6 Tested for the equivalent of 20 years' use Miele carries out intensive endurance tests during the development phase in order to meet the highest quality standards. In these tests the appliances (e.g. washing machines) are expected to wash for 10,000 hours. This involves running a mix of approximately 5,000 wash programs. This corresponds to approx. 5 programs per week with an average cycle time of two hours – over 20 years. Highest levels of product quality, perfect and outstanding results – and extremely efficient at the same time. The highest demands on production and the materials used underline Miele's brand promise: "immer besser" (forever better).
