This vacuum is the MOST dependable appliance you can invest in w/o any  disappointments.  Before assembling the Shark Navigator, I vacuumed my floors with my Shark Professional Rocket, not only did the Shark Navigator Lift-Away ADV get even more debris from my carpet but even pulled the carpet Up more so and fluffy. Having this vacuum is like having 2 vacuums in 1, because it does break down so that you can vacuum ceilings, stairs and furniture with total easement because of the lightness of the vacuum. SHARK is the go to vacuum where disappointment is NEVER experienced. And you don’t need to purchase disposable bags to use. A great investment w/o ANY disappointments.
