I can add that I recently bought 3 different robot cleaning systems. Two are floor mopping/vacuum robots and the third is a window cleaning robot. The latter takes some supervision but does a more than adequate job on large windows and we have several that are 20 feet high so this is a godsend. The floor robots are interesting. I have a Xiaomi Mop plus and it works great. Once it memorizes your floorplan (takes 3 uninterrupted cleaning cycles) then it works great. The mop function is really just a rag that damp mops the already clean floor. It works pretty well especially if you use distilled/deionized water. The other is a Neatsvor Mopping robot which is similar to the Xiaomi. The Xiaomi will mop and vacuum simultaneously but the Neatsvor does it separately. Both use laser guidance and create excellent maps.
What I have found is with these floor robots running daily we don't need much cleaning anymore. The windows I do maybe every 2 weeks or so. Each takes about 15 minutes per side to do. Between all of that, we really don't need a housekeeper to come except once every 2 weeks. Maybe when they get real humanistic robots we won't need to do any cleaning at all? I see this is going to come and maybe soon.
I already have a pool cleaning robot that makes that task simple as well and we have had that for 10 years. Many years ago I had a robot lawnmower that worked well for our relatively simple yard back then (it was over 20 years ago). This garden is very complex so I can't see any of the current lawn mowing robots being capable of handling a garden this complicated. But the mulching mower I had mowed the lawn every day so it always looked newly mowed. It wasn't smart and only bounced around o the electronic wire perimeter and/or trees and shrubs. The newer ones are smarter but I think still require installing an underground wire perimeter for signaling the edges. Maybe that will be next if they are smart enough to avoid obstacles and stay out of bedding areas (and swimming pool and large ponds).
I will say we have little strife over cleanliness except I am a very disorganized person and my wife a fanatic for order. I am multitasking and she is a monotasker. But, I am very ordered in the kitchen (as I was in all my laboratories). My man cave/office is another matter entirely and as long as she stays out we have no issues. Her desk area is much larger than mine and roughly 500 sq ft for her and 250 sq ft for me, looks directly into my area (we share the space which is our entire ground floor which is on the main level but considered a basement as it is on a sloping lot) but somehow she doesn't actually see it. I've got all our media servers, router, security system, 3D printers, 4 computers, etc. running in there along with guitars, painting easel etc. plus a workbench crammed with electronics projects, soldering station, microscope, plus 3D print projects in various states of completion. I usually have at least multiple projects in some state of progress (usually waiting on parts or rethinking my approach). Anyway, she seems to have figured out a way to not see any of it. She is very smart! Of course, her area is also nutty as she has 3 computers running and a very large photography studio with backdrops, tables, etc. It is tidy though and I generally stay out of her way. As she is so mono she cannot be interrupted so when she is working I avoid her unless summoned. I was a helicopter pilot for part of my military life and special forces prior to becoming a microbiologist so I can handle many things simultaneously and interruptions are okay for me. We make a good team though as long as I don't irritate her too much. I generally go off during the day mountain biking, hiking, snowboarding, sailing, or whatever to get out of her way. It works well for us.
