How does the Zamboni ice resurfacing machine work?

The basic process involves the machine’s sharp blade, which shaves a thin layer of ice as screw conveyors (augers) rotate above the blade to remove the shavings. The shavings are collected in a large bin, known as the snow tank. Meanwhile, jets of water clean the ice by flushing dirt and debris from the remaining grooves in the ice into a vacuum hose. Finally, a towel spreads the ice-making water (usually warm water), which sprays out of holes at the back of the machine, leaving behind a smooth sheet of ice.
