Troubleshooting tips:
1. If the robot shows an error code, please restart the robot first and check whether the issue is resolved.
2. Mode Setting: Make sure the cleaner is in “Wall” mode and not in “Floor Only” mode.
3. Battery Level: Low battery (<30%) restricts the cleaner to floor mode.
4. Tracks, Roller & Impeller: Inspect the tracks, roller brush, and impeller for debris, blockage, or wear (visual inspection only; disassembly is not required). Also make sure the charging port cover is fully inserted and properly sealed.
If all the above settings and conditions are correct, please try the following steps:
1. Clean the filter thoroughly. If available, use a high-pressure water hose for thorough cleaning.
2. Check firmware updates
If the issue continues, please provide:
1. A short video showing the cleaner’s behavior.
2. SN and Virtual ID of your cleaner
3. Confirm the location: whether the robot fails to climb all walls or only specific areas of the pool. (This helps us better if you're willing to share your pool information or send a full pool photo)
