1. The "split this room" feature does not work on two rooms that have been detected as one. I believe that that is due to the bot not recognising a central chimney as "not room".
2. While cleaning it detects the closed bathroom door as a wall and then does not path into there anymore. As far as I can tell this does not trigger any warning, the bot just drives back into the charging station after some time.
3. The position of the charging station was lost, which made the bot update the map in a weird way, superimposing where it thought it was skewed over the map.
I feel like some of those problems could be fixed fairly easily if users had more control over the SLAM process. I.e. the ability to permanently fix walls in the map.
