Frequently asked questions
What does Factory Refurbished mean?
The unit has been professionally inspected, tested, and restored to full working condition. It may show minor cosmetic marks, and it is backed by a 90-day warranty unless otherwise stated, making it a smart way to get Shark's top cordless for less.
What is Clean Sense IQ?
An infrared sensor detects dirt you cannot see and automatically boosts suction, delivering up to 50% better dirt pickup versus ECO mode, with an indicator that shows when floors are clean.
How long does the battery last?
Up to 50 minutes of runtime in ECO mode, and the battery is removable so you can charge it anywhere in your home.
Is it good for pet hair?
Yes. The DuoClean PowerFins HairPro two-brushroll system digs into carpets and engages hard floors, and the self-cleaning brushroll prevents hair wrap. Shark states no cordless vacuum picks up hair better.
Can it clean under furniture?
Yes. MultiFLEX technology lets the wand bend to reach under sofas and beds, then fold over for compact, freestanding storage.
How do I monitor battery and power settings?
An LED display gives real-time readouts to monitor battery level, select suction levels, and engage Clean Sense IQ.
How powerful is it?
HyperVelocity Plus technology delivers the most suction of any Shark cordless stick vacuum (per ASTM F558, measured at the hand vacuum in Boost mode), driven by a 309-watt motor.
