Shark Clean & Empty Cordless Stick Vacuum & Auto-Empty System BU3521

Every time you dock the vacuum, the base automatically pulls the debris from the vacuum's dustbin into a larger, sealed container within the base. This means you don't have to manually empty the handheld unit after every single cleaning session, which helps keep dust contained.

The 40-minute runtime is measured in ECO mode, which is best for light maintenance on hard floors. If you are using the vacuum on high-pile carpets or using the maximum suction setting, you should expect the battery to drain significantly faster.

Yes, the PowerFins brushroll is specifically engineered to actively remove hair as you clean, preventing it from wrapping around the roller. While it is highly effective at managing long hair and pet fur, you may still need to occasionally clear debris from the brushroll if you have pets that shed heavily.

Absolutely. The multi-surface brushroll is designed to transition seamlessly between floor types without needing to swap heads. It provides consistent suction on hard surfaces and agitates carpet fibers to lift embedded dirt.

The unit weighs 11.24 pounds, which includes the weight of the base and the stick vacuum itself. While the handheld portion is lightweight and easy to lift for above-floor cleaning, the overall system is substantial enough to feel sturdy during floor use.

Yes, the combination of HEPA filtration and the Anti-Allergen Complete Seal ensures that 99.9% of dust and allergens are trapped inside the vacuum rather than being exhausted back into your home's air. This is a significant benefit if you or your family members suffer from indoor allergies.
