This is my first robot. For a long time I chose between manufacturers (between those who do everything in a row and those who deal exclusively with robots and smart home), read reviews. I came to the conclusion that a good vacuum cleaner and a robot in one box worth $ 200 cannot be of high quality and fully meet expectations, you will always sacrifice something - either the quality of cleaning or ease of operation. You have to spend a little more. But you won't regret it. It will work and please you, and not stand in a closet and make you think who would fuse it. Very happy with the purchase. Under the bed is now clean every day. Neither a mop nor an ordinary vacuum cleaner can get there. It's worth it
