I am going to be trying out an Interior WFP system called the Dragonfly that is from the UK. The version I purchased is the sprayer head that I can mount on my regular carbon fiber pole with a hose that runs down and connects to a water bladder (which you fill off of your pure water system) and battery powered pump that are mounted in a backpack similar to a Camelbak. There is a remote on a lanyard that the operator controls the re-wetting of the pad at the end of the pole.
I originally looked at the Cleano, but it is limited to the length/height be it’s own design. And I read several negative reviews of the Stingray.
I have to clean the interior and exterior of a local car dealership this weekend during the overnight hours, so this will be the test. 275 pieces of glass on the interior and 370 pieces on the outside.
