Strictly speaking, all vacuum cleaners use magnets. Magnets are crucial to the electric motors that create the cleaner's suction. Some vacuum cleaners, however, are adapted with a magnetic device that removes metallic objects before they are sucked up.

Vacuum cleaners use powerful Neodymium magnets in their motors to give high suction from the smallest and lightest motors.
