Vacuum cleaner and method of displaying state thereof
First Claim
1. A vacuum cleaner comprising:
- a suction part that is configured to receive dust; and
a cleaner body that is coupled to the suction part, that is configured to collect dust from the suction part based on suction force, and that includes;
a main body,a suction motor that is configured to generate suction force,a wheel that is coupled to a first surface of the main body and that is configured to rotate about an axis to move the main body,a driving unit that is configured to generate driving force to move the wheel,a display unit that is coupled to the wheel and that is configured to display operation state information of the vacuum cleaner, anda controller that is configured to control the driving unit and the display unit.

20. A method of displaying operation state information of a vacuum cleaner that includes a main body, a wheel that is coupled to a first surface of the main body and that is configured to rotate to move the main body, a driving unit that is configured to generate driving force to move the wheel, a display unit that is coupled to the wheel and that is configured to display operation state information of the vacuum cleaner, a controller that is configured to control the driving unit and the display unit, and a sensor that is configured to sense movement of the main body, the method comprising:
-
initiating, by the controller, an operation of the sensor; sensing, by the sensor, movement of the main body; controlling, by the controller, the driving unit to move the wheel to move the main body; and controlling, by the controller, the display unit to display a rotation direction of the wheel.
