I've tried 3 different foam cannon with my pressure washer (by major name brands) and was disappointed with them all. Either they were way too loud or didn't make enough foam. I finally found one that was real good, powerful, made a lot of foam, AND was pretty inexpensive (compared to Adams, Chemical Bros).

I have no affiliation with the company at all (I promise), but I found this Rydell foam cannon it at Amazon and paid under $50. Now it's on sale for $37.97. Yes, I'm a little pissed that I didn't get it at that price, but I've emailed them and asked for a refund of the difference (fingers crossed!). Either way, it's definitely worth the $38 bucks.

 

Neat.

Might get one for my electric pressure washer.

 

I was actually surprised how well it worked for a cheaper semi-off branded item. But it actually did a real good job with my pressure washer (which isn't a super expensive washer either).

 

I bought this one and have used it 3-4 times. So far it has worked really well.
