With the previously used universal nozzle for hard floors and carpets, the hair was usually shuffled just before the nozzle because the art bristles were too hard. The hair could therefore be completely sucked only by lifting the nozzle. The horse hair are substantially more elastic, so that the dog hair are drawn without lifting the nozzle.
It can also be smaller rugs with Rosshaardüse suck easily. Thus, the annoying nozzle change unnecessary. The horsehair hard floor is well made and fits through the adjustable tube holder probably pretty much on every vacuum cleaner tube. I would recommend this product without restrictions.
