When I looked at the pictures, I knew that you're the guy with a humongous truckmount. I'm only hoping that this cool thing you're presenting is DIY project( when I was building my splitter I was going for the same material, but went for a cleaner look, which resulted in greater obstruction) otherwise I don't see many guys here paying $ 250 for this setup( splitter and Y). It's nice to have one in arsenal and use it on longer runs. I just like to point out that the biggest advantage of this concept is to be able to get in between rows of chairs ( if there is enough room ) Last summer I've cleaned similar amount of chairs, except that they were scattered in 4 different rooms. Actually that was good thing, because we were falling asleep after 200 chairs and two pizzas. Instead of dual wanding I opted for a combo TM/portable using two recirculating upholstery tools.
