Shark Clean & Empty Cordless Stick Vacuum with Auto-Empty System, HEPA Filtration and Self-Cleaning Brushroll, BU3521 White/Peacock

Shark BU3521 Overview

Auto-Empty Docking Base: The bagless design empties into a 0.25-gallon base, so dust leaves the wand without you reaching into the dust cup.
40 Minutes Per Charge: A single charge delivers up to 40 minutes of cordless cleaning, enough to work through several rooms before you dock it again.
Sealed HEPA Filtration: A HEPA filter works with the Anti-Allergen Complete Seal to hold fine dust inside the unit instead of releasing it back into the room.
Carpet And Hardwood Ready: Rated for carpet, area rugs, and hardwood, so you can move from a living room rug to a bare floor hallway without switching machines.
Built-In Headlights: Headlights on the nozzle brighten dark corners and the space under furniture, showing debris on hardwood that room lighting hides.

16.64 lb System

Integrated Battery
Power comes from a non-detachable battery, so charging happens on the unit itself with no separate pack to store or swap.
