5. Maintenance
5.1 Cleaning Cloths
After each use, remove the cleaning cloths from the rotating discs. They can be washed in a washing machine (gentle cycle) but should not be tumble-dried or ironed. Allow them to air dry naturally.
5.2 Chassis Cleaning
Wipe the robot's chassis clean with a dry cloth. For the bottom suction port, wipe it clean with a dry cloth to avoid damage to the product's suction force.
5.3 Nozzle Replacement
If the robot cannot spray water in wet wiping mode, the nozzle may be blocked. Use pliers to gently pull off the old nozzle and replace it with a new one from the packaging accessories.
6. Troubleshooting
- Robot not adhering: Ensure the glass surface is clean and dry. Check for sufficient suction power (6000Pa).
- Uneven cleaning: Replace dirty cleaning cloths. Ensure the water tank is filled.
- Remote control not working: Check the batteries in the remote control. Ensure there are no obstructions between the remote and the robot.
