If the Xiaomi Robot Vacuum X20 Max cannot be charged normally, follow these steps to troubleshoot the issue:
1. It takes about 6.5 hours to charge the Xiaomi Robot Vacuum X20 Max from low to full power. Please wait patiently;
2. 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;
3. Please wipe the charging spring and the charging electrode with a dry cloth;
4. Ensure the omni station is plugged into a working power outlet. Check the outlet with another device to confirm that it is functioning;
5. Check for any visible damage or loose connections on the robot vacuum or the omni station. Examine the charging cable for any signs of damage or fraying;
6. 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.
