Let's be honest: it's hard to get excited about laundry machines. Even when they have neat party tricks like Amazon refills and smartphone apps, it really boils down to one question: does it clean your clothes properly? Samsung thinks it can do enough to make you sit up and take notice, though. It's unveiling a FlexWash + FlexDry laundry machine combo that includes both dual washers (which we've seen before) and dual dryers. You can completely clean your delicates without having to disrupt your main load, for instance, or run up to four loads at once if it's particularly busy.
