Haan SI-35 Floor Sanitizer and Vapor Steamer:
Material: Plastic and aluminum
It seems like such a simple idea: Invent a mop that uses heat, rather than chemicals, to sanitize the floor. But South Korean entrepreneur and mother Romi Haan has developed that concept into a $100 million business in just over a decade. Her company’s line of products—which now also includes vacuums and garment devices—all use steam to neutralize germs and rid surfaces of odor and dirt. Haan’s tools clean faster and more effectively than traditional methods: No wonder 3 out of 4 Korean households own a product by the company.
