Customer Reviews
Great value on a premium cannon
Used a 15% off code from a detailing influencer and snagged the MJJC Snow Foam Shampoo. The build quality is top-notch, especially the brass fittings for my pressure washer. Really impressed with how thick the foam is; it clings well and gives great dwell time for breaking down dirt.
Still my go-to for foamers!
Another order from MJJC, another solid product. Got the MJJC Pro V2.0 Foam Cannon and it's just as good as the last one I had, maybe even a bit better. Shipping felt a little slow compared to previous orders, but saved about 18% with a code so can't complain much.
Great value with a coupon!
The Underbody Cleaner is fantastic, especially since I got it for 25% off with an influencer code. It’s built just as well as the MTM Hydro one I was looking at for $110, so getting this for $67 was a steal. Definitely worth signing up for their newsletter to catch those deals.
Foam Cannon Mesh Filters are a lifesaver!
grabbed some of those Foam Cannon Mesh Filters after seeing an influencer's code for a discount – always great to save a few bucks! they fit perfectly in my Mjjc foam cannon, and my foam is super thick again. i was wondering if their foam gun works with just a garden hose, but after checking, it seems like you really need a pressure washer for the best results. definitely planning to pick up a detailing bucket next time there's a good deal.
quick shipping, solid products
got about 15% off, Nilfisk Adapter showed up in like 8 days to the US, works great.
solid adapter, shipping was a bit slow
grabbed the Karcher K-Series Adapter during a sale last week, got about 20% off with an influencer code. product works great, fit my karcher perfectly. wish shipping from china was faster, but it's not bad for the price.
Good quality, worth the price
Last week I was trying to figure out which MJJC foam cannon adapter I needed for my Bosch pressure washer and after some digging, I ordered the right one. It's well-made and feels durable, definitely a step up from cheaper options. I just wish the shipping was a little faster, but overall, happy with the purchase.

Which MJJC adapter for a Ryobi 1600 PSI pressure washer?
Anyone know if there's a current code for the MJJC Pro V3.0?
Are the MJJC free shipping codes still a thing?
Just got my MJJC Pro V3.0 and trying to figure out the best orifice size for my Karcher K3. Anyone have recommendations for getting super thick foam with a lower PSI washer?
Are there ever any free shipping codes for MJJC, or just the foam cannon bundles?
