. What I don't like is that it doesn't vacuum the whole room. It moves in one direction until it bumps into something, then turns and moves at a 90 degree angle in the other direction. That's why he has no intelligent pattern, half the bottom is missing. It was more like babysitting a robot. Sometimes gets caught under furniture or power cords. I could never leave this vacuum cleaner unattended. It could be in a room with no furniture. It never docked, ever. I haven't even used a mop. If he's not good at vacuuming, how can he mop at all?
