Kenmore Featherlite Lift-Up DU4080 vs Shark Navigator NV352

Buy the Shark Navigator NV352 for whole-home carpet cleaning and allergy control. It has the stronger motor, a wider cleaning path, a longer cord and a brushroll shutoff for bare floors. Buy the Kenmore DU4080 if stairs and above-floor cleaning matter most: its lift-up pod turns the upright into a 12.4 lb canister, and it runs quieter. Owners of the Shark praise suction and the sealed HEPA setup but report the hose and wand feel flimsy. Kenmore owners like the lift-up design but note suction drops as the bin fills and the seal weakens.

• Choose the Kenmore Featherlite Lift-Up if you clean a lot of stairs and upholstery and want a lighter, quieter machine that converts to a pod.
• Choose the Shark Navigator NV352 if you want the stronger, wider carpet cleaner with a longer cord and a brushroll shutoff for hard floors.
