Abstract

L'invention concerne un robot de nettoyage automobile, appartenant au domaine technique des robots intelligents. Le robot de nettoyage automobile comprend un corps (1). Un dispositif de distribution d'eau et une unité de nettoyage sont prévus sur la partie inférieure du corps (1). Le dispositif de distribution d'eau sert à distribuer la solution de nettoyage sur une surface à nettoyer, et il peut flotter le long de la direction verticale par rapport au corps (1). Lorsqu'il est en fonctionnement, le dispositif de distribution d'eau entre naturellement en contact avec la surface à nettoyer du fait de son propre poids. Le robot de nettoyage automobile peut passer sur les particules accumulées de poussière, et peut éviter un blocage ou un enchevêtrement causé par la poussière ou les cheveux. Il présente une plus grande aptitude à la circulation et évite le problème d'engorgement provoqué par l'accumulation de poussière.
