Different vacuums work better on some surfaces than others, and the same is true for vacuum-mop combos. All vacuum-mops can be used on hard floors, including sealed wood, vinyl, and tile. The Roborock S7+ and Black+Decker can be used on both hard floors and carpets, and the Bissell Crosswave can be used on hard floors and area rugs. We always recommend taking stock of what surfaces you’ll need to clean before buying a vacuum, so you can pick a model that will excel wherever you use it.
