As of this review (2015), NV356E is Amazon.com's number 29 selling upright vacuum. I bought a Navigator Pro for testing when it was released. With its two-in-one breakaway wheel-less canister, for use doing detail work and stairs, Shark's Pro Lift Away is one of the best Sharks ever.ttachments are interchangeable between the regular Shark Navigator Lift-Away Vacuum and the Shark Navigator Lift-Away Pro Vacuum. The Dust-Away Swiffer-like microfiber-cloth covers for the hard floor tool can also be washed (without fabric softeners), but never returns to its hospital-white original appearance.
