Jim's right, they suck as vacuums. On our commercial carpet cleaning this winter we vacuum like crazy, then pile lift, then steam clean or encap. The pile lifter does sit in the garage most of the time, but when you need it, nothing comes close.
Through the years I have owned two Certified Pile Lifters. I agree with the comments above that they are terrible at vacuuming. Mine ended up sitting in storage and not being used too.
When the folks at Kleenrite told me they had designed the vacuum air-path of their X-Vac pile lifter vacuum so that it actually vacuums the carpet, I was skeptical. But I've gotta say - theirs does a decent job of capturing dry soil. It does a lot better than the Certified's did!
It's true, a good commercial vacuum will capture the most particulate soil. However a vacuum cleaner struggles to open up the tightly compacted tuft bundles of a CGD carpet. The X-Vac does a good job of digging down into the pile and prepping the carpet before we clean it. We have one of these on our cleaning van now and we love it.
If i wanted high quality results and didn't mind taking my time, would running a Wittaker crb on the traffic lanes AND then using the X-VAC afterwards pick up a lot of the loose dirt? I am thinking about the first time cleaning in the building.
