The robot misses an area.

1. The robot cannot enter the narrow space unless it is 2 cm wider than both sides of the robot.
2. For the robot with the ultrasonic sensor, it can recognize the carpet at the door and will not enter this room while mopping. Please remove the carpet.
3. If some zones are overlapping on the map, the robot may fail to self-position and miss some areas while cleaning. If so, re-map the areas to be cleaned or restore the map.
4. If there is a high pile carpet or wires at the entrance of the area to be cleaned, the robot with the obstacle avoidance function will avoid this area. Please tidy up the items on the floor before operating the robot.
