- the relevant parameters such as water hardness and concentration of cleaning agent are in particular by the controller 82 at
- the control device 82 can by evaluating the data of
- Impedance sensor device 86 and set corresponding operating parameters of the floor cleaning machine 10 optimized.
- a display device may be arranged, on which measurement data of the impedance sensor device 86 can be read. They can be read directly or it can be displayed accordingly prepared data such as a cleaning agent concentration in the discharged to the floor 26 to be cleaned liquid. For example, if the type of cleaning agent is determined, then it can also be displayed on the display device. It can also be displayed, for example, the determined degree of hardness of the fresh water. For example, even if such a determination is provided, the type of contamination can be displayed or a concentration of dirt in the extracted dirt-laden liquid.
