[0062] According to an embodiment of the present disclosure, a cleaning system is provided. Figure 1 A schematic diagram showing an embodiment of the cleaning system.

[0063] As Figure 1 shown, the cleaning system 10 may include a base station 100 and a surface cleaning device 200.

[0064] The base station 100 can be used for the surface cleaning device 200 to dock. After the surface cleaning device 200 docks to the base station 100, the base station 100 can be activated to at least self-clean the roller brush of the surface cleaning device 200 and dry the roller brush after self-cleaning. In addition, the base station 100 can also communicate with the surface cleaning device 200 for information interaction and / or control of the surface cleaning device 200, etc. Of course, charging of the surface cleaning device 200, replenishment of cleaning liquid, etc. can also be achieved through the base station 100.

[0065] The surface cleaning device 200 can be operated by a user to clean a surface to be cleaned such as a floor. In the present disclosure, the surface cleaning device 200 can achieve wet cleaning of the surface to be cleaned during the cleaning process, that is, it can provide a cleaning liquid to the surface to be cleaned and recycle and store the used cleaning liquid.

[0066] The following will refer to Figure 2 for a detailed description of the structure of the surface cleaning device 200. As Figure 2 shown, the surface cleaning device 200 may include a main body portion 210, a base portion 220, and a grip portion 230

[0067] The main body portion 210 can be used to configure the liquid supply portion 211 and the liquid recovery portion 212. The liquid supply portion 211 can be used to hold a cleaning liquid, which can be cleaning water, a mixed liquid of cleaning water or a cleaning agent, etc. The user can remove the liquid supply portion 211 from the main body portion 210 to replenish the cleaning liquid. Additionally, when the surface cleaning device 200 docks to the base station 100, the base station 100 can also be used to replenish the cleaning liquid for the liquid supply portion 211 of the surface cleaning device 200. The cleaning liquid can be provided from the liquid supply portion 211 to the base portion 220 through internal pipelines provided in the main body portion 210 and the base portion 220. During the process that the rotary brush 221 rolls on the surface to be cleaned for cleaning it, the cleaning liquid is also provided to the surface to be cleaned, so that the rotary brush 221 can perform wet cleaning on the surface to be cleaned through the cleaning liquid.

[0068] The liquid recovery portion 212 can suck the cleaned cleaning liquid as the recovered liquid through a suction nozzle disposed near the rotary brush 221, and the recovered liquid is stored in the liquid recovery portion 212 through internal pipelines provided in the main body portion 210 and the base portion 220. The user can remove the liquid recovery portion 212 from the main body portion 210 to pour out the recovered liquid in the liquid recovery portion 212.

[0069] In Figure 2 Although it is shown in that the liquid supply portion 211 and the liquid recovery portion 212 are arranged on one side of the main body portion 210 and arranged vertically, the liquid supply portion 211 and the liquid recovery portion 212 can also be arranged on two opposite sides of the main body portion 210 (front - rear arrangement, left - right arrangement). In addition, it can also be arranged in a form where the liquid supply portion 211 is at the lower part and the liquid recovery portion 212 is at the upper part.

[0070] In the present disclosure, a first - type detection device can also be provided at a corresponding position of the main body portion 210. The first - type detection device can be used to detect whether the liquid recovery portion 212 is in place (whether it is correctly installed on the main body portion), and can also detect whether the liquid recovery portion 212 is full, that is, whether it reaches a liquid level threshold. The first - type detection device can include multiple detection devices, such as an in - place detection device and a liquid level detection device, etc. For example, it can be determined whether the liquid recovery portion 212 is reinstalled on the main body portion 210 after being removed from the main body portion 210 to pour out the recovered liquid. The first - type detection device can be in the form of electrical contacts, or can also be in the form of various detection devices in the prior art such as photoelectric sensors and Hall sensors. In addition, a second - type detection device can also be provided at a corresponding position of the main body portion 210. The second - type detection device can be used to detect whether the liquid supply portion 211 is in place. The second - type detection device can be in the form of electrical contacts, or can also be in the form of various detection devices in the prior art such as photoelectric sensors and Hall sensors.

[0071] In addition, a display unit 213 may be provided in the main body 210. The display unit 213 can be used to display the working state of the surface cleaning device 200, can also receive user input instructions to control the surface cleaning device 200, and can also display the interaction state with the base station 100 and so on.

[0072] The base 220 may be configured with a roller brush 221. The roller brush 221 rolls relative to the surface to be cleaned so as to cooperate with the cleaning liquid to perform wet cleaning on the surface to be cleaned as described above. The main body 210 may be rotatably connected to the base 220.

[0073] The holding part 230 is fixedly connected to the main body 210 for the user to hold. In this way, during the cleaning process by the user, the user can control the entire surface cleaning device 200 by controlling the holding part 230. Corresponding buttons may be provided on the holding part 230, and the user can control the corresponding functions of the surface cleaning device 200 by controlling the corresponding buttons.

[0074] It should be noted that the surface cleaning device 200 described in this application is only exemplarily illustrated, and other types of surface cleaning devices 200 may also be applicable to this disclosure as long as they include a liquid supply part and a liquid recovery part.

[0075] Figure 3 A schematic diagram of a base station according to an embodiment of the present disclosure is shown. It should be noted that this base station is only schematic, and other forms of base stations may also be adopted in this disclosure.

[0076] As Figure 3 shown, the base station 100 may include a tray 110. The tray 110 can be used to support the base 220 of the surface cleaning device 200. A cleaning part 111 is provided at a position corresponding to the roller brush on the tray 110. After the surface cleaning device is placed on the base station 100, the roller brush 221 can be received in the cleaning part 111. In addition, correspondingly to the roller brush 221, an air outlet part 120 may also be provided on the tray 110. The air outlet part 120 can be used to provide gas for drying so as to dry the roller brush 221. The drying gas can be provided from the inside of the base station 100 to the roller brush 221 via the air outlet part 120.

[0077] After the surface cleaning device 200 is correctly placed on the base station 100, the surface cleaning device 200 can be charged by the base station 100 and can communicate with the base station 100. The self-cleaning process of the roller brush of the surface cleaning device 200 can be carried out by user control or automatic control, and the control method can adopt the existing method. During the self-cleaning process, the cleaning liquid can be provided to the roller brush 221 through the liquid supply part 211 of the surface cleaning device 200, and the cleaning of the roller brush 221 is realized by the rotation of the roller brush 221. In addition, after the self-cleaning process is completed, the drying gas can be provided to the roller brush 221 through the air outlet part 120 to dry it. This drying process can be carried out automatically after the self-cleaning process or manually according to the user's control. When carrying out the self-cleaning process, the first type of detection device can be used to detect whether the liquid recovery part 212 is in place and full. If the liquid recovery part 212 is not in place or full, the self-cleaning process is not carried out, but the user can be prompted to put back the liquid recovery part 212. Only when the liquid recovery part 212 is placed in place and not in a full state, the self-cleaning process is allowed. However, if the roller brush 221 is in a drying state, it is not necessary to detect whether the liquid recovery part 212 is in place and full by the first type of detection device. That is, regardless of whether the liquid recovery part 212 is in place and full, the drying process can be carried out. The detection and signal processing of the first type of detection device can adopt the relevant content in the prior art.

[0078] Figure 4 A partial cross-sectional view of the base station is shown. As Figure 4 shown, a drying device can be provided in the base station 100, which can include a gas generation part 130 such as a blower and a heating body 140. The gas generation part 130 can generate an air flow (as shown by the arrow), and the air flow can be heated by the heating body 140 to become a drying gas. The drying gas is then provided outward through the air outlet part 120. The heating body 140 can be a PTC (Positive Temperature Coefficient) heater. The heating body 140 can be arranged near the gas generation part 130, in the air flow duct, or in the air outlet part 120, etc. In the present disclosure, the air flow duct can be formed by the housing 150 of the air duct below the tray 110, and the air flow duct can be in fluid communication with the gas generation part 130 and the air outlet part 120.

[0079] In addition, a cleaning liquid supply unit 160 may be configured on the base station 100. The cleaning liquid supply unit 160 contains cleaning liquid, and after the surface cleaning device 200 is in waterway communication with the base station 100, the cleaning liquid stored in the cleaning liquid supply unit 160 of the base station 100 can be supplied to the liquid supply unit 211 of the surface cleaning device 200 through control.

[0080] As described above, when the liquid recovery unit 212 is detected as not in place or full, the self-cleaning process is not performed or the self-cleaning process is interrupted. Whether the liquid recovery unit 212 is in place or full, the drying process is performed. That is, during the drying process, detection by the first type of detection device may not be required. When self-cleaning is required, it is determined whether the liquid recovery unit of the surface cleaning device is in place and / or whether the liquid in the liquid recovery unit has not reached the liquid level threshold. If so, the surface cleaning device and / or the base station are started to perform self-cleaning on the roller brush of the surface cleaning device. If not, the surface cleaning device and / or the base station are prohibited from performing self-cleaning on the surface cleaning device. When drying is required, regardless of whether the liquid recovery unit of the surface cleaning device is in place and / or whether the liquid in the liquid recovery unit has reached the liquid level threshold, the drying device of the base station is started to dry the surface cleaning device.

[0081] The following will describe each situation in detail. For example, the user can control the surface cleaning device to enter the self-cleaning mode through mobile terminal control, through the buttons on the base station, or through the buttons on the surface cleaning device. If the surface cleaning device is about to enter the self-cleaning process, it is first necessary to obtain the detection signal of the first type of detection device. If the liquid recovery unit is not in place or full, the self-cleaning process is not started, but the user is prompted to put the liquid recovery unit back or is prompted that the liquid recovery unit is full. Only when the liquid recovery unit is in place and not full will the self-cleaning process be entered to self-clean the roller brush. If the surface cleaning device is performing the self-cleaning process and it is detected by the first type of detection device that the liquid recovery unit is not in place (the user removes the liquid recovery unit during the self-cleaning process) or full, the self-cleaning process is paused, and the user is prompted to put the liquid recovery unit back or is prompted that the liquid recovery unit is full. After the liquid recovery unit is dumped and put back in place, the self-cleaning process continues. After the self-cleaning process ends, the user can also be prompted to clean the liquid recovery unit.

[0082] After the self-cleaning process is completed, the drying process can be carried out by the user controlling through a mobile terminal, controlling through a button on the base station, or controlling through a button on the surface cleaning device. Of course, after the self-cleaning process, the drying process can also be carried out automatically. For example, the self-cleaning mode can include two processes: self-cleaning and drying. During the drying process, the gas generation unit 130 and the heating element 140 of the base station are started, and drying gas is provided to the roller brush 221 through the air outlet 120.

[0083] In the case of entering the drying process through the control method, the drying process is carried out regardless of whether the liquid recovery unit is removed by the user. In addition, regardless of whether the liquid recovery unit is full, the drying process is carried out. In the case of automatic drying, after the self-cleaning process is completed, the surface cleaning device can notify the base station. After successful communication, the base station is started to provide drying gas to the roller brush, and the surface cleaning device can make the roller brush rotate at a certain speed to fully dry the roller brush.

[0084] According to an example of the present disclosure, the surface cleaning device may include a control unit that can at least receive instructions from the user. Various above-mentioned processes / operations can be carried out according to the instructions of the user.

[0085] In addition, although the liquid recovery unit can be removed for cleaning during the drying process, the user can also be prompted to put back the liquid recovery unit by voice or other means, but the drying process will not be interrupted. In addition, when the surface cleaning device is in the standby or charging state, if it is detected that the liquid recovery unit is not in place, the user can also be prompted to put back the liquid recovery unit at this time, or if the liquid recovery unit is full, the user can also be prompted to clean the liquid recovery unit. When the liquid recovery unit is not in place or full, it can be controlled that even if the user presses the self-cleaning button or other working buttons, the corresponding process will not be carried out. However, if a corresponding button is separately set for the drying process, if the drying button is pressed, the drying process can be carried out. In addition, in order to prevent the user from forgetting to clean the liquid recovery unit, the user can also be prompted to clean the liquid recovery unit during the drying process or other processes to prevent bacteria and the like from growing in the liquid recovery unit.

[0086] The cleaning system provided by the present disclosure can perform a drying process after the surface cleaning device self-cleans the roller brush, allowing the user to clean the liquid recovery part while the drying process is in progress. In this way, after the self-cleaning process is completed, the liquid recovery part can be cleaned in a timely manner, avoiding the growth of bacteria and the generation of odors. Additionally, by allowing the liquid recovery part to be processed while the drying process is in progress, the user does not need to wait until the long drying process is completed before cleaning the liquid recovery part, and will not forget to clean the liquid recovery part due to long waiting times. The solution according to the present disclosure can well improve the user experience and also extend the service life of the surface cleaning device, etc.

[0087] According to a further embodiment of the present disclosure, a self-cleaning method for a cleaning system is also provided. Among them, the relevant descriptions of the cleaning system above can all be applied to the self-cleaning method of the present disclosure, and will not be repeated here for the sake of brevity.

[0088] Figure 5 A flowchart showing the self-cleaning method according to an embodiment of the present disclosure is shown. As Figure 5 shown, the self-cleaning method S500 may include the following steps. In Figure 5 the illustrated embodiment, both the self-cleaning process and the drying process can be set in the self-cleaning mode, that is, when entering the self-cleaning mode, the self-cleaning process can be performed first, and after the self-cleaning process is completed, the drying process can be performed.

[0089] In step S502, a start signal is generated, where the start signal is used to control the surface cleaning device to start the self-cleaning mode. The start signal can be formed according to a user instruction. For example, when the user presses the "self-clean" button on the holding part of the surface cleaning device or enters a relevant instruction on the display part of the surface cleaning device, or when the user clicks the "self-clean" button on a mobile terminal associated with the cleaning system, a user instruction can be generated. For example, the control unit of the surface cleaning device can generate a start signal based on the above user instructions. Additionally, the start signal can also be automatically formed. For example, when the surface cleaning device is placed in the base station, the start signal can be automatically generated according to actual conditions to start the self-cleaning mode of the surface cleaning device.

[0090] In step S504, a detection signal of a first type of detection device is received, where the detection signal at least includes an in-position detection signal indicating whether the liquid recovery part is in position and a liquid level detection signal indicating whether the liquid recovery part has reached the liquid level threshold (full). In the case where the liquid recovery part is not in position or is full, the process proceeds to step S506. In the case where the liquid recovery part is in position and not full, the process proceeds to step S508.

[0091] In step S506, if it is determined based on the in-position detection signal that the liquid recovery unit is not properly placed on the main body unit, the user is prompted to place the liquid recovery unit back; if it is determined based on the liquid level detection signal that the liquid recovery unit is full, the user is prompted to clean the liquid recovery unit. And the in-position detection signal and the liquid level detection signal can be continuously received.

[0092] In step S508, a self-cleaning process is performed. During the self-cleaning process, the surface cleaning device rotates the roller brush at a certain speed and supplies the cleaning liquid from the liquid supply unit near the roller brush to clean the roller brush.

[0093] After the self-cleaning process of the roller brush in step S508 is completed, a self-cleaning end signal can be generated and the self-cleaning process can be stopped. Then, step S510 can be entered to perform the drying process. At this time, the surface cleaning device can generate a drying signal, and this drying signal can be sent to the base station. The base station can start the drying device according to the received drying signal, and the surface cleaning device makes the roller brush roll. After the drying process is completed, step S512 can be executed to exit the self-cleaning mode.

[0094] Optionally, during the self-cleaning process, the detection signals of the first type of detection device can be continuously obtained. For example, in step S514, the in-position detection signal and the liquid level detection signal can be received, and when the liquid recovery unit is not in position or full, step S516 is entered. When the liquid recovery unit is in position and not full, step S508 continues.

[0095] In addition, according to an optional embodiment of the present disclosure, during the self-cleaning process, the liquid recovery unit can be locked to the main body unit to prevent the user from removing the liquid recovery unit. In this case, only the liquid level detection signal can be received, and when the liquid recovery unit is full, step S516 is entered.

[0096] In step S516, the self-cleaning process can be aborted. For example, the surface cleaning device can generate an abort signal and abort the self-cleaning process according to the abort signal. In step S518, the user can be prompted to place the liquid recovery unit back or clean the liquid recovery unit. When only the liquid level detection signal is received in step S514, the user can be prompted to clean the liquid recovery unit when the liquid recovery unit is full. And the situation of the liquid recovery unit is continuously detected, and when the liquid recovery unit is in position and not full, step S508 continues.

[0097] Additionally, according to an alternative embodiment, even during the drying process of the rotatable brush, in-position detection signals and liquid level detection signals can be received. When it is determined based on the in-position detection signal that the liquid recovery unit is not properly installed in the main body unit, the user can be prompted to place the liquid recovery unit back. When it is determined based on the liquid level detection signal that the liquid recovery unit is full, the user can be prompted to clean the liquid recovery unit. According to a preferred embodiment of the present disclosure, after the rotatable brush completes the self-cleaning process, the user can be prompted to clean the liquid recovery unit regardless of whether the liquid recovery unit is full, so as to prevent bacteria growth caused by the user forgetting to clean the liquid recovery unit.

[0098] In the present disclosure, after entering the self-cleaning mode, the rotatable brush is self-cleaned with cleaning liquid. During the self-cleaning process, it can continuously detect whether the liquid recovery unit is in position or full. If the liquid recovery unit is removed by the user and not in position, the self-cleaning process is aborted. If the liquid recovery unit reaches the liquid level threshold, the self-cleaning process is also aborted. After the self-cleaning process is completed, the drying process can be automatically entered. During the drying process, regardless of whether the liquid recovery unit is in position and / or reaches the liquid level threshold, the drying process will not be interrupted. That is to say, during the drying process, the user can remove the liquid recovery unit for cleaning. At the same time, during the drying process, the user can also be reminded to clean the liquid recovery unit, place the liquid recovery unit back, etc., but the drying process will not be interrupted.

[0099] In Figure 5 the embodiment of, a method of setting both the self-cleaning process and the drying process in the self-cleaning mode is described. However, according to a further embodiment of the present disclosure, the user can also be allowed to separately start the self-cleaning process and the drying process by inputting different instructions. For example, a "self-clean" button and a "dry" button can be provided on the touch screen of the surface cleaning device, a "self-clean" button and a "dry" button can be provided on the holding part of the surface cleaning device, and a "self-clean" button and a "dry" button can be provided in the corresponding control software of the mobile terminal.

[0100] Figure 6 FIG. shows a self-cleaning method of a cleaning system according to an embodiment of the present disclosure. Among them, the above descriptions related to the cleaning system can all be applied to the self-cleaning method S600 of the present disclosure, and the self-cleaning method S600 can at least include the following content.

[0101] In step S602, a self-cleaning process is started. The start of the self-cleaning process can be formed according to a user instruction. For example, when the user presses the "Self-Cleaning" button on the gripping part of the surface cleaning device or inputs a relevant instruction on the display part of the surface cleaning device, or when the user clicks the "Self-Cleaning" button on a mobile terminal associated with the cleaning system, a user instruction can be generated. The control unit of the surface cleaning device can generate a start signal for the self-cleaning process based on the above user instruction. Additionally, the self-cleaning process can also be automatically started. For example, after the surface cleaning device is placed on the base station, the self-cleaning process of the surface cleaning device can be automatically started according to actual conditions.

[0102] After starting the self-cleaning process in step S602, relevant conditions for the self-cleaning process need to be judged. In step S604, it is at least necessary to judge whether the liquid recovery part is in place and whether the liquid recovery part has reached the liquid level threshold (full). In this step, the detection signal of the first type detection device can be received to judge whether the predetermined condition is met, where the detection signal at least includes an in-place detection signal indicating whether the liquid recovery part is in place and a liquid level detection signal indicating whether the liquid recovery part has reached the liquid level threshold (full). If the predetermined condition is not met, the self-cleaning process is not performed. For example, if the liquid recovery part is not in place or full, it will transfer to step S606; if the liquid recovery part is in place and not full, it will transfer to step S608.

[0103] In step S606, if it is judged according to the in-place detection signal that the liquid recovery part is not correctly placed on the main body part, the user is prompted to place the liquid recovery part back; if it is judged according to the liquid level detection signal that the liquid recovery part is full, the user is prompted to clean the liquid recovery part.

[0104] In step S608, the self-cleaning process is performed. During the self-cleaning process, the surface cleaning device rotates the roller brush at a certain speed and provides the cleaning liquid from the liquid supply part near the roller brush to clean the roller brush.

[0105] During the self-cleaning process, the detection signals of the first type detection device can be continuously obtained, and the in-place detection signal and the liquid level detection signal can be received. For example, in step S610, the in-place detection signal and the liquid level detection signal can be received, and if the liquid recovery part is not in place or full, it will transfer to step S612. If the liquid recovery part is in place and not full, step S608 will continue.

[0106] In addition, according to an optional embodiment of the present disclosure, during the self-cleaning process, the liquid recovery part can be locked onto the main body part to prevent the user from removing the liquid recovery part. In this case, only the liquid level detection signal can be received. When the liquid recovery part is full, the process proceeds to step S612.

[0107] In step S612, the self-cleaning process can be aborted. For example, the surface cleaning device can generate an abort signal and abort the self-cleaning process according to the abort signal. In step S614, the user can be prompted to replace the liquid recovery part or clean the liquid recovery part. When only the liquid level detection signal is received in step S610, the user can be prompted to clean the liquid recovery part when the liquid recovery part is full. And the situation of the liquid recovery part can be continuously detected. When the liquid recovery part is in place and not full, the process continues with step S608.

[0108] In step S616, it can be determined that the self-cleaning process is complete. The determination of the completion of the self-cleaning process can be achieved according to a set time. For example, after the self-cleaning process for the set time, it can be considered that the self-cleaning process is complete. Additionally, it can also be achieved according to the cleanliness of the roller brush. For example, by detecting the cleanliness of the roller brush, when a certain cleanliness level is reached, it can be considered that the self-cleaning process is complete. Those skilled in the art can also adopt other methods to determine the completion of the self-cleaning process.

[0109] When it is determined in step S616 that the self-cleaning process is complete, step S618 can be executed to perform a drying process. The start of the drying process can be completed according to a user instruction. For example, when the user presses the "dry" button on the grip part of the surface cleaning device or enters a drying-related instruction on the display part of the surface cleaning device, or when the user clicks the "dry" button on a mobile terminal associated with the cleaning system, a user instruction can be generated. The control unit of the surface cleaning device can generate a start signal for the self-cleaning process based on the above user instruction. Additionally, the self-cleaning process can also be automatically started. For example, when the self-cleaning process is complete, it can automatically enter the drying process according to the processing flow. During this process, for example, the surface cleaning device can generate a drying signal, and the drying signal can be sent to the base station. The base station can start the drying device according to the received drying signal, and the surface cleaning device causes the roller brush to rotate.

[0110] In addition, during the drying process, step S620 can be performed simultaneously. In step S620, it can be detected by the first type of detection device whether the liquid recovery part is in place. Thus, when it is determined according to the detected in-place detection signal that the liquid recovery part is not placed in the appropriate position, the user can be reminded to replace the liquid recovery part. Additionally, the user can also be reminded to clean the liquid recovery part. For example, the user can be reminded to clean the liquid recovery part after the self-cleaning process is complete.

[0111] In the present disclosure, after entering the self-cleaning process, the roller brush is self-cleaned by the cleaning liquid. During the self-cleaning process, it is possible to continuously detect whether the liquid recovery part is in place or full. If the liquid recovery part is removed by the user and not in place, the self-cleaning process is aborted. If the liquid in the liquid recovery part reaches the liquid level threshold, the self-cleaning process is also aborted. After the self-cleaning process is completed, the drying process can be automatically entered. During the drying process, regardless of whether the liquid recovery part is in place and / or whether it reaches the liquid level threshold, the drying process will not be interrupted. That is to say, during the drying process, the user can remove the liquid recovery part for cleaning. At the same time, during the drying process, the user can also be reminded to clean the liquid recovery part, put the liquid recovery part back, etc., but the drying process will not be interrupted.

[0112] The cleaning method of the present disclosure will be further described below, and the content described below can be incorporated into the corresponding embodiments above. The cleaning method can determine whether self-cleaning is required. When self-cleaning is required, it can be determined whether the liquid recovery part of the surface cleaning device is in place and / or whether the liquid in the liquid recovery part has not reached the liquid level threshold; if so, the cleaning device and / or the base station are started to perform self-cleaning on the surface cleaning device; if not, the cleaning device and / or the base station are prohibited from performing self-cleaning on the surface cleaning device; when drying is required, regardless of whether the liquid recovery part of the cleaning device is in place and / or whether the liquid in the liquid recovery part has reached the liquid level threshold, the cleaning device and / or the base station are started to perform drying on the surface cleaning device.

[0113] Determining whether the liquid recovery part of the cleaning device is in place may include: detecting whether the liquid recovery part is in place by an in-place detection device provided on the main body of the cleaning device.

[0114] Determining whether the liquid in the liquid recovery part has reached the liquid level threshold may include: detecting whether the liquid in the liquid recovery part has reached the liquid level threshold by a liquid detection device provided on the liquid recovery part.

[0115] The cleaning method can perform cleaning through the first cleaning mode (self-cleaning process + drying process) or the second cleaning mode (drying process). The first cleaning mode can include: the control unit generates a first control signal, and the surface cleaning device performs a self-cleaning process on the roller brush. After the self-cleaning process is completed, the control unit generates a second control signal, and the surface cleaning device ends the self-cleaning process of the roller brush. The control unit generates a third control signal and sends the third control signal to the base station. The base station receives the third control signal and starts the drying process of the roller brush by the base station. The second self-cleaning mode can include: the control unit generates a third control signal and sends the third control signal to the base station. The base station receives the third control signal and starts the drying process of the roller brush by the base station.

[0116] Among them, the first control signal is used to control the cleaning device to start the self-cleaning process, the second control signal is used to control the surface cleaning device to stop the self-cleaning process, and the third control signal is used to notify the base station to start the drying process of the roller brush.

[0117] The surface cleaning device performing a self-cleaning process on the roller brush includes: determining whether the liquid recovery part of the surface cleaning device is in place. If the liquid recovery part of the surface cleaning device is not in place, the control unit generates a first indication signal and a second control signal. The first indication signal prompts the user that the liquid recovery part is currently not in place, and the second control signal controls the surface cleaning device to stop self-cleaning. If the liquid recovery part of the surface cleaning device is in place, the surface cleaning device cleans the roller brush.

[0118] The surface cleaning device performing a self-cleaning process on the roller brush includes: determining whether the liquid stored in the recovery of the surface cleaning device reaches the liquid level threshold. If the liquid in the liquid recovery part of the surface cleaning device reaches the liquid level threshold, the control unit generates a second indication signal and a second control signal. The second indication signal indicates that the current liquid in the liquid recovery part has reached the liquid level threshold, and the second control signal controls the cleaning device to stop self-cleaning. If the liquid in the liquid recovery part does not reach the liquid level threshold, the surface cleaning device cleans the roller brush.

[0119] The drying process of the roller brush by the base station can include: determining whether the liquid recovery part of the cleaning device is in place. If the liquid recovery part of the surface cleaning device is in place, the base station dries the roller brush of the surface cleaning device. If the liquid recovery part of the surface cleaning device is not in place, the base station also dries the roller brush of the surface cleaning device. At the same time, the control unit can generate a first indication signal, and the first indication signal prompts the user that the liquid recovery part is currently not in place.

[0120] After the surface cleaning device ends the self-cleaning process of the roller brush, it further includes: the control unit generates a third indication signal, and the third indication signal is used to prompt the user to clean the liquid recovery part.

[0121] The above-mentioned first control signal, second control signal, or third control signal can be generated according to user input or automatically generated.

[0122] The cleaning system and the self-cleaning method of the cleaning system provided by the present disclosure can perform a drying process after the self-cleaning process of the roller brush of the base, or can clean the liquid recovery part such as the sewage tank while performing the drying process. In this way, after the self-cleaning process ends, the dirt in the liquid recovery part can be processed in time, and bacteria will not breed and generate peculiar smells, etc. In addition, while performing the drying process, the liquid recovery part can also be processed, so that the user does not need to wait until the long drying process ends and then clean the liquid recovery part, nor will the liquid recovery part not be cleaned due to forgetting after a long wait. This can improve the user experience during the use of the surface cleaning device and is also convenient for extending the service life of the surface cleaning device.
