MJJC Foam Cannon Pro V2 vs. S V3 vs MTM Hydro: Which Is the Best Snow Foam Lance

Foam cannons are an absolutely essential piece of detailing kit. It allows you to have a safe pre-wash and at least for me it is so aesthetically pleasing, making your cleaning experience a lot more enjoyable. You can even use them to apply wax and sealants saving protecting your paint and speeding up the drying process. 

The MJJC Foam Cannons are the favourite in the detailing industry. MJJC really changed the game with the Pro V2 - wide neck, wide-based, strong bottle and an amazing consistent shaving cream like foam - how could it get better? Well MJJC launched S V3, introducing some refinements but it raises the question: Is it truly better?

I am going to delve into the details, comparing the MJJC V2 and V3, evaluating their strengths and weaknesses, and examining how they fare against the MTM Hydro PF22.3.

The Importance of Foam Cannons

The real benefit of using foam in this way is the reduction in the need for manual scrubbing. When foam clings to the car’s surface, it encapsulates the dirt particles and allows them to be rinsed away with water. This minimizes the chances of scratching or swirling the paint during the wash, a common issue with traditional methods where dirt particles can drag across the paint surface while being scrubbed.

Using foam significantly enhances the cleaning process and saves time compared to scrubbing every inch of the vehicle. Foam also provides a more uniform coverage, ensuring that even hard-to-reach areas, like the wheels and undercarriage, get a thorough cleaning​.

MJJC Foam Cannon Pro V2 vs. S V3

Build Quality and Design

The V2 is praised for its robust construction, using brass parts. Its thick, wide-base bottle ensures stability during use, while its wide-mouth design makes refilling easy. The durable plastics used in its construction make it resilient to frequent use and occasional drops. The clear, measurement-marked bottle allows users to accurately mix solutions​.

The V3 introduces subtle refinements, such as a modernized clear bottle for better visibility of solution levels and a new twist-lock mechanism for easier assembly. While its lightweight design enhances manoeuvrability, it sacrifices some stability when the bottle is full​.

Foam Thickness and Coverage

The hallmark of the V2 is its ability to produce exceptionally thick foam, resembling shaving cream. This is achieved through its unique dual-layer gauze filter, which creates a dense, even layer that clings to vertical surfaces. However, its high draw rate can lead to rapid consumption of product​.

The V3 builds on this foundation, offering slightly more consistent foam production with less solution consumption. The V3 has even thicker foam but is so thick that it just clings to the car. This can be adjusted by the concentration adjustment but that does impact the panel impact ratio.

Adjustability and User Experience

The V2 provides excellent control over spray patterns and foam thickness but has been critiqued for the stiffness of its adjustment knobs. These require firm handling, especially for users with smaller hands​.

The V3 improves user experience with smoother adjustment mechanisms and an upgraded suction tube design. Its weighted tube ensures consistent solution pickup, even when the cannon is tilted during use​. Its key standard out feature is the quick connect, 1-turn nozzle head. I love this feature.

How the MJJC Pro V2 Stacks Up Against the MTM Hydro PF22.3

Foam Production

The MTM Hydro PF22.3, often considered the gold standard, produces foam with remarkable consistency. However, the V2 excels in creating denser foam that clings to surfaces longer, making it ideal for heavy-duty cleaning​.

Build Quality

The MTM Hydro boasts premium build materials, such as reinforced nozzles and heavy-duty plastics, ensuring longevity. While the V2 is highly durable, its materials may not withstand the same level of wear and tear​.

Value for Money

The MJJC Pro V2 offers 90% of the MTM Hydro’s performance at a significantly lower price point. For most enthusiasts, the V2 strikes the perfect balance between quality and affordability​. Really unless you are doing this as a professional, MJJC V2 or V3 is more than enough.

MJJC Foam Cannon Instructions: Maximizing Performance

Proper Dilution Ratios

Dilution ratios play a critical role in achieving optimal foam density. Start with a 1:10 ratio of snow foam to water, adjusting based on your specific cleaning needs. Using warm water can further enhance foam production​.

To calculate the panel impact ratio:

1. Fill your foam cannon with water to the 1-litre mark
2. Measure the amount dispensed
3. Multiply the dispensed volume by the desired percentage (e.g., 0.02 for a 2% ratio)
4. Add that amount of snow foam to the cannon and top up with water to reach the 1-litre mark.

Choosing the Right Pressure Washer

Foam cannons perform best with high-flow pressure washers. Look for models with a flow rate of 1.6–2.0 GPM for thick, consistent foam. For lower-powered units, consider using a smaller orifice size, such as the 1.1mm nozzle included with MJJC cannons​.

Maintenance Tips

• Flush your foam cannon with clean water after each use to prevent soap residue from clogging the nozzle.
• Regularly inspect and clean the filters to maintain peak performance.
• Store your foam cannon in a cool, dry place to avoid plastic warping​.

Recommended Snow Foam: Bilt Hamber Touchless

Bilt Hamber Touchless, when used with MJJC Foam Cannons, delivers a powerful and efficient cleaning experience. It produces dense foam that clings effectively, loosening dirt and grime with minimal effort.

When applied with an MJJC Foam Cannon, the rich foam covers the car evenly, thanks to the cannon’s precise spray adjustments and thick foam production capabilities. This combination maximises the dwell time of the foam, lifting contaminants for a streak-free rinse.

To optimise results, dilute Touchless at a 1:10 ratio for heavy cleaning or 1:20 for maintenance washes, (you should use 1-4% PIR for accurate dilution). The pairing of these two products ensures thorough pre-wash minimising risk to your car's finish. Whether you're a weekend warrior or a seasoned detailer, this duo guarantees spotless results every time.
