The Brass Foam Lance is with more Brass Parts inside, and due to the heavier weight and higher cost of brass material, the Brass Version Foam Lance is higher price than Plastic Foam Lance. but the quality are same. only different on material.

Each foam cannon comes with one 1.25mm orifice installed on, and one extra 1.1mm orifice inside the box. So you don't need to buy extra orifice when you order the foam cannon.

Great. It works like a charm.

Good product

İ washed three cars so far with the foam lance and the results are as good as if not better than the self car wash used before.
Main difference being the price of a car wash: 5 times cheaper when doing it with the lance.

Foam Cannon (Snow Foam Lance) for Karcher K Series

Very satisfied and happy

Le meilleur canon a mousse

Excellent produit arrivé en trés bonne état. Manque juste a tester et on verra mais je ne doute pas de sa mousse.

The best foam cannon

This is easily the best foam cannon I have tried. Works great with specialized detailing pre-wash car shampoos, creates lots of thick foam that stays on the car for quite some time.
Highly recommended product!

Better than the expensive foam lance from karcher

It give nice coat of foam on top of my car like snow and it made from brass and the bottle is a heavy duty one so you will not strip the threads very easily also it work great with my Karcher k2 1600 PSI 1.25 GPM and i used the included 1.1mm orifice

Works pretty well.

This is the only way to wash a car. Just spray it on, wait, and rinse it off.mNow if we could just get a wider selection of the soap through MJJC

Its very high quality.

This works extremely well to foam up a car for washing. I had to really crank up the soap/water ratio to get a lot of foam, but then it worked very well with my gas pressure washer.

Love this Foam Cannon. Works perfectly.

Very inexpensive and works perfect. This thing is awesome. I've never seen so much foam.
