:If you are talking about a machine like mother had in the 50's where you actually stored the wash water in a deepsink and the machine pumped it back in to reuse for the next load, you are too old to be doing your own laundry! Just kidding, but that's how long ago they stopped making those.
However, today's front loading machines are very low water users; and more important, they extract so much water in the high speed spin that you save an enormous amount of drying energy.

Home Depot has become the 2nd largest seller of appliances in the US. Good prices, too. Check them out.
