Customer Reviews
Foam cannon works great
Got myself the MJJC S V3.0 Foam Cannon and some Microfiber Drying Towels. The cannon is super easy to use, just hooked it up to my pressure washer. It makes a ton of foam, like, really thick stuff. My car looked like it was covered in shaving cream. Drying towels were soft too. Everything just worked as it should, no fuss.
Good cannon, slow shipping
I ordered the MJJC Pro V3.0 Foam Cannon and a Karcher K-Series Adapter. The order process was straightforward on their site. It took about 11 days for the package to reach me in California, which felt a bit long. Once it arrived, assembly was easy. The Pro V3.0 really does produce thick foam, much better than my old cheap one. I used it with some generic snow foam shampoo and it coated the car well. Customer support answered my email about shipping status within 24 hours, so that was fine. The adapter fit perfectly on my Karcher. Overall, happy with the product's performance, but wished shipping was faster.
Decent deal for a first-timer
I was looking for a good foam cannon but didn't want to overspend. I got the MJJC Light S Foam Cannon and a 1/4 Inch Quick Connect Adapter. Found a 10% off code online, which helped bring the price down a bit. Shipping was free, which is always a plus. It's my first foam cannon, so I didn't know what to expect, but for what I paid, it feels like a solid purchase. It does the job for my weekend car washes. Saved a few bucks compared to some of the fancier ones I saw.

Hey, thinking about grabbing the Pro V3.0 foam cannon. Does anyone know if there are any discount codes floating around for it right now?
I've got a Bosch pressure washer. Does MJJC have an adapter for that, or do I need to buy something separate?
What's the big difference between the Pro V2.0 and the V3.0? Is the V3.0 worth the extra cash?
Does MJJC ship from inside the US or is it coming from overseas? Wondering about delivery times to California.
