[0002] Handheld cleaning devices are popular among consumers due to their compact structure and ease of use. Currently, manual cleaning devices are mostly used on the market to clean soft surfaces such as sofas, car seats, and carpets. When using this type of product, users spray water on the drum to clean the work surface by rotating the drum on the work surface. After cleaning, the dirt on the work surface needs to be sucked away through the suction channel.

[0040] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0043] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] The specific embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0045] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0046] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the prerequisite for each other's existence.

[0047] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0048] The present disclosure provides a cleaning device, which can be a handheld cleaning device, such as a handheld vacuum cleaner or a handheld floor scrubber; it can also be a sweeping robot or a mopping robot. The cleaning device includes a main body, a floor brush assembly, and a dirt suction assembly rotatably connected to the underside of the main body. During use, the floor brush assembly rotates to clean the work surface, and the dirt suction assembly removes any remaining dirt after cleaning, thereby cleaning the work surface.

[0049] In the cleaning device disclosed herein, the floor brush assembly is rotatably connected to the body. When the floor brush assembly is working, the floor brush assembly rotates relative to the body and contacts the working surface during the rotation process, thereby cleaning the dirt on the working surface.

[0050] The positional relationship between the sewage suction port and the floor brush assembly is as follows: when the body is rotated to a first predetermined angle relative to the work surface, the sewage suction port can be brought into contact with the work surface; the sewage suction assembly is configured to suck in the dirt on the work surface after the sewage suction port is brought into contact with the work surface.

[0051] The cleaning device disclosed herein has a sewage suction port positioned on the body such that when the body is rotated to a first predetermined angle relative to the work surface, the sewage suction port of the sewage suction assembly can contact the work surface. Under the negative pressure of the sewage suction assembly, dirt on the work surface enters the sewage suction port for recovery. This effectively cleans the work surface and removes dirt, making it easy to use.

[0052] For ease of understanding, refer to Figures 1 to 7 , the specific structure and working principle of the present disclosure are explained in detail with reference to the embodiments.

[0053] refer to Figure 1 and Figure 4 In one embodiment of the present disclosure, the cleaning device includes a body 1, a floor brush assembly 2, and a dirt suction assembly 3.

[0054] The floor brush assembly 2 is rotatably connected to the housing 1, with the axis of the floor brush assembly 2 being parallel to the work surface. The floor brush assembly 2 may include a floor brush body 21 and a cleaning element 22. The housing 1 has a receiving slot 12 for mounting the floor brush body 21. The floor brush body 21 may be constructed as a cylindrical structure that fits within the receiving slot 12. The cleaning element 22 is constructed in a shape that fits within the outer edge of the floor brush body 21 and is detachably mounted on the outer circumference of the floor brush body 21.

[0055] The surface of the cleaning body 22 has bristles, and the material of the bristles can be selected according to the type of the working surface 5, such as hard bristles, velvet, etc., and there is no restriction on this. The cleaning body 22 is mounted on the floor brush body 21 in a detachable manner, for example, by means of a sleeve or an adhesive, which allows the cleaning body 22 to be replaced in a timely manner. Of course, for those skilled in the art, the cleaning body 22 and the floor brush body 21 can also be integrated and installed in a non-detachable manner, and this disclosure does not limit this.

[0056] The floor brush assembly 2 further includes a driving device disposed inside the body 1 , one end of the floor brush body 21 is in transmission connection with the output end of the driving device, and at least a portion of the surface of the cleaning body 22 is exposed from the receiving groove 12 . Figure 1In the viewing direction, the lower end of the receiving groove 12 is an open structure, and a portion of the cleaning body 22 is exposed from the lower end opening of the receiving groove 12. When the floor brush assembly 2 is performing a cleaning operation, the cleaning body 22 can contact the working surface 5, and the floor brush body 21 will be driven by the driving device to rotate around the rotation axis of the floor brush body 21 relative to the machine body 1 to clean the working surface 5.

[0057] For the convenience of description, from the user's perspective, the body 1 can be divided into a front end and a rear end. The floor brush assembly 2 is arranged at the front end of the body 1, and the rear end of the body 1 can be used as a handle of the cleaning device to facilitate the user to hold the cleaning device. The sewage suction assembly 3 is arranged on the side of the body close to the floor brush assembly 2, and the sewage suction assembly 3 and the floor brush assembly 2 face the working surface 5 together.

[0058] The dirt suction assembly 3 includes a dirt suction port 31 and a dirt suction channel 32. When the cleaning device cleans the work surface 5, the dirt suction assembly 3 draws loose dirt through the dirt suction port 31 into the dirt suction channel 32, leaving no dirt residue on the work surface 5. The dirt suction port 31 is configured to protrude from the outer edge of the body 1, ensuring sufficient contact with the work surface 5.

[0059] In one embodiment of the present disclosure, see Figure 1 The floor brush assembly 2 further includes a water spray port 23, which can be configured to spray water toward the working surface 5. After the working surface 5 is wetted by water, it can facilitate deep cleaning of the cleaning body 22. Of course, the water spray port 23 can also be configured to spray water toward the cleaning body 22. The wet cleaning body 22 can also clean the dirt on the working surface 5 during its rotation.

[0060] The water spray port 23 can be set at any position of the fuselage 1, refer to Figure 1 In the viewing direction, the water jet 23 is arranged on the fuselage 1 at the upper position or the front end position of the cleaning body 22. Of course, for those skilled in the art, the water jet 23 can also be arranged on the fuselage 1 at the rear end position of the cleaning body 22.

[0061] The above embodiments only illustrate the functions that can be achieved by the floor brush assembly and the sewage suction assembly. The shape of the floor brush body, the material of the cleaning body, the front and rear ends of the body, the setting position of the sewage suction assembly and the setting position of the water nozzle mentioned in the above embodiments need to be determined according to the specific situation and the type of work surface to be cleaned, and there is no restriction on this.

[0062] In the cleaning device disclosed in the present invention, the positional relationship between the suction port 31 and the floor brush assembly 2 is as follows: When the body 1 rotates to the first predetermined angle B relative to the working surface 5, the reference Figure 2, which enables the sewage suction port 31 to contact and cooperate with the working surface 5; the sewage suction component 3 is configured to suck in the dirt on the working surface after the sewage suction port 31 contacts and cooperates with the working surface 5.

[0063] The position of the sewage suction port 31 on the body 1 of the present invention allows the body 1 to rotate so that the floor brush assembly 2 contacts the working surface 5, while the sewage suction port 31 does not contact the working surface 5. Figure 1 The body 1 forms an initial angle A with the work surface 5. The floor brush assembly 2 is positioned on the body 1 at the front end of the sewage suction port 31. This allows the body 1 to be rotated until the floor brush assembly 2 contacts the work surface 5 while the sewage suction port 31 is not in contact with the work surface 5. In this position, the cleaning body 22 cleans the work surface 5. The water spray port 23 sprays water onto the work surface 5 or the cleaning body 22, thereby wetting the work surface 5. The force of the cleaning body 22's rotation causes reciprocating friction on the work surface 5, achieving a deep clean of the work surface 5.

[0064] After the work surface 5 is cleaned, the dirt left on the work surface 5 needs to be sucked into the cleaning device. Figure 2 The position of the sewage suction port 31 on the body 1 allows the body 1 to rotate to make the sewage suction port 31 contact the working surface 5. Since the sewage suction port 31 is set at the rear end of the floor brush assembly 2, refer to Figure 1 The viewing direction of the fuselage 1 can be pressed down at this time. For example, when the fuselage 1 is rotated from the initial angle A relative to the working surface 5 to the angle Figure 2 After reaching the first predetermined angle B shown, the sewage suction port 31 can be brought into contact with the working surface 5. At this time, the sewage suction component 3 can be opened. Under the action of negative pressure, the dirt on the working surface 5 will enter the sewage suction port 31, and eventually the sewage and / or foreign matter on the working surface 5 will be sucked into the cleaning equipment for storage.

[0065] In a specific application scenario of the present disclosure, the working surface 5 may be a carpet. When the carpet is wet and cleaned by the cleaning body 22, sewage mixed with foreign matter will penetrate into the carpet hair, making it difficult to remove the sewage using conventional cleaning equipment. The cleaning equipment of the present disclosure can fully contact the sewage suction port 31 with the carpet hair, for example, by squeezing and deforming the carpet hair, or by extending into the interior of the carpet hair, thereby removing the sewage that has penetrated into the carpet hair, improving the cleaning effect of the carpet and ensuring the dryness of the carpet.

[0066] In one embodiment of the present disclosure, when the body 1 rotates relative to the work surface 5 by a first predetermined angle B so that the suction port 31 contacts the work surface 5 , the cleaning body 22 can remain in contact with the work surface 5 or be separated from the work surface 5 .

[0067] Specifically, in one embodiment of the present disclosure, when the sewage suction port 31 contacts the work surface 5, the cleaning body 22 maintains contact with the work surface 5. In this state, both the cleaning body 22 and the sewage suction port 31 are in operation. That is, the cleaning body 22 continuously cleans the work surface 5 by rotating. During the cleaning process, the water spray port 23 can spray water onto the work surface 5 or onto the cleaning body 22 as needed. The sewage suction port 31 is located at the rear end of the cleaning body 22 and sucks in the cleaned dirt. The two work together to complete the cleaning process.

[0068] In another specific embodiment of the present disclosure, when the sewage suction port 31 contacts the work surface 5, the cleaning body 22 is separated from the work surface 5. That is, the body 1 uses the sewage suction port 31 as a support point, causing the cleaning body 22 located at the front end of the sewage suction port 31 to tilt upward, thereby separating from the work surface 5. At this time, the gravity of the middle body 1 is applied to the work surface 5 through the sewage suction port 31, which can make the sewage suction port 31 fit more closely with the work surface 5, thereby improving the suction effect of dirt on the work surface 5, such as a carpet.

[0069] In one embodiment of the present disclosure, see Figure 3 , a fulcrum 11 is provided on the body 1, and the sewage suction port 31 is located between the floor brush assembly 2 and the fulcrum 11, that is, the fulcrum 11 is provided on the body 1 at the rear end of the sewage suction port 31. This allows the body 1 to continue to rotate, and when the body 1 is further pressed down from the first predetermined angle B to the second predetermined angle C, the fulcrum 11 on the body 1 is brought into contact with the work surface. In this state, since the sewage suction port 31 is located between the floor brush assembly 2 and the fulcrum 11, by reasonably configuring the dimensions between the sewage suction port 31, the floor brush assembly 2, and the fulcrum 11, the floor brush assembly 2 is separated from the work surface 5, and the body 1 is supported on the work surface 5 only by the fulcrum 11 and the sewage suction port 31. At this time, the sewage suction assembly 3 can be opened, so that the sewage suction port 31 sucks the dirt on the work surface 5 into the sewage suction channel 32.

[0070] refer to Figure 3 In the viewing direction, with the sewage suction port 31 as a reference, the floor brush assembly 2 and the fulcrum 11 are located on either side of the sewage suction port 31, and the end of the floor brush assembly 2, the fulcrum 11, and the sewage suction port 31 that contacts the work surface 5 is marked as the bottom end. The line connecting the bottom end of the floor brush assembly 2 and the bottom end of the sewage suction port 31 forms a predetermined angle with the line connecting the bottom end of the sewage suction port 31 and the bottom end of the fulcrum 11. This ensures that when the sewage suction port 31, the fulcrum 11, and the work surface 5 all maintain contact, the floor brush assembly 2 is separated from the work surface 5.

[0071] In one embodiment of the present disclosure, the fulcrum 11 is provided on the body 1. It can be understood that the fulcrum 11 is a protrusion extending outward from the body 1, that is, the fulcrum 11 is at least a portion of the outer contour of the body 1. In order to leave space for holding the body 1, the body 1 extends outward at the position of the fulcrum 11 to form a protrusion. The protrusion can serve as the fulcrum 11 for contacting the work surface 5. In order to facilitate the reciprocating motion of the body 1 on the work surface 5, the fulcrum 11 is constructed as an arc-shaped surface, thereby reducing the contact area between the fulcrum 11 and the work surface 5, which is conducive to driving the body 1 to reciprocate on the work surface 5.

[0072] In one embodiment of the present disclosure, see Figure 3 The fulcrum 11 is a roller rotatably connected to the body 1. When the body 1 is at a second predetermined angle C relative to the working surface 5, the user holds the cleaning device and performs reciprocating motion on the working surface 5. The roller can roll relative to the working surface 5, so that the cleaning device can move smoothly on the working surface 5.

[0073] After the floor brush assembly 2 is separated from the working surface 5, it is no longer able to effectively work on the working surface 5, so it is necessary to stop the floor brush assembly 2 from working, that is, to stop the driving device that drives the floor brush body 21 to rotate. In one embodiment of the present disclosure, see Figure 3 The body 1 is provided with a sensor 4, which is configured to be triggered when the fulcrum 11 contacts the working surface 5. Accordingly, the cleaning device further includes a control unit, which controls the floor brush assembly 2 to stop working based on the electrical signal triggered by the sensor 4, so as to prevent the floor brush assembly 2 from working ineffectively. At the same time, since dirt may be attached to the floor brush assembly 2, if the cleaning body 22 of the floor brush assembly 2 continues to rotate, the dirt may be thrown out and cause secondary pollution. Therefore, stopping the operation of the floor brush assembly 2 can also effectively prevent further pollution.

[0074] In another embodiment of the present disclosure, see Figure 3 When the body 1 is pressed down so that the fulcrum 11 contacts the working surface 5 and triggers the sensor 4, the sewage suction port 31 remains in contact with the working surface 5. Based on this, the control unit can control the sewage suction component 3 to generate suction based on the electrical signal triggered by the sensor 4 to suck in the dirt on the working surface.

[0075] When the cleaning device of the present disclosure is working, the body 1 can be held by hand so that the floor brush assembly 2 keeps in contact with the working surface 5, and the sewage suction port 31 and the fulcrum 11 are separated from the working surface 5. Figure 1As shown, the body 1 and the work surface 5 form an initial angle A. In this state, the user can hold the body 1 and move it back and forth on the work surface 5 so that the rotating floor brush assembly 2 cleans the work surface 5. During the cleaning process, the water spray port 23 can spray water onto the work surface 5 or the cleaning body 22 of the floor brush assembly 2, thereby completing the cleaning of the work surface 5.

[0076] See also Figure 2 When the cleaning phase of the work surface 5 is finished, the user can press down the body 1 and rotate it to the first predetermined angle B, so that the sewage suction port 31 at the rear end of the floor brush assembly 2 contacts the work surface 5, and the user will feel that the sewage suction port 31 contacts the work surface 5. At this time, see Figure 3 The user can continue to press down on the body 1 and rotate it to the second predetermined angle C, so that the fulcrum 11 at the rear end of the sewage suction port 31 contacts the work surface 5, and the user will feel the contact between the fulcrum 11 and the work surface 5. In this state, the floor brush assembly 2 will be separated from the work surface 5. When the fulcrum 11 contacts the work surface 5, the sensor 4 is triggered. Based on the electrical signal triggered by the sensor 4, the control unit controls the floor brush assembly 2 to stop rotating and controls the sewage suction assembly 3 to open, so that the dirt left on the work surface 5 will be sucked into the sewage suction port 31, completing the cleaning of the work surface 5.

[0077] In one embodiment of the present disclosure, when the floor brush assembly 2 cleans the work surface 5, the dirt suction assembly 3 is configured to be turned on at the same time to suck in some of the dirt on the work surface 5 through the dirt suction port 31. In this state, the control unit can control the dirt suction assembly 3 to operate at a first power. When the lower body 1 rotates to a second predetermined angle, the fulcrum 11 contacts the work surface 5, the sensor 4 is triggered, and the control unit receives a signal from the sensor 4 to control the dirt suction assembly 3 to operate at a second power. The second power can be greater than or less than the first power, and is selected according to the specific application scenario. For example, when the fulcrum 11 and the dirt suction port 31 contact the work surface 5 and the floor brush assembly 2 is separated from the work surface 5, the dirt suction assembly 3 is controlled to operate at a higher power so that the dirt suction port 31 has a greater suction force to suck away most of the dirt on the work surface 5 until the dirt on the work surface 5 is completely removed.

[0078] In order to realize the function of the sensor 4 in the above embodiment, the sensor 4 can be a pressure sensor, a photoelectric sensor, a displacement sensor or a Hall sensor, etc., which can be triggered by touch or position change, so that the body 1 is rotated from the first predetermined angle to the second predetermined angle relative to the first predetermined angle, so that the fulcrum 11 contacts the working surface 5, and the sensor 4 is triggered, and then the control unit controls the floor brush assembly 2 and the dirt suction assembly 3 based on the signal of the sensor 4. The above sensor forms are only examples.

[0079] For example, in the embodiment of the present disclosure in which the fulcrum 11 is a roller, the roller is not only rotatably connected to the body 1 but is also configured to be displaceable relative to the body 1, for example, to move into the body 1. When the roller contacts the working surface 5, the gravity of the body 1 causes the roller to move into the body 1, thereby triggering the sensor 4. When the roller is released from the working surface 5, the elastic device causes the roller to return to its original position.

[0080] In one embodiment of the present disclosure, the elastic device is a spring 13 and the sensor 4 is a micro switch. Figure 3 and Figure 5 The roller is connected to the body 1 via a spring 13, and a space for the roller to move is provided on the body 1. For example, the roller can be rotatably connected to a roller seat, which is in turn guided and fitted on the body 1, so that the roller can squeeze the spring 13 to move into the body 1, or the roller can be reset under the action of the spring 13.

[0081] refer to Figure 1 、 Figure 2 When the body 1 is at the initial angle A and the first predetermined angle B, in this state, the roller is not in contact with the working surface 5. At this time, the roller is in the initial position under the elastic force of the spring 13, and the micro switch is in the closed state.

[0082] refer to Figure 3 When the body 1 is at the second predetermined angle C, the floor brush assembly 2 is separated from the ground, and the sewage suction port 31 and the roller are in contact with the working surface 5. Under the pressure of the working surface 5, the roller moves into the body 1 and squeezes the spring 13. At this time, the roller can move to trigger the micro switch, so that the control unit can send a corresponding control signal based on the electrical signal triggered by the micro switch, such as controlling the sewage suction component to generate suction to suck in the dirt on the working surface, or controlling the sewage suction component 3 to work at the second power to suck in the dirt on the working surface. In addition to cleaning the rigid working surface 5, the cleaning device disclosed in the present invention can also clean flexible working surfaces, such as sofas, car seats, carpets, etc. However, when processing the flexible working surface, the sewage suction port 31 may not be able to completely suck in the dirt on the flexible working surface or the water in which the flexible working surface 5 is immersed due to deformation of the flexible working surface or immersion of the flexible working surface in water. To address the above problem, the sewage suction port 31 can have an interference fit with the work surface 5 at the first predetermined angle B, so that the sewage suction port 31 can be tightly attached to the work surface 5. When cleaning the flexible work surface, the sewage suction port 31 can suck dirt on the flexible work surface or water immersed in the flexible work surface into the sewage suction channel 32, thereby improving the sewage suction effect of the sewage suction port 31.

[0083] See also Figure 3 At the second predetermined angle C, the sewage suction port 31 can still be interference-fitted with the working surface 5. Figure 2Unlike the first predetermined angle B shown, at the first predetermined angle B, a first interference fit can exist between the sewage suction port 31 and the work surface 5; at the second predetermined angle C, a second interference fit can exist between the sewage suction port 31 and the work surface 5. The second interference fit is greater than the first interference fit. In other words, at the second predetermined angle C, the sewage suction port 31 is pressed tightly against the work surface 5. For example, if the work surface 5 is carpeted, the sewage suction port 31 can squeeze the carpet, causing a certain degree of deformation, thereby compacting the carpet and improving the sewage suction effect of the sewage suction port 31.

[0084] When the cleaning equipment cleans the flexible working surface, a greater negative pressure is formed between the suction port 31 and the working surface 5, which sucks the dirt on the flexible working surface or the water immersed in the flexible working surface into the suction channel 32, thereby improving the suction effect of the suction port 31.

[0085] exist Figure 3 In the illustrated embodiment, the sewage suction channel 32 is configured to be inclined from the main body 1 toward the floor brush assembly 2 or toward the fulcrum 11. This structural design reduces the movement resistance of the sewage suction port 31 on the work surface 5 when the main body 1 rotates until the fulcrum 11 contacts the work surface 5, thereby pushing the main body 1 to move on the work surface 5. In addition, the sewage suction effect of the sewage suction port 31 can be improved.

[0086] In one embodiment of the present disclosure, see Figure 6 The body 1 can be connected to the main unit 6 through a pipe 7 for use. The structure and functions of the body 1 are the same as those described in the above embodiment. In this embodiment, the power, negative pressure, water, etc. required to achieve the above functions can all be provided to the body 1 by the main unit 6. Therefore, the cleaning device disclosed in the present invention can be used as a standalone cleaning device or used in conjunction with the main unit 6.

[0087] Continue to see Figure 6 When in use, the user needs to start the host 6 first, and then can hold the body 1 to achieve cleaning at various angles on the work surface. For example, when the user needs to wash the work surface 5, the user can hold the body 1 to make the floor brush assembly 2 contact with the work surface 5 to clean the work surface 5, which is convenient and quick.

[0088] See also Figure 7 The present disclosure further provides a working method of a cleaning device, which is applied to the cleaning device provided in any of the above embodiments, and the method includes:

[0089] S100: Control the cleaning device to move across the work surface 5, causing the floor brush assembly 2 to clean the work surface 5. In this step, the body 1 is rotated until the floor brush assembly 2 contacts the work surface 5, disengaging the suction port 31 from the work surface 5. In this state, the body 1 is moved back and forth across the work surface 5. During movement, the floor brush assembly 2 cleans the work surface 5 through its rotation. Water can also be sprayed onto the work surface 5 or the cleaning body 22 of the floor brush assembly 2 through the water spray port 23, thereby completing the cleaning of the work surface 5.

[0090] S200: The cleaning device body is controlled to rotate toward the work surface 5 by a first predetermined angle, so that the suction port of the suction assembly contacts and engages with the work surface 5. In this step, since the suction port 31 is provided at the rear end of the floor brush assembly 2, the body 1 can be pressed downward to rotate until the suction port 31 contacts the work surface 5.

[0091] In the embodiment of the present disclosure where the body 1 further includes a fulcrum 11, the body 1 can be pressed down from a first predetermined angle to a second predetermined angle so that the fulcrum 11 contacts the working surface 5. In this state, the sewage suction port 31 continues to maintain contact with the working surface 5, and the floor brush assembly 2 is disengaged from the working surface 5.

[0092] S300: Control the suction assembly 3 so that the suction port 31 draws dirt from the work surface 5. Once the suction port 31 contacts the work surface 5, it can be opened to draw dirt from the work surface 5. In this step, the opening of the suction port 31 can be controlled by the sensor 4. For example, when the body rotates so that the suction port 31 contacts the work surface 5, the sensor 4 is triggered, causing the floor brush assembly 2 to stop and the suction assembly 3 to operate, drawing dirt from the work surface through the suction port 31.

[0093] In the embodiment of the present disclosure in which the body 1 includes a fulcrum 11, when the fulcrum 11 contacts the work surface 5, the sensor 4 is triggered, and the control unit can control the floor brush assembly 2 to stop and the sewage suction assembly 3 to start based on the electrical signal triggered by the sensor 4, so as to suck the dirt on the work surface through the sewage suction port 31.

[0094] The details of this method have been described in detail in the above embodiments in conjunction with the usage scenarios and will not be repeated here.

[0095] Use scenario 1

[0096] The main body 1 is controlled to rotate until the floor brush assembly 2 contacts the carpet, disengaging the suction port 31 from the carpet. In this state, the main body 1 is pushed back and forth across the carpet, and the floor brush assembly 2 cleans the carpet through its own rotation during movement. Water can also be sprayed through the water spray port 23 onto the carpet or the cleaning body 22 of the floor brush assembly 2, thereby completing the cleaning of the working surface 5.

[0097] After the cleaning step is complete, the cleaning device's main body is controlled to rotate toward the carpet by a first predetermined angle, bringing the suction port 31 of the suction assembly into contact with the carpet. In this step, since the suction port 31 is located at the rear end of the floor brush assembly 2, the main body 1 is pressed downward to rotate until the suction port 31 contacts the carpet. At this point, the suction assembly 3 is controlled to cause the suction port 31 to draw in dirt from the work surface 5.

[0098] Use Scenario 2

[0099] The main body 1 is controlled to rotate until the floor brush assembly 2 contacts the sofa, disengaging the suction port 31 from the sofa. In this state, the main body 1 is pushed back and forth over the sofa, and the floor brush assembly 2 cleans the sofa through its own rotation during movement. Water can also be sprayed through the water spray port 23 onto the sofa or the cleaning body 22 of the floor brush assembly 2 to complete the cleaning of the sofa.

[0100] After the cleaning process is complete, the cleaning device's body 1 is controlled to rotate toward the sofa by a first predetermined angle, causing the suction port 31 of the suction assembly 3 to contact and mate with the sofa. The body 1 is then pressed downward to rotate from the first predetermined angle to a second predetermined angle, causing the fulcrum 11 on the body 1 to contact the sofa. At this point, the floor brush assembly 2 disengages from the sofa, while the suction port 31 maintains contact with the sofa. When the fulcrum 11 contacts the sofa, the sensor 4 is triggered. Based on the trigger signal from sensor 4, the control unit controls the floor brush assembly 2 to stop and the suction assembly 3 to open, thereby sucking in dirt from the sofa through the suction port 31. Under the action of gravity on the body 1, the fulcrum 11, the suction port 31, and the sofa form an interference fit, squeezing and deforming the sofa. In this state, the suction port 31 can suck out any water stains that have penetrated the sofa, thereby ensuring a clean sofa.
