Ok I read the reviews and thought ok I'll give it a try. I live in a very small apartment with my terrier mix dog, Riley. Riley, bless her heart, loses much. I find tufts of hair everywhere. The worst spot was under my bed where my vacuum couldn't reach. I tried an electric broom - unsuccessful in picking up the hair that was stuck to the carpet under my bed - near my head. I really wanted all that hair gone so I thought maybe this contraption would work. MY GOD! Did it work? YUP! I locked him in my bedroom and let him work. In no time at all, the vacuum cleaner picked up almost all of the hair (there's a corner it couldn't reach). I have attached photos. In the first photo, Riley eyed this new pet with particular attention. The second can be picked up in my living room/kitchen in just one hour. The third is my bedroom, covered in Riley's hair that has fallen out. I hope this gets him further. love now!
