Nozzles that stream water are distributed by the top portion.
The two lid pieces are held together by magnetic and on the top lid there will be a button to press for you to hold the amount of water you would like to use to clean.
The outlet that attached to the base of the toilet is S shaped so that a water seal does not allow the sewer odor to be smelled.
The red and green tubes just stand out for clean water in and dirty water out but will be the color of the toilet to be less noticable.
The lid has to be closed for the nozzles to spray so that water does not leak.
