I’d use a crb for that carpet 🤔😍😍😍😍😍

To me the green brush is a lil soft on the Oreck but the black brush is a lil stringer stiffer like the one on your drill and that should do the job better and if you look at the motion on the drill it turns in a circular motion clock wise so you are able to in my opinion get at all the carpet fibers in one pass compared to a crb it only digs at carpet fibers in a front to back pass and single caroet fiber is circular not flat with just a front and back it’s round so a drill brush that’s stiff not soft can dig deep and get all the sides of a carpet fiber just as good as a 175 with a black stiff brush not the soft carpet brush one, the 175 with a black brush beats a crb any day of the year
