The 3-in-1 S1 can automatically wash, dry, and sterilize underwear. Instead of scrubbing clothes with hands, the S1 with the industry-first MBS (Micro Bubble Suspension) washing technology can release numerous nano-bubbles to thoroughly remove the stains. It will then dry clothes at a low-temperature and negative-pressure condition, while preventing fabric damage. Meanwhile, over 99.9% of bacteria can be killed through all-round sterilization. Better still, its "smart care" function will be set off if clothes are left in it for a long time, performing cyclic venting to keep odour at bay.
