Abstract
A robot cleaner having a fan brake device is provided, which includes a main cleaner body having an accommodating slot used to contain a dust box and a fan, and at least one brake device is disposed inside the accommodating slot. The brake device is disposed at a notch on the bottom of the dust box for the fan to be inserted into, and under the junction line between the notch and the bottom edge of the dust box. Therefore, when the dust box is taken off from the main cleaner body, the flexible element of the brake device can press a soft stopper upward and then the soft stopper presses against the bottom of the fan blade of the fan to stop the fan.
