According to Vileda advertising, "For all floors: You can use the Steam XXL steam cleaner on all hard floors, such as parquet, laminate or tiles. Thanks to the carpet glider, the hygienic cleaning of carpets is also successful."
For parquet, you should then set the steam control to minimum (Vileda: "By operating the steam control, you adjust the steam strength exactly to the cleaning need. Even delicate floors can be treated without risk this way.").
