The 7kg- as the 8kg variant have the best energy efficiency class A +++ and 1400 rpm, as well as the control over a combination of rotary knob (wash cycle), and buttons for options such as temperature (20, 30, 40, 60, 95 degrees) spin speed (400, 800, 1200, 1400) and the like. Likewise, remaining time display and a time delay to allow starting the washing program during an absence at a particular time (with reference to the desired end time, very practical).
The washing programs are identical: the usual suspects (cotton, wool, easy to maintain, hand wash,) and a few special features: dark wash, outdoor clothing, jeans. An additional function enables a quick wash in 15 to 60 minutes, which can be combined with different washing programs. A weakness of both models: The energy-saving washing is a program on the knob, no additional option is therefore not be combined with other programs. At our last Siemens machine on the other hand, each program made by two keys instead of the normal process also particularly fast or select particularly economical.
Both machines feature automatic reset on the weighted amount of laundry and a need for half-full drum less time and water. But the abundance of additional opportunities for both is almost too much of a good thing: When should I use the patch program and when more advanced options such as intensive care, soaking or pre-wash now? The equipment moves just as a certain overkill to which probably will go back sometime again in favor of things that you really need.
A specialty in all recent Samsung models, so even with WF70 and WF80 is the active foam technology that will provide at lower temperatures for clean laundry. I confess that I for normal laundering continue the usual wash temperatures of 30 to 60 degrees, I use did this simply a better (cleaner) than feeling cold wash. At the (identical) noise of the machines is nothing to complain about.
When I came in with minor reservations stronger machine at four and a half star and have rounded up overlooking the good price-performance ratio to five, it may be here according to four star. In the original price, the two washing machines are quite farther apart, but at the current Amazon price they are so close together moved that the acquisition of weaker variant still makes little sense.
