The BB-800 includes Bio Bidet’s patented, 3 in 1 nozzle that performs a front wash, rear wash and powerful turbo wash. Alternatively, the A7 comes with a 2 in 1 stainless steel nozzle that only offers basic front and rear washes. Additionally, the nozzles on both of these seat models provide a wide spray, an oscillating wash, and a soothing pulse wash.
