Balanced spinning
It's crazy that some machines have this issue, trying to spin a load.
I can honestly say that the best machine that I have used is undoubtedly my Zanussi IZ16. It tumbles clockwise and anti-clockwise several times at varying speeds and duration, before it even imagines going into distribute speed. Then it does a very short, slow spin, to get most of the water out. After that it does its balancing act again, then proceeds properly into the stepped spin profile. It seems to be a well thought-out sequence.
Some of the worst 'movers and shakers' that I have seen are the machines that go from the final rinse into distribute speed, then spin, without properly tumbling back and forth. My Mum's Bosch seems to have this issue.
