1/4″ Inlet, Brass nozzle.
The sharper, more effective cleaning nozzle.
The comparative image shows a normal fan jet nozzle on the left, and the Knife-Jet on the right, with a clearly thinner fan jet.
The area where the Knife-jet hits the ground is approx. 75% smaller compared to a conventional fan-jet. The same pressure is applied to only 25% of the area hit by the fan-jet so that the pressure taking effect on the ground is four times bigger, leading to an enormously increased cleaning performance!
