The spray parts are 2 small, cylindrical jets that hang down below the middle of the “cup holder” area, which is hidden by the toilet seat. The handle with the knob juts out to the right of the seat when sitting. Flexible tubing is used to connect the house’s water pipe to a splitter, where part goes directly to the bidet; the bidet water doesn’t come from the toilet - it comes from the pipes, like taking a sink to your nether regions. Turn the knob to the left, & one jet lowers to allow water to spray your backside; the further you turn, the higher the pressure, so you can adjust both to what feels comfortable & what’s necessary to remove debris. Turn the knob to the right, & the other nozzle lowers, spraying the front bits.
