Abstract: A robot cleaner includes a main body, and a wheel unit including a wheel configured to movably support the main body. The wheel unit is installed in a suspension unit and configured to be movable upward or downward. The suspension unit is configured to absorb impact when the wheel unit moves upward or downward, and is installed in a lifting unit coupled to the main body. The suspension unit is configured to be raised or lowered relative to the lifting unit. The lifting unit includes a lifting drive motor including a rotatable shaft disposed in parallel with a direction in which the suspension unit is configured to be raised or lowered, and a transmission unit configured to transmit a rotation force of the lifting drive motor to the suspension unit.
