When you move your T8/ T8+, or manually turn it off/on, the robot needs to relocate its position on the map; if the positioning fails, the map on the main interface will be lost and a new, temporary map will be created.
Your T8/ T8+ will generate a map when doing the very first cleaning task. If you move your robot during this map generation process and then trigger cleaning, the robot will try to position itself. If the positioning fails, it will restart the cleaning. In this case, the original map will be lost and cannot be restored. Please let the robot complete the cleaning and automatically return to the charging dock to save the map;
If you move T8/ T8+ and then trigger cleaning when the map has already been saved, the robot will try to position itself. If the positioning fails, it will restart the cleaning.
To restore the map: You can carry your T8/ T8+ back to the charging dock if you want to restore the map immediately.
