Love this foam cannon. High quality components, works well, easy to use. I clean everything with it: boat, car, deck, house, etc.

    • 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

    • 🧼 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

    • works awesome but why can't they . . . . . .
Style: EQP324
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. ... show more

    • Great product..but needs improvement. ...
Style: EQP324
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... ... show more
