How to Fix / Troubleshooting
Safety first: Turn OFF the robot before cleaning the sensor window.
Steps to try:
- 1. Locate front sensor: Identify the small dark window on the front of the robot used for distance measurement.
- 2. Clean window: Wipe gently with a soft, dry cloth. Avoid scratching the surface.
- 3. Check for cracks: Inspect the plastic window for cracks or cloudiness that could distort readings.
- 4. Test navigation: Power ON and run a cleaning cycle in a clutter‑free area. Observe if the robot still collides heavily with obstacles.
- 5. Replace sensor board: If E18 persists, the front distance sensor board or its cable is likely faulty and should be replaced.
