A system to assist product stocking on a sales floor of a retail shopping facility comprises plural motorized transport units, each configured to perform multiple different types of tasks. A central computer coordinates the transport units in performing their tasks and instructs a transport unit to fetch a specified stocking cart by autonomously transporting it to a specified first stocking location on the sales floor. The type of coupler on a cart may be detected and a transport unit selected having a corresponding mating coupler. The transport unit may detect, and avoid collision with, a customer. The transport unit may detect a worker and follow the worker during restocking. The weight of the cart may be compared to the expected weight to confirm that the corresponding quantity of products is present. Sensor data can confirm that the cart has been unloaded and the transport unit instructed to repeat the task or to complete a different task. Waste may be detected in the unloaded cart and the cart moved to a waste disposal area
