UsIng HyDrox on light blue carpet?

I think a rotary could work for pre-scrubbing and post-bonneting. However you already own a good piece of equipment (your CRB). I learned from an instructor many years ago that the more motors that are running, the higher the perceived value you will have in the eye of the customer. In your case starting off with the CRB, and finishing with a bonnet machine adds a nice touch in the customer's mind. More than that though, it also provides an effective cleaning combination. Don't think of the performing a 2 step system as investing a lot of extra time. Each step becomes easier, faster, more efficient - as you use them together in tandem.

By the way, your English is EXCELLENT.
