What to do if the charging of the Xiaomi Robot Vacuum S40 is abnormal?

If the Xiaomi Robot Vacuum S40 cannot charge properly, please refer to the following steps to troubleshoot:
1. When used in high or low-temperature environments, the robot vacuum will automatically reduce the charging speed to extend the battery life, which is a normal phenomenon;
2. Please check if there is dust on the charging port or contacts of the robot vacuum. Wipe them clean and try again;
3. Make sure there is enough space around the charging dock; otherwise, the robot vacuum cannot dock onto it for charging;
4. Ensure that the robot vacuum is properly aligned on the station.
If the above steps cannot resolve the issue, please contact the local after-sales service center for further assistance.
