So easy to put together, I never follow directions and you really didnt need them to put this vacuum together which was a big plus for me. The vacuum is lightweight and easy to maneuver. The best part was no cord to deal with. I vacuumed three rooms and still had a great deal of battery power left. The suction is great and good with dog hair. A great vacuum that is easy to use and put together, I am very happy with the Shark Rocket Pro cordless vacuum!!
