Are you considering the purchase of an all-in-one washer/dryer? Unlike an upright, connected washer/dryer system, an all-in-one washer/dryer unit is one combined unit that both washes and dries your clothing. Usually, the purchase of an all-in-one washer/dryer is less expensive and the machine itself is more compact, but there are other issues that may arise.
The Good: Small, Affordable, and Easy to Maintain
An all-in-one washer/dryer is often used in apartments where space is at a premium. However, it should be noted that stacked washer and dryer combos can usually take up the same amount of floor space. All-in-one units are less expensive than having to purchase a washer and a dryer separately and they are easier to maintain because there is only one unit to repair when it breaks down.
Many find that this type of unit is also easier to use, because they don't need to switch their laundry from one appliance to another. Instead, they just turn on the complete cycle and the machine washes and dries the laundry on its own. Since the cycle often takes a while, people can put their laundry in before they go to sleep and wake up to clean clothes.
The Bad: Inefficient and Slow
The small size of a washer/dryer unit means that it can't take in big loads, so there can be some problems for those who have a lot of laundry to do. In general, a combo washer/dryer cannot dry as quickly as a standalone dryer. The entire process of washing and drying will thus take significantly longer than it would ordinarily. Combo washer/dryer units also often have issues with a moldy or mildew scent, as they rarely dry entirely within. This can be countered by leaving the machine open to air out between washes.
The largest problem that most people encounter with a washer/dryer unit is that it often doesn't dry the clothes completely, due to the fact that the heating system in it is not as effective as a standalone heater. Many people find that they need to hang their clothes out for at least half an hour or so to dry them more thoroughly. The clothes will not come out wet, but instead just slightly damp.
Overall, a separate washer and dryer is usually more effective, but an all-in-one washer/dryer is smaller, simpler and cheaper. It all depends on how much laundry you need to do and how much space and money you have available.
