The Rag Company Ultra H2O Foam Cannon

Precision Control. Exceptional Foam. Built to Perform.

The The Rag Company Ultra H2O Foam Cannon was designed in-house at The Rag Company with the same philosophy that defines the entire Ultra H2O line: every detail matters.

Built completely from the ground up, the Ultra H2O Foam Cannon isn't simply a reworked version of an existing design or a collection of borrowed features. Every adjustment, material choice and touchpoint has been intentionally engineered to deliver a foam cannon that performs at a high level while also feeling exceptionally refined in your hands.

From the first adjustment, you'll notice the difference. The Ultra H2O Foam Cannon features positive tactile detents across its adjustment controls, giving you precise, repeatable control over your settings. Whether you're adjusting the soap-to-water ratio, rotating the fan pattern or fine-tuning the spray width, each click provides clear feedback so you can confidently dial in your preferred setup and return to it wash after wash.

Inside, the Ultra H2O Foam Cannon is built for long-term service. Full stainless steel internals provide excellent durability and corrosion resistance, while the fully rebuildable design means the cannon can be serviced and maintained for years of dependable use.

Performance is further optimised with a weighted pickup tube and two included orifice options — 1.1 and 1.25 — allowing the foam cannon to be better matched to a wide range of pressure washer setups.

The chemical-resistant HDPE bottle is designed with everyday usability in mind. Clearly marked ounce and millilitre measurements make dilution and product mixing straightforward, while the wide-mouth, quarter-turn lid makes filling, emptying and cleaning quick and convenient.

Finished with strategically positioned rubberized grip points and a clean, purposeful design, the Ultra H2O Foam Cannon pairs seamlessly with the Ultra H2O Spray Gun to create a complete pressure washing 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.

Key Features

Purpose-Built From the Ground Up

The Ultra H2O Foam Cannon wasn't created by modifying an existing design. The Rag Company developed it from the ground up, considering every adjustment, material and contact point to create a more refined foam cannon experience.

The result is a tool that combines high-level performance with the kind of thoughtful design that becomes noticeable every time you use it.

Positive Tactile Adjustment Detents

Precision control is at the heart of the Ultra H2O Foam Cannon.

Each adjustment is designed with positive tactile detents, giving you a distinct click as you make changes. This allows you to confidently fine-tune your settings and easily return to a preferred configuration from one wash to the next.

Adjust your settings with confidence rather than guessing.

Precise Soap-to-Water Adjustment

The adjustable soap-to-water control allows you to fine-tune your chemical delivery to suit your preferred wash process.

Whether you're looking for efficient chemical usage or adjusting the concentration to achieve your desired foam characteristics, the precise adjustment system gives you greater control over the process.

Adjustable Fan Pattern & Spray Width

The Ultra H2O Foam Cannon provides control over both the fan pattern and spray width, allowing you to tailor the application to the task at hand.

From broad vehicle coverage to more controlled application, these adjustments make it easier to achieve consistent coverage while working around different areas of the vehicle.

Full Stainless Steel Internals

Durability is built into the heart of the Ultra H2O Foam Cannon.

With full stainless steel internals, the cannon is designed to provide dependable performance while offering excellent corrosion resistance — an important consideration for a tool that regularly comes into contact with water and cleaning chemicals.

Fully Rebuildable Construction

The Ultra H2O Foam Cannon is designed for long-term service rather than short-term use.

Its fully rebuildable design allows components to be serviced or replaced as required, helping extend the usable life of the foam cannon and making it a practical choice for enthusiasts and professionals alike.

Optimised for Different Pressure Washer Setups

Included 1.1 and 1.25 orifices provide additional flexibility when setting up your foam cannon.

Combined with the weighted pickup tube, these components help optimise chemical delivery and foam cannon performance across a broad range of pressure washer configurations.

Chemical-Resistant HDPE Bottle

The durable HDPE bottle is designed to handle regular exposure to detailing chemicals while remaining practical for everyday use.

The integrated ounce and millilitre markings make it easy to measure your solution accurately, helping you achieve consistent dilution ratios from one wash to the next.

Wide-Mouth Quarter-Turn Lid

Filling and cleaning shouldn't be a chore.

The wide-mouth bottle opening makes it easy to add your chosen cleaning solution, while the quarter-turn lid allows for quick and convenient opening and closing between washes.

Premium Grip Points

Strategically positioned rubberized grip areas provide a more comfortable and secure feel when handling and adjusting the foam cannon.

Combined with the clean, purposeful design, the result is a tool that feels as good in your hands as it looks on your pressure washer.

Designed to Work as a System

The Ultra H2O Foam Cannon was designed to complement the Ultra H2O Spray Gun, creating a cohesive pressure washing system from the connection at the hose through to the application of foam.

The matching design language, premium materials and thoughtful ergonomics make the two tools a natural pairing for anyone looking to create a refined, capable pressure washing setup.
