A trailer or container washing system includes a wheeled-cart adapted for being driven into and out of a container, such as a meat-hauling trailer. Water is supplied to rotating nozzles and a spray bar mounted to the cart. A valve system, including a a unique valve control, is provided to supply different volumes of water to the nozzles and spray bar during a cleaning process which includes pre-wash, floor cleaning, wash and rinse cycles. The cart is preferably mounted on a moveable or stationary dock for being located at the opening to the trailer or container and novel dock configurations are disclosed herein. One such dock includes an adjustable tip-pan for receiving water and debris draining from the container. Other features of the present invention include a novel hose reel, a specially designed system for controlling the winding and unwinding of the water supply hose as the cart moves into and out of the container, and a valve for diverting water from the nozzles to the spray bar.
