Shark Navigator Lift-Away Speed vs BISSELL PowerForce Helix

The Shark Navigator Lift-Away Speed is better than the BISSELL PowerForce Helix. The Shark feels better built, incurs virtually no recurring costs, has an allergen-trapping HEPA filter, and delivers significantly better performance on bare floors. It's also much easier to maneuver, with a 'Lift-Away' design that enables you to pick up and carry its canister body independently of its upright portion. This design makes it easier to clean countertops and shelves with its wand and selection of attachments. Conversely, the BISSELL has a larger dustbin and weighs less. Its floorhead also offers five levels of height adjustment, unlike the Shark's fixed-height head.
