Got my Shark the other day ,and had it unboxed and assembled in about 5 minutes.It was very self explanatoryIt has great suction power on carpet and flooring. The pod lifts away so you can do furniture, stairs and anything above the floor. It has two brushrolls, duo clean powerfins that pick up fine dust, large piles and embedded dirt. Hairs does not wrap around brushes.Would highly recommend !
