Bests & Worsts Reviews from Amazon

Need vacuum with motorized carpet head to pick up long white hair from my 2 Great Pyrenees dogs. The suction is exceptional on this vacuum, best of any brand I have ever used, from cheap to expensive. It DOES NOT throw anything out the back onto my feet from carpet or bare floor as every previous vacuum has, very important. It does suck up throw rugs, so I have to stand on them as I vacuum. All my floors are hardwood with a few large carpets. The only issue that I have with it so far is the amount of dog hair that stays on the roller brush. When I used it at the highest level, which sucked up an enormous amount of dirt, the roller was jam packed with hair. It didn't seem to affect its performance, but I did stop to clear the brushes frequently. When I used it at the first level not as much hair stuck to the brushes. However at this level it took many more passes over the carpet to get all the hair. The cup is small, but I knew that when I purchased it. Each time I emptied the cup there was not much dog hair in it, but it was full of dirt. It is lightweight and self propelled and I have to hold it tight to keep it from racing across the floor. This is not a bad thing since I have been struggling with a heavy non self propelled Bissell Smart Clean upright for the past few years, which I thought did a great job, but this Shark is way better. If anyone has a solution for the hair sticking on the brushes, I would appreciate hearing from you.
