What to do if the Xiaomi Robot Vacuum H40 cannot return to the auto-empty station properly?

If your Xiaomi Robot Vacuum H40 is unable to return to the auto-empty station properly, please follow these steps to troubleshoot:
1. Ensure the power cable is securely connected at both ends and the auto-empty station is receiving power properly without any interruptions;
2. Check if the auto-empty station is placed flat against the wall on a hard, level surface, with no obstacles within 0.5 meters on each side and 1.5 meters in front to allow proper navigation;
3. Inspect the charging contact on the auto-empty station. If they appear dusty or dirty, gently wipe them with a dry cloth to ensure good contact;
4. Restart the vacuum and manually place it near the auto-empty station to see if it aligns and charges successfully.
