Description

[0001] This application is a divisional application. The application number of the original application is 202411537303.7, and the original application date is October 31, 2024. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of cleaning technology, and in particular to a control method for cleaning equipment. Background Art

[0003] The cleaning equipment can clean the floor, and the cleaning task can include wet cleaning of the floor. For example, a floor scrubber includes a water sprayer and a roller brush, and the water sprayer is used to wet the floor, and then the roller brush is used to clean the wet floor stains, thereby realizing the wet cleaning function of the floor.

[0004] In order to reduce the water stain problem, existing floor scrubbers are equipped with a scraper at the front end of the roller brush so that the scraper can be used to clean the remaining water stains and impurities on the ground during the back-pulling process of the floor scrubber.

[0005] However, when adding a scraper to the front end, it also brings the risk of increased water stain contamination. For example, after the front scraper has scraped the water stains, it itself will also carry certain water stains. Therefore, it is also easy to bring the risk of increased pollution. Summary of the invention

[0006] The present application provides a control method for a cleaning device, which is used to solve the problem that the existing cleaning method for water stain residues in floor scrubbers is not perfect enough.

[0007] In a first aspect, the present application provides a control method for a cleaning device, wherein the cleaning device comprises a body and a grip connected to the rear side of the body, the grip being used to be held by a user, a floor brush being connected to the lower end of the body, the floor brush being provided with a movable first scraper and a roller brush, the first scraper being provided at the front side of the roller brush;

[0008] The method comprises:

[0009] receiving a stop command triggered by a user;

[0010] If the first scraper is in a first position in contact with the surface to be cleaned, controlling the first scraper to be lifted to a second position so that the first scraper is not in contact with the surface to be cleaned;

[0011] The cleaning device is controlled to move in a direction away from the user, and stops moving when the moving distance reaches at least a first distance.

[0012] In the current prior art, cleaning equipment often has the problem of residual water stains. For example, after cleaning, a floor scrubber has a large amount of water on the cleaning surface due to the fact that the roller brush itself contains a lot of water. Therefore, a method for solving the problem of water stains has emerged in the current prior art.

[0013] By arranging a movable scraper at the front end of the floor brush, it can be controlled to come into contact with or separate from the surface to be cleaned. When pushed forward, the front scraper rises, and when pulled backward, the front scraper descends and comes into contact with the surface to be cleaned to scrape and clean the surface to be cleaned, thereby significantly improving the problem of residual water stains on the cleaning surface. However, although the problem of residual water stains on the cleaning surface is improved, since the front scraper itself can be contaminated with some water or dirt, the front scraper is a certain distance away from the cleaning area of ​​the roller brush. Therefore, after the floor brush stops moving, the distance between the front scraper and the cleaning area of ​​the roller brush is likely to form a cleaning blind spot, so that a water stain or dirty area will be formed on the cleaning surface. For example, after cleaning is completed, the front scraper will drip water toward the surface to be cleaned, and at the same time, there is a certain gap between the front scraper and the roller brush. The above gap belongs to the dead angle position that the front scraper cannot clean before stopping.

[0014] At the same time, it is conceivable that after pressing the stop button, the user will often pull the floor scrubber closer to himself, thereby retracting the floor scrubber, and the front scraper is set in front of the floor brush. For this reason, after the front scraper drips water stains, or after water stains remain in the area between the front scraper and the roller brush, it is difficult for the user to observe when the machine is stopped. At the same time, according to behavioral habits, the user will not find the residue until he pulls the floor scrubber towards himself. Secondly, when he wants to clean again, he can only push it forward again, or turn on the floor scrubber again to clean it in a targeted manner. The experience and appearance are very poor.

[0015] This solution obtains a stop instruction and then controls the cleaning device to move so as to clean up the water stains remaining at the above-mentioned location.

[0016] When the user presses the stop button, the cleaning device receives a stop command. At this time, if the scraper set on the front side is in contact with the surface to be cleaned, the scraper is controlled to be lifted and separated from the surface to be cleaned, and the cleaning direction is controlled to move away from the user, so that the residual water stains at the above-mentioned position are cleaned with the roller brush, and the residual water stains in the dead corner of the front side can be eliminated. At the same time, lifting the scraper set on the front side can make the water stains on the first scraper fall further, and the residual water can be thrown off by the rising action, thereby preventing further residual water stains from being generated after the residual water stains are cleaned.

[0017] The above solution controls the cleaning device to move forward after obtaining a stop command, which can break the user's fixed thinking, so that the cleaning dead corners that must exist but are difficult to think of can be cleaned, thereby making the experience better.

[0018] In one embodiment of the present application, a second scraper is further provided on the body, and the second scraper is provided on the rear side of the roller brush;

[0019] After controlling the cleaning device to move in a direction away from the user, the method further includes:

[0020] When the moving distance reaches a first distance, the cleaning device is controlled to move toward a direction approaching the user, and when the cleaning device moves away from the user, the second scraper contacts the surface to be cleaned and stops moving when the moving distance reaches at least a third distance.

[0021] If the cleaning equipment is provided with a second scraper that cannot move, in order to realize the collection function of the second scraper, the second scraper needs to be grounded, and a dead angle gap will be formed between the second scraper and the roller brush. In the actual cleaning process, the dead angle area between the second scraper and the roller brush is completely hidden under the floor brush. For this reason, the user cannot foresee the residual water stains. Therefore, after shutdown, a backward movement operation is added to move towards the user, so as to clear the dead angle gap between the second scraper and the roller brush and improve the water stain cleaning effect.

[0022] To this end, on the basis of the first scraper, the second scraper is used in combination to solve the residual water stains caused by pushing forward and pulling backward respectively, and after the cleaning device obtains the stop command, the cleaning device is controlled to move away from the user and towards the user respectively, which can also solve the residual water stains caused by different scrapers themselves.

[0023] Based on this, through the combination of the above solutions, the current floor scrubber can basically produce zero water stains, and the cleaning effect and user experience far exceed those of the floor scrubbers in the existing technology.

[0024] Optionally, a water divider and a scraper strip are provided in the floor brush, the water divider is used to supply water to the roller brush to keep the roller brush in a wet state, the scraper strip is used to squeeze water from the roller brush, and a suction device is also provided in the body. When the cleaning device moves away from the user, the water divider is controlled to stop supplying water, and the suction device is kept in a suction state, so that the roller brush can absorb water stains on the surface to be cleaned during the movement of the cleaning device.

[0025] When the stop command is obtained, the water divider is controlled to stop providing water. At the same time, the ability of the scraper to squeeze water is utilized, and the suction device is controlled to suck, so as to prevent the water content of the roller brush from being in a saturated state. In this way, controlling it to move in a direction away from the user can further absorb water stains on the surface to be cleaned.

[0026] Optionally, when the cleaning device moves in a direction away from the user, the suction force of the suction device is controlled to be greater than or equal to 10000 PA.

[0027] The suction device here can be a suction motor. As mentioned above, keeping the suction force of the suction device greater than or equal to 10000PA during the movement of the cleaning equipment can further ensure that the water content of the roller brush is within a reasonable range, thereby enhancing the ability to clean residual water stains.

[0028] Optionally, the scraper bar is configured to be movable relative to the roller brush, and when the cleaning device moves in a direction away from the user, the scraper bar is controlled to move away from the roller brush, and the suction force of the suction device is controlled to be greater than or equal to 10000PA.

[0029] In one embodiment, the scraper strip is movably arranged. Specifically, a driving device, such as a cam structure, a connecting rod structure, a linear motor, etc., is arranged on the fixed side of the scraper strip. The scraper strip can be controlled to move away from or close to the roller brush through the above-mentioned drive, thereby achieving the control of the water content of the roller brush.

[0030] When the cleaning device moves away from the user, the scraper bar is controlled to move away from the roller brush, which means that water is no longer squeezed from the roller brush, that is, the roller brush is guaranteed to have a certain water content, thereby not only absorbing water stains in dead corners, but also cleaning residual stains.

[0031] At the same time, the suction force of the suction device is controlled at above 10000PA, and the suction effect after stopping can also be guaranteed. That is, the implementation of this solution can not only solve the problem of residual water stains and stains, but also ensure that the roller brush itself no longer has residue.

[0032] Optionally, after controlling the cleaning device to move in a direction away from the user, the method further comprises:

[0033] When the moving distance reaches the first distance, the cleaning device is controlled to move in the direction close to the user, and stops moving when the moving distance reaches at least the second distance, so that the debris in the dead corner gap formed between the second scraper and the roller brush can also be cleaned, and the water stain residue cleaning task is completed with the minimum driving control distance.

[0034] In one embodiment of the present application, the first distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the first scraper and the surface to be cleaned.

[0035] This embodiment limits the moving distance of the floor brush to be related to the distance between the roller brush and the first scraper, so that impurities in the dead corner gap can be cleaned more accurately to ensure that there is no missed cleaning phenomenon.

[0036] In one embodiment of the present application, the first distance is configured to be 1 / 4 to 3 / 4 of the circumference of the roller brush.

[0037] This embodiment limits the moving distance of the floor brush to the circumference of the roller brush, so that the moving distance can be indirectly controlled by simply controlling the rotation angle of the roller brush. The control method is simpler and is suitable for cleaning equipment of different models and roller brushes of different sizes, ensuring that the cleaning moving distance meets the length of the dead corner area and improving the cleaning effect of the cleaning equipment.

[0038] In one embodiment of the present application, the third distance is configured as the sum of the first distance and the second distance, and the second distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0039] Define the gap distance formed by the first scraper on the front side of the roller brush and the roller brush as the first distance, and the gap distance formed by the second scraper on the rear side of the roller brush and the roller brush as the second distance. After shutdown, since the gap distances between the two scrapers are for cleaning dead corners, moving forward the first distance can ensure that the dead corner gap on the front side of the roller brush is cleaned, and moving backward the sum of the first distance and the second distance can ensure that the dead corner gap of the second distance on the rear side of the roller brush is cleaned, while extending the backward distance, further improving the cleaning effect of the rear side of the roller brush, and restoring the first distance away from the user.

[0040] In an embodiment of the present application, when the cleaning device moves at least a third distance toward a direction approaching a user, an angle between a side of the body facing the user and the surface to be cleaned is between 70 degrees and 100 degrees.

[0041] Since the cleaning device needs to be stored upright after stopping cleaning, that is, the angle between the body and the surface to be cleaned will be between 70 and 100 degrees, the storage operation of the cleaning device can be achieved while actively cleaning the residual water stains.

[0042] In one embodiment of the present application, the second scraper is a movable scraper; if the second scraper is in a third position in contact with the surface to be cleaned, when the moving distance reaches the first distance and before controlling the cleaning device to move in a direction close to the user, the method further includes:

[0043] The second scraper is controlled to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned.

[0044] By lifting the second scraper, the dead corner area between the second scraper and the roller brush is eliminated, thereby reducing the residual impurities such as water stains in the dead corner area. Impurities attached to the second scraper can also be shaken off when the second scraper is lifted, thereby reducing the possibility of residual impurities on the second scraper falling and re-contaminating the surface to be cleaned after cleaning the water stains on the ground.

[0045] In one embodiment of the present application, the method further includes:

[0046] If the first scraper is in the second position not in contact with the surface to be cleaned, controlling the first scraper to descend to the first position so that the first scraper contacts the surface to be cleaned;

[0047] Controlling the cleaning device to move toward a direction approaching a user, and controlling the first scraper to be lifted to a second position when the moving distance reaches at least a fourth distance; the fourth distance is less than or equal to the first distance;

[0048] The cleaning device is controlled to move in a direction away from the user, and stops moving when the moving distance reaches at least a first distance.

[0049] When the cleaning task is completed when the first scraper is in the raised state, if the roller brush cannot contact the front end of the floor brush due to obstruction, the first scraper can be driven down to contact the surface to be cleaned, and then the impurities in the area that the roller brush cannot contact can be collected by pulling back. After collection, the first scraper is lifted to eliminate the dead angle area between the first scraper and the roller brush, and the floor brush is controlled to move forward again to clean up the collected impurities, thereby improving the cleaning effect of the cleaning equipment.

[0050] Optionally, if the first scraper is in the second position not in contact with the surface to be cleaned, after controlling the first scraper to descend to the first position so that the first scraper contacts the surface to be cleaned, the method further includes:

[0051] The cleaning device is controlled to move toward a direction approaching the user, and when the angle between the body and the surface to be cleaned reaches 70-100 degrees, the first scraper is controlled to be lifted to the second position, and then the cleaning device is controlled to move toward a direction away from the user, and stops moving when the moving distance reaches at least the first distance.

[0052] If the first scraper does not touch the ground when the cleaning equipment is cleaning, since the angle between the body and the surface to be cleaned during cleaning is usually less than 70-100 degrees, it will be retracted by the user to the user's side at 70-100 degrees after shutdown. During the retraction process, the roller brush may leave water stains and other impurities on the surface to be cleaned during the pulling process. In order to reduce the secondary contamination of the cleaned area by the impurities, the first scraper can be controlled to descend and contact the surface to be cleaned, so that the water stains and other impurities in the rear pulling process are collected by the first scraper, and then after lifting, the cleaning equipment is actively moved forward to clean the residual impurities in the dead corner between the first scraper and the roller brush, thereby improving the cleaning effect of the ground.

[0053] In one embodiment of the present application, a second scraper is further provided on the body, and the second scraper is provided on the rear side of the roller brush and contacts the surface to be cleaned;

[0054] After controlling the cleaning device to move toward a direction close to the user, the method further includes:

[0055] When the moving distance reaches at least a second distance, the first scraper is controlled to be lifted; the second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned;

[0056] The cleaning device is controlled to move in a direction away from the user, and stops moving when the moving distance reaches at least a first distance.

[0057] Similar to the previous embodiment, when the first scraper is not in contact with the ground, if a second scraper in contact with the ground is provided behind the roller brush, it is necessary to control the pull-back distance of the first scraper to at least reach the distance between the second scraper and the roller brush, so as to at least clean the dead corner gap between the second scraper and the roller brush, and then clean the dead corner gap between the first scraper and the roller brush, so as to achieve a shutdown effect without residual water stains.

[0058] In one embodiment of the present application, the second scraper is a movable scraper; if the second scraper is in a third position in contact with the surface to be cleaned, when the first scraper is controlled to descend to the first position, the method further includes:

[0059] The second scraper is controlled to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned.

[0060] On the basis of the above embodiment, if the second scraper is movable, lifting the second scraper before moving backward can eliminate the blind spot area between the second scraper and the roller brush, which is beneficial for the roller brush to clean impurities in this area when moving backward. At the same time, impurities such as water stains remaining on the second scraper will be shaken off when lifted, reducing the risk of impurities on the second scraper falling after shutdown and re-contaminating the cleaned surface, thereby improving the cleaning effect of the cleaning equipment.

[0061] In one embodiment of the present application, before controlling the first scraper to be lifted to the second position, the method further includes:

[0062] Maintaining the first scraper in a first position in contact with the surface to be cleaned, and controlling the cleaning device to move toward a direction approaching a user;

[0063] When the moving distance reaches at least a fifth distance, the first scraper is controlled to be lifted to a second position; the fifth distance is smaller than the first distance.

[0064] If the first scraper is already in contact with the surface to be cleaned when the machine is stopped, it can maintain this state and be pulled back to collect impurities such as water stains between the first scraper and the roller brush, and then be lifted to eliminate dead corner gaps. The lifting action can be used to shake off the impurities remaining on the first scraper to the impurity collection area, and finally the cleaning equipment can actively move forward to clean up the collected impurities, reduce the residual impurities such as water stains, and improve the cleaning effect of the cleaning equipment.

[0065] In one embodiment of the present application, a second scraper is further provided on the body, and the second scraper is provided on the rear side of the roller brush and contacts the surface to be cleaned;

[0066] After controlling the cleaning device to move toward a direction close to the user, the method further includes:

[0067] When the moving distance reaches at least a second distance, the first scraper is controlled to be lifted to a second position; the second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0068] This embodiment is similar to the previous embodiment, except that a second scraper is added, and therefore it is necessary to correspondingly increase the clearance between the cleaning roller brush and the second scraper to remove residual impurities, so as to improve the cleaning effect of the cleaning device.

[0069] In one embodiment of the present application, the second scraper is a movable scraper; if the second scraper is in a third position in contact with the surface to be cleaned, when the first scraper is controlled to descend to the first position, the method further includes:

[0070] The second scraper is controlled to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned.

[0071] Based on the above embodiment, the second scraper in fixed contact with the ground is adjusted to a movable second scraper. Therefore, when cleaning impurities in the dead angle gap between the second scraper and the roller brush, the dead angle gap can be eliminated by lifting the second scraper. Compared with the fixed contact with the ground in the above embodiment, the cleaning effect after lifting is better.

[0072] Optionally, the floor brush is further provided with a power-assisting wheel, and the power-assisting wheel is provided at the rear side of the roller brush; and controlling the cleaning device to move in a direction away from the user includes:

[0073] The roller brush and / or the power-assisting wheel are controlled to rotate in a first direction so that the cleaning device moves in a direction away from the user.

[0074] Optionally, the floor brush is also provided with a power-boosting wheel, which is arranged on the rear side of the roller brush; controlling the cleaning device to move in a direction close to the user includes: controlling the roller brush and / or the power-boosting wheel to rotate in a second direction so that the cleaning device moves in a direction close to the user.

[0075] The above-mentioned power-assisted wheel can assist the movement of the cleaning device. Of course, the roller brush itself is also a power device, and its rotation can also drive the cleaning device to move. In some embodiments, after obtaining a stop command, the rotation speed of the roller brush can be increased to be greater than the rotation speed in the normal cleaning state, so that the cleaning device can move in the intended direction. Of course, it can also be controlled by cooperating with the power-assisted wheel and the roller brush, for example, controlling the two to rotate in one direction to achieve better movement of the cleaning device.

[0076] In a second aspect, the present application provides a control method for a cleaning device, wherein the cleaning device comprises a body and a grip connected to the rear side of the body, the grip being used to be held by a user, a floor brush being connected to the lower end of the body, the floor brush being provided with a movable second scraper and a roller brush, the second scraper being provided at the rear side of the roller brush;

[0077] The method comprises:

[0078] receiving a stop command triggered by a user;

[0079] If the second scraper is in the third position in contact with the surface to be cleaned, controlling the second scraper to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned;

[0080] The cleaning device is controlled to move in a direction approaching the user, and stops moving when the moving distance reaches at least a second distance; the second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0081] When the cleaning equipment only has a movable second scraper, the dead angle area is formed only when the second scraper falls, that is, the dead angle area is the surface to be cleaned corresponding to the gap between the roller brush and the second scraper. Therefore, when the machine is stopped, it is only necessary to lift the second scraper and move the cleaning equipment backward to eliminate the dead angle gap and clean the surface to be cleaned corresponding to the dead angle area. The control method is simple, reduces the possibility of water stains remaining, and improves the cleaning effect of the cleaning equipment.

[0082] In a third aspect, the present application provides a control method for a cleaning device, the cleaning device comprising a body and a grip connected to the rear side of the body, the grip being used to be held by a user, a floor brush being connected to the lower end of the body, the floor brush being provided with a movable first scraper and a roller brush, the first scraper being provided at the front side of the roller brush;

[0083] The method comprises:

[0084] receiving a stop command triggered by a user;

[0085] If the first scraper is in a first position in contact with the surface to be cleaned, controlling the cleaning device to move in a direction close to the user;

[0086] When the moving distance reaches at least a sixth distance, controlling the first scraper to be lifted to a second position;

[0087] Control the cleaning device to move in a direction away from the user and stop moving when the moving distance reaches at least a first distance; the first distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the first scraper and the surface to be cleaned; the first distance is greater than the sixth distance.

[0088] Since the movable first scraper is in contact with the surface to be cleaned when the machine is stopped, it can maintain this state and be pulled back to collect impurities such as water stains between the first scraper and the roller brush, and then be lifted to eliminate dead corner gaps. The lifting action is used to shake off the impurities remaining on the first scraper to the impurity collection area, and finally the cleaning equipment is actively moved forward to clean up the collected impurities, thereby reducing the residual impurities such as water stains and improving the cleaning effect of the cleaning equipment.

[0089] In one embodiment of the present application, a second scraper is further provided on the body, and the second scraper is provided on the rear side of the roller brush and contacts the surface to be cleaned;

[0090] After controlling the cleaning device to move toward a direction close to the user, the method further includes:

[0091] When the moving distance reaches at least a second distance, the first scraper is controlled to be lifted to a second position; the second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0092] In one embodiment of the present application, the second scraper is a movable scraper; if the second scraper is in a third position in contact with the surface to be cleaned, when the first scraper is controlled to descend to the first position, the method further includes:

[0093] The second scraper is controlled to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned.

[0094] In a fourth aspect, the present application provides a control method for a cleaning device, the cleaning device comprising a body and a handle connected to the rear side of the body, the handle being used to be held by a user, a floor brush being connected to the lower end of the body, and a steam nozzle being provided on the front side of the floor brush so that steam can be sprayed toward a surface to be cleaned;

[0095] The method comprises:

[0096] receiving a stop command triggered by a user;

[0097] Controlling the cleaning device to stop steam spraying;

[0098] The cleaning device is controlled to move in a direction away from the user, and stops moving when the moving distance reaches at least a seventh distance.

[0099] In one embodiment, in order to solve the problem of stubborn stains in the current prior art, a steam outlet is provided on the front side of the floor brush of the floor scrubber to melt the stubborn stains by spraying steam. This method does play a certain role in cleaning stubborn stains to some extent.

[0100] However, since the steam outlet is often facing the surface to be cleaned, some steam will inevitably condense into water when it is first started or finished, which in turn increases the risk of residual water stains.

[0101] At the same time, it is conceivable that after pressing the stop button, the user will often pull the floor scrubber closer to himself, thereby retracting the floor scrubber, and the steam nozzle is arranged in front of the floor brush. Therefore, after water stains drip from the steam nozzle, or water stains remain in the area between the nozzle and the roller brush, it is difficult for the user to observe when the machine is stopped. At the same time, according to behavioral habits, the user will not find the residue until he pulls the floor scrubber towards himself. Secondly, when he wants to clean again, he can only push it forward again, or turn on the floor scrubber again to clean it in a targeted manner. The experience and appearance are very poor.

[0102] Through this solution, the movement of the cleaning device can be controlled according to the stop command after the steam is ejected, and the position where the condensed water droplets from the steam ejection outlet fall can be cleaned again, thereby solving the problem of residual water stains.

[0103] In other words, this solution can not only solve the problem of stubborn stains remaining, but also ensure that water stains are not left behind.

[0104] Of course, the first scraper and the steam nozzle can also be integrated into the front side of the floor brush, so that stubborn stains can be cleaned and residual water stains during the cleaning process can be solved, and then the mobile cleaning steam nozzle and / or the first scraper itself can be used in conjunction with the cleaning equipment to solve the water stain problem.

[0105] In one embodiment of the present application, the seventh distance is configured as the maximum distance from the contact point between the roller brush and the surface to be cleaned to the front spray range of the steam nozzle.

[0106] In one embodiment of the present application, the seventh distance is configured as the circumference length of the roller brush, for example, 160-220.

[0107] Similar to the embodiment of the first aspect mentioned above, this embodiment can also limit the moving distance of the cleaning device to clean water stains forward in two ways, namely, by limiting the distance between the roller brush of the cleaning device itself and the farthest end of the spray, or by limiting the circumference length corresponding to the rotation angle of the roller brush, thereby increasing the universality of the control method on different cleaning devices.

[0108] In one embodiment of the present application, the floor brush is further provided with a movable first scraper, and the first scraper is arranged at the front side of the steam nozzle;

[0109] After receiving the stop instruction triggered by the user and before controlling the cleaning device to move in a direction away from the user, the method further includes:

[0110] If the first scraper is in a first position in contact with the surface to be cleaned, the first scraper is controlled to be lifted to a second position so that the first scraper is not in contact with the surface to be cleaned.

[0111] In one embodiment of the present application, the method further includes:

[0112] If the first scraper is in the second position not in contact with the surface to be cleaned, the first scraper is maintained in the second position not in contact with the surface to be cleaned.

[0113] While setting the steam nozzle, a movable first scraper can also be set to limit the spray range and assist in cleaning water stains in areas that the roller brush cannot reach after spraying, thereby reducing residual spray water stains and improving the cleaning effect of the cleaning equipment.

[0114] In one embodiment of the present application, the floor brush is further provided with a second scraper, which is arranged at the rear side of the roller brush and contacts the surface to be cleaned;

[0115] After controlling the cleaning device to move in a direction away from the user, the method further includes:

[0116] When the moving distance reaches the seventh distance, the cleaning device is controlled to move in a direction close to the user, and stops moving when the moving distance reaches at least the second distance, where the second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0117] In one embodiment of the present application, the floor brush is further provided with a movable second scraper, and the second scraper is provided at the rear side of the roller brush;

[0118] After receiving the stop instruction triggered by the user, the method further includes:

[0152] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0153] Nowadays, more and more families use cleaning equipment, especially the representative floor scrubber, which is easy to operate and has strong stain cleaning ability. However, in the process of using more and more, it can be found that the current floor scrubbers still have problems, such as the problem of residual water stains. Specifically, since the roller brush is wet, there will always be more water stains remaining on the surface to be cleaned.

[0154] Based on the above technical problems, some floor scrubbers are provided with a movable front scraper, which is controlled to contact the surface to be cleaned during the cleaning push and pull, so as to simultaneously clean the residual water stains during the cleaning process.

[0155] refer to Figure 3 As shown, the front scraper is the first scraper 301. During the backward pulling process, the first scraper 301 contacts the surface to be cleaned, thereby cleaning the remaining water stains.

[0156] Please continue to refer to Figure 3 As shown, there is a gap L1 between the first scraper 301 and the bottom contact position of the roller brush 302. Since the first scraper 301 is used to clean water stains, etc., after shutdown, it and the roller brush 302 are located in the gap L1 and are prone to drip residual water.

[0157] In addition, combined with the position of the first scraper 301, which is located in front of the floor brush, it is difficult for the user to observe its actual residue. At the same time, after stopping the machine, the user is accustomed to pulling the floor scrubber backwards to put it away. For this reason, the water stains remaining in the above gap L1 are more difficult to be noticed or cleaned, and are often discovered only after the user puts away the floor scrubber. For this reason, other cleaning actions are required, which increases the labor intensity and the user experience is also poor.

[0158] Please continue to refer to Figure 3As shown, the floor scrubber also has a second scraper 303, and there is also a gap L2 between the contact position between the second scraper 303 and the roller brush and the surface to be cleaned. The above gap belongs to the lower end of the floor brush, which is more difficult for users to find. This position is also prone to become a blind spot, and water stains are easily left.

[0159] When shutting down, the scraper is first retracted to eliminate the dead corner gap, and then actively moved to the water stain area before the dead corner gap is eliminated to clean the water stain, and finally the shutdown operation is performed to clean the dead corner water stain, which aims to solve the above technical problems of the prior art.

[0160] The cleaning equipment of the present application takes a floor scrubber as an example. In the following embodiments, preset travel directions X, preset moving directions Y, and length directions Z intersecting with each other are introduced. Among them, taking the roughly flat ground as the reference of the surface to be cleaned, the preset travel direction X is roughly parallel to the surface to be cleaned, that is, the direction in which the floor brush moves roughly horizontally, the preset moving direction Y is roughly perpendicular to the surface to be cleaned, that is, roughly parallel to the height direction of the floor brush, and the length direction Z is roughly parallel to the length direction of the entire floor brush, and the length direction Z is also roughly parallel to the surface to be cleaned.

[0161] Figure 1 A schematic diagram of the overall structure of a floor scrubber provided in an embodiment of the present application; Figure 2 This is a schematic diagram of the structure of the floor brush provided in the embodiment of the present application. Figure 1 and Figure 2 As shown, the floor scrubber includes a body 100 and a handle 200 connected to the rear side of the body 100, and the handle 200 is used to be held by the user. A floor brush 300 is connected to the lower end of the body 100, and a movable first scraper 301 and a roller brush 302 are provided on the floor brush 300. The first scraper 301 is provided on the front side of the roller brush 302, so that when the floor scrubber is stopped, the user can use the first scraper 301 to collect the water stains remaining after pulling the handle 200 back to move upright. After the water stains and other impurities are collected, the first scraper 301 is controlled to move to eliminate the gap between the first scraper 301 and the roller brush 302 in the dead corner water stain area on the ground, and then the roller brush 302 is controlled to move forward so that the roller brush 302 cleans the water stains on the original dead corner water stain area.

[0162] Figure 3 This is a schematic diagram of the cross-sectional structure of a floor brush provided in an embodiment of the present application. Figure 3 As shown, the roller brush 302 is rotatably connected to the front end of the floor brush 300. The first scraper 301 is arranged at the front side of the roller brush 302 in the preset travel direction X. The floor brush 300 is also provided with a first drive assembly and a first transmission assembly. One end of the first transmission assembly is connected to the first drive assembly, and the other end is connected to the first scraper 301. The first drive assembly and the first scraper 301 are connected by the first transmission assembly.

[0163] Among them, the first driving component can drive the first transmission component to move along the length direction Z. During the movement of the first transmission component, it can synchronously drive the first scraper 301 to move along the preset moving direction Y toward or away from the surface to be cleaned 400, so that the first scraper 301 moves toward the surface to be cleaned 400 along the preset moving direction Y and reaches a first position in contact with the surface to be cleaned 400, or moves away from the surface to be cleaned 400 along the preset moving direction Y to reach a second position without contact with the surface to be cleaned 400.

[0164] It should be noted that, continue to refer to Figure 3 The roller brush 302 has a central axis O and a central section α, the central axis O is located on the central section α, and the central section α is perpendicular to the preset travel direction X. It can be understood that in this embodiment, the roller brush 302 adopts a cylindrical roller brush 302, the central axis O corresponds to the central axis O of the cylindrical roller brush 302, and at least part of the first driving component is located at the rear side of the central section α in the preset travel direction X.

[0165] When the floor brush 300 moves along the preset travel direction X, the roller brush 302 can clean the surface to be cleaned 400 along the preset travel direction X. Before the floor brush 300 is pulled back, the first transmission assembly is driven by the first drive assembly to move along the length direction Z of the roller brush 302, thereby driving the first scraper 301 to move toward the surface to be cleaned 400 and fit the cleaning surface. When the floor brush 300 is pulled back, the first scraper 301 scrapes off the dirt on the cleaning surface, which is conducive to reducing the residual water stains on the cleaning surface and improving the cleaning effect of the floor brush 300.

[0166] Continue to refer to Figure 3 As shown, the floor scrubber also includes a second scraper 303, which is arranged on the rear side of the roller brush 302 in the preset travel direction X. A second drive assembly and a second transmission assembly are also arranged inside the floor brush 300. One end of the second transmission assembly is connected to the second drive assembly, and the other end is connected to the second scraper 303. The second drive assembly and the second scraper 303 are connected through the second transmission assembly.

[0167] Among them, the second driving component can drive the second transmission component to move along the length direction Z. During the movement of the second transmission component, it can synchronously drive the second scraper 303 to move along the preset moving direction Y toward or away from the surface to be cleaned 400, so that the second scraper 303 moves along the preset moving direction Y toward the surface to be cleaned 400 and reaches a third position in contact with the surface to be cleaned 400, or moves along the preset moving direction Y away from the surface to be cleaned 400 to reach a fourth position without contact with the surface to be cleaned 400.

[0168] Optionally, the second drive assembly can drive the second transmission assembly to rotate, thereby driving one end of the second scraper 303 to rotate, so that the other end of the second scraper 303 can move in the length direction Z by means of the rotation action, thereby driving the second scraper 303 to move toward the surface to be cleaned 400 and fit the surface to be cleaned 400, or move away from the surface to be cleaned 400. In the process of pushing the floor brush 300 forward by the cleaning device, the second scraper 303 is controlled to fit the surface to be cleaned 400, so that the second scraper 303 scrapes off the dirt on the surface to be cleaned 400, which is conducive to reducing the residual water stains on the surface to be cleaned 400 and improving the cleaning effect of the floor brush 300.

[0169] Continue to refer to Figure 1 and Figure 2 As shown, the floor scrubber further includes a power-assisting wheel 304 for assisting in driving the floor brush 300 to move on the surface 400 to be cleaned.

[0170] In some embodiments, the floor scrubber is further provided with a storage component, and the processor and the storage component can be arranged inside the floor scrubber. Optionally, the storage component can be integrated with the processor, or can be two independent components of the processor.

[0171] The storage component is used to store data, for example, various software control programs, some modes and / or parameters of the floor scrubber, etc. Specifically, the program may include program codes, and the program codes include computer operation instructions.

[0172] The processor may include, for example, one or more circuits or chips having control functions.

[0173] The processor is used to control the operation of the floor scrubber and respond to user operations through various software control programs stored in the memory.

[0174] The execution subject of the embodiment of the present application can be a processor in the floor scrubber, or a server corresponding to the floor scrubber. The server is located in the cloud, connected to the processor of the floor scrubber through the network, and issues control instructions to the floor scrubber, or forwards the control instructions sent by the user through the terminal device to the floor scrubber, etc.

[0175] The following takes the processor in the floor scrubber as an example to explain the technical solution of the present application and how the technical solution of the present application solves the above technical problems in detail through specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0176] Figure 4 A schematic flow chart of a control method for a cleaning device with a movable first scraper provided in an embodiment of the present application. Figure 4 As shown, the method includes:

[0177] S401: Receive a stop instruction triggered by a user.

[0178] The stop command triggered by the user can be in various ways. For example, when a control button is provided on the cleaning device, the user directly controls the button on the cleaning device to trigger the processor of the cleaning device to generate a stop command; or, when a voice recognition module is provided on the cleaning device, the user triggers the voice recognition module of the processor of the cleaning device through voice control, thereby generating a stop command; or, when a communication module is provided on the cleaning device, the cleaning device is connected to a third-party terminal device through the communication module, and is used to send a stop request to the cleaning device through the third-party terminal device, and the cleaning device triggers the processor of the cleaning device to generate a stop command according to the stop request.

[0179] S402, determining whether the first scraper is in contact with the surface to be cleaned; if so, executing S403-S404; if not, executing S405-S407.

[0180] S403, controlling the first scraper to be lifted to a second position so that the first scraper is not in contact with the surface to be cleaned.

[0181] By lifting the first scraper, the dead angle gap can be eliminated, and the roller brush can enter the surface to be cleaned corresponding to the original dead angle gap. In addition, the action of lifting the first scraper can also make impurities such as water stains attached to the first scraper fall off, so that they can be cleaned together when the cleaning device moves forward, further improving the cleaning effect of the cleaning device.

[0182] S404: Control the cleaning device to move in a direction away from the user, and stop moving when the moving distance reaches at least a first distance.

[0183] The moving distance may be determined according to the moving distance of the floor brush; or, may be determined according to the rotation angle of the roller brush; or, may be determined according to the rotation angle of the power-assisted wheel.

[0184] For example, the first distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the first scraper and the surface to be cleaned, so that the stain cleaning in the above-mentioned gap L1 can be achieved.

[0185] By limiting the moving distance of the floor brush to be related to the distance between the roller brush and the first scraper, impurities in the dead corner gap can be cleaned more accurately to ensure that there is no missed cleaning.

[0186] For another example, the first distance is configured to be one quarter to three quarters of the circumference of the roller brush.

[0187] By limiting the moving distance of the floor brush to be related to the circumference of the roller brush, the moving distance can be indirectly controlled by simply controlling the rotation angle of the roller brush. The control method is simpler and is suitable for cleaning equipment of different models and roller brushes of different sizes, ensuring that the cleaning moving distance meets the length of the dead corner area and improving the cleaning effect of the cleaning equipment.

[0188] The above methods can accurately control the minimum cleaning area to cover all dead corners, thereby ensuring that residual water stains can be cleaned up.

[0189] A water divider and a scraper strip are provided in the floor brush 300 . The water divider is used to supply water to the roller brush to keep the roller brush in a wet state. The water divider is generally provided at the rear side of the roller brush 302 to supply water to the roller brush 302 .

[0190] The scraper bar is used to squeeze water out of the roller brush 302 . The scraper bar is also generally located at the rear side of the roller brush 302 and maintains a certain interference fit with the roller brush 302 , thereby squeezing water out of the roller brush 302 .

[0191] A suction device (not shown) is also provided in the body 100, and the suction device may be a suction motor, etc. When the cleaning device moves away from the user, the water distributor is controlled to stop supplying water, and the suction device is kept in a suction state, so that the roller brush 302 can absorb water stains on the surface to be cleaned during the movement of the cleaning device.

[0192] When the stop command is obtained, the water distributor is controlled to stop providing water. At the same time, the ability of the scraper to squeeze water is utilized, and the suction device is controlled to suck, so as to prevent the water content of the roller brush 302 from being in a saturated state. In this way, when controlling it to move in a direction away from the user, it can further absorb water stains on the surface to be cleaned.

[0193] Optionally, when the cleaning device moves in a direction away from the user, the suction force of the suction device is controlled to be greater than or equal to 10000 PA.

[0194] The suction device here can be a suction motor. As mentioned above, keeping the suction force of the suction device greater than or equal to 10000PA during the movement of the cleaning equipment can further ensure that the water content of the roller brush 302 is within a reasonable water content range, thereby enhancing the ability to clean residual water stains.

[0195] In one embodiment, the scraper bar is configured to be movable relative to the roller brush 302. When the cleaning device moves away from the user, the scraper bar is controlled to move away from the roller brush 302, and the suction force of the suction device is controlled to be greater than or equal to 10000 PA.

[0196] S405, controlling the first scraper to descend to a first position so that the first scraper contacts the surface to be cleaned.

[0197] S406: Control the cleaning device to move toward a direction close to the user, and when the moving distance reaches at least a fourth distance, control the first scraper to rise to the second position.

[0198] The fourth distance is less than or equal to the first distance.

[0199] After the first scraper comes into contact with the surface to be cleaned, water stains and other impurities in the back-pulling process are collected together by the first scraper, and the first scraper is lifted after collection to eliminate the dead angle area between the first scraper and the roller brush, and the floor brush is controlled to move forward again to clean up the collected impurities.

[0200] S407: Control the cleaning device to move in a direction away from the user, and stop moving when the moving distance reaches at least a first distance.

[0201] In this embodiment, the scraper collects impurities such as water stains on the area where the pulling path is located by pulling back. By lifting the first scraper, the dead angle gap between the first scraper and the roller brush can be eliminated. Then, the floor brush is controlled to actively move forward in the direction away from the user, so that the impurities in the area corresponding to the original dead angle gap can be cleaned up, thereby improving the water stain cleaning effect. According to the distance between the first scraper and the roller brush, the moving distance can be limited more accurately.

[0202] After receiving a stop command triggered by a user, if the first scraper is in a first position in contact with the surface to be cleaned, controlling the cleaning device to move in a direction close to the user;

[0203] When the moving distance reaches at least a sixth distance, controlling the first scraper to be lifted to a second position;

[0204] Control the cleaning device to move in a direction away from the user and stop moving when the moving distance reaches at least a first distance; the first distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the first scraper and the surface to be cleaned; the first distance is greater than the sixth distance.

[0205] Since the movable first scraper is in contact with the surface to be cleaned when the machine is stopped, it can maintain this state and be pulled back to collect impurities such as water stains between the first scraper and the roller brush, and then be lifted to eliminate dead corner gaps. The lifting action is used to shake off the impurities remaining on the first scraper to the impurity collection area, and finally the cleaning equipment is actively moved forward to clean up the collected impurities, thereby reducing the residual impurities such as water stains and improving the cleaning effect of the cleaning equipment.

[0206] Figure 5 A schematic flow chart of a control method for a cleaning device provided in an embodiment of the present application, which includes a movable first scraper and an immovable second scraper. The second scraper is disposed at the rear side of the roller brush and is always in contact with the surface to be cleaned; Figure 5 As shown, the method includes:

[0207] S501: Receive a stop instruction triggered by a user.

[0208] S502, determine whether the first scraper is in contact with the surface to be cleaned; if so, execute S503-S505; if not, execute S506-S509.

[0209] S503, controlling the first scraper to be lifted to a second position so that the first scraper is not in contact with the surface to be cleaned.

[0210] S504: Control the cleaning device to move in a direction away from the user.

[0211] S505: When the moving distance reaches the first distance, control the cleaning device to move toward a direction close to the user, and stop moving when the moving distance reaches at least a third distance.

[0212] The moving distance may be determined according to the moving distance of the floor brush; or, may be determined according to the rotation angle of the roller brush; or, may be determined according to the rotation angle of the power-assisted wheel.

[0213] For example, the first distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the first scraper and the surface to be cleaned.

[0214] For another example, the first distance is configured to be one quarter to three quarters of the circumference of the roller brush.

[0215] Exemplarily, the third distance is configured as the sum of the first distance and the second distance, and the second distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0216] Exemplarily, when the cleaning device moves at least a third distance toward a direction approaching the user, an angle between the side of the body facing the user and the surface to be cleaned is between 70 degrees and 100 degrees.

[0217] Since the cleaning device needs to be stored upright after stopping cleaning, that is, the angle between the body and the surface to be cleaned will be between 70 and 100 degrees, the storage operation of the cleaning device can be achieved while actively cleaning the residual water stains.

[0218] S506, controlling the first scraper to descend to a first position so that the first scraper contacts the surface to be cleaned.

[0219] S507: Control the cleaning device to move toward a direction close to the user.

[0220] S508: When the moving distance reaches at least the second distance, control the first scraper to rise to the second position.

[0221] The second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0222] S509: Control the cleaning device to move in a direction away from the user, and stop moving when the moving distance reaches at least a first distance.

[0223] In this embodiment, based on the original control of the moving distance, a control operation corresponding to the rearward movement of the second scraper is added according to the second scraper, so as to clean the dead angle gap between the second scraper and the roller brush and improve the water stain cleaning effect. The beneficial effects of the remaining steps are similar to the beneficial effects corresponding to the steps S401-407, and will not be described in detail in this embodiment.

[0224] Figure 6 A schematic flow chart of a control method for a cleaning device provided in an embodiment of the present application with a movable first scraper and a movable second scraper. The second scraper is disposed at the rear side of the roller brush and can be moved in contact with or out of contact with the surface to be cleaned; Figure 6 As shown, the method includes:

[0225] S601: Receive a stop instruction triggered by a user.

[0226] S602, determine whether the first scraper is in contact with the surface to be cleaned; if so, execute S603-S604; if not, execute S604, or execute S609-S611 first and then execute S604.

[0227] S603, controlling the first scraper to be lifted to a second position so that the first scraper is not in contact with the surface to be cleaned.

[0228] S604, determine whether the second scraper is in contact with the surface to be cleaned; if so, execute S605-S607; if not, execute S608.

[0229] S605: Control the cleaning device to move in a direction away from the user.

[0230] S606: When the moving distance reaches the first distance, the second scraper is controlled to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned.

[0231] The moving distance may be determined according to the moving distance of the floor brush; or, may be determined according to the rotation angle of the roller brush; or, may be determined according to the rotation angle of the power-assisted wheel.

[0232] For example, the first distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the first scraper and the surface to be cleaned.

[0233] For another example, the first distance is configured to be three quarters of the circumference of the roller brush.

[0234] S607: Control the cleaning device to move toward the user and stop when the moving distance reaches at least a second distance.

[0235] The second distance is configured as the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0236] S608: Control the cleaning device to move in a direction away from the user, and stop moving when the moving distance reaches at least a first distance.

[0237] Exemplarily, when the cleaning device moves at least a third distance toward a direction approaching the user, an angle between the side of the body facing the user and the surface to be cleaned is between 70 degrees and 100 degrees.

[0238] S609, controlling the first scraper to descend to a first position so that the first scraper contacts the surface to be cleaned.

[0239] S610: Control the cleaning device to move toward a direction close to the user.

[0240] S611. When the moving distance reaches at least the second distance, control the first scraper to rise to the second position.

[0241] The second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0242] In this embodiment, the second scraper in the above embodiment is set as a movable second scraper, so when cleaning the dead angle gap between the second scraper and the roller brush, the contact between the second scraper and the surface to be cleaned can be controlled to further reduce the water stains remaining in the dead angle gap, thereby improving the cleaning effect of the cleaning device. The beneficial effects of the remaining steps are similar to the beneficial effects corresponding to the steps S401-407, and will not be repeated in this embodiment.

[0243] Figure 7 A schematic flow chart of another control method for a cleaning device with a movable first scraper provided in an embodiment of the present application. Figure 7 As shown, optionally, based on the above embodiment, before executing S403 or S503 or S603, if the first scraper is in the first position in contact with the surface to be cleaned, the following steps may also be performed:

[0244] S701, maintaining the first scraper at a first position in contact with the surface to be cleaned, and controlling the cleaning device to move toward a direction approaching the user.

[0245] S702: When the moving distance reaches at least the fifth distance, control the first scraper to rise to the second position.

[0246] The fifth distance is smaller than the first distance.

[0247] This embodiment mainly utilizes the first scraper that has contacted the surface to be cleaned to collect impurities such as water stains in the gap formed between the first scraper and the roller brush. When moving forward after the collection, the collected impurities will not be unable to be cleaned due to the inability to continue moving forward because they have retreated and then moved forward. This ensures that the impurities will be completely cleaned, thereby improving the cleaning effect of the cleaning equipment.

[0248] Figure 8 A flow chart of a control method for a cleaning device with a steam nozzle provided in an embodiment of the present application. The steam nozzle is arranged at the front side of the floor brush so that steam can be sprayed toward the surface to be cleaned; the floor brush is also provided with a movable first scraper, which is arranged at the front side of the steam nozzle; the floor brush is also provided with a second scraper, which is arranged at the rear side of the roller brush and contacts the surface to be cleaned; Figure 8 As shown, the method includes:

[0249] S801. Receive a stop instruction triggered by a user.

[0250] S802, controlling the cleaning device to stop spraying steam.

[0251] S803, determine whether the first scraper is in contact with the surface to be cleaned; if so, execute S804-S806; if not, execute S805-S806.

[0252] S804, controlling the first scraper to be lifted to a second position so that the first scraper is not in contact with the surface to be cleaned.

[0253] S805: Control the cleaning device to move in a direction away from the user.

[0254] The moving distance may be determined according to the moving distance of the floor brush; or, may be determined according to the rotation angle of the roller brush; or, may be determined according to the rotation angle of the power-assisted wheel.

[0255] For example, the seventh distance is configured as the maximum distance from the contact point between the roller brush and the surface to be cleaned to the front spray range of the steam nozzle.

[0256] For another example, the seventh distance is configured as the circumference of the roller brush.

[0257] S806: When the moving distance reaches the seventh distance, control the cleaning device to move in a direction close to the user, and stop moving when the moving distance reaches at least the second distance.

[0258] The second distance is the minimum distance between the contact point between the roller brush and the surface to be cleaned and the contact point between the second scraper and the surface to be cleaned.

[0259] Optionally, if the second scraper in contact with the surface to be cleaned is movable, after executing S805, the following steps may also be performed:

[0260] S807, controlling the second scraper to be lifted to a fourth position so that the second scraper is not in contact with the surface to be cleaned.

[0261] S808: Control the cleaning device to move a second distance toward the user.

[0262] In this embodiment, a steam nozzle is added to the cleaning device on the basis of the above embodiment. Since the newly added steam nozzle will form water stains after spraying water, it is necessary to control the moving direction and moving distance accordingly to clean the water stains in the area after the water spraying, thereby improving the cleaning effect of the cleaning device. The beneficial effects of the remaining steps are similar to the beneficial effects corresponding to the steps S401-407, and will not be repeated in this embodiment.
