Easy to operate
I no longer have to wipe down my car after washing it! This system leaves my paintwork spotless—free of streaks and water spots. The bypass valve is a major plus, making it easy to switch between a standard wash and a spot-free rinse.

Highly recommended
The wheeled cart is incredibly convenient and easy to maneuver. The bypass valve design is practical—no need to disconnect hoses when switching modes. Thoughtful details like these make a big difference. No more worrying about water spots after washing! The deionized water delivers amazing results, leaving the car body mirror-like and shiny. Hassle-free and professional.

Positively surprised at how great it works
After first window washing I will say this is the real deal. I also purchased the telescoping pole which together these two work together nicely. The pressure is great and it literally took our water from 300+ particles per million down to 0. It dries crystal clear and is very easy. Hopefully the filters last a while.

Stress free washing!
Great product. It does what it says. With this, you can do a better job than any car wash. Get yourself a cheap water particulate tester so you know when to change the filters. When they’re new you can literally just wash and walk away. I still do a rub down with a ceramic wax but there’s no need to rush. I wash my truck and wife’s car and the filters lasted about 7 months. I had one of gaskets tear and Nick from product support is sending me a whole new set no charge!

Was good
Bought this for my black corvette I used it only about 9 times and always used the the bypass valve while washing and rinsing the car and only the final rinse did I turn on the filtered water and it worked GREAT untill it didnt !!! Now here I am a few months later and only 9 rinses and it’s no longer filtering the water and the replacement resin cartridge is almost $200 to replace really wish it lasted for more than 9 rinses crazy to think it costed over $40 per rinse using this filter. I went from telling all my friends and family about what a AWESOME cleaning tool I got to being very disappointed with this purchase should last longer and be cheaper to replace the cartridges
