[This review was collected as part of a promotion.] I have purchased a few Phillip Sonicare toothbrushes over the past. Recently, I purchased DiamondClean 9000 HX9911 in January 2026 and had trouble getting it to work until April 2026 at which point I contacted Phillips Sonicare and they exchanged my defective DiamondClean 9000 HX9911 with a new one which works!

This is a great product

philips.com

This is the only brush that makes my teeth look and feel clean. In addition, my teeth are much whiter since I started using it four months ago. My sister and brother-in-law got it for my birthday as they knew I had been searching for the perfect toothbrush. They both use one daily and love it too! Now I even travel with it as I was gone for a week traveling without it, and I could not get my teeth to feel clean. I couldn't wait to get home to my Philips DiamondClean Smart! Since then I have traveled with it twice, last thing to pack and first thing to unpack. It travels well in the case that comes with it! Thanks for this fine, dependable product.

Best toothbrush ever!

I have been using diamond clean for years and I credit my excellent oral care to it. I really don't use the coaching because I don't need to but what a great idea for those who do. This pink one matches my bathroom and makes me happy. My teeth just sparkle and contain zero plaque. Thank you Phillips for taking such good care of my teeth. This is the wisest investment one can make to ones general appearance and well being. Years ago I had dental assistants match crowns to the color of my teeth. I wish I would have requested whiter crowns. There is no better proof than that, PHILLIPS rocks.

pretty in pink

The toothbrush has a superb cleaning result. The battery doesn't last as long as my old cheaper electric toothbrush and the replacement heads are a little pricey. I guess if you want a really good cleaning, I have to pay for the OEM replacement heads

Crazy clean, just like the dentists office.

I've been pleased with the toothbrush and its many features. However, I am confused about when to replace the brush head. The very brief brochure describing the features only mentions that an icon will appear when it's time to replace the brush head. There's no mention of what the icon looks like. My brush head is getting worn but I haven't seen any icon other than the "Clean" light flashes when I finish brushing, but I don't know if that's the one telling me to change the brush head. Also the battery light goes on and off when it's time to charge, but again that isn't mentioned in the brochure, so I just figured it out intuitively.

Very good toothbrush but sketchy documentation

It's good don't get me wrong but I find the heads are very large so hard to reach the back of your mouth,
Considering the price I would expect a bit more from the toothbrush although it does clean very well once you get used to just how powerful the vibration is, it would be nice if there was a smaller possibly round or oval shaped head available (like my previous oral b) as that seemed a much more convenient size for harder to reach areas. The app is more of a gimmick that I used 2/3 times at the beginning but not much after a month or 2 and it doesn't always detect the correct position you are at, the area timer also doesn't really give enough time on each area to get all around the teeth,

Not perfect but a good toothbrush

This is my third Sonicare toothbrush. They have sure come a long way.
This has been a change for me with this toothbrush, it seems that I can't get a good control with it, due to it's smooth exterior surface of the handle, it slides in my hand and I have to keep readjusting. It is a quality product as always, I just don't like exterior finish.

I like most of the upgrade...

Save yourself the extra money, unless you really think that you need to hook your phone up to your toothbrush. Overpriced, overteched product. Have been a fan of Sonicare for over 20 years. but this is not necessary. I have never synced it with the app and never finish the extra long cycle.

An App for your Phone?

I like the way it cleans but I could have gotten a less expensive model that did that as well as this one. 

The battery lasts maybe a week before it needs to be charged. The charging case they sell does not work for this model and there are no convenient reasonably priced travel chargers for it.

I would not buy it again or recommend it to others.

Cleansing is good battery life is not no travel charger

The product is easy to use. It performs well, just like all of your other Toothbrushes. For me, just give me, a regular electric toothbrush. I don't need all the Bells,and Whistles. (Aka The Bluetooth Technology) Keep it Simple. Concentrate on Longevity of product. Which has been Lacking, at Least with The DiamondClean Series. Most Customers, Like myself; are Looking for a Rock Solid, Product. And Not Impressed, with unnecessary, worthless, added Features. To be honest, I am using This New DiamondClean Toothbrush, like an Old Model DiamondClean. In The Manual setting. I have extra Brush Heads, that I either purchased, or received at Christmas. That were for The Last Model Series. After that
If the Old Brush Heads, become unavailable, I will be doing research on Purchasing a New Toothbrush; On All different, Manufacturers; and models.

Too Gimicky
