First off this vacuum has amazing suction! Goodbye Dust! Like a Tornado sucking up every bit of dirt! The extension and has that super suction also. What a powerful tool. The vacuum races around like it is a two year old on a sugar rush which was great for me but my disabled client tried it and it was a little hard for him to pull it back, he decided to let it pull him in circles around the room,  which worked out :) My only complaint and why its not 5 stars is because I have been spoiled by automatic cord rewind.
