The language of the robot hoover can usually be changed via the associated app or the device settings. For Xiaomi products such as the MI Robot Vacuum S12, the language is often customised via the Mi Home app. If you want to change the language to German, you can search for the language settings in the app and select the desired language. If the language cannot be changed or remains in English, it may be helpful to update the app or check the device settings.

Yes, the Xiaomi MI Robot Vacuum S12 can map and save multiple floors. The laser navigation technology allows the robot to create accurate maps of multiple floors and save them for later reuse. You can therefore use the robot on different floors by carrying it to the other floor and using the previously saved maps.

Look on google and enter: "Xiaomi S12 MI Filter" there are some China suppliers like Th... or Swiss Apfelki.... ... free choice. Xiaomi is a Chinese brand, so don't worry 😉

When you press the start button, it goes through everything and vacuums. As the thresholds between the rooms are so high that the robot can't get over them, we vacuum room by room. We do it exactly the same way, place the robot in the room, close all the doors and press the button. It then vacuums the room. We never need the app. But we don't use the wet pick-up function. I'm no longer sure whether you need the app for that.

No. only 2.4 ghz

Yes you can. I also have a threshold in the bedroom and I put it in there and start it and it vacuums the room without any problems and announces itself as soon as it's finished.
