Nope! As long as you use wet or dry moping options according to your floor type. You can use either wet or dry moping options on all types of finished floors because it’s are entirely safe. But I like to suggest using only dry Swiffer mops on unfinished hard floors. These floors are quite sensitive and get damaged when exposed to a high level of wetness. NOTE: Avoid using wet Swiffer mops on waxed or oiled floorings.
