... You have a dog with long hair. Both the animal hair, as well as the long human hair "instant" caught in the brush and bring it to a complete stop. At first I thought it was up to my vacuum cleaner. But since I have an original Dirt Devil, who works wonderfully without animal hair brush, it will probably be due to the brush.
For short hair animal appropriately determined, but at i-haired rate significantly by this brush off!
