This smart toilet features foaming technology; a dense foam barrier layer is formed on the water seal layer of the toilet before using, to effectively prevent splashing, deodorizing and antifouling. When the excrement falls in, the foam firmly locks the water layer to prevent splashing and the odor. The dense foam adheres to the self-cleaning glaze of toilet, so dirt finds it hard to accumulate. In terms of optics, this is an elegant and slimline design. A cylindrical control axis runs through the pure surface. The “auto-cleaning” knob is integrated within the axis. Press to start and stop, and rotate to adjust the parameters.
