Abstract: A robot cleaner is disclosed. The robot cleaner includes an infrared sensor including a light emitting device configured to output an infrared ray to a floor and a light receiving device configured to receive the infrared ray reflected from the floor and convert the received infrared ray into an electric signal and output the electric signal; and a processor configured to determine an output voltage of the electrical signal if the electrical signal is received from the infrared sensor, control a travel direction of the robot cleaner based on the output voltage and a predetermined first threshold voltage, and control a suction mode of the robot cleaner based on the output voltage and a predetermined second threshold voltage, wherein the second threshold voltage is higher than the first threshold voltage.
