Yes but to get it to work you need to get it into contact with the soiling, which means agitating!!! Everything works "on contact", it won't work fro mthe shelf in the back of your van
I personally don't buy in to the theory that you need to agitate some things otherwise they won't work, nor do I believe that that you don't have to agitate some other things and they'll work just as well. It's illogical!!
Agitation is dictated by the combination of carpet type and soil conditions, nothing more nothing less!! I sometimes barely agitate a microsplitter..... I sometimes agitate like hell with m-power!
But going back to your original point Russ, Steve has hit he nail on the head really - the Duo is probably the most frequently used machine I use on domestics - they'dhave to be a real stinker to get the rotary out.
And if I was using the rotary and forced to only have one type of brush I'd have the stiffer polyprop brush, rather than the shampoo brush. You'll find the shampoo brush won't restore matted down polyprop pile as well, and won't get it lifted in the traffic lanes so you can extract it properly. That's really the only time I get the rotary out on a domestic, trashed polyprop. The duo does the rest.
A bigger CRB machine would probably do the job of both
