I have a similar experience as the OP. I got a vacuum robot (Roborock) and it does work like advertised. Vacuum and mop works so well that I almost never to mob my house manually anymore.
3rding the recommendation. I have an S6 and it actually cleans unlike my old shark. It sucks up all the cat hair and does a decent job at maintenance mopping. It's much smarter too. It doesn't just battering ram everything until it finishes a floor. It can operate in the dark so I have it clean the living room at night when we're all asleep. It's an incredible machine.
For privacy conscious people, you can mod these things with firmware that keeps everything local.
