Is this the world's smartest toilet?
A warm toilet seat isn’t most people’s idea of heaven, typically indicating a previous occupant only recently departed. And turning to your side to find no toilet paper, only smooth walls and a remote control, may seem positively hellish. However, this remote control has washing and drying options. Press it, and a robot arm slides out underneath you, offering a range of water jet speeds and angles, followed by a hot air finale. When you stand up, the toilet closes its lid, flushes itself, and then self-cleans using UV-light.
