My rob has issues when working a room with bright corners. It would stay around a bright spot (about 1 square metre) for more than half an hour. Is there any settings in the app I can adjust?
No. There is no setting for this.
@NiclasK, how should I deal with it?
You can block of those corners and let the robot finish cleaning the room. In the Floorplanner you can make zones in the area you want to clean and leave out the corners where it have problems cleaning. Schedule a zone cleaning.
If the bright corners are from windows, cover them. Or try to clean at a different time, when it is not bright.
