The Tornado Zephyr Cordless Backpack is a 3 qt. cordless vacuum built for commercial cleaning crews that need a lightweight, cordless backpack unit. It's constructed from expanded polypropylene (EPP), the same lightweight, sound-insulating material used in sports equipment and aerospace, and weighs 7.3 lbs without the battery, 11.4 lbs with it installed.

The Zephyr runs on the Tornado Cordless system's interchangeable 36V, 7.5 Ah Lithium-Ion battery, shared with the Tornado Strike Cordless Upright and Tornado Tempest Cordless Carpet Sweeper Vac, for up to 73 minutes of runtime per charge.
