Cordless Stick Vacuum with Auto-Empty Base, HEPA Seal, 40-Minute Runtime and Pet Tool – Shark BU3523

This cordless stick vacuum returns to its charging dock and automatically transfers debris into a 1.3-liter base, keeping the vacuum charged, emptied, and ready for the next cleanup. The Shark BU3523 uses a self-cleaning MultiSurface PowerFins brushroll that adjusts for carpet and hard floors while helping prevent hair wrap.

Up to 40 minutes of runtime in ECO mode with a non-motorized tool supports routine whole-home cleaning. A sealed HEPA system traps more than 99.97% of dust and allergens down to 0.3 microns under the stated test method, while LED headlights expose debris. The removable handheld unit, motorized pet tool, and duster crevice tool make furniture, stairs, and narrow spaces easier to reach.
