This Shark® Lift-Away® comes with a PowerFins™ brushroll, a no-bristle system to deep-clean and pick up more in every pass (vs. original DuoClean®)—all with no hair wrap, thanks to the self-cleaning brushroll. It also includes Anti-Allergen Complete Seal Technology® with a filter to trap over 99.9% of dust and allergens inside the vacuum, keeping them out of the air you breathe.
