How to Fix / Troubleshooting
Safety: Turn the robot OFF.
- Clean front sensors: Wipe the front-facing IR sensor windows and wall-follow sensors with a soft, dry microfiber cloth.
- Check for damage: Inspect the clear plastic lens area for cracks or heavy scratches that could distort readings.
- Reduce reflections: If possible, move highly reflective objects (mirrors, chrome furniture) away from the robot's path during testing.
- Reboot and test: Power the robot back on and run a short cleaning cycle.
Persistent E6 after cleaning suggests a failing front sensor board that may require replacement.
