A dust mop is a long-handled mop that is used to dust floors and sometimes even walls, ceilings, and high places. A dust mop is meant to be used dry, and not wet.

Dust mopping is the first line of defense for hard-floor maintenance, when performed regularly and thoroughly with the right tools, dust mopping saves time and money. It extends the life of floor finish, since it removes the abrasive soil which grinds and wears on the floor.
