The WORX Trivac 3-in-1 blower/mulcher/yard vacuum brings all three functions together in one compact, lightweight machine with a metal impeller: a great blower, a handy mulcher and a powerful Yard vacuum. As a blower, the Trivac produces an airspeed of up to 210 mph, strong enough for the toughest wet leaves and debris. While vacuuming, the high-impact-resistant impeller mulches leaves up to 1/10 of their original size. When in vacuum mode, the powerful motor in the Trivac generates 350 cu-ft of airflow per minute.
