My particular Roomba does not have cameras. It was a deciding factor in my decision of which model is right for me. There are other features that were originally only available on the models with cameras like being able to map a floor plan and then telling Roomba which specifi room to clean. However, a few months ago, a software update provided that feature to my model as well. I have to send it on a specific mapping routine, but I just hadn't gotten around to doing it. I probably won't ever now.
