How to Fix / Troubleshooting

Safety first: Place the robot on a flat, hard floor and turn it off.

Check wheel travel: Press each drive wheel up and down. They should move freely and return under spring tension.
Remove debris: Clear any hair, threads, or objects from around the wheel arms and suspension.
Restart on flat surface: Turn the robot on without touching or lifting it and allow it to complete its startup.
Test cleaning: Start a cleaning cycle and observe if the error reappears when the robot climbs thresholds or rugs.
Service if needed: If E17 persists, the wheel lift sensor or suspension assembly may be damaged and require replacement.

Warning: Do not carry the robot while it is starting up or calibrating; this can confuse the lift sensors.

Robot vacuum shows E17 and cannot start; often associated with a stuck or locked wheel height sensor on some models.
