Robot vacuum stops shortly after starting and displays E2; main side brush does not spin.

Safety first: Power OFF the robot and remove it from the dock. Flip it over on a stable surface.

• 1. Inspect the side brush: Check for hair, string, or cables wrapped around the side brush hub. Remove any obstructions.
• 2. Remove the side brush: Use a small Phillips screwdriver to remove the screw in the center of the side brush (if present). Lift the brush off the motor shaft.
• 3. Clean the motor shaft: Remove hair and dust from around the shaft. Ensure the shaft can rotate freely by turning it gently with your fingers.
• 4. Check for physical damage: If the side brush is warped or cracked, replace it. If the shaft wobbles excessively or feels rough, the motor/gearbox may be damaged.
• 5. Reinstall and test: Refit the side brush and screw. Power ON the robot and start a cleaning cycle. Observe whether the side brush spins normally.
• 6. If E2 persists: The side brush motor module or its wiring harness may be faulty. Access typically requires removing the bottom cover and disconnecting the motor from the main control board. Replace with a compatible Amazon Basics side brush motor assembly or seek professional service.
