The Biffy bidet waits nearly out of sight under the seat rim. When you're ready for a clean bottom push the handle back and it swings out under the "target" zone and turns on automatically. Aim the row of cleansing jets by moving the handle. Release the handle and the Biffy self cleans its spray nozzle, shuts off, and goes back into hiding. Unlike a standard bidet, you’re in complete control of the position, pattern, and pressure with a simple push of your thumb. Biffy gets you really clean, really fast. The Biffy spray nozzle retracts inside of its protective housing when not in use. When you use it, the first thing it does is rinse itself with a turbo spray of fresh water. Then it comes out of its housing and cleans you. When you're finished using the Biffy, it retracts and rinses itself off again. This automatic self-cleaning feature gives you the assurance that the "business end" of the Biffy is always freshly cleansed when you want to use it.
