Astonishingly well designed and powerful. The only thing is that this particular one has an intermittent short if used on heavy carpets. I'm returning it for another, but otherwise, very impressed. I vacuumed my entire apartment, sat down, got up and did some more. Sat down and kept thinking, "what else can I vacuum?"
Works so effortlessly, almost makes sweeping fun! We have a retriever and hair ends of under furniture on the hardwood floors. This easily gets under the furniture and can clean the cushions on top. Really love it, best Mother's Day present to myself ever!!!! Would buy again and would definitely recommend to a friend!
