Review: 🧼 Professional-Level Foam Cannon for Serious Car Care Enthusiasts - If you're looking to take your car washing game to the next level, the Chemical Guys Big Mouth Max Release Foam Cannon is a game-changer. Whether you're washing your car, truck, RV, or even using it around the house or boat, this foam cannon delivers rich, thick foam and a smooth, satisfying experience every time. Chemical guys have quality products on the market and this foam cannon is no exception. Easy application with the power washer and saves time having to scrub by hand. ✅ Why It Stands Out: 🫧 Huge Foam Output: As the name suggests, the “Big Mouth” design really delivers. The wide nozzle sprays thick, clingy foam that blankets your vehicle from top to bottom. It clings well, loosening dirt and grime before you even touch the surface with a mitt. 🚗 Fits Most Pressure Washers Easily: Setup was simple. It attaches seamlessly to most standard pressure washers (just make sure yours meets the PSI/GPM requirements). Once connected, it’s ready to go—no fiddling with complicated fittings. 💪 Heavy-Duty Build Quality: The 34 oz. bottle is large and made from thick, durable plastic. The cannon itself feels solid and professional, not flimsy like cheaper options. It should easily handle repeated use over the long haul. ⚙️ Adjustable Foam Control: You can control the foam thickness and spray pattern (wide fan vs. narrow stream) with ease, letting you customize the coverage for your needs—great whether you're doing a quick rinse or a deep clean. 🏡 Multipurpose Cleaning: Beyond vehicles, it works great on siding, decks, boats, and outdoor furniture. A nice bonus for anyone who wants to use one tool for multiple jobs around the house. ⚠️ A Few Notes: Requires a Pressure Washer: This isn't for use with a garden hose—you must have a pressure washer to use it effectively. Make sure yours meets the PSI requirements. Not the Cheapest Option: It’s pricier than basic foam cannons, but the performance and durability make it worth the extra cost if you wash your car regularly. ⭐ Final Rating: 5 / 5 The Chemical Guys Big Mouth Foam Cannon delivers professional-level performance with ease of use and excellent build quality. Whether you're a weekend car enthusiast or just want a better way to clean your gear and vehicles, this tool is worth every penny. Once you try it, there’s no going back to a bucket and sponge! Review: works awesome but why can't they . . . . . . - why cant they put a bottom on any of these foam cannons that you can set down and not have it tip over so easy ? Love the product and chemical guys stuff in general - but dang I get tired of it spilling when ever it tips over. When you use this you have it off and on your gun and when you set it down you have to be super careful to place it someplace super flat. Thats my rant, performance wise its awesome, wash a large RV and it sprays all the way to the top no problem. When visiting family I did get to use a competitors that was cheaper and did find it to work very well, but was even narrower at the bottom and tipped over really easy. ## Features - BIG MOUTH MAX FOAM CANNON (EQP324) – Trusted by detailers and DIYers, this pressure washer foam cannon blasts thick, clinging suds to wash cars, trucks, SUVs, boats, and more with ease - WIDE MOUTH DESIGN – The car wash foam cannon has a large fill opening that prevents spills and makes adding soap quick and mess-free; 34 oz bottle holds enough solution for multiple washes - MAXIMUM FOAM OUTPUT – Adjustable nozzle and air injection system of this Chemical Guys foam cannon delivers thick, shaving cream–like foam that clings to surfaces, loosening dirt and grime - VERSATILE CLEANING TOOL – Perfect for automotive washes, boat cleaning, siding, patios, and more; this car foam sprayer safely cleans a wide variety of painted, coated, and sealed surfaces - PRESSURE WASHER FOAM GUN BUILT TO LAST – Heavy-duty construction with stainless steel fittings and durable seals ensures reliable performance and long service life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B091KLW5Y8 | | Best Sellers Rank | #7,700 in Automotive ( See Top 100 in Automotive ) #10 in Car Washing Nozzles & Hose Attachments #115 in Cleaners | | Brand | Chemical Guys | | Customer Reviews | 4.6 4.6 out of 5 stars (1,903) | | Date First Available | April 1, 2021 | | Item Weight | 12.3 ounces | | Item model number | EQP324 | | Manufacturer | Chemical Guys | | Manufacturer Part Number | EQP324 | | Model | Big Mouth Max Release Foam Cannon | | OEM Part Number | EQP324 | | Product Dimensions | 9.84 x 9.84 x 3.94 inches | | Special Features | Wide Mouth Design | ## Product Details - **Brand:** Chemical Guys - **Item Form:** Foam - **Scent:** Unscented - **Specific Uses For Product:** Car Wash - **Material Feature:** Unscented ## Images ![Big Mouth Max Foam Cannon for Pressure Washers, 34 oz Bottle | Thick clinging shaving-cream foam, wide-mouth fill, adjustable nozzle and stainless fittings for cars and home - Image 1](https://m.media-amazon.com/images/I/81XzpyTrc0L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What is the orifice size that comes inside the Big Mouth Max Release Foam Cannon?** A: The Big Mouth Max Release Foam Cannon ships with a 1.1mm orifice. **Q: What PSI level and GPM do I need for the Big Mouth Max Release Foam Cannon?** A: The Big Mouth Foam Cannon works great with as little as 800 PSI and 1.4 GPM (2.0 recommended). **Q: Can The Big Mouth Max Release Foam Cannon be used with a standard garden hose?** A: The Big Mouth is designed for use with your pressure washer.
