Setting up was easy - The Mi App was in English from the outset, and all I had to do was tell it the voice pack should be in English.
I then told it to do a clean, and it spent the next 45mins or so doing the entire ground floor. My concern of it getting from our hallway up a 15mm threshold ramp into our kitchen proved unnecessary as it was no problem at all. Interestingly I started it from a random place yet it still went back to the docking station when finished. It obviously found it on its travels and remembered where!
Note: It doesn't reach/clean right into the corners of rooms, but that's understandable!
Come the end of the clean, the internal collector box was absolutely rammed full! Two things as regards this:-
1) In a review I read, a criticism was that the debris tended to only fill up the middle of the box around the inlet so a lot of the collector box was left unused/empty. This was not my experience. It was filled to all its corners!
2) We wondered what our cleaning lady had done the day before!
My one criticism? The little brush cleaning tool that comes with it... There should be a little slot/home for it under the units lid to keep it in a safe logical place!
