Front-loaders use less water than top-loaders but typically have longer wash cycles—some take 100 minutes or more. That's not the end of the world, but it may be the beginning of laundry pile-up. Since front-loaders use less water, the detergent is more concentrated and the machine's tumbling action can also help boost cleaning. Manufacturers recommend using HE detergent—that's high efficiency—for front-loaders and HE top-loaders. Regular detergents are too sudsy for these machines.
The best front-loaders clean better and use even less water than the best HE top-loaders. Front-loaders spin faster than HE top-loaders so more water is typically extracted, reducing drying time but front-loaders generally have longer wash cycles. HE top-loaders don't have a center agitator and use a variety of methods to lift and tumble laundry. They're high-efficiency because they use less water and spin faster than conventional top-loaders, also cutting dryer time...Now you know!
