Miele Washing Machines are Designed for Long Lasting Performance Miele washing machines are designed for long-lasting performance. So you can get the perfect clean for your favourite clothes, year after year. 30% of our development time goes into testing. To guarantee outstanding results, for years to come. A washing machine should be seen, not heard. That’s why we test every appliance not only for a long service life and a hygienic, sustainable performance but also for very low noise levels.
