Just 2 cleaning modes Clean and Gum Care, but that's all one needs to clean one's teeth. The Clean & Gum Care mode is EXACTLY the same as found in the expensive Philips Sonicare toothbrushes and it cleans in EXACTLY the same way as them. If all one wishes is to cleans one's teeth then this is it! Gave it 4 stars because the manual does not show how to change the 2 power intensities that this Protective Clean 4500 brush has.
