WindTunnel Technology uses computer designed air ducts to provide a powerful dual air stream to enhance dirt pick up capabilities. The WindTunnel design also reduces the scattering of debris, common to many ordinary canisters. The WindTunnel Bagless Power Nozzle Canister with Electronic finger-touch variable speed control, remote fingertip power on/off and remote fingertip brush roll on/off, picks up more dirt than any other canister...period!
