Griot's The BOSS™ Foam Cannon

A touchless wash is the safest and most efficient way to wash your car, and to achieve it, you need THE BOSS™ Foam Cannon!

Featuring the auto-mix system, this cannon delivers the ideal ratio of foaming solution to water. This saves you time on pre-mixing and ensures consistently thick, frothy foam with every burst.

Simply insert one of the three included metering tips into the metering ball to activate auto-mix. See the manual for the recommended tip to use with your pressure washer, as well as what jet (1.25 or 1.1).

Tilted or even upside down, the stainless-steel metering ball and flexible silicone tube keep a constant flow of foaming solution. That flow enters the manifold and goes through the barrel, both of which are also made of stainless steel for long-term durability and chemical resistance.

Inside the barrel, the foam spools up due to the machined rifling, frothing it before finally blasting out of the nozzle. That nozzle can also be adjusted to modify the spray pattern from a 0° stream for long range to a 40° fan for quick coverage.

To set up, attach the included 33.8 oz reservoir or one of our 22 or 35 oz bottles. Next, use the Stainless-Steel Pressure Washer Quick Coupler Plug to connect to your pressure washer. Finally, turn the foam adjuster knob all the way up and have fun.

PRO TIP: Pair with THE BOSS Pressure Washer Gun for a seamless cleaning experience that tackles even the toughest grime.
