Selon l'invention, pour améliorer la manipulation d'une buse de sol d'un appareil de nettoyage à vapeur, qui comporte un réservoir de liquide, un dispositif de génération de vapeur en communication fluidique avec le réservoir pour générer une vapeur de liquide et un conduit de liaison en communication fluidique avec le dispositif de génération de vapeur, laquelle buse de sol d'appareil de nettoyage à vapeur comporte un corps de buse qui est pourvu d'au moins un orifice de sortie de vapeur et d'un élément de raccordement qui est accouplé au corps de buse, et qui définit en particulier de manière articulée un conduit d'élément de raccordement pourvu d'une partie d'accouplement, laquelle partie d'accouplement est accouplée en permanence ou peut être accouplée temporairement au conduit de liaison, en particulier en forme de tuyau ou de tube, en communication fluidique avec le dispositif de génération de vapeur; la buse de sol d'appareil de nettoyage à vapeur comporte une articulation rotative, définissant un axe de rotation, pour faire tourner la partie d'accouplement et le corps de buse l'un par rapport à l'autre sur l'axe de rotation, une articulation à basculement, définissant un axe de basculement transversal à l'axe de rotation, pour faire pivoter la partie d'accouplement et le corps de buse l'un par rapport à l'autre sur l'axe de basculement et un moyen de freinage coopérant avec l'articulation à basculement pour appliquer une force de freinage ou un couple de freinage sur l'articulation à basculement, la partie d'accouplement et le corps de buse pouvant pivoter l'un par rapport à l'autre sur l'axe de basculement en s'opposant à l'action de ladite force. En outre, l'invention concerne un appareil de nettoyage à vapeur amélioré.
