I don’t have cleaners. But the last time I saw this joke made a commenter opened OPs eyes with something along the lines of:

Imagine hiring cleaners gives you a +2 to your cleanliness level.

You start at 5. +Cleaners: 7

Clean first to get to 7 on your own? +Cleaners: 9

Also. Cleaners will start with the easy shit like dishes. If dishes are done they have to go deeper to clean harder shit. Get your money’s worth.
