I have mapped the house with my new Roborock Q Revo and there seems to be one area that is cut off from the map. I attempted to do a zone clean where the door leads to the hall and the robot seems to think that doorway was completely cut off/blocked even through it was wide open. It would not cross into the area.
I ran it in there with the remote control function hoping it might map but it did not. Next I'm going to attempt a FULL clean to see if it ventures in that area.
