Abstract
The robot according to the present invention sequentially performs a collecting operation in which dust and particles on the floor are collected, and a cleaning or waxing operation. The cleaning robot includes a moving unit including driving wheels or crawlers, a collecting unit for suctioning dust from the floor, and a wiping unit for wiping the floor with a detergent, disinfectant, wax, etc. The collecting unit is positioned on the front of the cleaning robot with respect to the moving direction while the wiping unit is positioned on the back of the cleaning robot. Thus, the robot prevents secondary contamination of the floor and slippage or failure of the moving means caused by soiling of the moving means. The cleaning unit and the wiping unit include sensors which sense an obstacle and determine whether the obstacle is one which can be moved over, such as a cord, or whether the obstacle is one which must be avoided, such as a wall.
