I highly endorse the Festool Turbo Brush, especially for carpets.
Less than a month before I bought my first CT22, I had purchased a top-of-the-line Meilé residential vacuum cleaner set. That has a turbo brush.
What I same came to prefer about the CT22 is that at low volume when very quiet it cleans as well as the Meilé at full blast. In my condo I dare not run the Meilé much after 6:30 P.M. while I routinely use my CT22 to clean my carpets at 2 A.M. without any complaints.
With my CT22 I bought one of the cleaning sets which included a 36mm AS hose. Not long after that I purchased the Turbo Brush.
People say similar turbo brushes are sold by other firms for less money. As I say, in concept the Meilé seems similar, but it is no as effective. I have no problem keeping my Festool Turbo Brush working, but I do not have any pets shedding air. My own hair was shedded away long before I bought my first CT22.
