A turbo nozzle replaces the fan nozzle on your water blaster to increase cleaning pressure by about 60%. It does this by concentrating water down into a pencil jet stream, rather than the usual wider spread of a fan jet stream. To make up for the jet stream covering a smaller surface area, the turbo nozzle spins in a circular motion at many thousands of times a minute. That way, the same amount of surface area is cleaned, but at a higher pressure.
