The BDXURV309G Upright Vacuum Cyclonic Cleaning Action rapidly spins debris away from the filter so suction power stays stronger, longer. Empty less often with the large two-liter bagless dust bin. Washable dust bin and anti-allergen HEPA filter for low maintenance costs and thorough cleaning. The 1,200 Watt motor can be operated continuously and reliably with plug in power. No charging or replacement batteries required.
