Foam Cannon for Pressure Washer (Wide Mouth) - Car Wash Snow Foam Cannon Lance Pressure Washer Soap Dispenser for Car Washing with Adjustable Thick Foam + 1/4 Quick Connector

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!

Product works amazing. Easy to disassemble and address individual issues. Customer service was perfect and one of my products stopped working and I was granted a replacement within two days top-tier company!

I have slowly been building up my automotive detailing arsenal as I wash my own vehicles. This has been a great upgrade! The soap gets evenly spread in a foam all over the vehicle. It’s really easy and smooth to adjust the spray pattern and how much foam you want to come out. Really enjoy getting to use this foam cannon and would highly recommend it to anyone looking to upgrade their detailing game!

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.

Works great. Worth every penny

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.

Big foam

Por el precio al que lo adquirí, es recomendable, genera muy buena espuma. Solo lo he utilizado con HydroSuds de Chemical Guys, agua tibia y una hidrolavadora de 1900 PSI. Es una espuma muy densa.

Make sure you read the instructions correctly before operating this gun and it will give you a great experience every wash👍

Good foam out of the box with my little Chinese 1.55 or 6 L/m washer. Better with 0.9 orifice from aliexpress. Hold enough for one large SUV.
