My raised beds are between 200-800mm (2-3' for the highest ones) - I'd need quite the slopes for most of them!
Roombas do, it would be weird if this new iteration didn't
Roombas have to deal with stairs while this thing will probably get it's underside covered in mud (especially since it has that unshielded trimmer) and is supposed to run only inside a fenced area, so I doubt it has any provisions for that.
