Out of the box, this was the easiest vacuum to assemble - and so many useful tools to make the job of vacuuming even easier. The parts fit seamlessly, the suction is as strong as advertised, and the vacuum moves easily across my thick carpets and bare wood floors, picking up A LOT of pet hair and dust. I also love the versatility of being able to take the canister off the main vacuum to make cleaning tight spaces even easier. I had a Dyson for the past 8 years and liked it, but was recommended this vacuum by three friends.  I can see why they recommended the Shark brand.  I know I am going to love this vacuum for many years to come.
