This is now my 5th Sonicare. I had all models. I know of no toothbrush cleans better. One must however be aware that the units are designed for a service life of about 2 years. After that, they go always broken. The way the defect deviates from model to model. My last was for example someday itself on and off and read no longer be controlled.
None of my product is ever become so clear that it deliberately breaks. Unfortunately, the strategy of Philips goes on, I order again and again a new Sonicare.
