I loaned my Rianbow D-2 to my brother and his wife a few years ago, and as a thank you they had the power nozzle tuned up for me. The man that they took it to replaced my Vibra Groomer with a generic all brush plastic thing that doesn't do a good job on my carpeting.
Though I only use this machine a few times a year I would like the P/N to the job I intend it to do when I is used. I found a Vibra-groomer II online but it is quite different from the original brush roll. Are they pretty much interchangable as long as they are 12 inches?
