Le dispositif peut également permettre d'obtenir de meilleurs résultats en matière de nettoyage et de désinfection. La vapeur produite par l'appareil de génération de vapeur pénètre dans le tambour de séchage des vêtements par l'intermédiaire du conduit d'air de séchage, et une diffusion parfaitement homogène peut être obtenue sans qu'il soit nécessaire d'ajouter la moindre force d'entraînement supplémentaire.
