I bought it for myself, but I had to give it to a retired relative. So there are no maintenance issues. Well, the Xiaomi brand itself is a sign of quality. So I'm ordering again! Got pros: A very hardworking robot. It even climbs into places where it has not been possible to reach since the furniture was installed. Stubborn, if he believes that he has not cleaned it, he washes for ten minutes. He finds his own base. easy to manage both from the application and from the case itself. there are base and cleaning buttons Cons below: It is very inconvenient to open the dust container. Maybe it's because I have extended nails. But still I hope that this is because everything is new and everything will be developed over time.
