The Ultra H2O Foam Cannon was designed in-house at The Rag Company with the same philosophy that shaped the entire Ultra H2O line: every detail matters.
Built completely from the ground up, this isn't a reworked version of an existing design or a collection of borrowed features. Every adjustment, every material choice, and every touchpoint was intentionally engineered to create a foam cannon that not only performs at the highest level, but feels incredible to use.
What you'll notice first is the control. Every adjustment features positive tactile detents, allowing you to precisely dial in your preferred settings and confidently return to them wash after wash. Whether you're adjusting your soap-to-water ratio, rotating the fan pattern, or fine-tuning the spray width, each click has a purpose.
Inside, full stainless steel internals and a fully rebuildable design are built for years of dependable service, while the weighted pickup tube and included 1.1 and 1.25 orifices help optimize performance across a wide range of pressure washer setups. The chemical-resistant HDPE bottle features easy-to-read ounce and milliliter markings, along with a wide-mouth quarter-turn lid that makes filling and cleaning quick and effortless.
Finished with tasteful rubberized grip points and a clean, purposeful design, the Ultra H2O Foam Cannon pairs seamlessly with the Ultra H2O Spray Gun to create a system that looks as refined as it performs.
Because making great foam is only part of the experience. Using great tools is what makes you look forward to the next wash.

The Ultra H2O Difference
The Ultra H2O Foam Cannon wasn't built to simply make thick foam—it was designed to give you complete control over the entire process.
Every adjustment point features positive tactile detents, allowing you to quickly return to your preferred settings every single wash. Whether you're adjusting your soap ratio, rotating the fan pattern, or dialing in the spray width, each click has a purpose.
Combined with stainless steel internals, a fully rebuildable design, dual included orifices, and a weighted pickup system, the result is a foam cannon that feels as refined as the vehicles it's designed to wash.
