I bought dreame t20, got mop attachment but better you just mop normally or buy those stick with replaceable/throwaway paper towel.
Can vacuum carpet (deep cleaning usually use almost all battery, and charge take few hours. Normal cleaning carpet maybe a bit lower than hard floor, hardfloor normal runtime 30m, got eco setting for daily use can almost 1h)
Hair tangle less and easy to remove. Easy maintainance. Some part can hand wash, so far no replace anything yet.

Cheaper version would be xiaomi g10, 1k only nowadays. Can say rival dysons. Cons would be expensive parts and less oem. If you only have hardfloor or hard to reach area, maybe fluffy brush better

more manageable size, for cordless vacuum 1k-ish you can get great vacuum, but my experience with those combine mop they don't do great job or replacement pad expensive. Other commenter also mentioned karcher steam mop, that one is good but cord. So my suggestion still cordless vacuum + corded steam mop, good balance of cost and ease of use.
