Possible Causes
Obstructed LIDAR turret, Dust on LIDAR window, Stuck LIDAR motor, Failed LIDAR sensor module
How to Fix / Troubleshooting
Safety first: Turn the robot OFF before touching the LIDAR turret. Do not look directly into any laser aperture.
- 1. Inspect the LIDAR turret: On mapping-capable Electrolux models, locate the rotating turret on top. Ensure nothing is resting on it or blocking its rotation.
- 2. Clean the LIDAR window: Wipe the transparent cover of the turret with a soft, dry microfiber cloth to remove dust and smudges.
- 3. Check for free rotation: Gently try to rotate the turret. It should move smoothly with slight resistance. If it is stuck, check for trapped debris around the base.
- 4. Reboot and test: Power the robot back on and start a mapping or cleaning run. Listen for the faint whirring sound of the LIDAR motor.
- 5. Internal inspection (advanced): If the turret does not spin, open the top cover (if serviceable) to access the LIDAR module. Verify the motor and sensor connectors are secure.
- 6. Replace LIDAR module: If E12 persists and the LIDAR does not operate, replace the complete Electrolux LIDAR sensor assembly.
