A floor processing device has at least one electrical consumer, a battery for supplying power to the electrical consumer, and a control device for controlling the floor processing device. In order to avoid recharging the battery during an operating activity, the control device determines the anticipated energy required by one or more consumers to perform and fully complete a predefined operating activity, compares the anticipated energy required with an amount of energy stored in the battery, and if the stored amount of energy is less than the energy required, reduces the energy required by adjusting one or several operating parameters for the operating activity, in order to successfully execute the operating activity.
