What is the MJJC Foam Cannon Pro V3.0?
The MJJC Foam Cannon Pro V3.0 is the latest evolution of MJJC’s highly popular snow foam lance range. Designed for use with a pressure washer, it produces thick, clinging foam to safely loosen dirt and grime before contact washing. The V3.0 model improves on earlier versions with upgraded internals, a wider neck design for stability, a larger mouth bottle, and refined adjustment controls for both spray pattern and foam thickness.
What others are saying
- Detailers and enthusiasts praise the thick, shaving cream-like foam it produces with very little product.
- Many highlight the improved bottle design, which prevents tipping over when placed on the ground.
- It’s often rated as one of the most consistent and durable foam cannons on the market, with excellent build quality for the price.
My experience
I’ve used several foam lances over the years, but the MJJC Foam Cannon Pro V3.0 genuinely stands out. Straight away, the build quality impressed me. The brass fittings felt solid, and the bottle had a wide base which made it far less likely to topple over — something that has always been a frustration with cheaper foam cannons.
When it came to actual performance, the foam quality was superb. I filled the bottle with around 900ml of water and 100ml of snow foam solution, gave it a quick shake, and connected it to my pressure washer. Within seconds, the car was covered in a dense, clingy blanket of foam that stayed in place long enough to lift dirt before rinsing. Unlike some cheaper alternatives that produce watery foam, this genuinely looked and felt like thick shaving cream.
The adjustment controls were responsive and easy to dial in. I could quickly switch between a wide fan for faster coverage and a narrow stream for targeting wheel arches or lower panels. The foam mixture dial also allowed me to reduce soap usage when just maintaining a lightly soiled car — a real bonus for efficiency and cost-effectiveness.
Over several washes, I also noticed how little product it actually used compared to other foam cannons I’ve owned. The improved internals clearly make it more efficient. The bottle’s wide neck was another win — no more spilling product when filling up, which is something I’ve struggled with using older designs.
One thing that particularly stood out in my testing was just how consistent the foam quality remained, even after multiple uses. With cheaper foam cannons, I’ve often noticed a drop-off in performance after a few washes, but the MJJC Pro V3.0 delivered the same thick coverage every time. It felt like a tool designed not just for enthusiasts, but also capable of withstanding regular use by professionals.
Another detail I really appreciated was how stable it felt during use. Once attached, the cannon had a nice balance, and the bottle didn’t feel flimsy or prone to twisting. This gave me more confidence when working around the car, especially on longer detailing sessions where comfort and control matter.
Before purchasing the MJJC Foam Cannon Pro V3.0, please ensure the following:
1. Check Your Pressure Washer’s Operating Pressure
Your pressure washer must operate at a minimum of 50 BAR / 725 PSI.
Each Foam Cannon Pro V3.0 comes pre-installed with a 1.25mm orifice, which is ideal for machines rated between 110 Bar (1595 PSI) and 150 Bar (2175 PSI).
Spare parts included in the package:
- 1.1mm orifice – suitable for machines operating 90 Bar / 1305 PSI ~ 110 Bar / 1595 PSI.
- 1.35mm orifice – recommended for machines rated 150 Bar / 2175 PSI ~ 280 Bar / 4061 PSI.
If your pressure washer falls outside these ranges, you’ll need to purchase the appropriate orifice size for optimal performance.
Orifice size guide:
- 0.9mm orifice: 50 Bar / 725 PSI ~ 90 Bar / 1305 PSI
- 1.1mm orifice: 90 Bar / 1305 PSI ~ 110 Bar / 1595 PSI
- 1.25mm orifice: 110 Bar / 1595 PSI ~ 150 Bar / 2175 PSI
- 1.35mm orifice: 150 Bar / 2175 PSI ~ 280 Bar / 4061 PSI
- 1.65mm orifice: 280 Bar / 4061 PSI ~ 340 Bar / 4931 PSI
2. Confirm Your Pressure Washer Type
This foam cannon is designed for use with Cold Water pressure washers only. It is not compatible with hot water machines.
How to use
- Fill the bottle with approximately 900ml of water and 100ml of snow foam solution.
- Screw the bottle onto the foam cannon securely and connect to your pressure washer.
- Adjust the top dial to control foam concentration (more soap vs. more water).
- Use the front nozzle to change the spray pattern from wide fan to narrow jet.
- Apply foam from the bottom of the car upwards to ensure even coverage and reduce streaking.
- Allow foam to dwell, then rinse thoroughly before moving on to a contact wash.
Final thoughts
The MJJC Foam Cannon Pro V3.0, priced at £82.00, is without doubt one of the best foam lances I’ve ever used. It produces dense, clinging foam with minimal product, feels durable, and the bottle design solves the annoying “tipping” issue. At its price point, it offers exceptional performance that rivals much more expensive alternatives.
Pros:
- Thick, clingy foam that lifts dirt effectively
- Solid brass fittings and durable design
- Wide, stable bottle with large opening
- Efficient soap usage compared to other foam cannons
- Easy-to-adjust spray pattern and mixture
Cons:
- Requires a pressure washer — not suitable for hose-only users
- Initial cost is higher than budget foam lances, though worth it for performance
