Meet the cordless vacuum that empties itself, so you don’t have to.
Forget about emptying for weeks at a time
Every time you finish cleaning, Shark Clean & Empty automatically deposits the dirt and debris into a completely sealed base unit that holds it for up to 30 days. No more manual emptying after every clean – simply return the vacuum to the dock and let the hands-free Auto-Empty System empty the cordless vacuum’s dust-cup into a large bagless base. Dust Cup : 0.42 L , AED : 1.3 L
Seals away dust & debris inside the base
Anti-Allergen Complete Seal captures and traps up to 99.9%* of dust, allergens and irritants inside the base*, keeping them out of the air you breathe. Perfect for homes with pets or allergies.
Lightweight & agile
This cordless stick vacuum is 30% lighter** and easy to use. Charging while stored on the dock, your cordless vacuum is always charged, always empty, and always ready for the next clean. Enjoy up to 40 mins of run-time*** per charge.
Perfect for all floor types
The brush-roll automatically adjusts its speed for deep carpet cleaning, and gives you continuous cleaning contact on hard floors. HyperVelocity accelerated suction power delivers powerful cleaning on all floor types. Anti Hair Wrap Technology actively removes hair from the self-cleaning brush-roll as you vacuum, helping to keep it free of tangles.
Handheld cleaning
Detach the handheld vacuum to clean anywhere with the included Crevice and Pet Tools. Easily vacuum sofas, furniture, the car and more, and reach up high with the wand.
*Based on IEC standard 62885-2 CI. 5.14 at 0.3 to 10 microns.
**vs IZ300UK.
***In ECO power mode with non-motorised tool.
