Because of bearing damage a new World Cup had to be purchased. Reliability and fuel economy were key reasons for this World Cup. The brushless motor with a guarantee of 10 years and the robust construction in favor of this World Cup. The operation is so quiet that I looked again at the first washing process if hurls übe3rhaupt. The washing result is unparalleled. The laundry is absolutely clean and in spite of only 1400 revolutions / min. relatively dry. I can only recommend it, by analogy, the same design of Siemens WM. Who does not want to dig deep into their pockets can also be a model of the same series set, where a normal engine always underlies a certain brush wear and so the additional price for about twice brush change should be caught again.
