Malfunction phenomenon

The   map is lost.

Troubleshooting

1.   Check whether the firmware version is the latest, and update to the latest   firmware version.

2.   Confirm that the user’s map is saved successfully (if the area cleaning can   be used, it is saved successfully).

3.   It is recommended that the user rebuild the map and save the permanent map.

4.   After saving the permanent map, the user can clean again and check the map.

①If   the map still exists, the robot is good.

②If   the map is lost, please re-create the map. At this time, turn off DEEBOT and   restarted it to dock the charging dock, and get back the map.

Maintenance Plan

1. If the malfunction can be   stabilized at the outlet, consider the D-TOF malfunction.

2. If it is invalid to replace   D-TOF, and the malfunction persists, please replace the mainboard.
