This application provides a method for controlling a robot cleaner, a robot cleaner, and a storage medium. The method for controlling the robot cleaner includes the steps of: acquiring a weight of the water tank, comparing the weight of the water tank with a setting value to acquire a comparison result, determining a remaining usable time of the robot cleaner according to the comparison result, and controlling the robot cleaner according to the remaining usable time. Since the weight of the water tank is not easily interfered by other factors, the acquiring of weight has a high accuracy, thereby the remaining usable time determined according to the weight of the water tank has a high accuracy, and then the robot cleaner is controlled according to the remaining usable time with higher accuracy. The control accuracy of the robot cleaner thus can be improved.
