Great Product even with my crappy setup!!
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!

🧼 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!

Es un buen producto, la verdad esperaba un poco más, pero cambiaré el producto de lavado para que generé mayor espuma, quizá es lo que fallo.

فوم قن ذو مواد تصنيع سيئة للغاية وبسعر مبالغ فيه نحو 100$ أنصح بالشراء من شركة "ناكو ديتيل" جودة صناعة برازيلية متوفره عند وكيلها بالسعودية "Superiorcaresa"

I recently purchased the Chemical Guys EQP324 Big Mouth Max Release Foam Cannon, and it has completely transformed my car washing routine. This foam cannon is a game-changer, and I couldn't be happier with the results it delivers. First and foremost, the build quality of this foam cannon is top-notch. It feels sturdy and well-made, ensuring that it will last for a long time. The "Big Mouth" design makes it incredibly easy to fill with soap, minimizing any mess or spills during setup. When it comes to performance, this foam cannon truly shines. The foam it produces is thick, rich, and clings to the car's surface like a dream. It's not just about creating a satisfying foam show; it actually helps to lift dirt, grime, and contaminants from the car's paint, making the washing process more effective and efficient. The adjustable spray pattern is a fantastic feature. You can customize the foam output to suit your needs, whether you want a broad coverage or a more concentrated stream. It's a versatile tool that works well for both maintenance washes and deep cleaning. One of the standout features of the Big Mouth Max Release Foam Cannon is its impressive soap-to-water ratio control. You can easily dial in the perfect mixture, which not only saves on soap but also ensures a thorough and economical cleaning process. Cleaning and maintenance are a breeze with this foam cannon. It disassembles quickly for easy cleaning, and Chemical Guys provides clear instructions to help you keep it in top shape. In summary, the Chemical Guys EQP324 Big Mouth Max Release Foam Cannon is an exceptional product for any car enthusiast or detailer. Its robust construction, outstanding foam generation, and adjustable settings make it a must-have tool for achieving professional-quality car washes at home. I highly recommend it to anyone who takes pride in keeping their vehicle looking its best. This foam cannon has certainly earned its place in my car care arsenal.

Works exactly as described with no issues whatsoever. I'm using 4 oz (instead of the recommended 2) of chemical guys foam wash and it coats my entire truck with thick foam no problem. If you follow the products directions, use a decent pressure washer, and a quality soap you will not be disappointed. Little pricey for what it is but after reading many reviews and watching numerous videos I decided on this one for quality and longevity.
