Extremely loud when brushing, at all three setting

Why is it so loud? Has been extremely loud since day 1. Thought it was by design. If so, poorly designed.

Hello!
We apologize for the inconvenience you're experiencing with your Sonicare 9000 Series toothbrush. Though some sound is expected due to the sonic vibrations it uses for effective cleaning, it shouldn't be overly loud. Please ensure the brush head is properly attached and check for any signs of damage to either the head or handle. If you've verified these aspects and the noise is still a concern,please reach out to us.
We are available on social media, Facebook/Instagram (@Philips) or X (@PhilipsCare). If you don't use social media, you can also get in touch via our contact page.
Best regards,
Philips Consumer Care

[This review was collected as part of a promotion.] Excellent cleaning. Feels like I just left the Hygenist. Sorry I did not buy one years ago.

[This review was collected as part of a promotion.] This toothbrush is amazing. I especially like the deep clean and the whitening modes. I was skeptical but they really work. I’m surprised by the power this bush has. I couldn’t be more pleased!

Clens well but mechanical design needs improvement

We have had several Sonicare devices and all have suffered from the same design defect. After about a year and a half of use, the buttons require more and more physical force to press until the handle is no longer usable without super-human strength. Philips was good about replacing our last handle but eventually the replacement failed as well in the same manner. Perhaps the button seals cannot survive the saliva over time. Our last charger failed when water spilled on the counter and touched the charger (our fault). I would recommend placing your charger on a trivet or ceramic coaster so that does not happen to your product, but the charger should be better sealed by Philips as well.

[This review was collected as part of a promotion.] I love how convenient this product is . How it keeps you honest with the synch data forcing you to brush twice a day. Even if you feel lazy you don’t want a bad review of data for your regimen

Big improvement over my former electric toothbrush

[This review was collected as part of a promotion.] I chose this one because of all the unique features: for making teeth whiter, deep clean, and one I like best, gum health, besides having a regular clean feature. I received a great report from my dentist during this last visit, and am sure this product was a contributor.

[This review was collected as part of a promotion.] I have been using Sonicare toothbrushes since 2001 and have been told by both my dentist and hygienist that my oral health improved dramatically. Since then I have purchased 3 more, including a Diamond Clean, the 9000 is my latest purchase. It has more features than any of the others and I believe that it does an even better job of cleaning my teeth. I recommend this Sonicare without hesitation.
