I would absolutely recommend this product to anyone who has an outgoing dog. I have a German Shepherd that sheds like no other. Well I was a bit skeptical about this product but it is amazing. If your dog doesn't like the vacuum, start by getting him used to it. If you have a cordless vacuum then it doesn't have to be on all the time, just use the suction power every few brushes. There are about 10-12 strokes in this picture. I will definitely use this product everyday to groom my dog and save my Roomba all the work. 10 out of 10
