Enhanced flush Roca’s Rimless technology features a new water distributor that propels a stronger flush, spreading it homogeneously throughout the entire bowl. Larger clean area The new design of the bowl includes a slight uppedge tat allows ater to flow upwards, cleaning the entire surface, above the standards required by the European Union. Splash-free Both the design of the bowl and the water propulsion system have been conceived to achieve a maximum efficiency flush, preventing water from splashing outside the bowl.
