There are certain aspects of juicing that can slow down or speed up the cleaning process. For a start, the speed at which you juice will affect how much mess is produced.
A slow juicer makes juice using slow masticating technology, which naturally means produce has more time to linger inside the juice bowl - and stick to the sides. Centrifugal juicers use high-speed centrifugal force, which means it's less likely for produce to get stuck where it shouldn't be. Keep in mind, though, that they also produce a wetter pulp, which doesn't exactly promote easy cleaning.
How much juice you plan to make may also affect your cleaning process. If you make a lot of juice, and you're running more produce through the machine, you'll have a higher volume of pulp to deal with when it comes to cleaning.
