The meaning of “Broom Cleaned”

Broom clean is a real-estate term used to describe the condition in which  a renter must leave a home.

The rules for vacating a rental are quite strict: Broom clean means you should leave the place in the same condition as when you moved in, minus reasonable wear and tear. So once you’ve removed your belongings, have the carpets professional cleaned, and break out a broom, Swiffer, or other cleaning weapon of choice and go to town.
