Shark Rotator Lift-Away NV501 vs Bissell Pet Hair Eraser Turbo Plus

The Shark NV501 is the better all-round pick for homes with both carpet and hard floors, and for allergy sufferers who want a sealed HEPA system. The Bissell Pet Hair Eraser Turbo Plus is the more focused pet-hair machine, with a tangle-free brush roll, a quieter motor and a longer warranty. Both are corded uprights around 15 pounds with 30-foot cords, so the choice comes down to filtration and versatility versus pet-hair handling and warranty.

• Choose the Shark Rotator Professional Lift-Away NV501 if you want one vacuum that converts to a portable pod for stairs and furniture and has a sealed HEPA filter for allergies.
• Choose the Bissell Pet Hair Eraser Turbo Plus if pet hair is your main problem and you want a tangle-free brush roll, quieter running and a five-year limited warranty.
