you plug it in to use it, click the button and it spins. the area you pour is separated with a silicone bowl thing (the pink part) and has groves to make cleaning brushes easier. pour water and soap in it, and put a dirty brush or beauty blender in it and hold it down for a few minutes, and itll be good as new!! really good actually it surprised me a lot. im sorry i dont have before and after photos but believe me this works well! i also imagine that it would be nice for paint brushes.
