Today we test out the foam cannon (sometimes called foam lance) from MJJC. They have been kind enough to provide me with a free sample of their MJJC Foam Cannon Pro. We are going to compare build quality between the two foam guns, the ergonomics and go and test their foam production. We'll use the Adam's polishes original blue shampoo for our test and my Greenworks 2000 PSI electric pressure washer.
