While others may suggest using a steam mop on a low setting for cleaning vinyl plank floors—particularly some SPC products—it is not recommended. In fact, some manufacturer warranties specifically say you should not steam mop your vinyl plank flooring.  Steam can eventually penetrate between the planks and get beneath the surface, possibly weakening the glue and causing swelling or warping. Generally, use a vacuum or a flat mop that is moist, rather than soaked with water, but always follow the manufacturer’s instructions for cleaning.
