I have the 9.0kg Simpson EZI sensor machine top loading. It is AWESOME!!!! Same as what nickle said. We only have tank water and this machine uses LESS water than my old 4.5kg Simpson did!! I had the 4.5kg simpson for 11 years and only replaced it 18 months ago because we outgrew it and I was sick of doing up to 4 loads of washing in a day for the 6 of us. The size is perfect for the 6 of us and I hope to get as long out of it as I did my little one. I think you should get one that is big enough to wash blankets etc because that was the only downfall of my small one - great machine but too small to wash blankets and sheets. I couldn't even fit a single bed sheet set in it at the one time to wash it. So 8kg may seem huge, but once you are washing extra linen, you will be glad you went for a bigger one.
