I bought this vacuum cleaner for my aunt. She had just redone her floor and made sure to keep the floor clean. I bought one a few months ago and it's still doing its job well around the house. This version has a low profile and is designed to fit under sofas. With the remote you can change the pattern it follows or just let it wander. Be sure to remove the included styrofoam underneath or it won't roll over when hitting obstacles. Judging by the photo, gained a lot. I am happy with mine and my aunt is very happy with it. Highly recommended. Works great and the price is reasonable.
