UNLEASHED. We removed the cord but kept everything else. Finally, a full-size, cordless, cyclonic vacuum that can clean your whole home*. Two LithiumLife batteries provide an average of 50 minutes of fade-free power to clean both carpets and hard floors. That’s enough to clean a 2,500 square foot home with no loss of suction** and without recharging. WindTunnel 3 technology allows you to clean deep with three nozzle channels of powerful suction to capture dirt — other vacuums rely on one. The Air Cordless vacuum contains all the technology you’d expect to find in a Hoover upright, minus the cord. A simple change that changes everything. *With two LithiumLife batteries, get up to 2,500 square feet of carpet, hard-floor and above floor cleaning with removable wand. **Per IEC60312-1 1st Edition, Clause 5.9.
