With the development of sensor technology, GPRS and other key technologies in many fields, cleaning robots have gradually been able to realize the automatic cleaning of the family and public health. Intelligent cleaning robots free people from heavy manual labor, greatly reduce labor costs, and improve work efficiency. At present, the intelligent cleaning robot on the market is mainly used in the household cleaning. The main functions completed by the cleaning robot: can automatically enter the room, can automatically clean and vacuum, or can clean the designated location under remote and manual control.Toilet hygiene is often the key to maintaining cleanliness. However, due to the humidity of the toilet environment and the complexity of the terrain which are relatively bad for robots, cleaning robots are rarely seen in toilet hygiene. In toilet hygiene, closestool cleaning is particularly important. This design will aim at the cleaning of the closestool. It uses planetary gears, guide rails and other mechanisms and at the same time combined by the MCU and its control of the color sensor, pressure sensor composed of the control system to realize automatic closestool cleaning.
