Automatic rinsing 

For consistent performance 
Mineral residue left behind by the evaporation process must be regularly removed by rinsing the steam generator to ensure consistent appliance performance. The steam ironing system calculates rinse intervals automatically based on the volume of water evaporated. The rinsing process will then commence automatically immediately after the ironing system is switched on. All you need to do is empty the residual water container.
