Absolutely love this vacuum! Shark is a brand I trust and was not disappointed with this item! It is on the heavier side, but I like that it is sturdy and feels reliable when in use.  I definitely love the hair wrap prevention since my hair sheds and would always wrap around the rollers on our old vacuum. The soft roller before the main one helps pick up dust and dirt particles and really makes for a clean floor!  The hose has several different end pieces which help get to smaller places and make it easier to vacuum the couch, and the odor neutralization on the couch is awesome! This is a great buy!
