There is a hose connected at one end to the debris container and the source of vacuum is applied thereto. The opposite end of the hose is open to form a collection nozzle. A boom supports the hose during use as a debris collection device. There is a driver accessible control for moving the hose and nozzle which includes an elongated tubular assembly, pivotally mounted at its upper end to the boom and movably mounted at its lower end to the collection nozzle. There is an operator's handle, having multiple hand-gripping areas, mounted on the tubular assembly and movable relative thereto during use of the debris collection hose.
