Forces to remove cords, ropes, light shoes from the floor. Mine loves to get stuck on the leg of a clothes dryer. That's right, as soon as it turns on, then immediately straight to the dryer and the war begins. As a rule, the dryer wins. He does not clean near the base, he goes around for a meter. Only for small rooms (up to 50m²). Its pros: Inexpensive. Good battery life, more than an hour. "See" steps down. There is a cloth that wipes the floor and which can even be wetted. Spare pair of brushes and Hepa filter included. Has some cons The base slides on the floor, I had to glue it with tape. Noisy. It takes quite a long time to remove, because it does not build a map and moves along a chaotic trajectory. Sometimes makes small gaps. From time to time "butts" in multi-colored borders of a covering. Once a year, you have to disassemble and wipe the sensors from dust because it starts to "fool".
