The Shark Clean & Empty BU3523 is a cordless stick vacuum whose dock both charges the vac and empties its bin into a sealed base after every clean, so dust stays out of the air and off your hands. It is about 30% lighter than the Shark Vertex Pro and converts to a handheld with a motorized pet tool. Shark rates runtime at up to 40 minutes in Eco mode measured at the hand vac, and the HEPA sealed system traps over 99.97% of dust and allergens down to 0.3 microns. It suits pet owners and allergy-sensitive homes that want hands-free emptying; rivals like the Shark Vertex Pro and Dyson V15 offer more raw suction or longer runtimes but make you empty the bin by hand.

Owners like the self-emptying dock and the light weight, and pet owners report the motorized hand tool picks up hair well. The main complaints are runtime that falls well short of 40 minutes outside Eco mode and the space the dock takes up.
The Shark Clean & Empty Cordless Stick Vacuum returns to its charging dock after each clean. The dock charges the vacuum and automatically empties it into the base, so there is no emptying by hand. A Quiet Mode lets the vacuum dock and charge silently, with the emptying left for later.
The vacuum has an auto-adjusting MultiSurface brushroll. It changes brushroll speed for deep carpet cleaning and engages directly on hard floors. LED headlights on the nozzle show debris around the home. HEPA filtration with an anti-allergen complete seal captures and traps over 99.97% of dust and allergens, based on ASTM F1977, down to 0.3 microns. Allergens here means non-living matter.
The handheld vacuum detaches for cleaning above the floor. It works with a Motorized Hand Tool made for picking up pet hair. The redesigned vacuum is 30% lighter than the Shark Vertex Pro. Runtime is up to 40 minutes in ECO mode, measured at the hand vacuum.
