The Swiffer SteamBoost is a steam mop that deeply penetrates dirt and helps remove messes mops can leave behind. Fill it with water, attach a Steam Pad and plug it in. No other cleaning solutions are needed. The special Steam Pads have a steam-activated, dirt-dissolving cleaning solution that pulls dirt from surfaces and locks it away. SteamBoost is light, easy to use and safe on tile, finished wood and laminate floors. **Do not use on waxed or unfinished wood floors.
