Patent number: 12247372Abstract: A boom turret for a debris body. The boom turret includes an inlet defining an inlet axis and configured to couple to a hose. An outlet defining an outlet axis and configured to rotatably couple to the debris body. The inlet axis is substantially orthogonal to the outlet axis and a debris flow path is defined within the boom turret between the inlet and the outlet.
