Best Overall
Shark Steam & Scrub Steam Mop, All-in-One Hard Floor Cleaner, Grey, S8001
Our verdict: Steam and a scrub function in one mop, chemical-free, for confirmed sealed stone.
The S8001 combines steam with a scrub function, so water vapor does the sanitizing and the pad does the loosening. That matters on stone because it removes the need for a cleaning solution, the usual source of etching on marble and limestone. The listing restricts it to confirmed sealed stone.
It ranks first because it is the lowest-risk method here: nothing acidic touches the floor. Against the wet-dry vacuums, steam applies heat that sealed stone tolerates only if the sealer is intact. It costs $100 to $200, level with the Dreame and roborock.
Buy it if you want chemical-free cleaning on sealed stone. The caveat: steam is wrong for unsealed or cracked surfaces, so check your sealer first.
