    • 🧼 Professional-Level Foam Cannon for Serious Car Care Enthusiasts
Style: EQP324
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! ... show more

    • Great Product even with my crappy setup!!
Style: EQP324
Let’s address the complainers and the other reviewers who actually have some facts wrong. Some people complain about the clear plastic cracking when they drop it. That’s like complaining that your fender gets dented when you run into a power pole. Don’t want a crack? Don’t drop it. Simple. The fact that things break when they are dropped is NOT a flaw. It is a fact of life. Some people complain that it’s too expensive for what it is? Really? Then don’t buy it. Nobody is forcing you. The rest of us don’t need to hear your opinions on how everything should come to you on your terms. One guy said that you “had to have the Snubby Spray Foam Gun Attachment.” No. No you don’t. I don’t have it. It works great on my regular pressure washer wand. Granted I’ll probably get a Snubby eventually. But you do NOT have to have it. Lastly, somebody complained that it only works with a pressure washer. Well no poop Sherlock. It’s right there in the description. That’s like complaining that a stand alone freezer doesn’t work as a refrigerator. Here’s a helpful tip. Buy the tool based on what it says it does, not based on what you think or wish it does. Now, my crappy setup. I have really low water flow at my house. It’s an old house. If I hook my pressure washer up to my outdoor spigot, it pulses. Builds pressure then loses it. Over and over. So, I fill a rain barrel with water. On that barrel I have a small transfer pump that moves 3.3 gallons a minute. I use this to feed my pressure washer that puts out 1.4 gallons a minute at up to 1,800 psi. This foam cannon works beautifully in spite of my awful setup! (And at the end of my spray wand too, in case you forgot that you don’t have to have the Snubby!). Do I have a problem with the bottle tipping over or falling? Nope. When I’m done spraying, I disconnect it. You don’t need to continuously go back and re-foam the car. Foam it once and you’re done with the foam. So disconnect the foam cannon and put it safely aside. Easy breeze. And no cracked bottles either! Whoa! Bonus!! Do I think it’s too expensive? No. I bought it and I live within my means. And I respect someone else’s right to make a product and sell it for what they determine is fair compensation for their intellect, time, raw material, and labor. They get to decide that. I don’t. I only get to choose to buy or not buy. I’m I hurt that it doesn’t connect to my garden hose? Nope. But to be fair, I can’t even run a garden sprinkler well from my garden hose. So, there’s that… So, it’s a good product in my opinion. Buy the product that they are selling, not the product you think it ought to be. Do those things and you’ll be happier than all the negative nancies who can only feel good about themselves when they are trying to cancel someone else. Great product. Good value. I’ll buy it again when this one breaks! ... show more

    • Works great!
Style: EQP324
Love it. Creates huge amount of foam that stays on the car until I finish washing. Excellent tool if you like to wash your own car.

    • Foam Cannon Game-Changer!
Style: EQP324
This foam cannon completely exceeded my expectations. The thick foam it produces clings to my car like snow, making washing much more effective and fun. The 34 oz wide-mouth bottle is super easy to fill and mix without spilling, and the quick-connect makes setup fast and simple. I’ve used it on my car, patio, and even my boat—it handles it all. The build feels solid, and the adjustable spray pattern gives me total control. Just be aware that it does use more soap than basic foam guns, but the results are 100% worth it. If you’re serious about getting a deep clean with less effort, this is the one to get. ... show more

    • Great Function; Poor Quality Bottle
Style: EQP324
Review Image by Aaron Reynolds Aaron Reynolds

Overall, this sprayer is fantastic. As most of the reviews state, it’s great. The adjustability, build quality (sprayer only), and foam coverage and throw. I have absolutely loved washing my 4Runner and 2500 HD since I purchased this sprayer. HOWEVER, I dropped the sprayer while washing them yesterday and the bottle cracked wide open at the neck. I was actually quite surprised because the build quality on the actual sprayer portion is so good. It is obviously a cost-cutting decision and there could be some quality control issues with the manufacturer. Regardless, I went to the Chemical Guys website and read several other people saying the same thing happened to them. I’ve owned exactly two Nalgene bottles and have used them every day for the last 10 years. I drop them occasionally and have never had one crack open like the sprayer bottle did. It would be great if a wide mount Nalgene would fit into the sprayer, then problem solved. ... show more
