Griot's Garage The BOSS Foam Cannon Pressure Washer Foam Gun — 33.8 oz Jar, Auto‑Mix Thick Clinging Snow Foam

The BOSS Foam Cannon from Griot's Garage is a professional-grade pressure washer foam gun that produces thick, clingy snow foam instantly with a built-in Auto‑Mix system for fuss‑free detailing.

Engineered for enthusiasts and professional detailers, The BOSS combines durable stainless steel components with a smart, no‑mess Auto‑Mix mechanism so you can foam and rinse faster without measuring concentrates. It ships with a 33.8 oz jar, extra metering tips, and compatibility with Griot’s Garage 22 oz and 35 oz bottles, making it a versatile addition to any pressure washer setup. Built to withstand repeated use, The BOSS focuses on consistent foam coverage and easy adjustment so you can tailor spray patterns for cars, trucks, and larger vehicles like RVs.

How does The BOSS create thick foam without pre‑mixing soap?

The foam cannon's Auto‑Mix system meters concentrate directly from the bottle while you spray, removing the need to pre‑dilute soap. This automatic dilution gives reliable suds every time and reduces spills or wasted product.

• Attach a Griot’s Garage concentrate bottle—no measuring required.
• Internal metering tips tune dilution for different viscosities.
• Immediate foaming as soon as water and concentrate mix under pressure.

Is The BOSS compatible with my pressure washer and bottles?

The BOSS is designed to work with most common pressure washers and includes a stainless steel quick coupler plug for broad compatibility. It accepts Griot’s Garage 22 oz and 35 oz bottles and includes a 33.8 oz jar so you can start using it right away.

• Includes stainless steel quick coupler plug for many makes/models.
• Comes with a 33.8 oz jar and fits Griot’s 22 oz and 35 oz bottles.
• Metering tips provided for gas and electric pressure washer flow rates.

What adjustments control spray pattern and foam thickness?

You can modify both the spray angle and the orifice choice to match your washer type and cleaning task. The adjustable nozzle switches between a concentrated 0° jet and a wide 40° fan, while supplied jets (1.1mm and 1.25mm) optimize flow for gas or electric units.

• Adjustable nozzle gives 0° to 40° spray options for focused or wide coverage.
• 1.1mm jet recommended for gas pressure washers, 1.25mm for electric units.
• Swap metering tips to fine‑tune dilution and foam cling.

How do I keep The BOSS performing at peak levels over time?

Like all foam cannons, The BOSS benefits from periodic servicing to replace worn seals and metering parts. Griot’s recommends keeping a Foam Cannon Rebuild Kit on hand so maintenance is quick and you avoid downtime during detailing sessions.

• Routine inspection of O‑rings and seals prevents leaks and loss of suction.
• Use the rebuild kit (BFKIT) for fast replacement of wear parts when needed.
• Rinse the jar and pump passages after use when switching chemistries.

Who this product is for: The BOSS Foam Cannon is aimed at car care enthusiasts, mobile detailers, and anyone who wants professional‑quality foam coverage with minimal setup. If you own a pressure washer and want faster, cleaner pre‑washes for daily drivers, show cars, trucks, or larger vehicles like RVs, The BOSS saves time while delivering consistent, high‑clinging foam. It's especially useful for users who prefer a durable, stainless steel build and the convenience of an Auto‑Mix system that eliminates pre‑dilution and reduces waste.
