Shark Stratos Upright AZ3002 vs Shark Rotator Lift-Away NV501

Buy the Stratos AZ3002 if you have pets, thick carpet or allergy concerns and want the stronger, newer cleaner. It has more suction, a wider cleaning path, a self-cleaning brushroll and odor control. The Rotator NV501 is the lighter, simpler choice with a bigger dust cup and a longer hose, and its long record of owner ratings is solid. Both are corded bagless uprights with HEPA sealed systems; the Stratos is the step up in cleaning power, the Rotator in capacity and hose reach.

• Choose the Shark Stratos AZ3002 if you want the strongest hair and pet pickup, a self-cleaning brushroll and odor control on carpet and hard floors.
• Choose the Shark Rotator NV501 if you want a lighter upright with a larger dust cup and a longer hose for stairs and above-floor cleaning.
