Shark Rotator Lift-Away NV501 vs Shark PowerDetect Speed Clean & Empty Pet Pro

The NV501 is the stronger pick for deep carpet cleaning and whole-home work. It is a corded upright with a sealed HEPA system, a 9.5-inch cleaning path and a lift-away pod that turns it into a canister for stairs and upholstery. The PowerDetect is a cordless stick: lighter, quicker to grab, with a self-empty base and a 60-minute rated run time, but a narrow 8.3-inch path and a small dust cup. Owners of the NV501 praise suction and the lift-away design but call it heavy and loud; the PowerDetect wins on convenience, not on raw cleaning depth.

• Choose the Shark Rotator Professional Lift-Away NV501 if you have mostly carpet, pets or allergies, and want corded suction that never runs out of charge plus a sealed HEPA system.
• Choose the Shark PowerDetect Speed Clean and Empty Pet Pro if you want a light cordless vacuum for daily quick cleans and a base that empties the dust cup for you.
