Due to EU and US regulations, latest models of washing machines are really eco-friendly and use much less water thant their previous models. The problem is, this has to be countered by increasing the time to run the programs in order to keep the washing results good. Regular 60 C degree cotton program can take anything from three hours up to four. Often these models have also 1 hour fast wash, but the results are far from good if your clothes are even slightly more dirtier than your regular one day worn shirt. Some times it would just be really convinient to load the machine half full of water, run the fast program and still get good washing results.
