A robot vacuum cleaner and a controlling method thereof are provided. The robot vacuum cleaner includes a driver configured to move the robot vacuum cleaner; a memory storing information about a charging station of the robot vacuum cleaner; and a processor configured to: based on entering a return mode for returning to the charging station, control the driver to move the robot vacuum cleaner to the charging station based on the information about the charging station stored in the memory; perform a dust removal operation based on a distance between the robot vacuum cleaner and the charging station being less than or equal to a critical distance; and control the driver to move the robot vacuum cleaner such that the robot vacuum cleaner is in contact with the charging station after the dust removal operation.
