Xiaomi mi robot vacuum mop essential, MAP

  • Hello.
    So iv gotten this new "smart" vacum I wanted to try. One thing thats a bit strange is the map it makes.

    1. I was wondering, does this map the room and actually use the map later, or is it just for show to see what its doing? Is it learing at all, and can find rooms later runs?

    2. Any easy way to reset the map?

    3. IV checked the app but cannot find any virtual walls for this unit, guessing it doessent have it. Any easy tips to stop it from goint into some ope doors?
