Customer Reviews
Reliable foam every time
I've ordered from MJJC a few times now, mainly for their foam cannons. This last purchase was for a Pro V3.0 Foam Cannon and some Microfiber Drying Towels. The foam cannon arrived in about 5 days to my place in California, which is pretty standard for them. The quality is always consistent, producing that thick foam I expect. My only minor quibble is the shipping cost feels a bit high for smaller items sometimes, but the product itself never disappoints.
Foam cannon is amazing
Oh my gosh, I just got the MJJC Pro V3.0 Foam Cannon and it's incredible! I used it with their Snow Foam Shampoo and my car looked like it was covered in a cloud. It worked perfectly with my Karcher K-Series adapter. Setting it up was super easy too, which I really appreciated. I will absolutely be buying more accessories from here. Everyone needs one of these! The tracking info could have been a little more detailed, but it arrived quickly.
Good foam cannon, fast shipping
I ordered the MJJC Pro V3.0 Foam Cannon a few weeks back. It came pretty quick, took about 5 days to reach me in California. The foam it makes is super thick, way better than my old one. Made washing my truck a lot easier, though it was a bit tricky to get the adapter connected perfectly at first.
Reliable foam, as usual
Another solid order from MJJC. I picked up a new Pro V3.0 Foam Cannon after my old one finally gave out after years of use. It's just as good as my previous one, foam output is consistent. Shipping was a bit slow this time, took 6 days to reach me in California.
Got the new foam gun
So I finally got around to trying the MJJC Foam Gun for Garden Hose, because I don't have a pressure washer yet. It actually worked pretty well for a garden hose setup, better than I thought it would. My car got a decent wash, not super thick foam like the pressure washer ones, but definitely enough. Shipping took 4 days to reach Austin, which was fine. The instructions were a little basic, but I figured it out.
Got a solid deal on foam
I was looking for a new foam cannon and saw the MJJC Pro V3.0 was on sale. I signed up for their newsletter and got an extra 10% off, which was a nice bonus. The whole purchase felt worth it, especially with the discount. Shipping wasn't instant, but it arrived within a week. I just wish they had even more bundle options to save on accessories.
Pro V3.0 works great
Bought the MJJC Pro V3.0 Foam Cannon. It arrived in 4 days. Easy to use, makes good foam. Happy with the purchase. The bottle could be a bit bigger.
Good cannon, fast shipping
Ordered MJJC S V3.0 Foam Cannon. Arrived in 3 days. Foam was thick. Works well. Bottle feels a little thin, but it does the job. Happy with purchase.

Share tips, ask questions & help fellow shoppers save more
Hey guys, thinking of grabbing a Pro V3.0. How long does shipping usually take to like, California? Don't wanna wait forever.
Can you use more than one discount code at checkout? Got a couple I'm hoping to stack.
What's the deal with returns if I get a defective foam cannon? Is it a hassle or pretty straightforward?
Anyone know if MJJC ever does free shipping? Or like, a good coupon for the Pro V3.0? Thinking of getting one soon.
Anyone know if the Pro V3.0 discount code is still active? Saw something about it last week but can't find it now.
Wondering if the MJJC foam cannon is actually better than like, a Chemical Guys one? Pricey but is it worth it?
Hey guys, thinking of getting the Pro V3.0. How long does shipping usually take to, say, California?
Is MJJC actually legit? I see a lot of knock-offs on Amazon, just want to make sure I'm getting the real deal.
