SJE Corporation, Ltd. (also known as "SJE Corp") was established in 1991 in Busan, Korea. The company first focused on introducing European commercial and industrial high pressure washers to the Korean market. Within years, SJE Corp became the # 1 household reseller name in the high pressure washer industry in Korea.

In the year 2002, the company started targeting the steam cleaner market in Korea. The demand for steam cleaning equipments was steadily increasing as people needed a new way to clean carpet, upholsteries, and others because of westernized lifestyle.

With repeated sales increase, the company sought to provide users something similar to a domestic steam cleaner, but an industrial version. It had to be much more powerful and durable than ones on the market. After years of research and trials, SJE Corp introduced Optima Steamer Series to the Korean market in 2004.

We developed a steam cleaning machine, “Optima Steamer”, with our expertise and technology gained from many years of manufacturing cleaning equipments since 1991. Optima Steamers’ user-friendly applications, water-saving design, and superb quality made it possible for our customers from over 70 countries around the world to enjoy and benefit from steam wash and cleaning. We commit ourselves to continuously research and develop advance steam cleaning equipments to fulfill various customers’ needs around the world for many years to come.

We, as a “green” manufacturer, take pride in producing high-quality products, No.1 customer satisfaction and our commitment to preserve the environment.

We believe that our products will benefit your business and the environment.
