We have had the AI Ultra 2-in-1 for about a month.  It vacuums well, we haven't used the mop attachment yet. Set up has been a bit tricky though. I went through the 'learning process' and thought ir completed properly. When it went on its first vacuuming assignment it missed the master bedroom.  I deleted the map and redid the learning  cycle. We placed it clean a second time and it missed the master bedroom again.  Both times it appears to have mapped the house correctly and I labeled the rooms.  Don't know where the problem is.
