How to Fix / Troubleshooting
Safety first: Turn OFF the robot before cleaning sensors.
- 1. Clean front sensors: Wipe the dark plastic windows on the front of the robot with a soft, dry cloth to remove dust and fingerprints.
- 2. Test in a simple environment: Place a solid object (like a box) in front of the robot and start cleaning. Observe whether it slows down before impact.
- 3. Check for physical damage: Inspect the front housing for cracks or misalignment that might affect sensor alignment.
- 4. Advanced repair: If E17 remains, the front IR sensor board may need to be reseated or replaced. This involves opening the front housing and reconnecting or swapping the sensor PCB.
