Update: Have had over a year and still deletes rooms every update.😡 FIX IT! I am turning off auto update and won't be doing anymore udates until I absolutely have to since they can't seem to fix the issue. Original: I gave it 2 stars because it randomly deletes my saved rooms on my map. I keep having to redraw them. Also, I think it fails to communicate to the vacuum when I have only certain rooms selected. Sometimes it does what I want and other times it does not. It is not consistent.
