[0056] Hereinafter, various embodiments of the present application will be described more fully. The present application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present application to the specific embodiments disclosed herein, but rather that the present application should be understood to cover all adjustments, equivalents and / or alternatives that fall within the spirit and scope of the various embodiments of the present application.

[0057] Hereinafter, the terms "include" or "may include" as used in various embodiments of the present application indicate the presence of disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. In addition, as used in various embodiments of the present application, the terms "include", "have" and their cognates are intended only to indicate specific features, numbers, steps, operations, elements, components, or combinations of the foregoing, and should not be understood as first excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing or the possibility of adding one or more features, numbers, steps, operations, elements, components, or combinations of the foregoing.

[0058] Embodiments of the present invention provide a window-cleaning robot configured to attach to a surface to be cleaned and perform cleaning. The window-cleaning robot described herein is simply named based on a specific application scenario. Its application can be expanded to cleaning surfaces such as walls and ceilings, and it may also be referred to as a wall-cleaning robot or a ceiling-cleaning robot. Accordingly, the surface to be cleaned may be a window, wall, ceiling, or the like.

[0059] like Figure 1 、 2 As shown, the present application provides a window cleaning robot, comprising:

[0060] Body 1;

[0061] Cleaning device 2, cleaning device 2 is used to clean the surface to be cleaned;

[0062] A steam generating device 3, used for generating cleaning liquid steam from the cleaning liquid;

[0063] A spray head 4 is provided on the machine body 1;

[0064] At least one of the cleaning device 2 and the spray head 4 is used to spray cleaning liquid vapor.

[0065] The present application converts the cleaning liquid into cleaning liquid steam by setting a steam generating device 3, and enables the spray head 4 and / or the cleaning device 2 to spray cleaning liquid steam. Compared with ordinary cleaning liquid, the cleaning liquid steam has a stronger penetration ability and can penetrate deeper into the tiny gaps and stains on the surface to be cleaned, effectively softening and decomposing stubborn stains, thereby solving the problem of oil stains and oil films that are difficult to remove without using chemical detergents. At the same time, at least one of the spray head 4 and the cleaning device 2 can spray cleaning liquid steam, providing a variety of cleaning methods. Users can flexibly choose to pre-treat local stains by spraying cleaning liquid steam only through the spray head 4, or let the cleaning device 2 spray cleaning liquid steam during the cleaning process, or let the cleaning device 2 and the spray head 4 spray cleaning liquid steam simultaneously during the cleaning process, to achieve more comprehensive cleaning and meet the cleaning needs in different scenarios.

[0066] The present application also provides another window cleaning robot, comprising:

[0067] Body 1;

[0068] Cleaning device 2, cleaning device 2 is used to clean the surface to be cleaned;

[0069] A steam generating device 3, used for generating cleaning liquid steam from the cleaning liquid;

[0070] The cleaning device is used to spray cleaning liquid steam.

[0071] Compared with the aforementioned window cleaning robot, this window cleaning robot does not have a spray head 4, but converts cleaning liquid into cleaning liquid steam through a steam generating device 3 and sprays the cleaning liquid steam through a cleaning device 2. Other parts are the same as the aforementioned window cleaning robot.

[0072] In the window cleaning robot of this embodiment, the shape of the body 1 can be disc-shaped, elliptical disc-shaped, square, rectangular, etc. The body 1 has an outer shell, and an installation cavity is formed in the outer shell. The installation cavity is used to install other components of the window cleaning machine, such as a control device, a negative pressure device, etc., including but not limited to these. The window cleaning robot also includes a walking device arranged on the body 1, specifically located on the side of the body 1 facing the surface to be cleaned. When the window cleaning machine is placed on the surface to be cleaned (such as window glass), the walking device contacts the surface to be cleaned, and generates friction between the surface to be cleaned and the surface to be cleaned during operation, so as to drive the body 1 to move on the surface to be cleaned. Among them, the walking device can adopt a turntable walking device, and specifically can be a single-disc structure or a multi-disc structure. The walking device can also be a roller structure, a crawler structure, etc., which can be set according to actual needs. When the walking device is a single-disc structure, the cleaning component generates friction between the single disk and the surface to be cleaned to achieve machine movement; when the walking device is a multi-disc structure, the disks are coaxially arranged, and the walking device can generate friction between a part of the disks and the surface to be cleaned to achieve machine movement.

[0073] like Figure 2 As shown, the cleaning device 2 includes a first cleaning member 21 and a second cleaning member 22. At least one of the first cleaning member 21 and the second cleaning member 22 is provided with a through hole. The cleaning liquid steam is used to spray toward the surface to be cleaned through the through hole, thereby more comprehensively covering the area to be cleaned 201, effectively cleaning stains hidden deep inside, greatly improving the cleaning depth, and at the same time, the cleaning liquid steam is evenly sprayed on the cleaning device 2, making the cleaning device 2 evenly wet, thereby ensuring the uniformity of cleaning and avoiding the occurrence of cleaning dead corners. In addition, since at least one of the first cleaning member 21 and the second cleaning member 22 is provided with a through hole, the user can flexibly choose to use the first cleaning member 21 for steam cleaning, the second cleaning member 22 for steam cleaning, or the first cleaning member 21 and the second cleaning member 22 for steam cleaning at the same time according to actual cleaning needs, thereby improving the flexibility of cleaning.

[0074] like Figure 2 As shown, the first cleaning member 21 and the second cleaning member 22 both include a cleaning disc 207. At least one of the cleaning discs 207 of the first cleaning member 21 and the cleaning discs 207 of the second cleaning member 22 is provided with a plurality of randomly distributed through holes, through which cleaning liquid vapor is sprayed to clean the surface to be cleaned.

[0075] In this embodiment, the cleaning disc 207 of the second cleaning member 22 is provided with a plurality of randomly distributed through holes, and the cleaning liquid vapor is sprayed through the through holes to clean the surface to be cleaned. The cleaning liquid vapor is sprayed toward the surface to be cleaned through the through holes of the second cleaning member 22, thereby greatly improving the cleaning depth.

[0076] Furthermore, the cleaning disc 207 of the first cleaning member 21 and / or the cleaning disc 207 of the second cleaning member 22 is covered with a cleaning cloth 208 , and the cleaning cloth 208 receives the cleaning liquid steam sprayed from the through hole and cleans the surface to be cleaned.

[0077] In this embodiment, the structure of the first cleaning member 21 is the same as that of the second cleaning member 22. The first cleaning member 21 includes a cleaning disc 207 and a cleaning cloth 208. The cleaning disc 207 is provided with a plurality of randomly distributed through holes, and the cleaning cloth 208 covers the cleaning disc 207. Similarly, the second cleaning member 22 also includes a cleaning disc 207 and a cleaning cloth 208. The cleaning disc 207 is provided with a plurality of randomly distributed through holes, and the cleaning cloth 208 covers the cleaning disc 207.

[0078] like Figure 2 、 8 As shown, when the window cleaning robot is running, the first cleaning member 21 is located above the second cleaning member 22, and the steam generating device 3 is arranged on the first cleaning member 21 so that the cleaning liquid steam flows to the spray head 4 and the second cleaning member 22, and at least one of the spray head 4 and the second cleaning member 22 sprays the cleaning liquid steam. The present application uses the positional relationship between the first cleaning member 21, the second cleaning member 22 and the steam generating device 3 to automatically flow the cleaning liquid steam generated in the steam generating device 3 into the spray head 4 and the second cleaning member 22 under the action of gravity, so that the cleaning liquid steam can efficiently reach the spray head 4 and the second cleaning member 22, thereby improving the utilization rate of the steam and making the cleaning liquid steam play the greatest role in the cleaning process. It should be noted that the cleaning liquid steam generated in the steam generating device 3 can also flow to the first cleaning member 21, and the steam generating device 3 can also be arranged on the body 1 and correspond to the position of the first cleaning member 21, as long as it can be ensured that the steam generated by the steam generating device 3 can automatically flow into the spray head 4 and the second cleaning member 22 under the action of gravity.

[0079] like Figure 4 As shown, a storage space 33 is provided inside the steam generating device 3. The steam generating device 3 is used to heat and evaporate the cleaning liquid entering the storage space 33 to form cleaning liquid steam. The heated steam generating device 3 is also used to dry the corresponding surface to be cleaned. The steam generating device 3 of the present application can not only heat and evaporate the cleaning liquid entering the storage space 33 to form cleaning liquid steam for cleaning, but also use its own heat to dry the surface to be cleaned. This allows the window cleaning robot to dry the surface to be cleaned without additional operation after completing the cleaning task, reducing energy consumption, improving cleaning efficiency, avoiding problems such as dust re-attachment or water stains caused by long-term moisture, and achieving a better cleaning effect on the surface to be cleaned.

[0080] Specifically, the heating steam generating device 3 first heats the corresponding first cleaning member 21, and the heated first cleaning member 21 then dries the corresponding surface to be cleaned. Therefore, a through hole can be provided on the first cleaning member 21 to dissipate heat to the surface to be cleaned through the through hole; or no through hole is provided, and the heat is directly transferred to the surface to be cleaned through the surface of the first cleaning member 21.

[0081] In this embodiment, the cleaning disk 207 of the first cleaning member 212 is provided with a plurality of randomly distributed through holes, and the heat spontaneously generated by the steam generating device 3 is transferred to the surface to be cleaned through the through holes on the cleaning disk 207 of the first cleaning member 212, so that the window cleaning robot can dry the surface to be cleaned without additional operation after completing the cleaning task, thereby reducing energy consumption, improving cleaning efficiency, avoiding problems such as dust re-adhesion or water stains caused by long-term moisture, and achieving a better cleaning effect on the surface to be cleaned.

[0082] like Figure 3 As shown, the steam generating device 3 includes:

[0083] a liquid supply device 31 for providing a cleaning liquid that meets a threshold condition;

[0084] The heating device 32 is used to generate heat to generate cleaning liquid steam from the cleaning liquid, and is used to generate heat to heat the cleaning device 2.

[0085] The present application uses the liquid supply device 31 to provide a cleaning liquid that meets the threshold conditions, thereby avoiding the delivery of liquid of substandard quality to the heating device 32, reducing the generation of scale that affects the heating effect, and avoiding nozzle blockage. The heat generated by the heating device 32 not only vaporizes the internal cleaning liquid to produce cleaning liquid vapor, but also generates heat to heat the cleaning device 2, achieving efficient energy utilization. In the process of generating cleaning liquid vapor and supplying it to the cleaning device 2 to clean the surface to be cleaned, the heating device 32 also fully utilizes the generated heat for the cleaning device 2, further enhancing the cleaning ability of the cleaning device 2 by heating the cleaning device 2.

[0086] like Figure 3 、 4 As shown in Figures 5 and 6, the liquid supply device 31 includes a water tank 311, a water pump 312, and a water quality detection device 313. The water tank 311 has a water inlet 3111 for introducing external liquid. The water quality detection device 313 is disposed within the water tank 311 and is used to detect the water quality of the liquid within the water tank 311. The water pump 312 is connected to the water tank 311 and the storage space 33, respectively, and is used to output cleaning liquid that meets the threshold condition to the storage space 33. The heating device 32 is disposed on the cleaning device 2 and is used to generate heat to generate cleaning liquid steam from the cleaning liquid in the storage space 33, which flows out through the steam outlet 34 of the steam generating device 3. The heating device 32 is also used to generate heat to heat the cleaning device 2.

[0087] In this embodiment, the water quality detection device 313 includes a TDS sensor.

[0088] In summary, the steam generating device 3 has multiple working states, and the steam generating device 3 is used to adjust the working state so that the cleaning device 2 has multiple cleaning modes.

[0089] The steam generating device 3 has the following working states: a first state for generating heat; a second state for converting the cleaning liquid into cleaning liquid steam; and a third state for spraying the cleaning liquid.

[0090] The heat generated by the steam generating device 3 in the first state is used to dry the cleaning device 2 and / or the surface to be cleaned, so that the cleaning device 2 has a dry wiping mode;

[0091] The steam generated by the steam generating device 3 in the second state acts on the cleaning device 2 and / or the surface to be cleaned, so that the cleaning device 2 has a steam cleaning mode.

[0092] The steam generating device 3 is used in the third state to spray cleaning fluid onto the cleaning device 2 and / or the surface to be cleaned, so that the cleaning device 2 has a wet wiping mode.

[0093] The liquid supply device 31 of the steam generating device 3 is used to supply cleaning liquid, enabling the steam generating device 3 to have a third state; the heating device 32 of the steam generating device 3 is used to generate heat, enabling the steam generating device 3 to have a first state; and the heating device 32 and the liquid supply device 31 work together to enable the steam generating device 3 to have a second state. This application uses the coordination of the liquid supply device 31 and the heating device 32 to enable the steam generating device 3 to have multiple operating states. This allows the cleaning device 2 to have multiple cleaning modes, including dry wiping mode, steam cleaning mode, and wet wiping mode, by adjusting the operating state, thereby achieving more comprehensive cleaning and meeting cleaning needs in different scenarios.

[0094] Furthermore, the steam generating device 3 is also used to make the first cleaning member 21 of the cleaning device 2 and the second cleaning member 22 of the cleaning device 2 have different cleaning states, so that the cleaning device 2 has a mixed cleaning mode, thereby achieving more comprehensive cleaning and meeting the cleaning needs in different scenarios.

[0095] In this embodiment, the mixed cleaning mode includes: the first cleaning member 21 steam cleans the surface to be cleaned, and the second cleaning member 22 dry cleans the surface to be cleaned. The second cleaning device 2 is used to clean the surface to be cleaned after the first cleaning device 2 has cleaned it.

[0096] like Figure 6 、 7As shown, the body 1 is provided with a steam diffusion device 5, which is arranged corresponding to the second cleaning member 22. The second cleaning member 22 rotates relative to the steam diffusion device 5, and the cleaning liquid vapor passes through the steam diffusion device 5 to reach the second cleaning member 22. In this application, by arranging the steam diffusion device 5 corresponding to the second cleaning member 22 and allowing the second cleaning member 22 to rotate relative to the steam diffusion device 5, the cleaning liquid vapor is more evenly distributed around the second cleaning member 22 and the area of ​​action, avoiding localized over-cleaning or under-cleaning, thereby improving overall cleaning quality. Furthermore, during rotation, the second cleaning member 22 is able to more fully come into contact with the cleaning liquid vapor evenly distributed through the steam diffusion device 5. By fully wetting and carrying the components of the cleaning liquid vapor, the cleaning member's ability to soften, dissolve, and remove stains is enhanced.

[0097] In this embodiment, if Figure 1 As shown, the steam diffusion device 5 includes a steam diffusion pipe 52, which is arranged corresponding to the second cleaning member 22. A transmission assembly 10 is provided on the body 1, and the second cleaning member 22 rotates relative to the steam diffusion device 5 through the transmission assembly 10, so that the cleaning liquid vapor passes through the steam diffusion device 5 and reaches the second cleaning member 22.

[0098] like Figure 6 As shown, the steam diffusion device 5 is also provided with through holes, and the cleaning liquid steam is used to be evenly sprayed out through the through holes of the steam diffusion device 5, thereby ensuring the uniformity of cleaning and avoiding the occurrence of cleaning dead corners.

[0099] In this embodiment, the through hole of the first cleaning member 21 is a first through hole 23, and multiple first through holes 23 are randomly distributed on the first cleaning member 21 and connected to the accommodating cavity of the first cleaning member 21, so as to increase the range of action of the steam generating device; the through hole of the steam diffusion device 5 is a second through hole 53, and multiple second through holes 53 are evenly distributed on the steam diffusion device 5. The cleaning liquid vapor is used to be evenly sprayed through the second through holes 53 of the steam diffusion device 5, and randomly sprayed through the first through holes 23 of the first cleaning member 21, thereby improving the cleaning effect.

[0100] like Figure 4 、 5 As shown in , 7 , the steam generating device 3 has a steam outlet 34, and the steam diffusing device 5 has a steam inlet 51; a pipeline 8 is provided between the first cleaning member 21 and the second cleaning member 22, and one end of the pipeline 8 between the first cleaning member 21 and the second cleaning member 22 is connected to the steam outlet 34 of the steam generating device 3, and the other end is connected to the steam inlet 51 of the steam diffusing device 5, so that the cleaning liquid steam generated by the steam generating device 3 flows from the first cleaning member 21 to the second cleaning member 22 through the pipeline 8.

[0101] Furthermore, a one-way valve 9 is provided on the pipeline 8 between the first cleaning member 21 and the second cleaning member 22. The design of the one-way valve 9 makes the flow direction of the cleaning liquid vapor single to avoid backflow.

[0102] like Figure 4 、 5 As shown, there are two spray heads 4, which are located on both sides of the bottom of the body 1; a pipeline 8 is also provided between the first cleaning member 21 and the spray head 4. One end of the pipeline 8 between the first cleaning member 21 and the spray head 4 is connected to the steam outlet 34 of the steam generating device 3, and the other end is connected to the spray head 4, so that the cleaning liquid vapor generated by the steam generating device 3 flows from the first cleaning member 21 into the spray head 4 through the pipeline 8.

[0103] Furthermore, a one-way valve 9 is also provided on the pipeline 8 between the first cleaning member 21 and the spray head 4. The design of the one-way valve 9 makes the cleaning liquid vapor flow in a single direction to avoid backflow.

[0104] like Figure 4 As shown, the cleaning device 2 includes a heating area 203 and an adsorption area 202. The adsorption area 202 is used to form a negative pressure space between the adsorption area 202 and the surface to be cleaned, so that the window cleaning machine is adsorbed on the surface to be cleaned;

[0105] The heating area 203 is located outside the adsorption area 202 and is used to form a heating space between the adsorption area 203 and the surface to be cleaned;

[0106] A sealing member 6 is provided between the heating area 203 and the adsorption area 202 , and the sealing member 6 is used to separate the cleaning space from the heating space.

[0107] The present invention utilizes the suction region 202 to create a negative pressure space between the surface to be cleaned, allowing the window cleaning robot to securely adhere to the surface to be cleaned, significantly improving the safety and reliability of the window cleaning robot. Furthermore, the heating region 203 is located outside the suction region 202, forming a relatively independent heating space between the surface to be cleaned. The sealing member 6 separates the heating space from the negative pressure space, preventing interference between the heating and cleaning spaces and improving the reliability of the window cleaning machine.

[0108] like Figure 7 As shown, the cleaning device 2 further includes a cleaning area 201 and an adsorption area 202. The adsorption area 202 is used to form a negative pressure space between the adsorption area 202 and the surface to be cleaned, so that the window cleaning machine is adsorbed on the surface to be cleaned;

[0109] The cleaning area 201 is located outside the adsorption area 202 and is used to form a cleaning space between the cleaning area and the surface to be cleaned;

[0110] A seal 6 is provided between the clean area 201 and the adsorption area 202 , and the seal 6 is used to separate the clean space from the negative pressure space.

[0111] This application utilizes suction area 202 to create a negative pressure space between the surface to be cleaned, allowing the window cleaning robot to securely adhere to the surface to be cleaned, significantly improving the safety and reliability of the window cleaning robot. Furthermore, by locating cleaning area 201 outside suction area 202, a relatively independent cleaning space is formed between the surface to be cleaned. Seal 6 separates the cleaning space from the negative pressure space, preventing wastewater, dust, and other debris generated during the cleaning process from entering the negative pressure space and impacting the adsorption effect. Furthermore, the independent cleaning space allows cleaning area 201 to focus more on cleaning the surface to be cleaned, improving the thoroughness and effectiveness of cleaning.

[0112] like Figure 1 As shown, the window-cleaning robot also includes an ambient pressure monitor 7, and a steam generator 3 for adjusting operating power according to the ambient pressure. Specifically, the ambient pressure monitor 7 is used to detect the ambient pressure of the window-cleaning robot; the steam generator 3 is used to adjust operating power according to the ambient pressure. Through the cooperation between the ambient pressure monitor 7 and the steam generator 3, the relative operating power is selected under different ambient pressures, thereby ensuring a certain stability in the steam cleaning effect. At the same time, the window-cleaning robot can quickly adapt to these changes. Regardless of the cleaning scene, it can perform steam cleaning in an optimal state and meet the cleaning requirements of different scenarios.

[0113] The ambient pressure monitor 7 is arranged on a side of the machine body 1 close to the surface to be cleaned.

[0114] Specifically, in areas with higher altitudes, the boiling point of the cleaning liquid is lower than that under normal atmospheric pressure, and the energy required for steam vaporization is smaller. By selecting the relative working power under different ambient pressures, energy consumption can be reduced, and the steam cleaning effect can also have a certain stability.

[0115] The window-cleaning robot also includes a negative pressure blower for attaching the robot to the surface to be cleaned. The robot adjusts the suction power of the negative pressure blower according to the ambient pressure, thereby ensuring a more stable attachment of the robot to the surface to be cleaned and improving product reliability. Furthermore, the negative pressure in the suction area 202 can be adjusted according to the ambient pressure, allowing for a corresponding suction power to be selected under different ambient pressures to improve the robot's suction stability.

[0116] Example 2

[0117] like Figure 9 As shown, based on the window cleaning robot of the present application, the present application further provides an operating method of the window cleaning robot, which is applied to the window cleaning robot of Example 1. The operating method of the window cleaning robot includes:

[0118] Control the window cleaning robot to run on the surface to be cleaned;

[0119] Controlling at least one of the spray head 4 and the cleaning device 2 to spray cleaning liquid steam toward the surface to be cleaned, and steam cleaning the surface to be cleaned through the cleaning device 2;

[0120] The other cleaning device 2 after being heated is controlled to dry-wipe the area wiped by the cleaning liquid steam.

[0121] The present application controls at least one of the spray head 4 and the cleaning device 2 to spray cleaning liquid steam, and the steam can penetrate into the tiny gaps and pores of the surface to be cleaned, effectively softening stubborn stains such as oil stains, glue stains, etc.; and the other heated cleaning device 2 is used to dry-wipe the area wiped by the cleaning liquid steam, so that the residual stains and moisture can be thoroughly removed more easily, so that the surface to be cleaned is clean and free of residue, greatly improving the cleaning quality of surfaces such as windows.

[0122] Controlling at least one of the spray head 4 and the cleaning device 2 to spray cleaning liquid steam toward the surface to be cleaned includes:

[0123] Control the spray head 4 to spray cleaning liquid steam onto the surface to be cleaned to perform the first steam cleaning;

[0124] controlling a cleaning device 2 to spray cleaning liquid steam onto the surface to be cleaned to perform a second steam cleaning;

[0125] The heated cleaning device 2 is controlled to dry-clean the area wiped by the cleaning liquid steam, including:

[0126] The other cleaning device 2 after being heated is controlled to perform a third dry cleaning on the area wiped by the cleaning liquid steam.

[0127] The present application first performs a first steam cleaning on the dirt on the surface to be cleaned through the spray head 4 (i.e., pre-spraying to soften the stains on the surface to be cleaned), and when the window cleaning robot passes the surface to be cleaned, a cleaning device 2 is used to spray cleaning liquid steam to the surface to be cleaned for a second steam cleaning (i.e., steam wiping cleaning). After the second steam cleaning, another heated cleaning device 2 is controlled to perform a third dry wiping cleaning (i.e., residual heat drying cleaning) on ​​the area wiped by the cleaning liquid steam, so as to dry the condensed water remaining on the glass, reduce the water stains remaining on the glass, and thus improve the cleaning effect.

[0128] In this embodiment, the cleaning device 2 includes a first cleaning element 21 and a second cleaning element 22. Therefore, controlling at least one of the spray head 4 and the cleaning device 2 to spray cleaning liquid vapor toward the surface to be cleaned and steam cleaning the surface to be cleaned by the cleaning device 2 includes: controlling the spray head 4 to spray cleaning liquid vapor toward the surface to be cleaned for a first steam cleaning; and controlling the second cleaning element 22 to spray cleaning liquid vapor toward the surface to be cleaned for a second steam cleaning. Controlling the heated cleaning device 2 to dry-wipe the area wiped with the cleaning liquid vapor includes: controlling the heated first cleaning element 21 to dry-wipe the area wiped with the cleaning liquid vapor for a third time. The present application first performs a first steam cleaning (i.e., pre-spray softening cleaning) on ​​the dirt on the surface to be cleaned through the spray head 4, and when the window cleaning robot passes the surface to be cleaned, the second cleaning component 22 sprays cleaning liquid steam to the surface to be cleaned for a second steam cleaning (i.e., steam wiping cleaning). After the second steam cleaning, the heated first cleaning component 21 is controlled to perform a third dry wiping cleaning on the area wiped by the cleaning liquid steam, so as to dry the condensed water remaining on the glass, reduce the water stains remaining on the glass, and thus improve the cleaning effect.

[0129] The cleaning liquid vapor can be water vapor, commercially available cleaning agent vapor, or a mixture of water and commercially available cleaning agent vapor. Specifically, at least one spray head 4 is provided. When one spray head 4 is provided, the spray head 4 is positioned on one side of the cleaning device 2 in the direction of travel. When two spray heads 4 are provided, the two spray heads 4 are positioned on both sides of the cleaning device 2. The spray head 4 can be positioned at various locations on the main body 1, such as on the side or bottom surface of the main body 1.

[0130] When the window cleaning robot is working, the spray head 4 sprays cleaning liquid steam toward one side of one of the cleaning devices 2, so that the spraying range of the spray head 4 is within the wiping range of the cleaning device 2 and does not affect the other cleaning device 2, that is, the spray head 4 will not wet the other cleaning device 2, so that one of the cleaning devices 2 can perform steam wiping and the other cleaning device 2 can perform dry wiping.

[0131] Optionally, the two cleaning devices 2 rotate in opposite directions when wiping the same surface area to be cleaned.

[0132] For example, Figure 8As shown, when the window cleaning robot is cleaning the window, one of the cleaning devices 2 (the first cleaning member 21) of the window cleaning robot rotates in the counterclockwise direction, and the other cleaning device 2 (the second cleaning member 22) rotates in the clockwise direction. The window cleaning robot moves laterally to the right under the rotation of the first cleaning member 21 and the second cleaning member 22. The second cleaning member 22 is arranged below the first cleaning member 21, and the spray head 4 sprays the cleaning liquid in the direction to be moved. The spray head 4 sprays the cleaning liquid steam into the first area 100a that the second cleaning member 22 is about to wipe, so as to wet the first area 100a and perform the first steam cleaning; then the second cleaning member 22 moves to the wet first area 100a and sprays the cleaning liquid steam on the surface to be cleaned for the second steam cleaning; the first cleaning member 21 The cleaning element 21 performs a dry wipe on the second area 100b. The window cleaning robot then returns to clean, moving downward. The second cleaning element 22 enters the area below the first area 100a, and the first cleaning element 21 enters the first area 100a. The second cleaning element 22 rotates clockwise, while the first cleaning element 21 rotates counterclockwise. The window cleaning robot then moves laterally to the left. The spray head 4 sprays cleaning fluid in the same direction to wet the next area for a first steam clean. The second cleaning element 22 performs a second steam clean on the next wetted area, while the first cleaning element 21 performs a dry wipe on the wet-wiped first area 100a to remove any water stains. This cycle continues, completing the window cleaning. Thus, the cleaning robot of this embodiment simultaneously performs both steam and dry wipe functions, effectively avoiding water stains left after wet wiping and improving cleaning effectiveness. Optionally, when the second cleaning member 22 rotates clockwise to wet-wipe the first area 100a, the remaining water stains are in the clockwise direction. When the first cleaning member 21 dry-wipes the first area 100a, the first cleaning member 21 is rotated counterclockwise. The rotation direction of the first cleaning member 21 is opposite to the direction of the water stains, making it easier to wipe the water stains clean.
