Vacuum cleaner springs are extremely small, and are used as energy storage devices in traditional household vacuum cleaners. They are produced using a reverse winding process to ensure the spring offers enough force to pull electric wires. We offer different color choices, including black, gold, and silver, with the strength customizable simply by changing the heat treatment process to ensure the stretching and retraction of the electric wires is smooth. Vacuum cleaner springs are designed to specifically match different cleaner structures.
