2. Safety Guidelines
Adherence to these safety guidelines is crucial for preventing accidents and ensuring proper device function.
- Always connect the safety rope to a secure anchor point before operation, especially for high-rise windows.
- The robot must remain connected to a power source during operation. The integrated UPS system provides temporary power in case of an outage, allowing safe retrieval.
- Ensure the window glass surface is larger than 60 x 40 cm (23.6 x 15.7 inches) for optimal cleaning. The machine may not clean the entire surface on smaller windows.
- Do not use the W120-DP on windows with irregular frame shapes, flat corners, or cracked glass.
- Use only tap water in the water tank. Purified water is not suitable and may trigger a 'no water' alert.
- For initial use, fully charge the internal UPS battery for approximately 40 minutes before connecting to power for cleaning.

The Mamibot W120-DP offers a safer alternative to manual high-rise window cleaning, featuring multiple fall protection systems.

Key safety features include a robust safety rope, an integrated Uninterruptible Power Supply (UPS) for power loss, adjustable suction, and fall protection sensors.

- Placement: Place the W120-DP vertically on the window surface and hold it.
- Activate Suction: Hold and press the switch button on the W120-DP for about 3 seconds to activate the suction. Once suction is firm, release the robot onto the window glass.

Step 1: Prepare the robot by charging, attaching the cleaning cloth, filling the water tank, and securing the safety rope.

Step 2: Connect the robot to a power source and await the voice prompt.

Step 3: Position the robot vertically on the window, holding it in place.

Step 4: Press and hold the power switch for 3 seconds to engage suction, then release the robot.

- Cleaning Cloths: The microfiber cleaning cloths are reusable. After each use, remove them from the robot and wash them thoroughly. Ensure they are dry before reattaching.
- Spray Nozzles: If a nozzle does not spray water due to accumulated dust or impurities, gently poke it with a thin needle to clear the obstruction.
- Water Tank: Empty and rinse the water tank after each use to prevent residue buildup.
7. Troubleshooting
Refer to this section for solutions to common issues.
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot alerts "insufficient water" despite full tank. | Purified water used instead of tap water. | Replace purified water with clean tap water. |
| Robot cannot be turned on. | Not plugged into a power source; insufficient initial charge. | Ensure the robot is always plugged in during operation. For first use, fully charge the internal UPS battery for 40 minutes. |
| Nozzle does not spray water. | Accumulated dust or impurities in the nozzle. | Gently poke the nozzle with a thin needle to clear the obstruction. |
| Cleaning performance is not satisfactory (e.g., streaks). | Heavily soiled glass; dirty cleaning cloth. | For extremely dirty glass, use multiple cleaning modes and frequently change the cleaning rag. Perform multiple passes. |
| Robot does not clean window corners. | Inherent design limitation. | This is a known characteristic of robotic window cleaners. Manual touch-up may be required for precise corner cleaning. |
