Features
- Wide Mouth Design: The wide mouth bottle allows for easier dilution of soap. The wider bottle design providers a more stable base and prevents the foam cannon from falling over like other designs.
- Superior Cleaning:Thicker foam allows your car's paint to get a deep and delicate cleaning for a beautiful shine. Dirt and other surface contaminants are loosened and the foam adds extra surface lubrication which helps prevent swirl marks as a result of washing.
- Durability: The connectors are made out of high quality brass to withstand high pressure. The bottle is made of strong plastic and is also translucent; allowing you to see the remaining cleaner in the bottle.
- Adjustability: The amount of foam output can be adjusted using the control knob on the top of the foam cannon. Furthermore, the angle of output is also adjustable, allowing you to change the width of the foam stream. Adjust the thickness of foam to your liking.
- Why Us: Outputs amazing foam with both electric and gas powered pressure washers. Built with real copper and brass fitting, not cheap recycled metal like cheaper alternatives. Translucent bottle allows to you see the soap level, unlike others. More durable and leak resistant. High quality materials like the stainless steel quick connector.
- 1-Year Residential Warranty We stand behind what we build, so you can continue trusting us to make your washes more enjoyable. (2025 Update)

This is a good foam canon. I got to use it to wash my car last weekend and the foam sprays very thick and far. It doesn’t have a super wide spray area but it works fine since you can back up from the car to cover a wider area if needed. It’s plug and play to use good product.

Great quality product. The nozzle is hefty with options to change the width of the spray and how much foam you want. Very easy to use and change settings on the fly. The bottle itself is fairly large for holding a good amount of soap. I have experienced no leaks using this. Overall it operates great and its durable.

The foam cannon works really well. I like the two adjustments provided, which, with the right mix of foaming soap, allow me to dial in the amount of foam flowing onto the vehicle. This is definitely a great value and works as advertised.

As a car enthusiast who takes pride in keeping my vehicles spotless, I’ve tried a few foam cannons, but the McKillans Foam Cannon (Wide Mouth) with 1/4" Quick Connector has blown me away. This thing turns car washing into a satisfying, professional-grade experience that’s honestly kind of fun! The wide-mouth design is a total game-changer – filling it with soap (I used about 4 oz of Griot’s snow foam with warm water) is a breeze, no funnel needed, and the translucent bottle lets me see exactly how much solution is left. I hooked it up to my 3000 PSI pressure washer and the McKillans Swivel Gun Pro, and within 2 minutes, my SUV was blanketed in thick, shaving-cream-like foam that clung like a dream. The adjustable knob on top lets me dial in the foam thickness perfectly, and the spray pattern nozzle shifts from a wide fan to a narrow jet for tackling stubborn spots like wheel wells. The build quality is top-tier: brass and copper fittings feel sturdy, and the stainless steel quick connector snaps on without a hint of leaks. I’ve used it on both my electric and gas-powered washers, and it performs flawlessly with both, delivering consistent foam even at lower pressures (around 1800 PSI). The wider bottle base keeps it stable when set down, unlike some flimsy competitors I’ve owned. Plus, the 1-year warranty gives me peace of mind that it’s built to last. This cannon makes washing faster, easier, and way more effective – the foam lifts dirt like magic, reducing swirl marks and leaving my paint gleaming. For anyone serious about detailing, this is a must-have. Five stars – pairs perfectly with my McKillans gear for a showroom shine every time!

Worked as expected. With so many options on the market, tried to find one in the middle cost wise. So far so good. Only used it once but pretty happy with it so far. Let’s see how long it lasts. The quality seems better than a cheaper one I had. The cheaper one, the knob would move during use, causing the foam to stop (just water would come out). I like that it’s a wider base so the bottle doesn’t topple over when placed on a flat surface. Put out more foam than my previous one. My previous one was a brass/metal top that over time stripped the threads on the bottom. With this cover being plastic like the bottle, hoping it lasts longer. Overall, I would buy again. Not the cheapest and not the most expensive so felt it was a safe choice.

The McKillans Car Wash Foam Cannon is an absolute game-changer when it comes to car washing. As a car enthusiast who takes pride in maintaining a clean and spotless vehicle, I can confidently say that this foam cannon has exceeded my expectations in every way. The foam generation capability of this foam cannon is simply outstanding. With just a few sprays, it creates a thick and dense foam that clings to the surface of the car, encapsulating dirt, grime, and other contaminants. The foam not only looks impressive but also acts as a lubricant, providing a gentle touch to prevent any potential scratches during the wash. One of the standout features of this foam cannon is its adjustable foam thickness. With a simple twist of the dial, you can easily control the concentration of foam, allowing you to adapt to different cleaning requirements. Whether you're dealing with light dust or stubborn mud, this foam cannon delivers the perfect thickness to tackle any level of dirtiness. Another aspect that I appreciate is the convenience of the 1/4 quick connector. It ensures a secure and hassle-free connection to the pressure washer, eliminating any concerns about leaks or compatibility issues. Setting up the foam cannon is a breeze, and I can quickly switch between different cleaning tasks without any interruptions. Durability is also a notable attribute of this foam cannon. It is constructed with high-quality materials that withstand regular use and exposure to water and cleaning agents. I have been using it for several months now, and it continues to perform flawlessly, showing no signs of wear or deterioration. In conclusion, the McKillans Car Wash Foam Cannon has revolutionized my car washing routine. It consistently delivers exceptional foam, provides versatility with adjustable thickness, offers a convenient quick connector, and exhibits remarkable durability. If you're seeking a professional-grade foam cannon to elevate your car washing experience, look no further. I highly recommend the McKillans Car Wash Foam Cannon for its exceptional performance and impeccable results. Please note that this review is based on my personal experience and satisfaction with the product. Individual results may vary depending on specific preferences and circumstances.

Purchased as part of a kit that ingluded the gun and wand to go with the foam unit. Connects with no isses to my new electric power washer. Purchased after returning a hose based "foam cannon" that just had zero pressure and hardly any foam. For the price of a few months of my existing car wash plan, invested in a new 2500 psi electric power washer, and this setup to go with it. The quality of cannon setup is first rate. Feels solid. The wide mouth makes filling up super simple. Getting the right ratio of soap to water is trial and error and personal preference. I probably purchased 5 different kinds of soap for foam cannons to try out, some smell really fruity, others say they bead water. In the end I mixed a few kinds , added water, shook up, and foam away. The kids are fighting over who wants to wash the car now. The adjustable nozzle lets you set the width of the spray pattern, and the twist knowb regulates the amount of foam, again personal preference. We keep filling it up over and over just to soak the SUV with foam as there is just something oddly satisfying in using this thing. It works exactly as I would expect, tons and tons of foam, and surprisingly lasts quite a while before I have to refill it. On a small car, one fill would likely get the job done- on our SUV we usually go through 2 fills. The wand attachment that came to rinse with in the kit, easy to attach and detach. Used the pressure washer tips from my washer with the wand and they work as expected. The trigger gun that also came with my kit has a very solid feel, great trigger action. Mine came with the swivel connector so the gun can rotate independent from the hose and won't kink or bind up. Made sure to clean it out as I read elsewhere so it does not gum up as some of the soap I used was "sticky" and thick. Would definately purchase again, I researched other setups and this one has some of the best reviews, and I would agree with them.

Foams and performs well. Four stars because the bottle imploded when it was nearly empty. I avoided this by not letting the soap empty out before stopping. It would be nice to have a horizontal spray adjustment. You can turn the bottle on it’s side, but that only works if it is full.
