Robot construction is confusing /missing?

The map is confusing : please try to use the previous correct map; please try to restart the robot and rebuild the map;

Lack of map construction: Please ensure that the passages of all areas to be cleaned are unobstructed when the robot builds a map, and organize the wires and other items in the home to ensure that the robot can walk smoothly. If the door of a room is closed while the map is being created, the next time the robot cleans, the door of this room is opened, the robot will enter automatically, and the map will be updated automatically.
