Pour le nettoyage d'un sol lisse, et en particulier pour enlever des taches présentes sur le sol lisse, il est connu, notamment du document
Un tel dispositif de nettoyage humide comporte :
- un support de serpillère sur lequel est destinée à être montée une serpillère,
- un réservoir de liquide de nettoyage qui est situé au-dessus du support de serpillère et qui est configuré pour alimenter en liquide de nettoyage une serpillère montée sur le support de serpillère, le réservoir de liquide de nettoyage comportant une sortie de liquide prévue dans une partie inférieure du réservoir de liquide de nettoyage,
- un organe d'obturation qui s'étend selon un axe d'extension et qui est monté mobile par rapport au réservoir de liquide de nettoyage entre une position d'obturation dans laquelle l'organe d'obturation obture la sortie de liquide et une position de libération dans laquelle l'organe d'obturation libère la sortie de liquide,
- un joint d'étanchéité annulaire inférieur qui est monté sur une partie inférieure de l'organe d'obturation et qui est configuré pour empêcher un écoulement de liquide de nettoyage à travers la sortie de liquide lorsque l'organe d'obturation occupe la position d'obturation, et
- un joint d'étanchéité annulaire supérieur qui est monté sur une partie supérieure de l'organe d'obturation et qui est donc décalé axialement, selon l'axe d'extension de l'organe d'obturation, par rapport au joint d'étanchéité annulaire inférieur.
