Both a front loading washing machine and a top loading washing machine wash the clothes just as good.
But I find that the front loading washing machine is much better and uses less water and energy than the top loading washing machine does.
The front loading washing machine is also easier to keep clean and has more room for things such as comforters and washes things such as Teddy Bears much better unlike the top loading washing machines.
Some top loading washing machines have the agitator and some others do not have the agitator for the top loading washing machines with the agitator some clothes and sheets can get tangled up and if you try to wash a teddy bear in the washing machine with an agitator the teddy bear can get torn up.
If you want to save energy then I would recommend the front loading washing machines even though they are a bit more expensive than the top loaders.
