Possible Causes
Internal IMU (gyroscope) calibration fault, Strong magnetic or metallic interference, Loose navigation sensor connector, Defective IMU module on mainboard
How to Fix / Troubleshooting
Safety first: Turn the robot OFF and move it away from metal furniture bases, speakers, or large appliances.
- 1. Reboot and recalibrate: Power the robot OFF for 30 seconds, then turn it ON. Some Bosch models perform an automatic sensor calibration at startup; keep the robot on a level surface during this time.
- 2. Clear environment: Remove strong magnets, large metal objects, or electronic devices from the immediate cleaning area and retry.
- 3. Check for firmware updates: Open the Bosch Home Connect or Bosch robot app and check for available firmware updates that may address navigation issues.
- 4. Factory reset (if available): Follow the user manual to perform a factory reset, then re‑add the robot to the app.
- 5. If E08 persists: The internal IMU or navigation board is likely faulty. This requires mainboard or sensor module replacement by an authorized Bosch service center.
