Mini washers and dryers usually have a capacity between 1 and 2 cubic feet, and they typically are less than 36 inches tall, allowing for placement under kitchen counters, as of 2015. These appliances usually are about 24 inches wide and deep, although exact dimensions vary by model.
The mini appliances, also known as portable washers and dryers, are available individually or as combination washer-dryer units. The amount of material that fits in each unit varies by model, and a 2-cubic-foot device washes about 15 pounds of clothing. Some mini dryers are designed to operate without the need for external venting, which allows owners to place the units in any space.
