Shark IX141 Pet Cordless Stick Vacuum vs Shark Rotator Lift-Away NV501

Buy the NV501 if you want the strongest deep-clean on carpet and the best allergen control; its 1,200 W corded motor, sealed HEPA system and 0.9-quart cup beat the IX141 on raw cleaning and capacity, and 7,200 ratings at 4.6 back it. Buy the IX141 if you need cordless reach for quick daily pickups, stairs and above-floor messes. The IX141 is lighter to carry and runs up to 40 minutes, but its 0.3-quart cup fills fast and the battery is not removable.

• Choose the Shark IX141 if you want a grab-and-go cordless for quick cleanups, stairs and above-floor dust, and you can live with short runtime and a small cup.
• Choose the Shark Rotator NV501 if carpet depth, pet hair and allergy control matter most and you don't mind a cord and 15.5 lbs.
