(1) Too much ground clutter, easy to form a class of closed small environment mistakenly triggered alarm trapped;
(2) It is recommended to organize/put away the ground clutter as much as possible before cleaning, especially placing tables, chairs and benches neatly;
(3) It is recommended that after creating the map, use the virtual forbidden zone to avoid the area that is easy to get stuck;
