Wyze robot vacuum displays C13 and stops; often indicates a low battery or charging protection error.

Safety first: Inspect the robot and dock for signs of overheating or burning smell. If present, unplug immediately and do not use.

• Clean charging contacts: Wipe the metal contacts on both the robot and the dock with a dry cloth. Remove any oxidation or debris.
• Ensure proper docking: Place the robot on the dock manually, making sure the contacts align and the charging indicator in the app or on the robot lights up.
• Allow extended charging: If the battery is deeply discharged, leave the robot on the dock for at least 4–6 hours without interruption before attempting to start a cleaning cycle.
• Check power source: Verify the dock is plugged into a working outlet and the power adapter is firmly connected.
• If C13 remains after full charge: The battery pack may be failing or the charging circuit may be defective. Replacing the battery is a moderate repair (remove bottom cover and battery compartment). If a new genuine Wyze battery does not resolve the issue, the main board may need service.
