device 3000 may be a self-propelled cleaning device 3000 that can walk autonomously or under command control to perform cleaning work.

[0069] The device body 2000 is used to walk on the surface to be cleaned so as to collect, suck and store garbage objects. Specifically, the device body 2000 can have a cleaning function or a dust suction function, and can also have a cleaning function and a dust suction function, and can also have other cleaning functions. The device body 2000 is used to suck and store garbage objects.

[0070] A fan may be provided in the device body 2000, and the fan is used to provide air volume. The air volume provided by the fan is, for example, the amount of air flowing through the fan 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 directed to the inside of the device body 2000 provided by the fan, the cleaning device 3000 will suck in the air containing garbage objects, thereby achieving the purpose of cleaning. The device body 2000 may also include a dust box, which may be installed in the device body 2000 by insertion, assembly, combination, etc. The dust box may be used to store garbage objects such as dust and debris. The device body 2000 may also include a walking component, which may make the cleaning device 3000 movable. The walking component may include a driving mechanism and a rolling wheel mechanism, and the driving mechanism is used to drive the rolling wheel mechanism to rotate, so as to achieve walking on the working surface of the cleaning device 3000. The driving mechanism is, for example, a motor. The device body 2000 may also include a sensor component, which is used to implement one or more corresponding functions, such as infrared function, collision sensing function, etc., and can be used to implement functions such as obstacle avoidance, navigation, and recharging. The device body 2000 may also include a control circuit, which can be coupled to the walking component, the side brush mechanism 1000, the fan, and the sensor component, etc., respectively, and can be used to control the operation of the above components to achieve corresponding operations. The control circuit can be an MCU, or a circuit board including an MCU, as the processing center of the cleaning device 3000.

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

[0072] The following describes in detail the movement process of lifting, falling and normal operation of the side brush assembly 100.

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

[0074] When the cleaning device 3000 detects that there is liquid in front and the side brush 110 of the brush arm 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 stops rotating along the first direction d1, the bottom cover 400 also stops rotating along the first direction d1, and the side brush 110 rotates relative to the bottom cover 400. Since the bottom cover 400 includes an inclined surface 4111, the side brush 110 moves along the inclined surface 4111 toward the driving assembly 200, that is, the side brush 110 is lifted relative to the surface to be cleaned. Since the minimum gap between the anti-rotation slider 330 and the bottom cover 400 is smaller than the thickness of the side brush 110, when the side brush 110 is located at the minimum gap between the anti-rotation slider 330 and the bottom cover 400, the side brush 110 warps and generates a force on the anti-rotation slider 330. Due to the sliding connection between the anti-rotation slider 330 and the one-way bearing 320, the force generated on the anti-rotation slider 330 pushes the anti-rotation slider 330 to move along the axial direction of rotation of the side brush assembly 100 toward the driving assembly 200. The first protrusion 330a of the anti-rotation slider 330 is staggered with the second protrusion 311a of the annular groove 311 of the reduction box 310, and the anti-rotation slider 330 is "locked" to the reduction box 310, that is, 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. However, 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 does not rotate either. 0 is "locked" in the reduction gear box 310, the side brush 110 can rotate along the second direction d2, 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 toward the first end 4111a thereof, that is, the side brush 110 is displaced along the axial direction of the rotation of the side brush assembly 100, that is, the side brush 110 falls relative to the driving assembly 200.

[0076] As the side brush 110 falls relative to the driving assembly 200, the anti-rotation slider 330 also moves along the axial direction of the rotation of the side brush assembly 100 away from the driving assembly 200, and the damping member 350 releases stress, pushing the anti-rotation slider 330 to move along the axial direction of the rotation of the side brush assembly 100 away from the driving assembly 200, maintaining the downward pressure on the side brush 110, and then the first protrusion 330a of the anti-rotation slider 330 is separated from the second protrusion 311a of the annular groove 311, and the anti-rotation slider 330 is "unlocked" from the reduction box 310, and the freedom of the one-way bearing 320 is released, driving the bottom cover 400 and the side brush assembly 100 to rotate synchronously, and garbage objects on the surface to be cleaned are gathered and cleaned through rotation.

[0077] In summary, by arranging the side brush assembly 100, the drive assembly 200, the lifting assembly 300 and the bottom cover 400 in the side brush mechanism 1000, the bottom cover 400 includes an inclined surface 4111, the side brush assembly 100 is slidably matched with the inclined surface 4111, the inclined surface 4111 has a first end 4111a facing the bottom cover 400 and a second end 4111b facing the drive assembly 200, and the drive assembly 200 and the lifting assembly 300 are used to control the side brush 110 to move toward or away from the drive assembly 200 along the inclined surface 4111, so that the side brush 110 is lifted or dropped relative to the surface to be cleaned, or rotated with the drive assembly 200, so that the side brush assembly 100 operates normally. When the side brush mechanism 1000 of the present application is used for wet ground or when there is liquid on the cleaning path, the setting of the side brush mechanism 1000 of the present application is conducive to improving the adaptability of the cleaning device 3000.
