That's how long it will take before you actually save money. Depending on which models you're comparing, you'll probably find that it will take between 3 and 7 years for the operating savings to recover the extra purchase expense. In fairness to top-loaders we should point out the most of the newer units are more efficient than older models were. There are also some drawbacks to front-loaders. Soils are more likely to redeposit on other clothing in the load.
Dyes can bleed and detergents have a harder time dissolving because there's less water.
There's also more than saving money to consider with front-loaders. We mentioned the fact that your clothes should look better and last longer. But there's also the environmental concerns. In many parts of the world fresh water is scarce and it's a shame to use more than is necessary no matter where you live. Don't forget to consider some other ways to reduce the costs of doing laundry.
