A plate system converts a wheelbarrow to a receptacle for a vacuum device. The plate system includes a vacuum plate body, an intake port, an exhaust port, and a vacuum pump mounted to the vacuum plate body. The vacuum plate body has an upper surface, a lower surface, and a resilient gasket on the lower surface of the vacuum plate body around a perimeter of the vacuum plate body to form a seal between the upper perimeter of the wheelbarrow body and the lower surface of the vacuum plate body when the vacuum plate system is on the wheelbarrow body. The resilient gasket covers an area of the lower surface of the vacuum plate body sufficient to fit over the upper perimeter of a plurality of wheelbarrows having open bodies in a range of sizes.
