i believe it depend what you juicy, in my case is high fibre vege such parsley, celery. it depend how cleanness level you want, my case i want remove every tiny hole.

traditional juicer will have similar problem in cleaning on strainer, assembly, etc. but you talk about blender, by the design of blender is way simple there are no strainer, etc basically just blade and body. blender will not juicy for leaf vege... i am lazy to elaborate more.... continue what you like to blend.
