6. A robot cleaning system comprising:
a robot cleaner that cleans a cleaning surface while autonomously driving;
an external control device that displays a control screen for controlling the robot cleaner and receives a reference distance for detecting a surrounding environment of the cleaning surface, the reference distance being set by a user input through the control screen; and
a sensor unit that detects a height from the cleaning surface to a lower side of the robot cleaner as distance data,
wherein the robot cleaner is controlled based on the reference distance set by the user input through the external control device and the distance data detected the sensor unit.
