I have now use this a couple of times and I've been pretty happy.
My only real negative comments are based around the lack of instructions. I wish I had a better understanding of how much soap was recommended. I had to watch YouTube videos to get instructions. Also, the nozzle seems to have three settings, a hard stream which would not make sense unless you were using it as a rinse a fairly wide setting and they totally useless superwide with squirts everywhere. Even with the negative comment about the nozzle I would still recommend this based on the price point and performance.

This foam cannon works great. It is easy to use and adjust. I have tried a few different soaps through it although none of them are made for a foam cannon. It still makes great foam for washing a car, house, etc. Overall I am happy with it and when I run out of my current jug of car wash soap, I will buy something that is made for serious foam out of a foam canon. I fully expect that it will work like a champ but if for some reason it does not, I will update my review.

This thing works great. Covers the whole truck in foam in about 45 seconds. I bought a gallon of Chemical Guys CWS_110 Honeydew Snow Foam Car Wash Soap and Cleanser (1 Gal) and filled the foam cannon bottle about half full believing it would probably go through a lot of the soap quickly being blown out by a 3000psi pressure washer. Wrong ! It barely uses any of the soap at all to cover the whole truck. That gallon of soap is gooing to last me a long, long time. The neighbors saw me using it the first time and came outside to watch - it was so cool. Everybody wants one now. Here's what I did: used the pressure sprayer to knock off most the dirt and sand off the truck. Then hook up the foam cannon and spray the whole vehicle. I then used a sponge to scrub the truck to get off the bugs and tar and stuff, then unhook the foam cannon, and use the pressure sprayer to rinse everything off. Cut an hour off the cleaning time. No need for a bucket. I'm 100% completely happy. And the truck smells like a big Honey Dew Melon. I'm good.

Works well, only used it once. Nicked one star because the plastic drop tube from the valve into the bottle was missing. I had some sprinkler tubing, so I cut a piece off and it fit (a very tight fit). I used it with Chemical Guys pink stuff, which soaped up my car pretty well. The stream isn't too strong - so car paint isn't damaged. As others have noted, the plastic bottle is lightweight and possibly prone to damage, so I'd recommend doing your best not to drop it.

it works as it should.. Its awesome how it covers the car/bike with foam. When I received the sprayer it didn't quite work right , only sprayed foam when unit was upside down. looking at the sprayer head i noticed a nipple where a small hose would hook up to work as a draw straw once i put a piece of hose on it it worked properly. The only complaint other then the missing draw straw is the spray pattern adjustment moves if you don't hold it which isnt really a problem because it literally takes 20 seconds to completely cover a full sized pickup with soap. I like it and would purchase this item again.
