ABSTRACT:
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 microswitch, which activates a control mechanism for the carrier when a wheel assembly is in a predetermined position along its path of vertical movement. Rollers 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 wheel support, and which may also support a power source and a transmission.
