Very hard to get the remote to sync with the vacuum. Does not clean all the area!  Goes in a very very random pattern, including the waffle pattern.  There is no mapping that you can see where it has been or not been.  Has a horrible time returning to its charging station if it is in another room.  We have a two bedroom, two bathroom apartment that has 1200 square feet and it cant clean it in one session.  It consistantly repeats what it has already gone over instead of finding new carpet in the same area to clean.  Does not do edging very good, unless you set it up for walls only.  Definitely returning this one, thankfully I didnt pay full price!
