With a one-two cleaning punch, Swiffer Sweeper is designed to leave your floors up to 3X cleaner than a broom on dirt, dust and hair. Thick dry sweeping cloths conform to the surface of your floors and grout lines, trapping and locking dirt more thoroughly than a broom. Wet mopping cloths dissolve dirt and grime for good, trapping it in its core and locking it away. *Do not use Swiffer Sweeper wet cloths on unfinished, oiled, or waxed wooden boards, non-sealed tiles or carpeted floors.
