Bought my XV12 from home.woot 2 weeks ago. I live in an apartment that is hardwood in the kitchen and living room, tile in the bathrooms, and low pile carpet in the bedrooms. I set it for 2:00pm everyday. I have a 60 pound dog that sheds as if she hates her own hair. I mean this dog SHEDS.
I will agree with those that said it will get stuck. That said, if you watch it the first couple of times, you can find WHERE it will get stuck. Do that, and then you can appropriately block those areas or change the set up. I have two things in my house that it will get stuck under. They seem to be the perfectly wrong height, meaning Neato can start to get under them and then can't get out. I blocked both with the black/brown magnetic strip. The poster who said they need to be taped on hardwood is 100% correct. Neato will just push it around otherwise. On carpet, as he said, no need to tape. I run it every day and the container is FULL. It grosses me out to think what I was missing before.
Now that I have things figured out, it has gone 8 days without getting stuck.
One bonus to it, is that one of its limitations has made me keep my apartment cleaner. I know the thing will not clean properly if there are things on the floor (or it will try to eat them). Knowing this makes me sure there isn't crap laying on my floor. My hampers, and my wife, have never been so happy. So, my advice? Buy one. Clean crap off your floors before you leave, and be at home the first couple of times so you can see where it might get stuck and plan accordingly.
