Abstract
A fan unit in which a structure of a fan and a driving source thereof is improved to realize stable and high-efficient fan driving, thereby obtaining a high suction force in a stick type electric cleaner. The fan unit installed in a stick type electric cleaner includes a first fan and a second fan disposed in a line on the same rotation axis and a driving motor configured to drive the first fan and the second fan. The second fan is configured to be rotated in a direction opposite of a direction in which the first fan is rotated.
