An automated self propelled refuse container travels from a parking or storage location to a refuse discharge location and return in response to a control unit cooperating with a tracking unit to control the direction of travel. Power is provided by an electric motor associated with each of two driving wheels rotating at the same rate and a third steering wheel provides stability and control over the direction of travel. The two driving wheels may rotate at a constant rate for straight line travel or charge direction, respectively, and a castering wheel provides stability and accommodates the direction of travel. Alternatively, a single wheel can provide both motive power and steering capability under control of a control unit responsive to the tracking unit and a pair of free wheeling wheels provide stability.
