Most people have a washing machine and have experienced a break-down in that machine at some time or another. Very often it is not until something breaks down that we really appreciate the convenience the machine affords us. Having to wash clothes by hand like grandmother did will soon send you scurrying for the phone and the spare parts manufacturer for your machine.
Those that want to consider the environmental impact can go "green" with a miniature hand-operated version. They are inexpensive and use very little soap and water, and no electricity. If you want the absolute king of the hill when it comes to engineering and performance, treat yourself a Miele washing machine.
