A carrier, such as an autonomous cleaning apparatus, has a self-adjusting wheel assembly that can move vertically, thereby enabling the carrier to readily pass over a surface. The wheel assembly may include actuating means, which activates a control mechanism for the carrier when a wheel assembly is in a predetermined position along its path of vertical movement. Rotatable support means can be located at the bottom of the carrier to function in cooperation with the wheel assemblies so as to facilitate the ability of the carrier to pass over obstacles. This ability may be enhanced by constructing the bottom of the front portion of the carrier so that it is slanted or inclined upwardly in a direction outward from the bottom of the carrier. A driving wheel may be rotatably attached to a support means, and which may also support a power source and a transmission means.
L'invention concerne un appareil de nettoyage autonome tel qu'un aspirateur robot. L'appareil a un boîtier enfermant un contenant de poussières, une source de vide à commande électrique et une buse par laquelle les particules de poussière s'écoulent dans le contenant de poussière. Le boîtier est directement ou indirectement supporté par un système de roues ayant au moins deux roues (12) entraînées individuellement. Chaque roue est soutenue par un support (16) amovible qui est conçu pour être pressé sur une surface sol à l'aide d'un dispositif de type ressort. Chaque roue d'entraînement (12) est entraînée par un moteur électrique (17) et une transmission (18) est montée sur le support de roue d'entraînement. Chaque roue d'entraînement peut se déplacer verticalement, ce qui permet à l'appareil de surmonter les obstacles, les surfaces non planes et les bosses.
