Setup
- Charge the Backup Power: Ensure the robot's internal UPS (Uninterruptible Power Supply) system is fully charged before use. Connect the power adapter to the robot and a power outlet. The indicator light will flash red during initial charging and turn green when ready. This backup power prevents the robot from falling in case of a power cut.
- Attach Safety Rope: Securely plug the safety rope into its designated port on the robot. Attach the other end of the safety rope to a sturdy anchor point capable of holding the robot's weight. This is crucial for safety, especially when cleaning exterior windows or at heights.
- Attach Cleaning Pads: Place the appropriate cleaning pads onto the robot's cleaning surfaces. For initial cleaning of very dirty windows, use the grey pads. For polishing or less soiled windows, use the yellow pads. Ensure the pads do not cover any sensors or the fan opening.
- Apply Cleaning Solution: Lightly spray cleaning solution onto the cleaning pads. Avoid oversaturating the pads, as this can reduce suction and leave streaks. For optimal results, spray only the edges of the pads, or directly onto the window surface in moderation.

Operating Instructions
- Power On: Press and hold the power button on the robot for a few seconds until it powers on and the indicator light turns blue.
- Place on Window: Carefully place the robot onto the window surface. Ensure it adheres securely before releasing your hand. The robot's vacuum pump will create suction to hold it in place.
- Select Cleaning Mode: Use the remote control or the mobile app to select your desired cleaning mode. The robot features intelligent planning for efficient cleaning routes, detecting edges and avoiding obstacles.
- Monitor Progress: The robot will automatically clean the designated area. Monitor its progress and ensure the safety rope remains secure.
- Finish Cleaning: Once cleaning is complete, the robot will return to its starting position and emit an alert. Press the power button to turn it off and carefully remove it from the window.

Maintenance
- Cleaning Pads: The cleaning pads are machine washable. After each use, remove the pads from the robot and wash them. Ensure they are completely dry before reattaching them to the robot for future use. Wet pads can affect the robot's suction and performance.
- Robot Body: Wipe the robot's body with a dry, soft cloth to remove any dust or residue. Avoid using abrasive cleaners or solvents.
- Sensors and Wheels: Periodically check and clean the edge detection sensors and wheels to ensure optimal navigation and performance.
Troubleshooting
- Robot not adhering or falling:
- Ensure the power cord is securely connected and the backup battery is charged.
- Check if the cleaning pads are too wet. Over-saturated pads can reduce suction. Ensure pads are dry or only lightly dampened.
- Verify the window surface is at least 3 mm thick.
- If the window is extremely dirty, the robot may struggle to maintain suction. Pre-clean heavily soiled areas if necessary.
- Streaks left on window:
- The cleaning pads might be dirty. Replace with clean pads.
- Too much cleaning solution may have been applied. Use less solution.
- The window may require a second pass with fresh, dry pads for polishing.
- Robot not moving or stuck:
- Check for obstacles on the window surface.
- Ensure the power cord is not tangled or obstructing movement.
- The smallest area the robot can clean is 45 x 45 cm. Ensure the window size meets this requirement.
