1. A boom turret for a debris body, the boom turret comprising:
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, wherein 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;
a plate disposed between the inlet and the outlet and having a surface at least partially defining the debris flow path through the boom turret;
a nozzle coupled to the plate and extending into the debris flow path, the nozzle including an impact cover parallel to the plate and spaced apart therefrom, the nozzle defining a nozzle axis and at least one opening at least partially defined by the impact cover, the at least one opening oriented in a direction that is orthogonal to the nozzle axis; and
a pressure vessel configured to hold a charge of pressurized fluid, wherein the pressure vessel is coupled in flow communication with the nozzle and selectively releases the charge of pressurized fluid through the nozzle to dislodge accumulated debris within the debris flow path.
