This came in 3 basic pieces and snapped right together. I never looked at the directions. I am glad it was easy. I have a living room rug that I could never get clean with other  vacuums. This one works great. It just glides over the rug and picks up all the debris. It is a black rug, so it shows every speck. I am so impressed with this vacuum. It also has 2 attachments. I like that you can switch between floor and carpet on the handle instead of bending down to the base to turn a knob.
