Solution:
1. Check whether the Robot Vacuum cannot reach the cleaning area due to obstacles;
2. Check whether the cleaning is incomplete due to changes in the placement environment of the items in the cleaning area;
3. Check whether some areas cannot be cleaned due to changes in virtual wall settings;
4. If a single room is not cleaned, whether the door is closed after the machine is built due to the change of the door opening and closing, and the room cannot be entered without completing the cleaning.
