The vacuum cleaner does a good job of cleaning very quickly. The structure works as follows: 1. Get the Xiaomi Home app. 2. Install it. After that, the vacuum cleaner will analyze the space and produce a map. 3. After that, you section off different areas on this map. 4. After that, you will be able to tell the vacuum cleaner which regions it is responsible for cleaning. After then, he personally responds to the directive by returning to the charging zone. Comfortable. One criticism is that the app's overall performance is painfully slow. It takes a very long time for rooms to load. Does not always comply when given instructions. Based on what I've read, this seems to be a rather widespread issue. But all things considered, it's a really handy item to have!:-)
