Robot vacuum emits a high‑pitched squeal when the main brush is spinning.

Safety first: Turn OFF the robot before removing the main brush.

• 1. Remove and clean brush: Take out the main brush and remove hair from the bristles and ends.
• 2. Clean end caps: Remove the end caps (if removable) and clear any hair or dust from inside. Wipe the shafts with a dry cloth.
• 3. Inspect bearings: Check for visible wear or damage on the brush ends. Replace the iHome main brush if bearings are worn.
• 4. Check brush cover alignment: Ensure the brush cover is not warped and that it snaps down evenly.
• 5. Test noise: Reinstall the brush and run the robot. If squealing persists, inspect the main brush motor assembly for bearing noise and replace if necessary.
