If "external cleaning mode" is understood to mean: the mode of cleaning the floor, table top, wall or window etc. outside the cleaning device, then the "self-cleaning mode" is the mode of cleaning the internal components of the cleaning device itself. For example, as shown in fig. 11a, the cleaning assembly 20 may include, but is not limited to: rags, a roll brush 230, a recycling pipe 220, a recycling bin 210, etc. The second electric connection port 1 is used for electrically connecting a charging power supply and can output a current I1 from the charging power supply.

When the cleaning device is operated in the self-cleaning mode, the charging and discharging device can provide the current I1 for the battery unit and simultaneously provide the working current for the working load 5 of the cleaning device. In the technical scheme provided by the application, when the cleaning equipment works in the self-cleaning mode, the controller controls the charging control circuit 2 to supply at least part of the current I1 from the charging power supply to the working load 5 in the self-cleaning mode, so that the power consumption of the battery unit of the cleaning equipment is reduced, the endurance time of the battery unit in the self-cleaning process is prolonged, the self-cleaning process of the cleaning equipment is ensured to be smoothly completed by the cleaning equipment, meanwhile, the electric energy of the battery unit of the cleaning equipment can be effectively prevented from being exhausted in the self-cleaning process, and the use experience of a user is improved.

Referring to fig. 1 to 3, in one embodiment provided in the present application, when the cleaning device completes the cleaning operation and is plugged with the charger, the current from the charging power source, which is accessed through the second electrical connection port 1, may be fully supplied to the battery for charging after passing through the charging control circuit 2, as shown in fig. 1, when the self-cleaning process is not started. As shown in fig. 2, when the cleaning apparatus enters the self-cleaning mode, if the working current required by the working load 5 is less than the total current from the charging power supply, the current from the charging power supply and received by the second electrical connection port 1 can be divided into two parts, one part is the second current I5 for charging the battery, and the other part is the working current I6 required by the working load 5. As shown in fig. 3, when the operating current required by the workload 5 is greater than the total current from the charging power supply, the operating current I6 required by the workload 5 is composed of two parts, one part is the current I1 from the charging power supply and is accessed through the second electrical connection port 1, and the other part is the output current I7 output by the battery. Alternatively, when the operating current required by the workload 5 is greater than the current I1 from the charging power source, which is accessed through the second electrical connection port 1, the operating current I6 required by the workload 5 is independently provided by the battery of the cleaning apparatus.

There is also provided in an embodiment of the present application a cleaning system, as shown in fig. 11a, 11b and 1, comprising: a base 70 and the cleaning device 10. Wherein, a first electric connector (not shown in the figure) is arranged on the base, and the first electric connector can be electrically connected with a charging power supply through an electric connector. Or the first electric connecting port is electrically connected with the charger through an electric connecting piece. In addition, a controller and a second electrical connector 1 are arranged on the cleaning device 10, the controller is electrically connected with the second electrical connector 1, and when the cleaning device 10 is placed on the base 70, the second electrical connector 1 and the first electrical connector can be mutually contacted and electrically connected. When the cleaning device is removed from the base 70, the second electrical connection port 1 is disconnected from the first electrical connection port and the electrical connection therebetween is cut off. The controller is also used to perform a charging and discharging method of the cleaning apparatus, which will be described in detail below. The embodiments provided in the present application are described in detail below by specific scenarios. After the user performs a sweeping operation using the cleaning device or autonomously by the cleaning device, the user places the cleaning device 10 on the base 70, as shown in fig. 11 b. After the cleaning device is placed on the base 70, the second electrical connector 1 of the cleaning device is electrically connected to the first electrical connector of the base, so as to connect to the charging power source through the first electrical connector. At this time, the second electrical connection port 1 receives a current from the charging power supply to charge the battery 4 in the battery unit. At the moment, the user touches the self-cleaning control piece through the interaction device on the cleaning equipment, at the moment, the cleaning equipment enters a self-cleaning mode, and the working assembly on the cleaning equipment starts to work according to the control instruction of the controller. When the working current consumed by the self-cleaning working load is less than or equal to the total current of the second electrical connection port 1 connected to the self-charging power supply in the self-cleaning mode, the current from the charging power supply supplies the self-cleaning working load with current, and if the current is surplus, the surplus current is supplied to the battery 4 for charging. When the current consumed by the self-cleaning working load is larger than the total current of the second electric connector 1 connected to the self-charging power supply, the battery 4 is converted into a discharging state and provides working current for the self-cleaning working load 5 together with the charging power supply electrically connected with the second electric connector 1, so that the self-cleaning process of the cleaning equipment can be smoothly completed.

The user has used the cleaning device some time ago (e.g., three days or a week), and when the user needs to use the cleaning device again, the cleaning device needs to complete one self-cleaning. Since the battery 4 is fully charged after the last time of use, when the user places the cleaning device on the self-cleaning base 70, the battery 4 will start the charging protection, and when the working current required by the working load 5 is larger than the total current from the charging power source connected to the second electrical connection port, the battery 4 is turned to the discharging state and provides the working current I6 for part of the working load 5 together with the current from the charging power source connected to the second electrical connection port 1, so that the working current required by the working load 5 is equal to the input working current, and the duration of the cleaning device can be prolonged while ensuring the normal operation of the working load 5.

The above is that the distribution of current is determined by means of the actual current demand of the working load when the cleaning device is operating in the self-cleaning mode. In addition, the charging control circuit can be controlled to intermittently charge the battery through the stage of the cleaning device in the self-cleaning mode. For example, the self-cleaning mode includes a plurality of self-cleaning phases, such as a preparation phase and a cleaning phase. Wherein the preparation phase may further comprise: and a soaking stage of preparing a sterilization liquid, accumulating the sterilization liquid and soaking the self-cleaning object in the sterilization liquid. During the preparation stage, the charging control circuit can be controlled to charge the battery, and during the cleaning stage, the charging control circuit is controlled to stop charging the battery, and the battery supplies power to the self-cleaning working load so as to execute the cleaning stage. The following examples will explain the relevant matters.

The embodiment of the application also provides a charging and discharging method of the cleaning equipment. Fig. 4 is a first schematic flow chart of a charging and discharging method according to an embodiment of the present disclosure, and referring to fig. 4, the charging and discharging method of a cleaning device according to the embodiment of the present disclosure includes:

s101, operating in a self-cleaning mode to clean the self-cleaning object on the cleaning equipment.

And S102, providing at least part of current from the charging power supply to a working load in the self-cleaning mode.

In an embodiment provided by the present application, the main body of the charging and discharging method is the cleaning apparatus, and specifically, may be a controller of the cleaning apparatus. In step S101, the cleaning apparatus may be switched from another operation mode to the self-cleaning mode, or may enter the self-cleaning mode after the shutdown state is triggered by the user. The work load 5 is a main executive body which may be the object of self-cleaning while cleaning. For example, in the self-cleaning mode, the roller brush is a self-cleaning object, and the roller brush is driven by a roller brush motor to rotate during self-cleaning, so that the roller brush completes self-cleaning operation.

In step S102, the current supplied to the work load from the current from the charging power supply may be determined by the rated power of the work load 5. In addition, the work module includes a plurality of component parts, and the work load 5 is at least a part of the plurality of component parts. The working components may include, but are not limited to: a rolling brush driving device, a main motor generating suction force, a transfusion device outputting cleaning liquid, a bacteria removing liquid preparation device and the like.

In one embodiment provided herein, see fig. 5, wherein the step of "providing at least part of the current from the charging power source to the work load in the self-cleaning mode" comprises:

and S103, acquiring the state information of the cleaning equipment.

And S104, when the state information meets a first preset condition, providing the current from the charging power supply and the current output by the cleaning equipment battery to the working load. Or

And S104', when the state information meets a second preset condition, supplying part of current from the charging power supply to the working load, and supplying the rest of current from the charging power supply to a battery of the cleaning equipment for charging.

In S103, the status information of the cleaning device may include a first current corresponding to the working load in the self-cleaning mode. Correspondingly, the method provided by the embodiment may further include the following steps:

acquiring total current from a charging power supply;

if the first current is greater than the total current, the first preset condition is met;

or, if the first current is less than or equal to the total current, the second preset condition is met.

Further, when the cleaning device performs step S104 or step S104', it can perform step S103 at the same time, and the controller controls the corresponding component to regulate and control the current, and also obtains the status information of the cleaning device, and during the process of obtaining the status information of the cleaning device, it may be a continuous process, or an intermittent process, or starts to obtain the status of the device before a specific step according to the setting of the user.

Further, the cleaning apparatus can alternately perform step S104 or step S104' a plurality of times during the self-cleaning. For example, when the cleaning device is performing the first step of self-cleaning, the device for preparing the sterilization solution is preparing the sterilization solution, and the current consumed by the device for preparing the sterilization solution is smaller than the maximum current that can be provided by the charging power source connected to the second electrical connection port 1, so the cleaning device performs step S104'. When the cleaning device is in the second step of self-cleaning, the water pump supplies water to the rolling brush, and meanwhile, the rolling brush motor drives the rolling brush to rotate and the main motor operates to generate suction force. The working current consumed by the working load 5 in operation is larger than the maximum current which can be provided by the charging power supply connected to the second electrical connection port 1, and the cleaning equipment performs the second step of self-cleaning and is shifted from the step S104' to the step S104. Then, when the cleaning device is in the third step of self-cleaning, only the water pump provides the sterilizing liquid for the roller brush, the maintenance work after cleaning is completed, and at this time, the other working loads 5 do not work. Since the operating current consumed by the operating load 5 is less than the maximum current that can be supplied by the charging power source connected to the second electrical connection port 1, the cleaning device performs the second step of self-cleaning and is shifted from the execution step S104 to the execution step S104'. In the technical scheme provided by the application, different steps can be executed under different preset conditions according to the actual state information of the cleaning equipment, so that the duration of the cleaning equipment can be prolonged under the condition that the stable operation of the working load 5 is met.

In another embodiment provided herein, referring to fig. 6, the step S102 "providing at least a portion of the current from the charging power source to the working load in the self-cleaning mode" may include:

s105, acquiring stage information of the cleaning equipment in a self-cleaning mode;

s106, when the stage information meets a third preset condition, providing part of current from a charging power supply to the working load, and providing the rest part of current from the charging power supply to a battery of the cleaning equipment for charging; or

S106', when the stage information meets a fourth preset condition, discharging the battery of the cleaning equipment to provide electric energy for the working load.

Further, when the cleaning device is left for a long time (a year or more), the power consumption of the battery 4 of the cleaning device is low and is not enough to supply power to the working load 5 simultaneously with the second electrical connector 1 in the self-cleaning process, and at this time, when the cleaning device performs self-cleaning, the self-cleaning process is first suspended, and the current of the charging power source connected through the second electrical connector 1 is output to the battery 4 to charge the battery. When the electric quantity of the battery 4 reaches a certain range, the self-cleaning work is continued. For example, the self-cleaning mode is continuously activated when the battery reaches 20%, 30%, or 50%.

In one embodiment provided herein, the self-cleaning mode includes a plurality of phases, such as including: a preparation phase and a cleaning phase. The preparation phase may include, but is not limited to: and a soaking stage of preparing a sterilization liquid, accumulating the sterilization liquid and soaking the self-cleaning object in the sterilization liquid. The cleaning phase may include, but is not limited to: such as rolling brush cleaning, recycling pipeline cleaning and cleaning piece dehydration.

Correspondingly, the method provided by the embodiment may further include the following steps:

s107, when the stage information is the preparation stage, the third preset condition is met; or

And S108, when the stage information is the cleaning stage, the fourth preset condition is met.

Further, referring to fig. 7, in an embodiment of the present application, a charging and discharging method for a cleaning device further includes the following steps:

and S109, detecting the residual capacity of the battery of the cleaning equipment.

And S110, when the residual capacity is greater than or equal to the set threshold, discharging the battery of the cleaning equipment to supply power to the working load in the self-cleaning mode.

S110', when the remaining capacity is less than the set threshold, triggering the step of providing at least part of the current from the charging power source to the working load in the self-cleaning mode.

In the above steps, the execution main body for detecting the remaining capacity of the battery 4 may be a detection device disposed on the battery 4 or the discharge control circuit 3, and the step of detecting the remaining capacity of the battery 4 can be performed in the whole self-cleaning process or can be set to be performed in different stages.

In step S110, the battery of the cleaning apparatus may be discharged by intercepting the input of the current. The "disconnection" may be to cut off the electrical connection between the charging control circuit 2 and the second electrical connection port 1, or to close the charger on the cradle 70 or to open and close the first electrical connection port by controlling the charging control circuit 2.

The embodiment of the application also provides another charging and discharging method of the cleaning equipment. Referring to fig. 8, the charge and discharge method includes:

s201, working in a self-cleaning mode to clean a self-cleaning object on a cleaning device; wherein the self-cleaning mode comprises a plurality of phases.

S202, in at least part of the plurality of stages, the battery of the cleaning device is charged by current from a charging power source.

In an embodiment provided by the present application, the main execution body of the charging and discharging method is the above cleaning device, and specifically, may be a controller of the cleaning device. In step S101, the cleaning apparatus may be switched from another operation mode to the self-cleaning mode, or may enter the self-cleaning mode after the shutdown state is triggered by the user. The work load 5 is a main executive body which may be the object of self-cleaning while cleaning. For example, in the self-cleaning mode, the roller brush is a self-cleaning object, and the roller brush is driven by a roller brush electric appliance to rotate during self-cleaning, so that the roller brush completes self-cleaning operation.

In step S201, the multiple stages of the self-cleaning mode include, but are not limited to: a preparation phase, a cleaning phase and a maintenance phase. The preparation phase may include, but is not limited to: a soaking stage of preparing a sterilization liquid, accumulating the sterilization liquid, soaking the self-cleaning object in the sterilization liquid, and the like. The washing stage includes, but is not limited to: such as rolling brush cleaning, recycling pipeline cleaning, cleaning piece dehydration and the like. The maintenance phase includes, but is not limited to: bacteriostasis treatment, drying treatment and the like. In addition, in step S202, at least some of the stages may be a preparation stage and a maintenance stage, in which the current charges a rechargeable battery of the cleaning device, since the current consumed by the working load of the cleaning device is less than the maximum current that can be supplied by the first electrical connection port.

Further, referring to fig. 9, in one embodiment provided herein, the plurality of phases of the self-cleaning mode includes a preparation phase and a washing phase, wherein "at least part of the plurality of phases, the current charges the battery of the cleaning device" further includes the steps of:

s203, acquiring stage information of the cleaning equipment in the self-cleaning mode.

And S204, when the stage information is the preparation stage, providing part of current from the charging power supply to the working load, and providing the rest part of current from the charging power supply to a battery of the cleaning equipment for charging.

In the above steps, the charging and discharging mode of the cleaning device at the stage is judged by judging the stage of the cleaning device. In one embodiment provided herein, when the controller determines that the cleaning apparatus is in a preparation phase, the preparation phase may include, but is not limited to: and a soaking stage in which the sterilization liquid is prepared, the sterilization liquid is accumulated, the self-cleaning object is soaked in the sterilization liquid, and the like, the controller controls the charging circuit to supply partial current from the charging power supply to the working load, and the rest current from the charging power supply is supplied to the battery of the cleaning equipment for charging. The cleaning equipment can be set in advance in which stage the different steps belong to in the self-cleaning process, for example, the stages corresponding to the steps are set before the cleaning equipment leaves a factory, the sterilization liquid preparation belongs to the preparation stage, and the rolling brush cleaning and the recovery pipeline cleaning can be set as the cleaning stages. Or the determination is made according to the magnitude of the average working current of the working load during working, for example, when the cleaning device is in the sterilization liquid preparation stage, and the current required by the sterilization liquid preparation device is less than or equal to the maximum current which can be provided by the charging power supply connected through the second electrical connection port, it is determined that the step belongs to the preparation stage. When the cleaning equipment is in the cleaning step of the recovery pipeline, and the total working current required by the main motor is larger than the maximum current which can be provided by the charging power supply connected through the second electric connection port, the step is judged not to belong to the preparation stage and to belong to the cleaning stage.

The charging and discharging method for the cleaning equipment provided by the embodiment of the application further comprises the following steps:

s205, when the stage information is a washing stage, providing the current from a charging power supply and the current output by the cleaning equipment battery to the working load; or

S205', when the stage information is a cleaning stage, discharging a battery of the cleaning equipment to supply power to a working load in a self-cleaning mode.

In the above steps, the cleaning phase of the cleaning device may be that the working current required by the working load of the cleaning device at this phase is greater than the maximum current which can be provided by the charging power source connected through the second electrical connection port 1. In the cleaning stage, the battery provides electric energy for the work load together with the current provided by the charging power supply in the discharging state, so that the work load can be ensured to operate stably.

In another embodiment provided herein, when the cleaning apparatus is in the washing phase, the current is interrupted and the work load in the self-cleaning mode is powered only by the battery of the cleaning apparatus. The current interruption may be performed by controlling the charging control circuit 2 to interrupt the electrical connection with the second electrical connection port 1, or by controlling the charging control circuit 2 to turn off the charger on the cradle 70 or to turn off the first electrical connection port. In one embodiment provided herein, the self-cleaning process is broadly divided into four phases: preparing a sterilization liquid, soaking by using a rolling brush, cleaning and recovering a pipeline, and dehydrating by using the rolling brush. The specific cleaning process can be referred to the following table.

In the above table, the rolling brush soaking includes two steps, which may be cycled back and forth several times until the rolling brush is cleaned. In addition, "the sterilization liquid preparation" in the table indicates that the sterilization liquid preparation apparatus prepares the sterilization liquid, which can be obtained by electrolyzing the cleaning liquid in one embodiment. Wherein the cleaning solution can be common clear water or clear water containing sodium chloride. After the self-cleaning process is started, firstly, preparing a sterilization liquid: the main motor in the cleaning equipment is turned off, the rolling brush motor is turned off, the infusion device is turned off, the bacteria-removing liquid preparation device is turned on, the charging circuit works (the charging control circuit 2 outputs current), and the current from the charging power supply charges the battery 4 and supplies power to the bacteria-removing liquid preparation device.

Then, the rolling brush soaking comprises two stages, namely a rolling brush soaking stage (A1) and a liquid stopping rolling brush rotating stage (A2). When the main motor in the cleaning equipment is closed in the infiltration stage of the rolling brush, sewage cannot be sucked, the infusion device conveys the sterilization liquid to the rolling brush, the rolling brush motor stops rotating, the sterilization liquid preparation device is started or closed at the moment, the charging circuit works, and the current from the charging power supply charges the battery 4 and supplies power to the infusion device. When the bacteria-removing liquid preparation device is started, the current from the charging power supply supplies power to the bacteria-removing liquid preparation device. In the liquid stopping roller brush rotation stage, the main motor stops rotating, the roller brush motor rotates and drives the roller brush to rotate together, the infusion device stops conveying the bacteria removing liquid to the roller brush, the bacteria removing liquid preparation device is started or closed, the charging circuit stops charging the battery, and the roller brush motor and the bacteria removing liquid preparation device (when started) are powered by the battery or powered by the battery and a charging power supply together.

Subsequently, the recovery pipe is cleaned: the main motor is turned on and the suction force of the main motor is in a dynamically changing state. So that the accumulated liquid can be cleaned back and forth on the recovery pipeline. The rolling brush motor is started to enable accumulated liquid on the rolling brush to be scraped completely, in addition, the infusion device is closed, the bacteria removing liquid preparation device is started or closed, the charging circuit stops charging the battery, and the main motor, the rolling brush motor and the bacteria removing liquid preparation device (when started) are powered by the battery or the battery and the charging power supply are powered together.

And finally, in the charging stage, after the cleaning equipment finishes all cleaning works, the work load 5 stops working, the charging circuit works, and at the moment, the current output by the second electric connector 1 and derived from the charging power supply is transmitted to the end of the battery 4 to charge the battery.

In summary, according to the technical scheme provided in the embodiment of the present application, when the cleaning device operates in the self-cleaning mode, the charging control circuit 2 is controlled to supply at least part of the current from the charging power source to the working load in the self-cleaning mode, so that the power consumption of the battery unit is reduced, the endurance time of the battery unit in the self-cleaning process is increased, the cleaning device is ensured to smoothly complete the self-cleaning process, and meanwhile, the power consumption of the battery unit can be effectively prevented, so that the use experience of the user is improved.

Fig. 10 is a schematic flow chart illustrating a charging and discharging method of a cleaning device according to another embodiment of the present application. As shown in fig. 10, the method includes:

s301, working in a self-cleaning mode to clean a self-cleaning object on the cleaning equipment; wherein the self-cleaning mode comprises a plurality of phases.

S302, at least one load of the cleaning equipment in the working state at the current stage is determined at least in part of the stages;

s303, respectively selecting a corresponding power supply source for the at least one load from a plurality of power supply sources;

For the contents of S301 and S302, reference may be made to the contents of the above embodiments. For example, in S302, for example, the rolling brush soaking stage in the multiple stages adopts the strategy in this embodiment (i.e., steps S302 and S303 are performed). Still alternatively, the rolling brush soaking stage and the cleaning and recycling pipeline stage in the multiple stages adopt the strategy in the present embodiment (i.e., steps S302 and S303 are performed).

In the above S302, if the cleaning device is currently in the rolling brush soaking stage, referring to the above table, it can be determined that the load of the cleaning device in the working stage is: a main motor and a rolling brush motor.

If the cleaning device is currently in the rolling brush soaking phase, it can be determined, referring to the table above, that the load of the cleaning device currently in operation is: a transfusion device and a rolling brush motor.

Further, each stage in this embodiment may be further divided into a plurality of sub-stages. For example, the roll brush soak phase may include a drain soak phase a1 and a roll brush rotation self-cleaning phase a 2. In the drainage and infiltration stage A1, the work load is the infusion device; when the roller brush rotates the self-cleaning stage A2, the working load is the roller brush motor.

In the above S303, a configuration table may be preset, where the configuration table includes: phase information and associated power supply allocation policies. As in table 2 below:

here, it should be noted that: the above table schematically shows one possibility, which is not limited by the embodiments of the present application. The configuration information for selecting and configuring the power supply for the load may be determined according to actual design, product characteristics, and the like.

In another implementation solution, the step S303 "selecting a corresponding power supply source for the at least one load from a plurality of power supply sources" may include:

s3031, acquiring the energy consumption attribute of the at least one load;

3032, respectively selecting power supply sources suitable for respective energy consumption attributes for the at least one load from the plurality of power supply sources.

The energy consumption attributes in S3031 may include, but are not limited to: current, voltage, load power consumed by the load, etc., which are not limited in this embodiment. Therefore, when step S3032 is executed, an appropriate power supply source can be selected for each load according to the energy consumption property of the load.

In this embodiment, the step S3032 may be executed according to a preset matching rule. The matching rule is not limited in this embodiment.

Further, the loads that are working at the same stage include at least a first load and a second load. Correspondingly, in step S303 "respectively select a corresponding power supply source for the at least one load from the multiple power supply sources, which may specifically be:

different power supplies are selected for the first load and the second load from a plurality of power supplies.

For example, in the above-mentioned stage of cleaning and recycling the pipeline, the power supply corresponding to the main motor is a charging power supply, and the power supply corresponding to the rolling brush motor is a battery.

Or, the plurality of stages includes at least a first stage and a second stage; the power supply source corresponding to the first stage is different from the power supply source corresponding to the second stage. Correspondingly, in this embodiment, the step S303 "respectively select and allocate a corresponding power supply source for the at least one load from the plurality of power supply sources", may specifically be:

determining a power supply source corresponding to the current stage of the cleaning equipment in the plurality of power supply sources;

and respectively matching a power supply corresponding to the current stage of the cleaning equipment for the at least one load.

In specific implementation, a relation table between each stage and the power supply source can be preset, so that the power supply source corresponding to the current stage of the cleaning equipment can be determined according to the relation table. For example, the power supply source corresponding to the preparation stage may be a battery; the power supply source for the cleaning stage (due to its high energy consumption) may be a charging power source.

In the scheme provided by the embodiment of the application, different power supplies are distributed for two different loads, or different power supplies are equipped in different stages, so that electric energy provided by the power supplies can be reasonably distributed, and the time consumed by battery charging can be reduced while the energy consumption of the battery is saved. For example, different power supplies are distributed to two different loads, the power supplies can be reasonably distributed according to the actual energy consumption of each load, the cleaning equipment cannot work due to unreasonable selection of the power supplies, and meanwhile, the energy consumption can be saved. Different power supplies are equipped in different stages, for example, a first-stage charging power supply is used as a power supply to provide electric energy for all loads working in the stage, and a battery in the next stage provides electric energy for all loads working in the stage; the charging power supply can charge the battery if residual current exists when supplying power to the load in the first stage; that is to say, the cleaning equipment charges the battery in a stage manner in the self-cleaning process, so that the energy consumption of the battery can be saved, and the cleaning equipment is effectively ensured to complete the self-cleaning task. Charging the battery at some of the multiple stages also saves charge time.

For example, a cleaning tank 710 is disposed on the base 70, and a floor brush of the cleaning apparatus is disposed in the cleaning tank 710, so that self-cleaning can be performed in the cleaning tank. The base 70 is further provided with a water storage bucket 720, and the inside of the water storage bucket 720 can be provided with an electrolysis electrode to prepare a sterilization liquid.
