Abstract
A vacuum trash collection vehicle includes a debris container and a source of vacuum on the vehicle. There is a hose connected at one end to the debris container and has the source of vacuum applied thereto. The hose is open at its other end to form a debris collection nozzle. There is a boom for supporting the hose during use as a debris collection device. A vacuum pickup head is carried by the vehicle and there are operator controls for raising and lowering the pickup head. The pickup head has an opening of a size and shape to be connected to the hose nozzle. There is a driver accessible control for moving the hose and boom to utilize the hose nozzle as a debris collection device. The hose may be connected to the pickup head opening and thereby provide vacuum to the pickup head so that it functions as a debris collection device.
