The WORX 40V quiet boost, equipped with a high-efficiency brushless motor, delivers 28 cc gas-like power—effortlessly blasting through thick layers of wet, heavy leaves. With up to 780 CFM of air volume and 190 MPH of airspeed, it tackles heavy debris like damp leaves, compacted grass and small rocks with ease. It provides up to one hour of runtime with two 4.0 Ah PowerShare Pro batteries—allowing you to finish medium to large yard tasks on a single charge. This blower operates at noise level of only 57 dB while delivering powerful performance. With the battery positioned behind the handle for better balance—combined with low recoil and a lightweight design—this tool reduces fatigue during long cleanup sessions. Easily control the airspeed with the variable speed trigger to match the task or lock it into place with cruise control. When you need extra power for tough conditions, just press the Turbo button for an instant boost. New to PowerShare?
