So far so good.  This is helping cut down on the pet hair tremendously!  We have two (large) dogs, 3 cats, and 4 children so the pet hair and dust is always being kicked up.  I have to empty "bob", twice a day but it does the job well.  I also love that you can set it on a schedule and it will clean while you are sleeping or not home.  The UV light is a very cool addition to sanitize the floors.  So far I am very happy with my purchase.
