When you only have a small amount of laundry to do, washing it in a big washing machine is a major waste of electricity, but washing it by hand is tiresome. While that might have been the original inspiration for this product, its applications actually go much further. As well as being handy for use in places without mains water or electricity, it is a cheap option for homes without a washing machine, which will also avoid pushing up the electricity bill. The highly interesting design encourages one to imagine a range of potential uses. For example, people would doubtless find its spin dryer capabilities helpful if this device was installed at beaches or campsites. It's easy to use, effective and eco-friendly.
