The HS-9000 is a cordless wet cleaner that makes thoroughly cleaning floors in private households easy. The LED light on the lower part of the device clearly illuminates the floor in front of the cleaner while the LED light on the upper part indicates the battery level in three different colours. The design pays special attention to the body of the device. Its curved contours pick up Korean handcraft tradition and are inspired by the silhouette of Goryeo celadon, a grey-blue-green glazed porcelain from a past era.
