A two-stage cordless snow blower is a snow removal machine that operates using an electric motor, with a two-step process for clearing snow. First, it scoops and breaks down the snow with an auger, and then it expels the snow at a greater distance using an impeller. These machines are efficient at handling heavy or deep snow, are relatively lightweight and easy to maneuver, and require less maintenance than gas-powered snow blowers. They're also the most suitable type of snow blower for gravel driveways since their auger is elevated.
