Product details
Description, highlights, and specifications from the retailer feed.
Meet the Shark Clean & Empty Cordless Stick Vacuum Cleaner & Auto-Empty System, featuring a redesigned 1.3L auto-empty base and a lightweight design for versatile whole home cleaning. With the auto-empty system, cleaning convenience is optimized so the vac automatically charges and empties when docked, staying Always Charged, Always Empty and ready for the next clean. Inside the base, fine dust and debris are captured after every clean, leaving them out of the air you breathe for less dust exposure. Clean & Empty has up to 40 minutes of runtime in ECO mode, measured at the hand vacuum, with nozzle technology that auto-adjusts to floor type, optimizing brushroll speed for deep carpet cleaning. The Powerfins multi-surface brushroll gives you continuous cleaning contact to dig deep into carpets and directly engage hard floors, and the self-cleaning brushroll technology helps prevent hair wrap on the brushroll.
