It's quite a new invention really for the domestic market!
Steam washing machines
are really quite normal washing machines but with an extra type of wash program.
One which uses steam and one which can use steam quickly to refresh items of
clothing in about 20 minutes. The LG model has a massive 9kg load capacity too
which means you'll do less washes, and as each load uses less water than that
on a standard washing machine you'll be saving energy and water too!
