Good day Driftar1942,

Unfortunately you cannot demarcate the areas on the map itself, as David correctly explained, you can do this with the virtual walls.
You can test whether the Roomba 960 gets stuck on your chairs thanks to Buy&Try.
If you are not satisfied, you can return the Roomba 960 to us.

Thank you and best regards
Your iRobot Team

Unfortunately not on the map itself. But you can mark out areas with virtual walls (https://www.galaxus.ch/de/s2/product/irobot-roomba-dual-mode-staubsaugerzubehoer-5719428) where the Roomba is not allowed to go through.
I'm not really happy with these walls, though, because they have to be placed and switched on and off every time.

PS: Unfortunately, I also have the problem with the dining room chairs with the Roomba 960. I put the chairs on the table when I run it, with the nice side effect that it also cleans under the table ;).

Hello, and thank you very much for your answers. It's certainly on the shortlist. Personally, I find the virtual walls too cumbersome. I would have to put up several such walls for the dining room table and its chairs, and they would be in the middle of the room, which is not exactly ideal.

But who knows, maybe such a function will come with a firmware update. It should be technically feasible, the map exists, and the vacuum cleaner also has a navigation system inside ;-)
