When the robot or the Anker eufy app reports error code 2223, 2227, 2230, or 2234 "Side brush stuck. Tap to view cleaning steps.", please follow the steps below.

1. Check whether the side brush is stuck because of tangled foreign objects such as hair or clothing, and clean them out.
2. Check whether the side brush is tangled with fringed or long-pile carpets. If so, set the side brush not to rotate on this type of carpet in the Anker eufy app.
3. After the checks above, run a cleaning task again to confirm that the robot works normally.

If you have any other questions about the S2 Pro, please don't hesitate to contact eufy Support Center for further assistance.
