With a focus on simple cleaning, this toilet additionally uses foam for rinsing. A foam layer about 1 cm thick pours into the basin and floats on the water surface. During urinating, it ensures less spraying and a reduced noise level. The basin is formed in one pour; the hydrophilic surface of the ceramic is designed to cope with continuous water contact, thus facilitating easy cleaning. Some additional features help against invisible dirt such as bacteria forming mould and odour.
