Yes. They build a 'map' of your floor and obstacles the first couple of times they go to work on your floors and on your instruction. In fact, in the app on your phone, you can tell it which 'maps' to work on. If you only want the kitchen and hallway done, tell it to use Map B.

Some models do very well with dog hairs, and they all know how to move around chair legs, cassocks, side-tables, etc. What they will have trouble with, but only in figuring out how to deal with the new obstacle, until they include it in the map, is anything large that you leave in the map that wasn't there the previous mapping...like a laundry basket, or a moved garbage can.
