The controller 114 is also configured to control the operation of the fluid delivery system 115 and the recovery system 116, and in particular may activate the water pump 1152, the roll brush motor 1162, and the suction motor 1163 on demand. For example, the controller 114 is configured to actuate the self-cleaning mode input control 111 to perform the self-cleaning mode and simultaneously activate the water pump 1152, the roll brush motor 1162, and the suction motor 1163 during the self-cleaning mode. When the water pump 1152, the roll brush motor 1162 and the suction motor 1163 are activated, the water pump 1152 sucks cleaning fluid from the supply tank 1151, the fluid distributor 1153 sprays the cleaning fluid to the roll brush and the surface to be cleaned, the roll brush motor 1162 drives the roll brush to move, the suction motor 1163 sucks used cleaning fluid and debris, etc., and recovers the used cleaning fluid and debris, etc., to the recovery tank 1161, thereby achieving the effect of sucking while washing, and making the washing cleaner.

In some embodiments, the controller 114 is configured to actuate the self-cleaning mode input control 111 to perform a simple self-cleaning mode of the self-cleaning mode when the surface cleaning apparatus 110 is not docked with the storage tray 120. That is, in the base-disconnected state, when the user actuates the self-cleaning mode input control 111, the controller 114 will perform the simple self-cleaning mode of the self-cleaning mode to simply and quickly self-clean the surface cleaning apparatus 110 during the cleaning process, thereby achieving the self-cleaning of the surface cleaning apparatus 110 in real time and at any time, and achieving the self-cleaning effect of the surface cleaning apparatus 110.

For example, during the cleaning process, the user actuates the self-cleaning mode input control 111, the controller 114 performs the simple self-cleaning mode of the self-cleaning mode, during which the controller 114 controls the water discharge speed of the water pump 1152 to be greater than the water discharge speed in the cleaning state, i.e., increases the water discharge speed of the water pump 1152 to increase the water flow rate, and controls the power of the suction motor 1163 to be greater than the power in the cleaning state, i.e., increases the power of the suction motor 1163 to increase the suction force, the roll brush motor 1162 is kept unchanged to wash the cleaning member with a large amount of water, and wash the pipe with a large suction force, thereby achieving the self-cleaning effect during the cleaning process, and since the water pump 1152, the roll brush motor 1162, and the suction motor 1163 are simultaneously operated, the effect of sucking while washing can be achieved, and the cleaning is cleaner. It should be noted that, during the simple self-cleaning mode, since the roller brush motor 1162 is in the working state, in this state, the controller 114 further controls the user interface to perform an audible and visual alert to the user, such as a voice prompt "start self-cleaning", and after hearing the voice prompt, the user stops moving the surface cleaning device 110 to suspend the surface cleaning device 110 from cleaning, so as to avoid that the surface cleaning device 110 is self-cleaned during the cleaning process, so that the cleaning members may be secondarily contaminated or water remains in the cleaned area.

In some embodiments, the controller 114 is configured to actuate the self-cleaning mode input control 111 to perform a standard self-cleaning mode of the self-cleaning mode when the surface cleaning apparatus 110 is docked with the storage tray 120. That is, in the base-connected state, the user actuates the self-cleaning mode input control 111, and the controller 114 will execute the standard self-cleaning mode of the self-cleaning mode to enable deep cleaning of the surface cleaning apparatus 110 when the surface cleaning apparatus 110 is returned to the storage tray 120, thereby enabling a second deep cleaning of the surface cleaning apparatus 110, ensuring that the surface cleaning apparatus 110 is placed in a deep-clean state.

For example, in the base-connected state, the user actuates the self-cleaning mode input control 111, the controller 114 performs a standard self-cleaning mode of the self-cleaning mode, during which there is a stage of simultaneously activating the water pump 1152, the roller brush motor 1162, and the suction motor 1163, such as at the start of the standard self-cleaning mode, the water pump 1152 starts sucking the cleaning fluid from the supply tank 1151, the fluid distributor 1153 sprays the cleaning fluid to the cleaning members such as the roller brushes, the roller brush motor 1162 drives the roller brushes to rotate, the suction motor 1163 sucks the cleaning fluid to be recovered to the recovery tank 1161, the water pump 1152, the roller brush motor 1162, and the suction motor 1163 are simultaneously activated, the cleaning fluid may be continuously supplied to the storage tray 120, the roller brush motor 1162 may perform a cleaning within the cleaning fluid, and the suction motor 1163 may operate to suck the cleaning fluid in the cleaned storage tray 120, so that the cleaning fluid in the storage tray 120 is a clean cleaning fluid, and thus the cleaning fluid may be cleanly washed within the cleaning fluid, and the cleaning fluid may be cleaner within the cleaning fluid.

Further, during the standard self-cleaning mode, the suction motor 1163 is also configured to have at least two different operating mode states, such as a first operating state activated at a first power and a second operating state activated at a second power, with the first power being less than the second power.

For example, during the standard self-cleaning mode, the water pump 1152 and the roller brush motor 1162 are first operated, the suction motor 1163 is first operated at a first power (lower power) to ensure that a certain amount of cleaning fluid is in the storage tray 120 and the cleaning fluid does not overflow the storage tray 120, the cleaning fluid can be changed into a living cleaning fluid by the suction action of the suction motor 1163, the cleaning member is cleaned in the living cleaning fluid, the effect of sucking while washing can be achieved, so that the cleaning member can be cleaned, after a while, the water pump 1152 and the roller brush motor 1162 are stopped (and can be continuously operated), and the suction motor 1163 is operated at a second power (higher power) to completely and quickly suck the cleaning fluid in the storage tray 120.

In some embodiments, during the standard self-cleaning mode, the water pump 1152 is powered by the adapter, and the brush motor 1162 and suction motor 1163 are powered by the rechargeable battery 112.

Specifically, the rechargeable battery 112 may selectively power the water pump 1152, the brush motor 1162, and the suction motor 1163. For example, in the sweeping state and during the simple self-cleaning mode performed by the controller 114, the rechargeable battery 112 supplies power to the water pump 1152, the roll brush motor 1162, and the suction motor 1163; during the standard self-cleaning mode performed by the controller 114, the water pump 1152 is powered by an external power source, such as an adapter, and the brush motor 1162 and suction motor 1163 are powered by the rechargeable battery 112.

That is, in the self-cleaning process, the power source of the water pump 1152 with lower power may be set to two channels, as shown in fig. 3, which are an external power source such as an adaptor and a rechargeable battery 112, respectively, during the simple self-cleaning mode, the switch K1 is closed, the switch K2 is open, and the water pump 1152 is powered by the rechargeable battery 112, while during the standard self-cleaning mode, the switch K1 is open, the switch K2 is closed, and the water pump 1152 is powered by the external power source such as an adaptor, so that during the standard self-cleaning mode, the power consumption of the rechargeable battery 112 is reduced, thereby on one hand, the endurance time of the rechargeable battery 112 during the self-cleaning process can be ensured, further, the self-cleaning process can be prevented from being interrupted due to insufficient power, and on the other hand, the rotation speed of the roller brush motor 1162 during the self-cleaning process can be increased under the condition of sufficient power, so that the cleaning is cleaner.

As a specific example, referring to FIG. 1, surface cleaning system 100 includes surface cleaning apparatus 110 and storage tray 120, surface cleaning apparatus 110 may include self-cleaning mode input control 111, rechargeable battery 112, base 113, controller 114, fluid delivery system 115, and recovery system 116, etc., and specific configurations may be referred to above.

In the sweeping state, the surface cleaning apparatus 110 is not docked with the storage tray 120, the rechargeable battery 112 supplies power to the water pump 1152, the roll brush motor 1162, the suction motor 1163, and the like, the water pump 1152, the roll brush motor 1162, and the suction motor 1163 are operated under the control of the controller 114, the water pump 1152 pumps cleaning fluid (e.g., water) from the supply tank 1151, the fluid distributor 1153 sprays the cleaning fluid to the roll brushes and the surface to be cleaned, the roll brush motor 1162 drives the roll brushes to move, the suction motor 1163 pumps the used cleaning fluid and debris, and the like, and recovers the used cleaning fluid and debris, and the like, to the recovery tank 1161. When the user actuates the self-cleaning mode input control 111, the user interface alerts the user to self-clean, and the user operates the surface cleaning apparatus 110 to stop cleaning while performing the simple self-cleaning mode during which the water pump 1152 discharge speed is increased to increase water flow, the suction motor 1163 power is increased to increase suction to flush the cleaning elements with bulk water and flush the pipe with bulk suction to achieve the self-cleaning effect of flushing while sucking during cleaning. When the user actuates the self-cleaning mode input control 111 again, the water pump 1152 and suction motor 1163 are restored while the user operates the surface cleaning apparatus 110 to continue sweeping.

After the sweeping is complete, the user places surface cleaning device 110 on storage tray 120, storage tray 120 receives base 113, surface cleaning device 110 interfaces with the charging contacts of storage tray 120, and the adapter of storage tray 120 begins charging rechargeable battery 112. The surface cleaning apparatus 110 is normally self-cleaned immediately after the user's sweeping is completed, so the user actuates the self-cleaning mode input control 111 for a short period of time, the rechargeable battery 112 stops charging under the control of the controller 114, and a standard self-cleaning mode is performed during which the water pump 1152 is powered by the adapter of the storage tray 120, and the brush motor 1162 and the suction motor 1163 are powered by the rechargeable battery 112 to reduce the power consumption of the rechargeable battery 112 during the standard self-cleaning mode. An automatic wash cycle may be performed during a standard self-cleaning mode, during which the water pump 1152, the roll brush motor 1162, and the suction motor 1163 are simultaneously started first, and the suction motor 1163 is operated at a lower power, the water pump 1152 is started to suck the cleaning fluid from the supply tank 1151, the fluid distributor 1153 sprays the cleaning fluid to the cleaning members such as the roll brushes and flows into the storage tray 120, the roll brush motor 1162 drives the roll brushes to rotate for the rotational washing within the cleaning fluid in the storage tray 120, the suction motor 1163 sucks the cleaning fluid at a lower power to be recovered to the recovery tank 1161, it is ensured that there is a certain cleaning fluid in the storage tray 120 and the cleaning fluid is a live cleaning fluid, so that the washing becomes cleaner, the cleanliness of the cleaning members is ensured, then the water pump 1152 and the roll brush motor 1162 are stopped, and the suction motor 1163 operates at a higher power to suck the cleaning fluid to be recovered to the recovery tank 1161. Then, after repeating the above process one or more times, the automatic cleaning cycle is ended. The rechargeable battery 112 continues to be charged until charging is complete.

In some embodiments, during the standard self-cleaning mode, there is a simultaneous activation of two of the water pump 1152, the brush motor 1162, and the suction motor 1163.

As a first implementation, the water pump 1152 is started, and then the brush motor 1162 and the suction motor 1163 are started simultaneously. Since the water pump 1152 is first activated, the cleaning members, such as the roll brushes, of the surface cleaning apparatus 110 can be washed with the cleaning fluid, and a certain amount of the cleaning fluid can be stored in the storage tray 120, so that some dirt on the cleaning members can be dissolved in the cleaning fluid and the cleaning members can be wet, and then the roll brush motor 1162 and the suction motor 1163 are activated to wash the cleaning members and suck the cleaning fluid from the washed storage tray 120, so that the cleaning fluid in the storage tray 120 can be always in a flowing state, and the dirt washed from the cleaning members can be sucked away with the cleaning fluid without being adhered to the cleaning members again, thereby accelerating the cleaning speed of the cleaning members, and reducing the possibility of dirt remaining in the storage tray 120, so that the cleaning fluid in the storage tray 120 can be ensured to be relatively clean when entering the next cycle. In this embodiment, when the brush motor 1162 and the suction motor 1163 are simultaneously activated, the water pump 1152 may be kept activated or deactivated, and if activated, the above-described effect of washing and suction may be achieved, and if deactivated, the cleaning speed of the cleaning member may be increased, thereby reducing the possibility of dirt remaining in the storage tray 120.

As a second implementation, the roll brush motor 1162 is started first, and then the water pump 1152 and the suction motor 1163 are started simultaneously. Since the rolling brush motor 1162 is first started to sweep away some granular dirt on the cleaning member of the surface cleaning apparatus 110, for example, the rolling brush, or to squeeze out the dirt in the cleaning member in a wet state, then the water pump 1152 and the suction motor 1163 are started, the cleaning member is flushed by the cleaning fluid, and meanwhile the cleaning fluid enters the storage tray 120, some granular dirt swept away from the cleaning member, the dirt squeezed out from the cleaning member, and the dirt flushed from the cleaning member by the cleaning fluid can be quickly dissolved in the cleaning fluid, and simultaneously the cleaning fluid in which the granular dirt, the dirt, and the like are dissolved in the storage tray 120 can be timely pumped away by the suction motor 1163, so that the cleaning speed of the cleaning member can be increased. It should be noted that, in this mode, when the water pump 1152 and the suction motor 1163 are simultaneously started, the roll brush motor 1162 may be kept in a starting state or a stopping state, and if the roll brush motor 1162 is kept in the starting state, the above-mentioned effect of washing and sucking while being performed can be achieved, and if the roll brush motor 1162 is kept in the stopping state, the cleaning speed of the cleaning members can be increased, and meanwhile, the cleaning members can be moistened again to prepare for next cleaning, so that more dirt can be squeezed out when a next cycle is started.

As a third implementation, the suction motor 1163 is started first, and then the water pump 1152 and the roll brush motor 1162 are started simultaneously. Since the suction motor 1163 is first activated, the cleaning fluid possibly remaining in the storage tray 120 may be completely sucked to ensure the cleanliness of the storage tray 120, and then the water pump 1152 and the roller brush motor 1162 are activated to wash the cleaning members by the cleaning fluid, and the cleaning fluid enters the storage tray 120, so that a certain amount of the cleaning fluid is stored in the storage tray 120 to sufficiently wash the cleaning members, which may reduce the usage of the cleaning fluid. In this embodiment, the suction motor 1163 may be maintained in an activated state or in a deactivated state when the water pump 1152 and the brush motor 1162 are simultaneously activated, and the aforementioned effect of washing while sucking may be achieved if the water pump is maintained in the activated state, and the cleaning member may be sufficiently cleaned in a large amount of cleaning fluid if the water pump is maintained in the deactivated state, so that the use of the cleaning fluid may be reduced, and the cleaned cleaning fluid may be sucked away by activating the suction motor 1163 at the time of the next cleaning, thereby ensuring the cleanliness of the storage tray 120.

In some embodiments, during the standard self-cleaning mode, the water pump 1152, the brush motor 1162, and the suction motor 1163 are activated in sequence.

As a first implementation, the water pump 1152 is started, the roller brush motor 1162 is started, and the suction motor 1163 is started. Since the water pump 1152 is first activated, the cleaning members, such as the roll brushes, of the surface cleaning apparatus 110 can be rinsed with the cleaning fluid, and a certain amount of the cleaning fluid can be stored in the storage tray 120, so that some dirt on the cleaning members can be dissolved in the cleaning fluid while the cleaning members are in a wet state, and then the roll brush motor 1162 is activated, so that the cleaning members can be sufficiently cleaned in a large amount of the cleaning fluid, and finally the suction motor 1163 is activated to suck the cleaned cleaning fluid away, so that the amount of the cleaning fluid used can be reduced. It should be noted that, in this manner, both the water pump 1152 and the roll brush motor 1162 which are started first can be kept in an operating state or in a stopped state, and reference is made to the foregoing description for corresponding effects, which is not described in detail herein.

As a second implementation, the water pump 1152 is started, the suction motor 1163 is started, and the roller brush motor 1162 is started. Since the water pump 1152 is first activated, the cleaning members, such as the roller brush, of the surface cleaning apparatus 110 can be rinsed with cleaning fluid, and a certain amount of cleaning fluid can be stored in the storage tray 120, so that some dirt on the cleaning members can be dissolved in the cleaning fluid while the cleaning members are in a wet state, and then the suction motor 1163 is activated, so that the cleaning fluid with the dirt dissolved therein can be timely sucked away, and finally the roller brush motor 1162 is activated to squeeze out the dirt in the cleaning members, so that the use of the cleaning fluid can be reduced. It should be noted that, in this mode, both the water pump 1152 and the suction motor 1163 which are started first can be kept in an operating state or in a stopped state, and reference is made to the foregoing description for corresponding effects, which is not described in detail herein.

As a third implementation, the roll brush motor 1162 is started first, then the water pump 1152 is started, and finally the suction motor 1163 is started. Since the rolling brush motor 1162 is first activated to sweep away some particulate dirt on the cleaning member, e.g., the rolling brush, of the surface cleaning apparatus 110, or to squeeze out the dirt in the cleaning member in a wet state, then the water pump 1152 is activated, the cleaning fluid washes the cleaning member, and the cleaning fluid enters the storage tray 120, and some particulate dirt swept off the cleaning member, the dirt squeezed out of the cleaning member, and the dirt swept off the cleaning member by the cleaning fluid can be sufficiently dissolved in the cleaning fluid, and finally the suction motor 1163 is activated to pump away the dirty cleaning fluid, thereby increasing the cleaning speed. It should be noted that, in this mode, both the roll brush motor 1162 and the water pump 1152 which are started first can be kept in an operating state or in a stopped state, and reference is made to the foregoing description for corresponding effects, which is not described in detail herein.

As a fourth implementation, the roll brush motor 1162 is started first, the suction motor 1163 is started, and the water pump 1152 is started. Since the rolling brush motor 1162 is first activated to sweep away some granular dirt on the cleaning member of the surface cleaning apparatus 110, such as the rolling brush, or to squeeze out the dirt in the cleaning member in a wet state, the suction motor 1163 is then activated to suck away the granular dirt and the dirt in time, and finally the water pump 1152 is activated to flush the cleaning member with the cleaning fluid, and the cleaning fluid enters the storage tray 120, the cleaning fluid in the storage tray 120 can be kept in a relatively clean state, and the use of the cleaning fluid can be reduced. It should be noted that, in this manner, both the roll brush motor 1162 and the suction motor 1163 which are started first can be kept in an operating state or in a stopped state, and the corresponding effects can be referred to the foregoing, and detailed description is omitted here.

As a fifth implementation, the suction motor 1163 is started first, then the water pump 1152 is started, and finally the roll brush motor 1162 is started. Because the suction motor 1163 is started first, the cleaning fluid possibly remaining in the storage tray 120 can be completely sucked away to ensure the cleanliness of the storage tray 120, then the water pump 1152 is started, the cleaning fluid washes the cleaning member, and a certain amount of cleaning fluid is contained in the storage tray 120, so that some dirt on the cleaning member can be dissolved in the cleaning fluid, and meanwhile, the cleaning member is in a wet state, and then the rolling brush motor 1162 is started, so that the cleaning member can be sufficiently cleaned in more cleaning fluid. It should be noted that, in this mode, both the suction motor 1163 and the water pump 1152 which are started first can be kept in an operating state or in a stopped state, and reference is made to the foregoing description for corresponding effects, which is not described in detail herein.

As a sixth implementation, the suction motor 1163 is started first, the roll brush motor 1162 is started, and the water pump 1152 is started. Since the suction motor 1163 is first activated, the cleaning fluid possibly remaining in the storage tray 120 may be completely sucked away to ensure the cleanliness of the storage tray 120, then the roller brush motor 1162 is activated to clean some granular dirt on the cleaning member, or the sewage in the cleaning member in a wet state is squeezed out, and finally the water pump 1152 is activated, so that the cleaning fluid washes the cleaning member, and meanwhile, the cleaning fluid enters the storage tray 120, some granular dirt cleaned off the cleaning member, the sewage squeezed out of the cleaning member, and the dirt rinsed off from the cleaning member by the cleaning fluid can be quickly dissolved in the cleaning fluid. It should be noted that, in this manner, both the suction motor 1163 and the rolling brush motor 1162 which are started first can be kept in an operating state or in a stopped state, and the corresponding effects can be referred to the foregoing, and detailed description is omitted here.
