There are probably some exceptions. I can imagine robo lawnmowers getting good enough to handle my yard at some point if not adjacent cleanup. But doing a monthly housecleaning? Don't think so. (And a Roomba really wouldn't be very useful; it's barely useful at my brother's house that is practically built for a Roomba.)
However, houses and things inside it were designed by humans for humans, for either aesthetic or 'easy for humans to do' reasons. I sometimes wonder then what if they were designed from the ground up with let's call it 'robot repairability'/automation in mind. I don't know exactly what that looks like, but I'd imagine a lot more modular, a lot more brutalist/uglier, and probably a lot more expensive. But it's an interesting thing to think about nonetheless.
They will need help doing the finer control things, and they won't do everything. But definitely useful enough, especially for older folk.
Chinese tech has come a long way in the last 5 years. Roomba just went bankrupt for a good reason.
