We have been using this robotic vacuum cleaner for 3 months. Turn on every day to maintain order. He copes well with sand, hair, wool. And even in the corners of the room there is no garbage. The container fills every time. I like that he copes without problems with the rapids himself. The charge is enough for me to clean the apartment (70 sq. M), after each cleaning it goes to the base to recharge. Management is simple. The vacuum cleaner drives itself randomly through the rooms, does not build a map of the room. But the price is good
