The Hoover Platinum Collection LINX Stick Vac gives you cordless convenience with powerful upright performance. It is the first cordless stick vacuum with Hoover's patented Wintunnel Technology, which utilizes three suction tunnels to lift and remove the hidden dirt. One touch activation of the brushroll makes for an easy transition from hard floors to carpets and edge cleaning bristles allow for closer access to walls and corners. The interchangeable 18 Volt Lithium battery ensures that the battery sustains power until completely drained. It even has a battery level indicator that instantly registers remaining battery life. The LINX Cordless Stick Vacuum is ENERGY STAR qualified and includes a Best-In-Class six year warranty.
