Interesting stuff, I too would like to see the machine performing, ideally next to a standard one with 100' of hose.
To be honest it's extremely rare for me to use anything more than 75' of hose, but I guess it's nice to know you have the added power there if required.
So adding a booster creates 2 pairs of motors in series similar to the escape, I for one witnessed the Escape at last years TACCA event and it was very powerful... Dare I say... More powerful at the wand than my old prowler
