Since we moved to this house, we have been using a regular vacuum, thinking our carpets were clean. We were so wrong. The first time we tried the shark powerdetect corded ultra light we got shocked. The photo showing the dust cup almost full, was after less than 3 minutes vacuuming our living room! It was full either way cat hair (you can see him in the picture!), debris and dust. The suction of this vacuum is like nothing we have ever seen before. The handle is firm, but you dont have to put much pressure because it literally guides you. It also coles either an odor neutralizer cup, which makes the room have a very delightful clean scent. 
We are extremely please with this product. We have a 6 month old who will soon start crawling, so to have this vacuum gives us a sense of peace of knowing our carpets are fully clean. Thanks you so much!!
