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.
This is a fun question to ponder, and you’ll get a thousand different answers from a thousand different people.
I think the more important question (and much harder to find an answer for) is What’s the meaning of the universe? Why does the universe exist? How was it created? Why was it created? What was before the universe was created? What comes after the universe?
And you can join those two questions together. Are the two related? Is the universe’s purpose to create life? Is life’s purpose to experience the universe? Would the universe exist if there was not life to experience it?
