MJJC Foam Cannon Pro V2.0 Pressure Washer Foam Cannon — 40 oz Bottle, 1/4" Quick Connector, Thicker Snow Foam

MJJC Foam Cannon Pro V2.0 is a heavy-duty pressure-washer foam cannon that produces dense, creamy snow foam using less shampoo and includes a 1/4" quick-connect adapter and a 40 oz (≈1200 ml) bottle.

Designed for enthusiasts and professional detailers, the Pro V2.0 upgrades the original Foam Cannon with a larger reservoir, reinforced construction, and a new nozzle system to deliver richer foam while being easier to hook up to modern pressure washers. It works across a wide operating pressure range and comes with multiple orifice options so you can tune foam thickness for different machines.

How much foam and shampoo savings can I expect?

The Pro V2.0 is engineered to create much denser foam while using less shampoo. Its larger bottle and internal design increase foam volume and density, producing up to 30% thicker foam than the classic model when mixed at recommended ratios.

• 40 oz (about 1200+ ml) tank for longer runs between refills.
• Effective mixing at roughly 1:9 shampoo-to-water ratios (100 ml shampoo per 900 ml water).
• Produces rich, clingable foam that covers larger surfaces quickly.

Will it work with my pressure washer and what nozzle should I use?

The cannon supports a broad operating range from roughly 1300 psi to 3600 psi, but nozzle size matters: the kit ships with a 1.25 mm orifice preinstalled for medium-pressure machines. Swap to the included 1.1 mm nozzle for lower-pressure cleaners or move to larger orifices for higher-pressure units to maintain optimal foam performance.

• Pre-connected 1.25 mm nozzle suitable for ~1600–2200 psi systems.
• Included 1.1 mm nozzle recommended for ~1300–1600 psi washers.
• For >2200 psi, use 1.35 mm or larger orifice nozzles (available separately).

How easy is it to connect and maintain?

The Pro V2.0 adopts a simplified attachment system that eliminates the need for PTFE tape or glue and includes a 1/4" quick connector adapter for fast hookup. The unit’s robust build reduces the chance of leaks or breakage, and the wide bottle opening makes filling and rinsing quick and convenient.

• 1/4" quick-connect adapter included for faster setup.
• New connection design reduces dependence on sealants or tape.
• Durable construction for repeated use and easier cleaning.

What performance gains will detailers notice on cars and surfaces?

Because the foam is creamier and clings better, dirt lift and dwell time improve compared with thinner foam. That makes it simpler to loosen road grime and particulate before manual contact washes, reducing the risk of swirl marks when rinsed or hand-washed afterward.

• Thicker foam clings to vertical surfaces for longer, improving cleaning time.
• Higher foam density helps distribute detergent evenly across panels.
• Works effectively even at lower pressure settings when the correct nozzle is used.

Who is this for: The MJJC Foam Cannon Pro V2.0 is aimed at car enthusiasts, mobile detailers, and anyone with a pressure washer who wants stronger snow foam coverage, lower chemical usage, and a more reliable, easy-to-connect foam cannon. Choose this model if you need a larger-capacity bottle, tougher build quality, and the flexibility to optimize foam across low- to high-pressure washers.
