The Oreck Axis upright vacuum is designed with 360° Glide Technology, a unique steering ball-joint that makes it easy to steer and offers tremendous maneuverability. This lightweight vacuum weighs about 10 pounds*, is fully-powered with 2 speeds, and boasts a 13-inch wide cleaning path and premium edge brushes. It uses a HEPA inner bag which comes installed. As air passes through the HEPA inner bag it captures at least 99.97% of particles at .3 microns from that air, which includes pollen, house dust, allergens, smoke, pet dander and mold spores. The Oreck Axis is built to last with a 3-year limited warranty**.
