We've had our bot for about a month now and our floors never looked cleaner. We are an older couple, still living in our large home and vacuuming was something relegated to once a week at best. This bot does an amazing job, gets close to the walls and corners, finds its way around anything, knows not to go down the stairs, it's quickly becoming a member of the family. :)  Seriously though, it's definitely worth the money and you'll wonder why you waited so long.
