I purchased this for a couple of reasons: 1) being a car lover it’s a must for me to have my ‘baby’ sparkling clean. I have 2 air compressors, 6 gal “pancake” & 30 gal. The little pancake is easy, portable & $100. Where I live, I do not have any outside water hookup to my house. I live in Yakima, WA a agricultural community where you get irrigation water instead of city water. (Irrigation here is from snowpack in the Cascade Mtn. Range in Spring, Summer & Fall) We get irrigation water about 8 months ayr. Some ppl may freak I use irrigation water but as I tested it w/TDS meter, it reads same as my city drinking water. So cut to the chase, I hookup the air foamer & use a sudsy bucket & mitt. Yes sudsy bucket, cuz I don’t want to scrub any dirt off my suv if I don’t have to. So how do I rinse when I don’t have outside water? I filled a 5 gal. bucket w/clean water & use a Worx Hydroshot. (A battery-powered pressure washer). I don’t really need pressure to clean, just an easy, quick way to rinse off the soap. Then dry with my Griots towels. Bottom line: I get lots of suds & foam so as not to scratch as I use my mitt, the whole process is fast and easy. AND I save LOTS of water all at the same time.This is a must buy if you want easy, fast, safe for your paint, or want to save water.(No I dont work for Griot’s, Worx nor was compensated for my review)My only negative, the container needs to be larger. Especially for people that own SUVs or trucks, but it’s still a 5-star for me
