Question 1

Do i use all 3 brushes at the same brushing time?

Accepted Answer

Not necessarily, although the settings can be changed. When you attach one of the smart brush head, it will choose the optimum settings for your brush head type automatically for optimum cleaning. Clean is a 2-minute mode, White+ is a 2-minute 40-seconds mode, Gum Health is a 3-minute 20-seconds mode, Tongue Care is a 20-second mode, DeepClean+ mode length depends on whether or not the handle is connected to the app. In connected mode DeepClean+ runs for two minutes and provides BrushPacer feedback every 20 seconds. In non-connected mode DeepClean+ runs for three minutes and provides BrushPacer feedback every 30 seconds.

Question 4

Are the batteries replaceable?  How long do they last?

Accepted Answer

I’ve have a sonicare toothbrush that’s going on 10 years old now, best battery life I’ve ever had on any device. It’s still just as good today as the day I bought it. 1 charge lasts for at least a week. I’ve always been impressed with their batteries. I just took a spare toothbrush that’s been sitting in the sink cabinet for 4 years… it’s still holding a charge, I was blown away. Anyway, 10 years and going, I’d say I could easily get another 5 - 10 years but I’m obviously looking at newer models as some of the new features are attractive. You can’t go wrong with a Sonicare!
