Question about Philips Sonicare ProtectiveClean 5100

I don't know. Flicking through the Philips brochure would help.

I would recommend that you choose a different brand of toothbrush, for example Panasonic. As my Philips toothbrush didn't last very long, it was replaced under warranty and didn't last long either. I'm not insisting, just sharing my experience.
