I like this "little" guy. He does a good job mopping up floors. However, he doesn't seem able to clean around the comode in the bathroom. He cleans wooden floors and tile floors pretty good. But if you are a real "stickler" for cleanliness, this robot is not for you. He doesn't get into the corners very well, nor does he get over floor "lips" going from room to room. But he's good for what I need.
