Vision is an elegantly designed toilet with multi-stage water sterilisation. Incoming tap water first passes through the anti-scale filter to remove impurities and then through the UV and silver ion modules inside the electronic cover. Together, the cleaning modules achieve a hygiene level of up to 99 per cent when disinfecting the rinse water and the ceramic inner wall. This convinced the jury just as much as the emphatically straight-lined, mirror-glass design of the smart toilet.
