The "onyx" and "platinum" models are not a specific type of Samsung electric front load washers, but rather two of the different color choices that some of the models are available in as of 2015. Other color choices for Samsung front load washers include white, blue and merlot.
Samsung produces 10 different models of front load washing machines, which range in capacity from 3.9 to 5.6-cubic feet. The two largest models, WF9100 and WF9110, both have a 5.6-cubic feet capacity that Samsung claims these models are the world's largest washers, which can handle three times the laundry. In addition to being the largest, these two models are also the most expensive with a price tag of approximately $1,700.
Many of the front load Samsung washers have received the federal Energy Star certification, while a number of them also come with the SuperSpeed function that allows users to wash clothes in up to 40 percent less time. Some of the models also come with the company's trademark VRT technology to reduce vibration and noise. Many also include either the SelfClean+ or PureWash self-cleaning systems.
In addition to front load washers, Samsung also produces a variety of top load washers and dryers. These products are available in the same array of color choices.
