         5 . The cleaning robot as claimed in  claim 1 , wherein the notice information is an image or a voice. 
     
     
         6 . The cleaning robot as claimed in  claim 1 , wherein the control module controls at least one of a rotational direction and a rotational speed of the rollers according to the detection signal. 
     
     
         7 . The cleaning robot as claimed in  claim 1 , wherein the control module controls at least one of a suction of the suction aperture and an air flow rate of the dust collection box according to the detection signal. 
     
     
         8 . The cleaning robot as claimed in  claim 1 , wherein the control module controls a rotational speed of the cleaning brush according to the detection signal. 
     
     
         9 . The cleaning robot as claimed in  claim 1 , wherein the shock is generated by a base case and the movement module is disposed under the base case. 
     
     
         10 . The cleaning robot as claimed in  claim 1 , wherein the shock is generated from a piezoelectric film, which is disposed in an air-stream flow channel of the suction aperture. 
     
     
         11 . A control method for a cleaning robot, comprising:
 moving the robot;   detecting a shock to generate a detection signal; and   controlling an operation of the robot according to the detection signal.   
     
     
         12 . The control method as claimed in  claim 11 , wherein the step of detecting the shock is to utilize a gravity sensor to detect the shock. 
     
     
         13 . The control method as claimed in  claim 11 , wherein the step of detecting the shock is to detect the shock generated by a base case of the cleaning robot. 
     
     
         14 . The control method as claimed in  claim 11 , further comprising:
 disposing a piezoelectric film in an air-stream flow channel of a suction aperture of the cleaning robot.   
     
     
         15 . The control method as claimed in  claim 14 , wherein the step of detecting the shock is to detect a voltage of the piezoelectric film. 
     
     
         16 . The control method as claimed in  claim 11 , wherein the step of controlling the operation of the cleaning robot is to control a traveling route of the cleaning robot. 
     
     
         17 . The control method as claimed in  claim 11 , wherein the step of controlling the operation of the cleaning robot is to control at least one of a suction and an air flow rate of the cleaning robot. 
     
     
         18 . The control method as claimed in  claim 11 , wherein the step of controlling the operation of the cleaning robot is to control at least one of a display light, a display panel and a voice generator of the cleaning robot to display a dynamic image or a static image.
