What to do if the Xiaomi Robot Vacuum S40C can’t reach the designated area?

If the Xiaomi Robot Vacuum S40C cant reach the designated area, please refer to the following steps to troubleshooting:
1. Please check the map list in the Xiaomi Home App. If there are similar or duplicate maps, delete them to prevent the robot vacuum from switching to the wrong map due to re-localization;

2. Confirm whether the LDS laser sensor of the robot vacuum rotates normally. Please try to check whether the LDS laser sensor cover is normal;
3. Please check whether there are foreign objects or hair on the rotating part of the LDS laser sensor, which causes poor rotation or stalling. If so, please try to remove it;
4. Please confirm whether there are uneven or raised stickers or large objects on the surface of the robot vacuum;
5. It is recommended to check and confirm whether the main wheel is entangled with foreign objects;
6. Please try to tap the bumper to confirm that the bumper is in a state where it can rebound;
7. Please wipe the Line laser sensor;
8. Please try to restart the robot vacuum and try again.
