Rockcar Stealth Snow Foam Cannon – Blackout Edition

Exceptional foam. Precision engineering. Built to last.

We've tested nearly all the leading snow foam cannons on the market, and we haven't found one that produces better foam than the Rockcar Stealth.

What really impressed us, however, was the engineering. We took one apart to see how it was made and were particularly impressed with the quality of the internal components — especially those you don't normally see.

Many foam cannons are designed primarily around appearance and price. The Rockcar Stealth is engineered for performance, durability and serviceability. It just happens to look pretty good too.

Features & Benefits

• Exceptional Foam Production: A precision stainless steel mesh foamer and interchangeable orifice produce thick, dense foam for excellent coverage and dwell time.

• Fully Serviceable: Replacement parts are available, including bottles, mesh filters, orifices, hoses and fittings. Maintain and repair your foam cannon rather than replacing it.

• Durable Construction: Solid brass housing with a thick black epoxy coating for additional chemical and corrosion resistance, plus quality stainless steel fittings.

• Precision Controls: Independently adjust the soap concentration, foam spread and spray angle for greater control over foam application.

• Smart Bottle Design: Large, clear bottle with accurate metric markings, a wide opening for easy filling and a flexible intake hose with an integrated filter.

• Customisable Performance: Interchangeable orifices and optional hose upgrades allow you to tailor the foam cannon to your water blaster and how you use it.

Engineered for Exceptional Foam

The stainless steel mesh foamer is one of the most important components in a quality foam cannon.

As the high-pressure mixture of water and snow foam passes through the fine stainless steel mesh, it is aerated to produce thick, rich foam.

The Rockcar Stealth uses a high-quality stainless steel mesh engineered to maximise foam production. Combined with the correctly sized orifice and a quality snow foam soap, it delivers exceptionally dense, stable foam.

We've tested it against many of the best foam cannons available and haven't found one that foams better.

The mesh is also replaceable, so if it eventually becomes clogged or worn, you can replace the component rather than the entire foam cannon.

Interchangeable Orifices – Optimise Performance for Your Water Blaster

The internal orifice controls the flow of water through the foam cannon and plays an important role in foam production and pressure washer compatibility.

Using the correct orifice helps balance water flow and back pressure. An orifice that's too restrictive for your machine can cause excessive back pressure and, on some pressure washers, lead to the pump repeatedly switching on and off, commonly called surging.

The Rockcar Stealth comes pre-assembled with a 1.1mm stainless steel orifice, suitable for many domestic water blasters.

Alternative orifice sizes are available separately:

The correct orifice depends on your water blaster's pressure and flow rate, not pressure alone.

One of the great advantages of the Stealth is that you can change the orifice if you upgrade your water blaster or need to adjust performance. There's no need to replace the entire foam cannon.

Solid Brass Construction – Built for Durability

The main housing is manufactured from solid brass, a material well suited to pressure washer components because of its durability and corrosion resistance.

Rockcar has gone a step further, adding a thick black epoxy coating for additional protection against chemicals and corrosion.

The standard ¼-inch quick-connect fitting is made from high-quality stainless steel.

It's robust, functional and finished in the understated Blackout Edition design.

Precision Foam Controls

The Rockcar Stealth gives you three independent adjustments:

• Soap Concentration: Adjust the ratio of cleaning solution drawn from the bottle into the water flow using the control on top.

• Foam Spread: Adjust the spray pattern from a narrow stream to a wide fan.

• Spray Angle: Rotate the foam nozzle to change the orientation of the spray while keeping the bottle upright.

The adjustable spray angle is particularly useful when cleaning lower panels, awkward areas or when you want a horizontal or vertical spray pattern without tilting the bottle.

A Better Bottle Design

Even the bottle has been carefully considered.

It's large and completely clear, making it easy to see how much cleaning solution remains. Accurate metric markings allow you to measure your snow foam and water directly in millilitres.

The wide-mouth opening makes filling easier and is designed for durability, helping distribute the weight of a full bottle around the neck.

Inside, the long, flexible intake hose reaches across the bottom of the bottle without easily kinking or sealing itself against the base.

A filter at the end of the hose helps prevent debris from entering the internal foamer mesh, supporting consistent performance.

Optional Gravity Ball Intake Hose Upgrade

For those who like to customise their equipment, Rockcar also offers an optional neon green flexible intake hose with a stainless steel filter and weighted gravity ball.

The weighted filter moves towards the lowest point in the bottle as you tilt the foam cannon, helping it continue drawing cleaning solution when the bottle is held at an angle.

This is particularly useful when cleaning lower vehicle panels or when the bottle is nearly empty.

The hose can also be trimmed to suit your preferred setup.

Please note: The gravity ball intake hose is an optional upgrade and is not included with the standard Rockcar Stealth Foam Cannon.

Fully Serviceable – Replacement Parts Available

One of the biggest differences between the Rockcar Stealth and many other foam cannons is that it's designed to be maintained and repaired.

Replacement parts and upgrades are available, including:

• Replacement bottles

• Replacement tops and components

• Stainless steel foamer mesh filters

• Interchangeable stainless steel orifices

• Intake hoses and filters

• Optional gravity ball hose upgrades

• Adapters for different water blaster fittings

If a component wears out, becomes clogged or gets damaged, you can replace the part rather than throwing away the entire foam cannon.

That's better for the longevity of your equipment and can save money over time.

Water Blaster Compatibility & Adapters

The Rockcar Stealth comes with a standard ¼-inch stainless steel quick-connect fitting, commonly used on professional pressure washer triggers and many larger water blasters.

If your water blaster uses a proprietary connection, you'll need a compatible adapter, available separately.

We stock adapters for a wide range of brands commonly sold in New Zealand, including Kärcher, Bosch, AVA, Nilfisk, Gerni, Ryobi, Ozito, Makita, DeWalt and Stihl.

Some manufacturers use different fittings across their models, so it's important to check your connection before ordering.

Not sure which adapter you need? Contact us with your water blaster's brand, model and a photograph of the connection on your trigger. We'll help identify the correct fitting.

Want the Complete Setup?

We also offer the Rockcar Stealth Foam Cannon Kit, which includes the Stealth Blackout Edition, 500ml of Autostolz Snow Foam and your choice of water blaster adapter.

It's an easy way to get everything you need in one package, and offers excellent value compared with purchasing the components individually.

Why We Recommend the Rockcar Stealth

We love the understated Blackout Edition design, but it's the performance and engineering that make this foam cannon stand out.

From the precision stainless steel mesh and interchangeable orifices to the solid brass housing, thoughtful bottle design and availability of replacement parts, the attention to detail is impressive.

It's easy to use, produces outstanding foam and is built to be maintained rather than discarded.

This isn't your average foam cannon. It's engineered to perform and built to last.

Important: The Rockcar Stealth is designed for use with a pressure washer (water blaster). It does not connect directly to a standard garden hose. Snow foam cleaning solution and brand-specific adapters are sold separately.
