They are OK. My wife puts it in different rooms while she is doing other cleaning. It does a surprising good job vacuuming the floor and it gets under beds etc, that we'd normally not vacuum that often. As noted earlier, customer service is good as we had a part break in the first month. Cons- it can fill up fast if you have a dog (we have a black lab)that sheds constantly. The filters get clogged fast too and you have to clean them. They are not really quiet and I am pretty sure I can vacuum my house manually A LOT faster. If it were up to me, we would have taking the thing back after the first use and taken the cash I think it would be great for a small apartment with no pets.
