What makes open-on-the-side washers more energy efficient than washers that open on the top?

washer as in, a clothes washer (washer and dryer).What makes open-on-the-side washers more energy efficient than washers that open on the top?
They use less hot water. A top-loading washer has to fill almost up to the top to get all the clothes wet. A front-loader only needs a little water in the bottom, and all the clothes will tumble through it as the drum rotates.What makes open-on-the-side washers more energy efficient than washers that open on the top?
Yes on the less water to wash the clothes. And the centrifugal force of the spin gets the clothes much cleaner, using less water, less electricity. So all around it saves energy and natural resources. Plus they are easier on the back, almost no bending.
They use less water and it takes less kinetic energy (start the movement energy) to roll the drum around than to wiggle the agitator (thing in the middle of a top loading machine). It is called a front loader, by the way!
Yes to what others have said, but with one caveat - front loaders do not accept nearly as large a load as top loaders, and they take a lot longer to finish a load of laundry.
It`s not because how they open. One uses a lot more water than the other. And more power to spin more water out so there is Less dry time.
