Clean Is Happy. It's the campaign for TOTO's washlet toilet seat. TOTO is pushing the washlet as something really remarkable: it warms, auto opens, cleanses, and dries. We have zero experience with the washlet, which is an optional add-on for most TOTO toilets. We hesitate because added features like this that require your toilet seat to be plugged in generally amount to added complication. We prefer to keep it simple. Any experienced users out there with any wisdom to share?
