I have a Roomba with a camera. It navigates very well, including figuring out where it’s at within seconds of being manually moved to a new location on a different floor.

I too have a Roomba with a camera (the 980) and I am mostly satisfied with it (after ten years I guess I got used to its quirks).

I have also recently set-up the LIDAR-equipped 705 for my parents and let me tell you, there is no comparison.

The navigation speed is greatly improved which means cleaning tasks take a lot less time. Furthermore, it works in complete darkness with no problems! The camera-equipped model just bumps into stuff randomly and then gives up when it's too dark.
