5. Operating Instructions

5.1. Attaching the Machine to the Glass

1. Press and hold the One-button Start button for 2 seconds to turn on the robot. Confirm that the fan rotates.
2. Wait 20 seconds after starting up until the blue light stops flashing. This allows the robot to properly detect the glass plane.
3. Place the machine on the glass surface, keeping a certain distance from the window frame.
4. Ensure the machine is safely attached to the glass before releasing your hands.

5.2. Cleaning Function

The robot offers both dry and wet wiping modes, with automatic and manual water spraying options.

Dry Wipe

For the first wipe, especially on dirty glass, perform a "dry wipe" without spraying water to remove loose sand and dust. If you spray water or detergent first, it may mix with sand to form yellow mud, reducing cleaning effectiveness. Dry wiping is best in sunny or low-humidity weather.

Wet Wipe

The robot has one water spray hole. When cleaning, it moves forward and sprays water.

• Automatic Water Spray: By default, automatic intermittent water spraying is turned on when the robot starts cleaning. Press the automatic water spray button on the remote control once to turn it off (one beep), and press it again to turn it on (two beeps).
• Manual Water Spray: During cleaning, press the Manual water spray button on the remote control to spray water once.

5.3. Intelligent Path Planning Modes

The robot can be controlled to follow different cleaning paths:

• Up-to-down: Climbs to the top and then cleans automatically downwards.
• Left-to-right: Automatically cleans from left to right.
• Right-to-left: Automatically cleans from right to left.

Figure 11: Intelligent Path Planning Modes

5.4. Power Failure Protection (Backup Battery)

In case of a power failure, the built-in backup battery activates, providing power for up to 30 minutes (when fully charged). The machine will stay in place, emit a warning sound, and the red/blue lights will flash alternately. Retrieve the machine as soon as possible using the safety rope to prevent falling.

Figure 12: Power Failure Protection

5.5. Cleaning Completed

1. Hold the window cleaner with one hand and press the One-button Start button for 2 seconds with the other hand to turn off the power.
2. Remove the window cleaning robot from the window.
3. Untie the safety rope and store the machine and its accessories in a dry, ventilated environment for next use.

6. Remote Control

The remote control allows you to manage the robot's movements and functions. Ensure proper battery installation (No., AAA/RL batteries of the same specification, aligning the negative pole with the spring first). Do not charge, disassemble, or expose remote control batteries to fire.

Figure 13: Remote Control and its Functions

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your window cleaning robot.

• Cleaning the Machine Body: Always unplug the power cord before cleaning the robot's body. Do not use water directly on the machine body or power adapter.
• Cleaning Cloths: The microfiber cleaning cloths are replaceable and machine-washable. Replace them if they become too dirty to maintain cleaning effectiveness.
• Battery Disposal: When the battery reaches the end of its life, hand it over to a local professional waste battery recycling center in accordance with national laws and regulations.
• Checking Cleaning Wheel Screws: Periodically check if the screws of the cleaning wheels are loose. If so, lock them, but do not overtighten, as this may affect the glass glue thickness or the performance of beveled window frames.

8. Troubleshooting

This section addresses common issues you might encounter and provides solutions.

1. Machine runs slowly or fails during first use (especially on dirty outer windows):
   • Clean and dry the supplied cleaning cloth before use.
   • Spray a little water or glass cleaner evenly on the cleaning cloth or the glass surface.
   • Ensure the cleaning cloth is dampened and wrung out before placing it in the cleaning ring.
2. Machine does not run smoothly or emits a warning sound (friction too large/small):
   • Check if the cleaning cloth is too dirty; replace it if necessary.
   • If using on glass with low-friction stickers, thermal insulation stickers, or fog stickers, these surfaces may not be suitable.
   • If the glass is very clean, it might be too slippery.
   • In low humidity environments (e.g., air-conditioned rooms), the glass may become too slippery after multiple wipes.
3. Machine cannot detect the upper edge of the window when pressing the up automatic cleaning button:
   • This can happen if the robot slides. Press the appropriate key on the remote to switch to a different auto clean mode.
4. Machine cannot wipe the upper left side of the glass:
   • Use the remote control's manual window cleaning mode to target the unwiped area. This can occur if the glass or cleaning cloth is slippery, the wiped area is wider, or the top line slides slightly.
5. Machine doesn't clean windows completely but finishes early:
   • Press the auto window mode button on the remote control to continue the unfinished part.
6. Slipping and not climbing:
   • Friction is too small (e.g., low-friction stickers).
   • Cleaning cloth is too wet, or the glass is very clean and slippery.
   • Low humidity can make the glass too slippery.
   • When starting, place the machine at a distance from the window frame to avoid incorrect judgment.
7. Arc marks remain on polished glass after cleaning (especially at night):
   • For the first time, turn off water spraying and use a clean cloth to remove sand.
   • For subsequent wipes, clean and replace the cloth, turn on water spraying, or keep the upper cleaning wheel clean and dry. Spray a little detergent or alcohol (1 or 2 sprays) on the lower cleaning wheel to prevent it from being completely wet. This can eliminate arc traces.
8. Machine doesn't run smoothly:
   • Cleaning cloth is too dirty; replace it.
   • If cleaning different types of glass surfaces (e.g., glass area, sticker area, thermal insulation sticker area), use it in a single area.
   • If the cleaning wheel screw is loose, tighten it (do not overtighten).
9. Warning sound and red light flashing when machine stops due to power failure:
   • Gently pull the safety rope back to the machine, keeping it close to the glass.
   • Turn off the machine power switch.
   • Check the power wire for poor contact or breakage.
10. Machine stops due to unknown obstacles (red light flashes, no warning sound):
    • Use the remote control to move the machine back to a safe position, or gently pull the safety rope back, keeping it close to the glass.
    • Remove any obstacles on the window.
    • Check for air leaks.
11. Machine cleans all windows but doesn't stop automatically:
    • Press the One-button Start button to stop the operation.

9. User Tips

• Initial Start-up: After turning on the robot, wait approximately 20 seconds for the blue light to stop flashing. This allows the robot to properly detect the glass surface before it begins cleaning.
• Safety Rope: Always attach the safety rope to a stable indoor anchor point when operating the robot, especially on high windows, to prevent accidental falls.
• Moistening Mops: For better cleaning results, spray a small amount of water or glass cleaner onto the edges of the cleaning mops before starting. However, ensure the mops are not excessively wet, as this can reduce friction and cause slipping.
• Continuous Power: The robot requires continuous power from the wall outlet to operate. The internal battery serves as a safety backup in case of a power interruption, not for cordless operation.
