i have a black car and have washed it 2 times with it and i basically have to change my underwear everytime i do it. its so easy and actually fun, plus best of all it works. best 18 dollars i ever spent. the only thing is that when it sprays the filtered water it sprays slow (because its going throught the filter) and it takes a while to rinse the car and all the cracks. but other than that i love it. definatly a great investment especially for around 20 bucks usd.
idk if anyone knows this because i didnt, but it has 3 stages. it has a nice stream for rinsing, you can fill it with soap and set the dial to suds and it sprays the soap on for you, and then it has the filtered final rinse. i just thought it was the final rinse with the filter. no bucket of soapy water anymore. plus it has an on off that actually works with the flip of a thumb
