The X-Jet M5 nozzle is a great way to soft wash with your pressure washer. The M5 nozzle can be used with almost any gpm (gallons per minute) machine from 2.3 gpm up to 8gpm.
The X-Jet has a unique design that allows it to inject and proportion liquids at high pressure without going through your pump, hose or gun. With this feature you can reach heights over 40 feet when using the washer with an appropriate set up for spraying from one point on top of another! The process is also much easier than traditional methods because there's no need for lances which have been known in some cases not only be costly but dangerous too so anything worth doing should always involve fewer steps right?
The Xjet is a great pressure washing tool that allows soft washing with a power washer. The Xjet method is a cheap way to get started soft washing, it is also a great alternative to 12v pumps and other soft wash systems.
The Xjet is attached to the end of your lance which allows you to apply your chemical without it having to go through your hose or gun. A down stream injector is installed near the outlet of the pump which runs through the hose and gun. The benefit of a down stream injector is that you don't have to carry your chemical bucket around the property with you.
