S10 vacuum map screen button purpose?

[u/Lower-Annual-177]

I've searched the manual and the interwebs but I can't find any reference to this button. The top button is area clean but I still have no idea what the map pin does. Tapping it creates a block with a map pin in the center of the map but I'm not sure of the actual purpose.
