I hear you. I have a mixture of carpet, tile, hardwoods, and stairs. I would pay $600 or $700 (reluctantly, mind you) for a vacuum that would handle all those things well, but I don't think that would begin to get me anything decent.
Got a shark that we use for most of the house and a roomba that I use in my office. Shark is good for tile and hardwood. Keeps the pet hair in check during the week very well. Roomba we have is a cheaper model and it gets stuck to easily. I use an upright vacuum about once a month in my office as Roomba is just okay on carpet.
I’ve been thinking about getting the Roborock S7 MaxV Ultra seems like the best one on the market based off my research
I wouldn't use it for carpet if you have pets, bin gets full waaaay too fast. Does fine on hard surfaces. I have a Roomba by the way. I think I've had it for 3 or 4 years now. Never had issues with it.
I have a roomba I use for my bedroom/bath/closet and use it once a week mainly to control cat hair and it does ok.......cleaning it out becomes a pain but not a deal breaker. I like the fact I can turn it on and walk away
