I finally made the switch to a foam cannon and it's totally worth it. I never liked the idea of repeatedly going back to the soapy bucket, regardless of using a separate rinse bucket, as the thing always ended up dirty which meant I was putting dirt unnecessarily back onto the car. Dirt = scratches. This way the foam can start displacing the dirt even before there's any agitation. The Gyeon Foam did an amazing job of foaming up with my el cheapo foam cannon. In my personal opinion, I'd rather spend $$ on good soap than on a fancy cannon. The car came out super clean and it was far less time than a traditional wash. This will be my go to for "big washes" with regular "wipe down" washes to maintain the clean. Just do yourself a favor and read the instructions first. It's easy to miss that you are supposed to dilute this product before hitting the car with it. (at which point you're just wasting Foam)
