stone.

According to Shark, you cannot use them on unsealed wood, unglazed ceramic floors, or any surfaces that have been treated with wax, since the sheen may be removed by the heat and steam action.

All of then use only water, the manuals state that users cannot add cleaning solutions, scented perfumes, oils or any other chemicals to the water used in these mops, because this may damage the unit or make it unsafe for use.
