The Shark® Wandvac® Self-Empty System is incredible. It's very powerful. I love how lightweight this cordless vacuum if and the fact vthat empties itself. The HyperVelocity® suction power and PowerFins® brushroll tackle floors & carpets with no hair wrap. Again, the best feature is that the Wandvac® automatically empties into a HEPA-sealed base for up to 100x less dust in your home vs. traditional emptying. This product is amazing and I highly recommend this product.
