S V3.0 Foam Cannon

Upgraded from a cheaper foam cannon and the difference is night and day. The "thicker snow foam" claim isn't just marketing — this thing produces a really dense, shaving-cream-like foam that clings to vertical panels instead of sliding straight off. That extra dwell time makes a noticeable difference in lifting dirt and grime before you even touch the paint with a wash mitt. The adjustable dials for both foam thickness and dilution ratio make it easy to dial in exactly how thick or soapy you want the mix, whether you're doing a quick maintenance wash or a deeper pre-wash on a dirty vehicle. Build quality feels solid too — the bottle and housing don't feel like they'll crack or wear out after a season of use like some cheaper cannons do. The 1/4" quick connector is a nice touch — makes swapping between the foam cannon and other pressure washer attachments fast, no wrestling with threaded fittings every time. Fits snugly and doesn't leak or pop off under pressure. Only takes a couple ounces of soap to get a full car covered in foam, so it's economical too — a bottle of car wash soap lasts a long time. If you're serious about the "foam and dwell" pre-wash method to minimize swirls and scratching, this is a great tool to add to the routine. Highly recommend, especially if you're using a decent pressure washer (1500+ PSI) to get proper foam consistency out of it.

After going through an MTM, a cheap Amazon one, and the old MIJC V2, this V3.0 is on another level. What makes it incredible: • New “Thicker Snow Foam Tech” actually works – produces shaving-cream-level foam with even basic car wash soap (I use Chemical Guys Mr. Pink). One pass and the car is completely buried. • Adjustable foam thickness knob + air intake dial give you total control – from light pre-rinse to absolute blizzard. • All-metal 1/4” quick-connect and brass fittings – no more plastic cracking or leaking after a few months. • 1-liter bottle with wide mouth – super easy to fill and see how much soap is left. • Fits perfectly on my Sun Joe SPX3000, Greenworks 2000 PSI, and Kärcher K1700 – no adapter needed. I’ve used it 15+ times in 90–100 °F heat and it still looks brand new. Zero leaks, zero clogging, and the foam is so thick it just clings forever. If you want the thickest, most satisfying foam possible without spending $120+ on an MTM PF22, this is the one. Hands-down the best foam cannon under $50.

Wow, what a difference! I've been using the MTM Hydro for years and just got used to the design flaws. First it was the bottle that wouldn't stand on its own, that was finally improved, but the fact that I couldn't get more than two or three washes without mixing up some more foam was getting old. I had to adjust it to get a thick foam and thus emptied the bottle too quick. Then I got this MJJC Foam Cannon S V3.0...OMG! This beauty lays down a very rich and thick foam and the best part is I'm getting about ten washes from one bottle. Amazing. It's very easy to set up, but the look and feel of this product just oozes superior design, feel, function and build quality. I gave my two MTM's to my friends that have never had a foam cannon before and bought two of these MJJC's. Which when you think about it, the MTM Hydro may be a good starter cannon, but if you want to go directly to the Porsche (MJJC), then leave the Ford/Chevy to others. It's a no-brainer.

This foam cannon is great! Yes, it is very expensive compared to most, but I had a cheap tool daily foam cannon (also from Amazon) and the foam quality and the spray pattern were less than ideal. This mjjc foam cannon works much better. A couple things I really like about: 1. It comes with smaller diameter nozzle for use with pressure washers with a lower gallons per minute (GPM) rating. I'm using an electric pressure washer with 2400 psi and 1.2 GPM and the smaller nozzle definitely helped produce thicker foam. 2. The pick up tube that goes inside the bottle has a weighted stainless steel ball on the end so no matter what angle the bottle is at it never sucks air. It's a small detail that I appreciate. Overall this is a good buy and performs well, I just wish it was a bit less expensive

A nice upgrade from the previous version placing it more in line with the original pro model. The components are clearly high quality. Produces a nice foam with my Ego pressure washer even when using solutions that have less foaming ability. The size is typical, but the bottle design has some pros/cons. I like the single turn locking mechanism for the lid, which makes opening and closing much easier and faster. However, the bottle has a small base and is very too heavy, so I have had it tip over onto the concrete a number of times damaging the housing. The thinner bottle does make it easier to manipulate the bottle, but I think I would prefer a broader based bottle to prevent the tip overs. I have also had some issues with leaking from inside the spray housing when the bottle is upside down, like when mixing. I have checked the seals and even reassembled everything with tape at the threads but still leaks from inside the housing somewhere.

I have 3 foam cannons and this is by far the best for thick foam.

I’ve used this product a handful of times, and had great results. Thick foam and great for cleaning. That was until I recently went to wash my car, and there is a bad leak happening. Not sure why, I’ve probably used it 8 times in my year of owning it but I cannot get the leak to stop. When spraying, water and foam come out of the nozzle in different directions. For the price point, it’s pretty disappointing.

Loving this product, work perfectly, love the adjustment available and the fact that it connected perfectly to my pressure washer without having to buy extra connectors. I use this to shampoo my jeep after trail riding.

This works great with my power washer, i used my own liquid soap it still works perfect, worth the money.

Great foam canon well worth the money

Does what it is ment to do. But over rated and very pricey. I compared this to a $30 cheap foam cannon with a $5 mod of the insert combination with a metal mesh and a fabric material. What I did not like was the assembly in the lid wasn't locking well and is loose. The breathing hole on the lid made my soap run out. So be aware of that. The mouth of the container is smaller than the $30 cannon I bought. Construction is well made. The bottle is proprietary so no other bottle may fit. Other than the price a nice peice of kit.
