There are 3 modes: Cleaning, Whitening, Gums. Each mode has different vibration patterns and length of time. So not exactly "speed". But they do a very good job of cleaning.

I would not say a 'selection of speeds' more like a selection for the type of cleaning you want for differing areas of the mouth.
