Vibrations in a washing machine contribute to wear and reduce the life span. We have made our machines extra sturdy by building on four powerful spring legs rather than two shock-absorber legs. Particularly nice if you live in a wooden house or apartment building, where vibrating washing machines can be a real disturbance. We also build our machines on a galvanised steel base rather than a plastic base, just like a professional washer. Needless to say, this also increases the life span. As far as we know this is unique to ASKO.
