i have a cert pile lifter for sale, cheap, if you are interested. nylon brush very nice.I was a 'bonnet' cleaner when it wasn't cool...cut my chops on a Certified Pile Lifter / 175FnR Husky / combination.
The Certified machines, as much as everyone avoids them, would not spit up like the CRB does. They do, however, dig every bit as much debris out of carpeting dry, as I've seen come out of the wad from my vac tank filter bags wet.
I can appreciate the versatility of the CRB though it would be a pain to still have to gather those bunnies after usage.
