Bests & Worsts Reviews from Amazon

This Roomba never like a first generator. Look good technology but is not working properly. At 4:00 a.m start a noise like a finish work. Then do not working or cleaning, using manual or Apps. The noise lasted after one hour. Also the edge brush damage so early. The IRobot company describe a edge brush to replace after 3 month, but its not a really. Only work two clean and brush damage. In overall, this machine is a waste money. Its a lot expensive over $1,200 and Roomba old version working much better and cost $250 to $350. I'm so disappointment and upset with this product.
