There are mopping robots, I have a Braava by irobot
Be warned: that specific model (M6) cannot clean the inside of corners! I’m sure there are newer (and nicer ones) that can do that, since irobot has been super behind the curve for a long time
On the other hand there are now combo vacuum/mop robots but idk if those mop corners very well since I don’t have one
