Since the 1970s, we at Mariner 3S have played a key role in the development of pool floor cleaners. Initially, manual devices dominated, followed by the first automated systems in the 1980s. With the advances of the 1990s, we further refined the technology with improved sensors and controls. Since the 2000s, we have been integrating smart technologies and networking functions into our products. Our focus is on close cooperation with our customers and the continuous transfer of knowledge in order to always offer innovative and high-performance cleaning robots.
