Performance

[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

I am very pleased with the performance of the toothbrush.
My teeth feel very clean are brushing with this toothbrush. 

My only complaint is that after purchasing this brush, I feel that a tongue brush should have come with this model. I know some models have it.

Diamond Clean Smart Electric Toothbrush

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

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...

I was super excited to get this toothbrush from all of the great reviews I read previously, but I am disappointed with a few of its features. When using the toothbrush, the timing is never long enough.

When using the "count down feature/where you should be brushing" on the app, it always says I missed two sections of my teeth after following the instructions. It has a set time for each section, so it runs out of time before getting to all of the sections of the mouth. Why wouldn't the brush timer last long enough to get every section of the mouth? This has caused me to use the toothbrush at least two times every time I brush, meaning I brush my teeth "twice" in the morning and "twice" at night. 

This causes the brush heads to get used up so quickly --because they tell you to change it after 180 uses. (Otherwise it reminds you every day it needs to be changed!) Divide that by 4 and it will only last 45 days. For the price of the brush heads, these toothbrushes should be lasting longer than just 45 days. I am disappointed I paid so much for this product and have to continually pay for the expensive brush heads so often.

Too short of brushing time

I had a diamondclean for a couple of months that stopped working properlt adter a drop in the sink. I dis not register it for warantee protection and was a little disappintef that it was so succeptible yo famage by such a little mishap
Nevertheless, i liked how it cleaned and bought another
I find the iphone stnc business to be nothing more than a silly gimmick, and find your repeated prompts to synch my brushjead on the phone to be annoying
Also, i liked the old brush's four X 30 second timing prompt cycle
The new one seems to have six or more 20 second prompts
It seems to be irregular, and one stopwatch experiment the cycles lasted for over 2.5 minutes. That is too long, and the multiple changes are a distraction. I find myself losing track and wondering, was that 4 or 5? Then shutting it down. 4 cycles - and two minutes seened easier to deal with and 2-minutes seemed plenty 
If there is a way to change this, let me kno

Cycle duration too long long

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

I loved my sonicare toothbrushes over the years, but when it died, which all of mine have in about 2 years, I got the new one. I want to go back to the old one. Who cares if it flashes on the bottom and I could care less if there's an app, I just want my teeth to be and feel clean, and I think the diamond version I had before all the flashing was better. My teeth felt cleaner.

Don't like the newer version

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
