I want to love this thing. And for the most part I do, but it gets stuck in the simplest areas. He has no memory at all. it keeps moving in the same direction it's stuck. The battery is wasted. It's fine when going straight, but at the slightest bump it gets stuck in that area and drains the battery. To be honest there will be a good vacuum upstairs where there are fewer road obstacles and where we don't hang around as much, but I'll spend the money and take the "roomba" brand name.
