How to do if Mi Robot Vacuum appears error 13?

Solution:
  1. If the charging area is not in good contact due to dirt, the charging contacts at the rear of the host and the charging shrapnel of the charging seat should be carefully cleaned.
  2. If the power cord of the charging seat is in bad contact, check whether the power cord is plugged tightly.
  3. The charging base is on uneven ground or the charging base is placed on the carpet. The charging base should be placed against the wall on the horizontal hard ground.
