Working Principle of the Window Cleaning Robot
The window cleaning robot operates through continuous power supply via the power cord, ensuring efficient and stable performance throughout the cleaning process. Its suction capability comes from the high-speed rotation of the main motor, similar to the principle of a vacuum cleaner. This generates strong suction on the glass surface, allowing the robot to firmly adhere to vertical or inclined windows and ensuring safe operation.
Once attached to the glass, the robot is driven by two walking motors that rotate the cleaning wheels, enabling it to move and wipe across the surface, achieving efficient cleaning of large glass areas. Due to the high power requirements of the main motor and walking motors, the device must remain connected to an external power source and cannot operate on battery power alone.
During operation, the high-speed rotation of the main motor may produce a certain level of noise. This is a normal part of the robot’s function, and we kindly ask for your understanding.
Troubleshooting
About Circular or Arc-Shaped Marks After Cleaning
If you notice fine circular or arc-shaped marks on the glass surface under direct sunlight or artificial light, this is a common phenomenon during the first few uses of the window cleaning robot. These traces are usually caused by residual dust, sand particles on the glass surface, or uneven distribution of liquid or microfibers on the cleaning cloth. To achieve the best cleaning results, please follow the steps below:
Step 1: Dry Wipe (Dust Removal Pre-Cleaning)
1. Turn off the automatic spray function.
2. Wipe the glass surface with a clean, dry cloth to remove dust and loose particles.
3. Replace with a new cleaning cloth to avoid scratches or streaks from residues in the old cloth.
Tip: The purpose of the first dry cleaning is to remove dust and prepare the surface for deep wet cleaning.
Step 2: Wet Wipe (Deep Cleaning)
1. Replace with a new cleaning cloth again.
2. Depending on how dirty the glass is, choose one of the following methods:
○ Option A: Turn on the automatic spray function for a full wet cleaning.
○ Option B: Keep the upper cleaning wheel dry and lightly spray 2–3 times with water, glass cleaner, or alcohol on the lower cleaning wheel cloth.
3. Let the robot clean from top to bottom for better polishing performance.
4. Note: Do not soak the cloth completely. Excess liquid will reduce suction power and affect stability.
Explanation: Circular robots use dual rotating cleaning wheels. If the cloth is too wet, friction decreases, which may cause the robot to deviate slightly or leave arc-shaped water marks.
Step 3: Dry Polish (Final Brightening)
1. Turn off the automatic spray function.
2. Use a new dry cloth for a final cleaning to remove residual moisture or circular marks.
3. This final step helps polish the glass, leaving it crystal-clear and mirror-like.
Additional Recommendations
● Wash and dry the cleaning cloth after each use to prevent stains or hardening.
● Use neutral glass cleaners and avoid oily or high-foaming liquids.
● For glass that hasn’t been cleaned for a long time, clean in three steps: dry wipe → wet wipe → final dry polish.
● Regular use of the window cleaning robot will help keep your windows clear and bright, so you can enjoy the beautiful view every day.
FAQ
1.If the window glass hasn’t been cleaned for a long time and has stubborn stains (such as bird droppings, insect marks, mud spots, sand, or grease):
Please spray water or glass cleaner directly on the stains using a spray bottle and wait for about 30 minutes to soften them. Then, manually remove the stains and any hard debris with a soft cloth or scraper to prevent hard particles in the dust from scratching the glass surface.
2. How to clean windows with a lot of dust?
We recommend manually removing surface dust first, as dust mixed with water can turn into sludge, making cleaning more difficult. After that, use the window cleaning robot in the following sequence: dry wipe → wet wipe → dry wipe.
During the cleaning process, please replace the cleaning cloths promptly to ensure optimal cleaning performance.
3. Is it compatible with frameless glass?
The window cleaning robot is suitable for vertical, seamless, and smooth surfaces such as glass windows, tiled walls, marble, or mirrors. It is equipped with edge-detection sensors that can recognize frameless edges to a certain extent. However, since frameless glass lacks physical boundaries, there is a risk that the robot may move beyond the intended cleaning area. Therefore, it is recommended to monitor the robot during the cleaning process of frameless glass and manually assist in repositioning if necessary to ensure complete and safe coverage of the cleaning area.
4. Robot runs slowly or fails when using the cleaning cloth for the first time (especially on dirty outer window glass):
A. When unpacking the robot, clean with a clean cleaning cloth.
B. Spray a little water or glass cleaner evenly on the cleaning cloth or the surface of the glass to be wiped.
C. After dampening the cleaning cloth and wringing it out until it no longer drips, place it into the cleaning ring for use.
D.The long fiber side is the front of the cleaning mops. Please avoid using it in reverse.
E. Normally, it's unnecessary to disassemble the cleaning rings for cloth replacement. If removal is needed, please carefully pair and align the cleaning bracket with the corresponding concave and convex slots. Ensuring proper alignment helps avoid air leakage and maintains stable performance.
F. If the red light still flashes, it may indicate insufficient air pressure. Please check whether the cleaning rings and mops, or the cleaning rings and cleaning wheels, are properly paired and assembled. Reinstall them to ensure a secure fit.
5. The robot doesn’t run smoothly, and there is a warning sound.
This issue may occur during the self-check at the beginning of operation. Possible causes include:
A. The cleaning cloth is too dirty, leading to reduced friction and impaired movement.
B. The surface has low friction materials (e.g., window film, frosted glass, or insulation film), which may affect the robot’s grip.
C. The glass surface is overly clean or dry, resulting in insufficient friction.
D. In low-humidity environments (such as air-conditioned rooms), the glass may become too slippery after repeated wiping.
6. When pressing the Automatic Cleaning button, the robot may fail to detect the upper edge of the window due to slipping near the top frame.
Please press the "Resume Cleaning from Breakpoint" button to continue operation.
7. The robot cannot clean the upper left side of the glass:
Use the manual cleaning mode via the remote control to clean the area that wasn’t wiped (sometimes the glass or cleaning cloth may be slippery, or the glass width is too large, causing the top line to slide and the upper left part to remain unwiped).
8. The robot finishes cleaning ahead of time and doesn't complete the entire window:
Press the "Resume cleaning from breakpoint" or "Automatic cleaning" auto clean mode to continue the unfinished cleaning.
9. The robot cannot climb or slips while climbing:
A. The friction coefficient may be too low (e.g., stickers, thermal insulation stickers, or fog stickers).
B. The cleaning cloth may be too wet. After dampening the cleaning cloth, please wring out the excess water before use.
C. The glass may be too clean and slippery.
D. Low humidity (e.g., air-conditioned rooms) can make the glass slippery after multiple wipes.
E. When starting the robot, ensure the robot is placed at a distance from the window frame to avoid incorrect detection.
F. If the robot stops working or struggles to move during cleaning, please remove it from the glass, replace the cleaning cloth with a new one, and spray a small amount of water evenly onto each cloth. Then restart the robot to resume cleaning.
10. Round wheel marks left on the glass after cleaning:
A. The cleaning cloth may be too dirty. Replace it with a clean cloth and wipe again.
B. We recommend following this cleaning sequence: start with dry wiping to remove dust, then perform wet wiping to clean the surface, and finally use dry wiping again to remove any remaining moisture. This process helps achieve the best cleaning results.
11. The robot doesn’t run smoothly:
A. Replace the dirty cleaning cloth promptly, as dirt and debris can accumulate on the cloth over time, reducing cleaning performance. Timely replacement ensures optimal cleaning results.
B. The glass surface may have different areas (e.g., glass, sticker, thermal insulation sticker, or fog sticker area). Use the robot on a single area.
C. If the cleaning wheel screw is loose, tighten it (but not too tightly, as it may affect the robot’s working performance).
12. How to handle the warning sound and red light flashing when the robot stops due to power failure:
A. Gently pull the safety rope back to the robot, ensuring it is close to the parallel glass to avoid falling.
B. Turn off the robot’s power switch.
C. Check the wire for poor contact or damage.
13. The robot stops when encountering unknown obstacles, with the red light flashing and no warning sound:
A. Use the remote control to move the robot to a safe position, or gently pull the safety rope back to the robot, keeping it as close to the glass as possible to avoid falling.
B. Remove any obstacles on the window.
C. Check if there is an air leak causing the issue.
14. Arc marks on polished glass when light shines at night:
For the first time, turn off the water spray function, clean the glass with a dry cloth to remove any sand, and replace the cloth. For the second wipe, clean again, replace the cloth, turn on the water spray function, or keep the upper cleaning wheel dry and clean, spraying a small amount of detergent or alcohol on the lower cleaning wheel (1 or 2 sprays). Do not completely wet the cloth, as it will affect the operation.
15. The robot has cleaned all the windows but doesn’t stop automatically:
Press the stop button to end the operation.
16. The robot won’t spray water:
A. Ensure that the water spray function switch is turned on.
B. Clean the ultrasonic nozzle with a soft, clean cloth.
C. Check if the water tank has water and ensure the water is clean and pure.
"D. If air bubbles appear in the water tube between the tank and the spray nozzle, they may block the water flow and affect the spraying performance. Please follow the steps below:
Keep the water tank about 50% full and place the robot upright with the water tank facing upward. Open the water tank lid, then gently shake the robot from side to side. This will help the air in the tube escape through the top of the water tank, restoring normal water flow and spray function."
17. The spray nozzle does not spray water after the robot has not been used for a while:
A. Pour out all the remaining water from the last use in the water tank, then rinse the tank thoroughly with clean water. (Limescale buildup may have clogged the spray nozzle.) After cleaning, refill the tank with clean water to restore normal functionality.
B. Turn the robot upside down, apply a few drops of clean water directly to the nozzle area to moisten the atomizing plate. Let it sit for 15 minutes, then test again. The spraying function should resume.
18.Corner Cleaning Instructions
Due to the robot’s round cleaning pad design, it is structurally limited in reaching all four corners of the window. For these areas, we recommend supplementing with manual cleaning to achieve the best overall results.
19. Maintenance in Wet Cleaning Mode and High-Humidity Environments
To maintain stable performance of the device, please follow these steps after use in wet cleaning mode or in high-humidity conditions:
1. Placement: Position the robot in a dry, well-ventilated area.
2. Drying: Allow 1–2 days for internal moisture to evaporate naturally.
3. Storage: Ensure the device is completely dry before placing it back into the packaging.
Note: Do not store the device while damp, as this may cause internal moisture damage or affect future operation.
