The Trivac is the tool most buyers think of first when picturing an electric leaf vacuum, and the spec sheet explains why. It claims 350 CFM and 210 MPH, a balanced pairing that moves leaves into the tube without making it a high-pitched jet. Leaves are pulled through an impeller and shredded, so a full bag holds noticeably more than loose leaves would.
Compared with the DUMOS at 500 CFM, it claims less volume, but the figures look more conservative and the brand has a long record of parts support. The mulching impeller is a plastic wear part that can jam on wet or twiggy material, so clear it with the tool unplugged.
Empty the bag often, keep the intake clear and store it dry. It is the choice for a small to mid yard where you want leaves reduced for compost or lawn mulch. In year three, the parts that matter are the bag, the impeller and the cord, all of which are cheap and easy to source for this model, which is a real point in its favor. Storing it indoors on a hook keeps the plastic from becoming brittle in winter cold. Against a cordless machine, the trade is simple: you give up walking freedom and gain a tool that never needs a battery.
