The Shark Rotator Pet Lift Away ADV Uprights gut Vacuum is a very powerful vacuum cleaner.    It is very easy to assemble and  even easier to 
use.  The lift away function is convenient and light weight when vacuuming stairs.  The hose is extra long and can reach the ceiling and corners with out even stretching.  Picks up my Labrador Retriever’s hair with out an issue and with out clogging.
