Not with ours! Many foam cannons require a pressure washer connection, but Captains Preferred Products' foam cannon hooks up to any garden hose for ease of use. No pressure washer required!

What's the best foam cannon soap?

We recommend using Captain's Fury Wash + Wax Boat Soap with our foam cannon. You can also use any high-foam car wash soap if washing your car, truck, or RV.

How much soap should I use in my foam cannon?

We recommend filling the foam cannon body up about 1/4 of the way with soap. Try that first. You can always adjust the amount of soap and the foam dial to achieve maximum foaminess.

How do I use a foam cannon for a car wash?

Fill your foam cannon with soap, and hook it up to a hose. Spray the foam all over the surface of your car. Let the soap sit briefly, and then use a wash mitt or sponge to loosen up any dirt and grime. Unhook the foam cannon body, and rinse the car off with fresh water. To avoid water spots, use a shammy cloth to dry it off.
