Abstract

La présente invention concerne un dispositif de nettoyage (100) comprenant : une base (10) ; deux ensembles d'entraînement (40) agencés sur la base (10) à un intervalle et utilisés pour entraîner la base (10) en déplacement ; un ensemble de nettoyage (30) raccordé à la base (10) et situé sur un côté des deux ensembles d'entraînement (40) de façon à nettoyer une surface de nettoyage ; et une roue omnidirectionnelle (103) raccordée à la base (10) et située sur l'extrémité de la base (10) à distance de l'ensemble de nettoyage (30). La roue omnidirectionnelle et l'ensemble de nettoyage (30) sont respectivement disposés sur deux côtés des deux ensembles d'entraînement (40). La roue omnidirectionnelle (103) sert à aider à supporter la base (10) lorsque le dispositif de nettoyage (100) rencontre un obstacle. Le centre de gravité du dispositif de nettoyage (100) est situé dans une zone triangulaire formée par les points centraux des roues des deux ensembles d'entraînement (40) et par le point central de l'axe de l'ensemble de nettoyage (30). Le dispositif de nettoyage (100) peut utiliser l'ensemble de nettoyage (30) pour remplacer une roue d'entraînement avant afin qu'il fasse office de point de support du dispositif de nettoyage (100). La structure de support du dispositif de nettoyage (100) est donc très simple. De plus, le nombre de pièces du dispositif de nettoyage (100) en contact avec le sol est réduit, ce qui prévient efficacement toute recontamination du sol nettoyé.
