As others have said, tidying and cleaning are quite different things. Most cleaners will come to do the latter. If your house is untidy, it makes their job harder.

You can get a person in to tidy up for you, but it’s usually a different person than the cleaner, and that requires much more input from yourself “Where does this go? Where do you want this? Do these clothes need to be folded or washed? Is this trash or not?”.

Anyway. Yes I’ve definitely been guilty of tidying the whole house before our cleaner comes.
