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!

So much better for cleaning my car
Went from a hose based foam cannon to a cheap pressure washer foam cannon, and neither were nearly as good. The valve and nozzle are solid, bit hefty, but not really a problem when using it. The plastic doesn't feel cheap and it easily connected to my pressure washer. The soap and nozzle adjustments are great, no issues with either so far, and both are easy to use. The foam definitely stays for much longer and covers my car far better than any of the other cannons I've used. It also used far less soap than what I've gone through using other cannons which is nice (I use ceramic based, so spendy). Definitely recommend as an upgrade if you like to wash your cars or if you're starting to get into car washing and detailing. Looking at buying their pressure washer next as I'd like to stop using my gas powered one.

Great product..but needs improvement. ...
I like to wash my cars at home. I don't like the fine scratches some car washes leave on your cars surface...especially if the car ahead of yours looked like it wasn't washed in months...all that dirt trapped in the felt or microfiber fingers of the brushless carwash wind up on your car in some way shape or form. I have plenty of other foam cannons. Mostly from a competitor, but wanted to give this a try with the wide mouth feature of this particular cannon. Out of the box, it worked great, but I noticed that the pressure washer would strain a little when pressurized water was passing through the cannon. The range of PSI this operates is wide, so I can see why the strain. The cannon works best with low PSI pumps, according to a few other people I spoke with. One thing good and bad with this. The container. Good: Wide opening, clear and easy to see how much soap you are actually putting in to mix.. No spills or drips...very nice.. Bad: The container is hard plastic and if you drop, lay down the cannon too hard, or if it falls accidentally, it will crack. I have a hook on my wash bucket i hang my cannon on when I'm washing the car by hand. I went to shut off the pump and knocked the bucket in the process. The cannon fell, no more than 18-20" and at the right angle, cracked the container, rendering the cannon useless. The hard plastic has its good points and bad, this one being the bad one. I returned / exchanged the cannon for a new one, and now will disconnect the cannon from the pressure washer to avoid damage. Other cannon manufacturers containers are made from a different opaque plastic, softer, which doesn't really give you an idea of soap to water mixture, but the trade is it won't break or crack with dropped or fall to the ground in short distances. I've accidentally dropped those as well, no issues.. Overall, a great product, but remember to use care when handling the container...and remove it from the pressure washer trigger when not in use to prevent any accidental damage...

Stands apart from generic cannons
My no name, Amazon special cannon quit on me, so I grabbed this one. I personally feel like it’s worth the money, here’s why: The foam is different. Using the same power washer and amount of soap s my other cannon, the foam was way thicker and the residence time on the paint was drastically increased. I use an 1800 psi electric washer, produced a crazy about of foam for that pressure. Likewise I can already see that I will use less soap. I have gallon sizes of all my detailing stuff, including the CG Citrus Wash and Gloss. I used two pumps to the cannons reservoir, but I will use less next time for sure. There’s is no disputing that the cost is 3 times the cost of some of the others; I can’t say it will be worth it for everyone but it is for me. I work in an industrial manufacturing plant with fallout that can really damage paint. It means a lot to me that most times I can wash my vehicle without actually touching it and as a result introduce work marks. It works as described and really does produce thicker foam than my other cannon. Also factor in the wide mouth opening of the reservoir makes filling and cleaning a breeze.

It is a foam cannon until it breaks
I bought this thinking it would have some advantage over other options. This is more expensive, does a similar job to less expensive options and the cap will break. The wide bottle mouth is a minor plus, but for the cap having a design flaw. I can't recommend this when there is no reason to.
