Why does the DEEBOT T9 miss some rooms when it cleans?

Updated on 2021/04/02
(1) The room's threshold is over 20 mm, which is taller than DEEBOT's obstacle traversing capacity. DEEBOT must be manually moved into the room to be cleaned. After DEEBOT has finished cleaning, move it back out of the room and the deebot will continue cleaning the other rooms.
(2) Check whether there is dust in the TrueDetect 3D Smart Detection System. If there is, wipe it gently with a dry paper towel.
(3) A complex environment or a high threshold or mat in the doorway may be mistakenly identified as an obstacle by the TrueDetect 3D Smart Detection System, and the DEEBOT will not enter the room to clean. The user may move the mat or disable the TrueDetect 3D Smart Detection function in the App settings.
(4) In Mopping mode, the TrueDetect 3D Obstacle Detection and Avoidance System will avoid some areas with high thresholds, to make sure the robot can keep cleaning without running into problems.
(5) If the door threshold is higher than the level that DEEBOT can cross, there will be a notification in the App (later OTA). You can move DEEBOT to the desired area to begin cleaning, but before moving DEEBOT, make sure you have created and saved the map, otherwise the map may be lost (since DEEBOT has not been to the area before, it is completely new territory that DEEBOT has no memory of, so there is a chance that relocation could fail, causing map loss).
