Why the Xiaomi Robot Vacuum T12 fails to recharge ?

There are too many obstacles near the charging base. Please place the charging base in an open area and ensure that there are no obstacles within 0.5 meters on both sides of the charging base and 1.5 meters in front of the charging base.
The host did not start from the charging base before cleaning, and the charging base was not found during the cleaning process. Please try to make the host start from the charging base to clean.
The host was moved during the cleaning process. When cleaning was continued, the relocation of the host failed and a new task was started.
