Hoover LINX Cordless Stick Vacuum

$134.23 (I own the standard Wind Tunnel vacuum - it is great technology!)
Equipped with Hoover's patented WindTunnel technology, this cordless and bagless stick vacuum cleaner uses the power of rotating brushes and three suction tunnels to lift and trap dirt. The unit's motorized power brush picks up even deep-down dirt in the thickest plush carpeting, while its one-touch brushroll switch on the handle of the cleaner turns off the brushroll, making it easy to transition from carpets to bare-floor surfaces. Move effortlessly throughout the house thanks to the cleaner's cordless design--no more having to stop to re-plug the power cord when moving from room to room. The machine runs on an interchangeable 18-volt Lithium Ion battery, which ensures maximum "fade-free" power right up until the battery becomes completely drained. Its battery-fuel gauge clearly indicates the amount of battery life remaining, while the included Energy Star battery charger quickly and efficiently powers it back up to a full charge. Other details include an 11-inch-wide nozzle with a wide-mouth opening, automatic height adjustment, edge cleaning bristles for closer access along baseboards and corners, soft non-marring rear wheels, and a low-profile base and reclining handle for access under furniture, as well as a comfort-grip handle and the ability to stand upright on its own without needing to lean up against a wall. Lightweight at just over 7-1/4 pounds, the cordless stick vac measures approximately 11 by 8 by 42 inches and carries a six-year limited warranty on the vacuum and a two-year limited warranty on the battery and charger.
