1. A robot cleaner, comprising:
a driving part configured to drive and steer the robot cleaner in a progress direction;
a suctioning part;
a gas sensor disposed inside of the robot cleaner and configured to sense drawn-in air, wherein the gas sensor is disposed ahead of the suctioning part along the progress direction when the robot cleaner is moving in the progress direction and sensing the drawn-in air; and
a processor configured to identify contaminants based on a sensing value of the gas sensor, and control the driving part to change the progress direction to a second progress direction leading away from the identified contaminants.
