When it comes to deep-down cleaning, not all washer dryers are up to the job. So it's good to know that Hygiene Steam on your Samsung washer dryer banishes the things you can see & those you can't – bacteria, pollen, dust mites & more. The steam is released upwards to make sure every last item gets a deep & even clean. The results? 99.9% of bacteria are obliterated & allergens inactivated*. No pre-soaking, no hassle, no worries.
