A method and apparatus for pressure cleaning, wherein fluid from a source of pressurized fluid is injected into, passes through, and is ejected from the crankshaft of a motor toward a surface that is to be cleaned. The crankshaft defines a crankshaft passage therethrough and has a crankshaft inlet end into which the fluid is injected and a crankshaft outlet end out of which the fluid flows. A distribution assembly is attached to the crankshaft outlet end and the fluid flowing out of the crankshaft outlet end flows through the distribution assembly and is discharged therefrom. The crankshaft rotates and causes the distribution assembly to rotate. The rotation and orientation of the distribution assembly causes the velocity of the fluid discharged from the distribution assembly to be greater than the velocity that would be achieved solely due to the pressure differential between the source of pressurized fluid and the environment at the outlet of the distribution assembly.
