Many people new to the business want to know how big their surface cleaner should be based on how large their machine is. There is only one 36 inch surface cleaner that I am aware of that will operate correctly with a 4 GPM pressure washer. That is a Turbo Twister with a 6.5 HP. I had one of my subs use it back in the day when all he had was a 4 GPM hot unit. I used one of these once and I was amazed that with the Turbo I was able to clean just as fast as a 8 GPM unit. Since the motor is spinning the unit, no pressure, no volume of water is being used to spin the wands.
Now these units are heavy, they are pricey and maybe too bulky or to large for your needs, but they will work with a 4 GPM and spin the wand up to 4,000 RPM’s with the right ratio. That’s about twice as fast as a non-motorized surface cleaner that you can by at Lowe’s or your favorite big box store.. The company who built them had a fire and destroyed their business. They did not rebuild since the owner, Glen was over 70 years old. I remember Glen, he always said…YES Sir when you talked with him. He is a pilot as well. Good man.
The turbo twister is just one of the many reasons why we can clean a 280,000 sq ft garage with FULL Reclaim and FULL Filtration in a single day. Thus allowing the Client to open their garage that much sooner, which means more revenue and less issues and a whole lot less of inconveniences to their customers that use the garage daily. The Turbo Twisters allow the speed and deep cleaning that most surfaces cleaners are just unable to accomplish.
Too large of a surface cleaner will not be very effective or efficient. Many new to the business make this mistake regularly. Actually a 20″ is too large for 4 GPM you would be more effective and efficient with a 16″ surface cleaner. Bigger is not always better if not sized correctly.
Speed with our 36″ surface cleaner is heel to toe running 8GPM…3/8’s hose – test it out yourself and see what speed works for you!
