Royal Exclusiv offers the same one but they need to be ordered from Germany. They aren't cheap though and cost several hundred depending on whether you want it with the wash down or not. If you are seriously interested in one, send me a PM with your email address and I will get an email going to Germany so we can get you a quote. You won't find a better SCH. I've had mine 5 years now. They actually have a built in wet wiper setup that draws water from inside the skimmer and sprays it over the wiper. It has a small peristaltic roller pump in the motor assembly and pulls the water from inside the skimmer when the motor turns. The washdown for the cup needs to be fed by an external water source. Mine is connected to a hose spigot that I used for my RODI when I had the RODI in the closet next to the tank. It takes some water pressure to make the wash down work well. A regular powerhead won't cut it other than just adding water to the cup. Good tap pressure on the other hand will spray the sides of the cup via the wash down tubing.
I figured it would be expensive. Just out of curiosity, what would be a ballpark figure? I know I won't be able to afford it now, but maybe on my next build.
