This brush is absolute top class in dog hair. Our new Snuffles has longer fur. The hair implant themselves in the carpet and were previously rauszubekommen with nothing. Tried everything (existing brushes, robotic vacuum cleaner etc.) and finally ordered me despair the Dirt Devil brush. We are absolutely thrilled! Once so our Shorthair carpet and everything is super clean. Since making sucking fun again! However, the brush is only conditionally suited to the small clean walkway carpet which has a somewhat longer pile. As she slows down and you have to really scrub back and forth, so that they can at all turns. It seems to come on to the pile length. Very handy, I also think the transparent hinged lid. You see everything and kanns clean jiffy. Conclusion: Highly recommended for dog owners with short hair carpets.
