Shark Clean & Empty BU3521 Cordless Stick Vacuum, Cordless Design

The vacuum automatically charges and empties itself when docked, sealing away fine dust and debris into the base to minimize dust exposure during disposal. Featuring HEPA filtration with Anti-Allergen Complete Seal technology, it captures and traps over 99.97% of dust and allergens down to 0.3 microns. With up to 40 minutes of runtime in ECO mode, you can clean your entire home on a single charge. The auto-adjusting multi-surface brushroll optimizes speed for both deep carpet cleaning and hard floor surfaces, while LED headlights illuminate hidden debris in dark spaces. A quiet mode option allows for silent docking and charging, with the emptying cycle delayed until convenient.
