If your Xiaomi Robot Vacuum S40C is unable to return to the charging dock, it can be caused by environmental factors, positioning issues, or power connection problems.
If the robot vacuum fails to return to the station or recharge, please refer to the following solutions:
1. Ensure that the charging dock’s power cable is securely plugged in and that the power outlet is working properly, as the dock cannot function without power;
2. Inspect the spring contacts on the charging dock. If they are dirty, wipe them clean and try again;
3. Make sure the signaling area on the charging dock is not blocked by objects or covered in dust, which can prevent the robot from accurately locating the dock;
4. Check the robot’s sensors and navigation. Dirty sensors or outdated map data can lead to docking failure. Clean the sensors or reset the map if necessary;
5. If the above methods do not resolve the issue, please contact the local after-sales service center.
