Regular maintenance ensures the longevity and performance of your robot:
- Cleaning Mops: After each use, remove the microfiber cloths and wash them. They are reusable. Ensure they are completely dry before reattaching.
- Water Tank: Empty any remaining water from the tank after use. Clean the tank periodically to prevent residue buildup.
- Spray Nozzle: If water is not spraying, the nozzle may be clogged. Use the included cleaning needle to clear any blockages.
- Robot Body: Wipe the robot's body with a soft, dry cloth. Do not use abrasive cleaners or immerse the robot in water.

The image emphasizes the easy maintenance of the robot, including cleaning the pads and refilling the water tank.
8. Troubleshooting
