A motorised, wheeled, transport unit 202 for use with a mobile item container 302 such as a shopping cart or trolley monitors location information to position and align the transport unit relative to the trolleys frame. A lift system lifts on the frame of the trolley so that a portion 304 of the trolley is lifted off the floor whilst at least two wheels 306 remain on the floor. The lift system comprises several spaced hydraulic lifts which may adjust the weight distribution between wheels and thus improve traction in response to a detected reduction in traction in the transport units wheels. A pair of arms 1002 may be provided that are rotatably cooperated with the transport units body, and an actuatable clamp on each arm may be positioned relative to the item containers frame by rotating the arms. The control circuit may communicate wirelessly with a central computer system.
