I have wood floors and it works great. It's quiet and just runs around house doing its job. Will be getting one for my daughter and one for my girlfriend. Can't beat the price or quality. Highly recommend it you have tile or wood floors. I bought the Haier and it was under 100 dollars
Maybe I just got a "bad" one......but this robot had major trouble with any obstacles, and the front bumper fell/broke off after only a 2nd time using. I wouldn't recommend.
