So does it do anything better now? I have a relatively new Roomba (one with the camera), and I hate it. Sure it can be more efficient than the old models without a camera, it insists on building an map of the house, which takes forever, constantly needs restarted because it literally can't find rooms, or just fails to update the maps, requiring you to start all over again. It doesn't even have those IR walls, that the old ones had. IF there was a better mapping system, that would be helpful. After like 10 years of trying these things, I've decided they're mostly a gimmick, but damn it, I want them to work.
