Both have their pros and cons. Dust mops (especially the microfiber types) can stick to dust, dirt, and debris and help you clean your floor more effectively. They’re useful for cleaning up messes that a broom would push out into the air. Dust mops are also especially helpful for cleaning pet hair. A broom pushes dirt and debris around. Unlike microfiber dust mops, they don’t “soak” up debris. As a result, brooms can deal with big messes better.
