Bests & Worsts Reviews from Amazon

I don't think IRobot should sell something like this that does work as advertised. It was my second roomba and took 3 minutes to get off the dock, ran for about 15 minutes and returned to dock. I tried it again and it only did half of my living room and never left the room. It was fully charged as I charged it overnight before using. I guess you have to purchase a better model to get a good job. Very disappointed!
