When the map is finally ready, you need to finish setting it up. First, you give the map a name, like “our apartment,” or “downstairs,” or whatever you want— “Narnia” would be acceptable. Then, you need create “room dividers” on the digital map. These are green lines that you can adjust to separate rooms for the Roomba to know what space is what. For example, I divided a long hallway into two portions, then labeled one simply “hallway,” and another “entryway.” Other rooms are labeled in straightforward ways: living room, kitchen, master bedroom.
