Many juicers are one speed machines for simpler use and because several speeds are not really needed for the task of juicing.
However, if your juicer does have multiple speeds, it isgenerallyaruleto use the lower speeds for softer fruits andthe higher speeds for harder ones.
The Braun models J700, J500 and J300 juicers have two speeds, and the SJ3000 has one speed.
