I haven't tested it, but the basic impression is that nothing really works without Wi-Fi. Apart from pressing the start button and cleaning. I turned off the Wi-Fi and the vacuum at night for a while - a huge derby every time until it reconnected. Basically, it's a brilliant device, but it reacts sensitively to manual intervention. It would probably prefer a flat without thresholds, which it can clean independently (and in permanent consultation with the Xiaomi Cloud). For example, if I carry it from one room to another (because of the thresholds) and then have it clean, it sometimes forgets the map of the entire flat because it is so scared...
