A Canadian trademark record identifies the corporate entity as Mjjc Manufacturing Co., Ltd., located in Huadu District, Guangzhou, Guangdong, China.

2011: Founding

MJJC traces its origins to April 2011. The founders were interested in the potential of foam lances as a dedicated tool for vehicle washing, drawing inspiration from existing Italian and British brands. They decided to develop their own foam lance, adopting the initials of the four founders—Michael, Jeremy, Justin, and Calvin—as the brand name.[1]

2012: First MJJC foam lance

After approximately a year of development, MJJC produced its first foam lance in July 2012. The company subsequently began exporting its foam lances to the United States, Europe, and other markets, establishing the foundation for its international business.[1]

2016: Entry-level foam lance

In 2016, MJJC expanded beyond its original product positioning with a lighter and less expensive foam-lance design. The objective was to provide a more accessible product while retaining the performance characteristics of its established foam-lance products.[1]

2019: Foam Cannon Pro V1

MJJC introduced its first Foam Cannon Pro in 2019 after approximately a year of development. This marked a shift toward a more sophisticated, performance-oriented foam-cannon product rather than competing solely as a generic foam-lance manufacturer.[1]

2021: Foam Cannon Pro V2

Following customer feedback on the first Pro model, MJJC released the Foam Cannon Pro V2.0 in 2021. Advertised improvements included better foam performance, reduced noise, improved fittings, a larger bottle, and greater compatibility with lower-pressure machines. The company states that the V2 could produce up to 30% thicker foam than its predecessor under appropriate conditions.[1]

2022: S V3.0 and MJJC shampoo

In September 2022, MJJC introduced the Foam Cannon S V3.0 together with its own foam shampoo. The S-series was intended to make foam-cannon operation easier while improving foam thickness, efficiency, and usability.[1]

2024: Pro V3.0

MJJC released the Foam Cannon Pro V3.0 on December 10, 2024. The V3.0 represents the latest major generation of the company’s Pro-series foam cannon. It features a stainless-steel component, a redesigned bottle and groove, an anti-leak cap, and claimed “shaving cream” foam performance when used with suitable shampoo and pressure washers.[1]

MJJC’s product portfolio centres on pressure-washer car washing rather than general automotive parts.

Foam cannons

Foam cannons are MJJC’s core category. These devices attach to a pressure washer and mix water, air, and car shampoo to produce a layer of cleaning foam applied before physical washing. Major generations include:

• Foam Cannon Pro V1.0
• Foam Cannon Pro V2.0
• Foam Cannon Pro V3.0
• Foam Cannon S V2.0
• Foam Cannon S V3.0
• Various pressure-washer-specific versions and fittings

The company emphasises thick, creamy foam, reduced shampoo consumption, and compatibility with relatively low-pressure machines.[1]

Foam shampoo

MJJC sells its own MJJC Foam Shampoo, designed specifically for use with its foam cannons and foam guns. This allows the brand to participate in both the equipment and chemical sides of the foam-washing system.[1]

Trigger guns and short guns

The brand offers products such as the Trigger Gun V2.0, short-gun-related equipment, and various adapters. These are intended to make pressure-washer-based detailing more ergonomic and easier to configure.[1]

Fittings and accessories

Because pressure washers use many different connection standards, MJJC supplies adapters and fittings for brands such as Kärcher, AVA, Nilfisk, Bosch, Makita, Stihl, and others. This compatibility ecosystem is essential as foam cannons are not universally plug-and-play across all pressure washers.

The central operating principle behind MJJC products is the sequence: pressure washer → foam cannon → air + water + shampoo → dense cleaning foam → vehicle.

The distinction between inexpensive generic foam guns and higher-end foam cannons lies in how effectively they control water flow, air intake, chemical concentration, orifice size, and foam mixture. MJJC places considerable emphasis on this engineering aspect. For example, product documentation specifies different orifice sizes for different pressure ranges. The S V3.0 documentation lists 0.9 mm, 1.1 mm, 1.25 mm, 1.35 mm, and 1.65 mm orifices for specific pressure ranges.[1]

This specificity is necessary because a foam cannon is not simply a device where more pressure equals more foam. The relationship between pressure washer flow rate, pressure, orifice size, detergent concentration, and foam-cannon design determines the final foam characteristics.

MJJC’s branding revolves heavily around thick foam. The concept behind snow-foam pre-washing is that detergent foam covers the vehicle and helps loosen or encapsulate dirt before the wash mitt physically contacts the paint. This can potentially reduce abrasive contamination during contact washing.

While MJJC describes its goal as producing thicker and creamier foam,[1] it is important to distinguish marketing claims from independently measured performance. Thick foam does not automatically equate to better cleaning; actual performance depends on detergent formulation, dilution, dwell time, water quality, pressure washer specifications, and the type of contamination present.

This progression indicates that MJJC has remained focused on a relatively narrow product category rather than rapidly expanding into unrelated automotive products.[1]

MJJC maintains two principal foam-cannon families.

Foam Cannon Pro

The Pro line is positioned as the higher-end platform. The current Pro V3.0 features a redesigned bottle with up to 1,200 ml internal volume, stainless-steel construction components, an anti-leak bottle cap, the MJJC connection/fitting system, and positioning for thick, shaving-cream-style foam. It supports various pressure-washer configurations.[1]

Foam Cannon S

The S line serves as an alternative platform. The S V3.0 emphasises easier handling, an improved bottle and cap, an updated straw tube, improved foam technology, and reduced soap consumption.[1]

In summary, the Pro series is the flagship, performance-oriented line, while the S series focuses on usability and value. Exact distinctions depend on the particular generation and pressure-washer version.

A notable feature of MJJC products is their compatibility with relatively low-pressure machines. The company states its foam guns can produce good foam with pressure washers as low as approximately 90 bar / 1,300 psi, though individual models may have different minimum requirements.[1]

MJJC documentation provides specific nozzle and orifice recommendations based on machine pressure:

• 0.9 mm: approximately 50–90 bar
• 1.1 mm: approximately 90–110 bar
• 1.25 mm: approximately 110–150 bar
• 1.35 mm: approximately 150–280 bar
• 1.65 mm: approximately 280–340 bar

These are manufacturer-recommended ranges rather than universal industry standards.[1] Buyers must select the correct MJJC model and fitting rather than assuming every foam cannon fits every pressure washer.

MJJC primarily serves two overlapping groups.

Automotive detailing professionals

Professional detailers typically value consistent foam output, durable construction, replaceable components, pressure-washer compatibility, faster vehicle coverage, and adjustable foam characteristics.

Car enthusiasts

For home users, the appeal is both experiential and functional. Products are designed to make pressure-washer washing more convenient and visually satisfying, particularly through the dense “snow foam” effect. The company describes its customer base as comprising detailers and enthusiastic consumers, noting that customer feedback plays a significant role in product development.[1]

MJJC positions itself as a specialist rather than a generalist automotive brand. Instead of selling a wide array of items from microfiber towels to polishers and ceramic coatings, the company concentrates on foam-generation technology and pressure-washer accessories. Its slogan, “For Better Foam,” reflects this specialisation.[1]

Although MJJC’s manufacturing and corporate origins are associated with China, the brand has built an international customer base. Company history states that exports to the United States, Europe, and other countries began shortly after the launch of its first product.[1]

MJJC also maintains localised online storefronts, including one for Japan. The Japanese operation describes MJJC foam guns as products designed to connect to household high-pressure washers for car washing.[2]

Within automotive detailing, MJJC operates as a specialist foam-cannon manufacturer. It competes in a market containing OEM pressure-washer attachments, generic foam cannons, aftermarket detailing brands, professional equipment manufacturers, and premium specialists.

MJJC’s strategy differentiates the brand through foam quality, engineering, compatibility, and iterative product development rather than competing solely on price. The company explicitly uses customer feedback to modify products continually, citing “better foam” as a central objective.[1]

Strengths

Based on its documented product history, MJJC’s main strengths include:

• Strong specialisation: Over a decade of focus on foam-lance and foam-cannon technology.
• Product iteration: A clear generational development strategy from Pro V1 to Pro V3.
• Broad compatibility: Multiple fittings and orifice options for different pressure washers.
• Detailing-focused design: Features developed specifically for vehicle washing.
• International distribution: Export operations established since the early years.
• Accessory ecosystem: A complete system comprising foam cannons, shampoo, trigger guns, and fittings.[1]

Limitations

MJJC may not suit every pressure-washer user. Compatibility is a primary consideration; buyers must match the foam cannon to their pressure washer’s connector, operating pressure, and flow characteristics using model-specific information.[1]

Additionally, there is a practical distinction between visually thick foam and actual cleaning performance. While a shaving-cream-like layer is impressive, detergent quality and washing technique remain critical. Finally, as a specialist brand, MJJC does not offer a complete detailing ecosystem covering polishers, compounds, coatings, or towels, which may be available from brands with broader portfolios.

The name MJJC is not an acronym for a technical term. According to official company history, it derives from the initials of the four founders: Michael, Jeremy, Justin, and Calvin. These initials were selected as the brand name upon the company’s establishment in 2011.[1]
