Well, I'm happy with our Siemens. Regular cycle takes 140 minutes and uses 14 liters or 67 minutes and 18 liters if I use the VarioSpeed option. While this is less water than most US dishwashers use, cleaning is superb. Even if there is water left in indentations of cups which have been placed in the corners of the upper rack - it's clear because the DW has a four-stage filtration.
Despite the lower water level the water pressure is very powerful. I remember throwing some screws in the cutlery basket (I always remove the handles of lids before loading them into the DW). Then I closed the cutlery basket's flip-down cover and added all the cutlery. At the end of the cycle all the screws were trapped in the filter - the water jet just shot them through the basket even though it was loaded with cutlery AND the cover was closed.
