I'm a fan of the roborock S8 (now the S10 i guess)

It's a vacuum + mop combo which imo is way better for hard floors

Does it choose based on the surface, or just let both run all the time? (Mop on carpet doesn't sound ideal)

They have an ultrasonic sensor to measure the type of floor and will not pump water when carpet is detected
