Technical Details

Full Review

The Philips Sonicare DiamondClean 9000 Electric Toothbrush has the WOW factor. It really does.

This state of the art electric toothbrush has multiple functions that make brushing your teeth easier, simpler and with much more efficiency.

Philips is one of the leading brands in the dental industry, with a solid reputation of giving its customers the very best money can buy.

This review is long term and I’ll give you detailed feedback of my trial.

Holding the Philips DiamondClean 9000 Electric Toothbrush

No question, it’s a beautiful electric toothbrush.


Philips Sonicare DiamondClean 9000 is a feature-rich product.

So often when there is a multitude of functions, a product can become quite difficult to operate. This is not the case with the Diamond Clean 9000 electric toothbrush.

There are 4 distinct functions or features that you need to know about.

  1. Built-in pressure sensor
  2. Smart brush head recognition
  3. 4 modes, 3 intensities
  4. Connected brushing made easy – App Connectability

The Philips 9000 Electric Toothbrush has features that make a world of difference when brushing your teeth. Let me dive deeper and touch on these features in little more thoroughly.

The C3 Premium Plaque Control brush head provides the deepest possible clean. Its “soft, flexible bristles are designed to curve around the contours of your teeth”. Philips states you can remove “up to 10x more plaque removal from hard-to-reach spots”.

Philips 9000 is intelligent and connects to the Sonicare App which allows you to monitor and improve your brushing over a period of time.

The BrushSync heads automatically select the best brushing mode for you. Though, you can change it easily with a push of a button.

Another great feature of this BrushSync technology is the ability to indicated when it is time to replace your brush head. As you brush it keeps a track of the time and pressure when in use, providing a warning light and short beep to give you the heads up it’s time for a change.

My First Impressions – DiamondClean 9000

As soon I got this product in my hands I knew it was going to be good, it had that luxurious feel to it.

Beautifully presented with everything you need to get your brushing in order.

The brush heads are wonderful. The shape that Philips has used for the brush head is very close to a normal toothbrush, just a little smaller and much more refined.

Holding this 9000 electric toothbrush is a dream and it sits perfectly balanced in the palm of your hand. There is also some weight to it, showing in my mind, that it’s quality.

The pressure control has been perfected and offers a gentle yet decent warning when I brushed too hard. The sound it gives is just enough to encourage better brushing.

Charging is simple and extremely efficient, with 2 ways to charge making it quite versatile.

Packaging and Design

The DiamondClean 9000 comes in a stylish package, and everything is laid out inside beautifully.

There is reduced plastic packaging which I noted straightaway and approved of wholeheartedly. The toothbrush and contents are protected by way of paper/cardboard mache. Great idea and something that is much more environmentally friendly.

The design of the 9000 DiamondClean is amazing. From brush head to handle, the components are made very well.

The Brush Heads

With your DiamondClean 9000, you’ll get two brush heads. One for general cleaning and the other designed to whiten your teeth.

I appreciated the fact that it came with 2 brush heads that I could use. Electric toothbrushes in the past have given me trouble in terms of sensitivity. Both of these brush heads that are offered with the electric toothbrush are soft on my teeth and gums.

The Philips Sonicare DiamondClean 9000 Handle

As soon as you pick up the DiamondClean 9000 handle, straightaway you realise it is well made and solid.

Finished in a matte texture, it is a pleasure to use and hold.

The function buttons are conveniently located and easy to operate. The indicating lights have a softness to them and aren’t overwhelming to look at.

When the handle vibrates, either because you are brushing too hard or it’s time to change your brushing area, it’s a pleasant sound.

Overall the handle is probably the best I’ve held in the electric toothbrush market.

Charging and Preparation

You have 2 options when it comes to charging your Philips DiamondClean 9000 Electric Toothbrush.

I have mostly used the glass jar charge, that comes in two parts; 1. Glass jar and 2. The charging base.

It’s so simple and really easy to get a full charge while you sleep. You just place your 9000 in the jar and it will indicate charging has started with a short little vibration, beep and light up of icons on the handle.

The second charging option is the sleek travel case. Designed to house 2 brush heads and your DiamondClean 9000 handle, it’s a great method of charging is you are travelling or lack space in your bathroom cupboard.

The great thing with the charging capability of the DiamondClean 9000 is that a full charge will give you 14 days of use. This obviously is dependant of how long you brush for but it’s based on brushing for 2 minutes, morning and night.

Bluetooth and App Features

A stand out feature of this electric toothbrush is no doubt the Bluetooth compatibility and Sonicare App.

Both work hand in hand to streamline and record your daily brushing, so that you may check and alter brushing timeframes or maybe even technique.

Thorough instructions are presented in the instructional booklet in the box and it’s pretty simple to set up.

For this review period, however, I focused more on the product and how it brushed and didn’t use the app much. My finds on the App and Bluetooth function will be stated in detail later in an update on this post.

Price and Value

The price for a 9000 DiamondClean toothbrush does vary quite considerably. Just depends if a retailer has a sale on etc.

The RRP is $379.00. However, after a quick google search of the brand and product name, the average price to date is $279.00.

One point I will make is that this product is made so well and with regular cleaning and proper care, the DiamondClean 9000 should last for many years.

Given that, when this electric toothbrush is on sale for under $300, I believe it represents great value for money.

Testing the Philips Sonicare DiamondClean 9000 Toothbrush

This review has been over a period of 3 months plus. I’ve included this toothbrush in my oral hygiene routine, morning and night.

Below are some insights and thoughts that I had while I was testing and review this electric toothbrush by Philips.

Usage Timeline

  • Initial Usage
    Condition: Excellent

    The design and quality of the Phillips 9000 is definitely noticeable.

    Very luxurious and stylish, top-end product feel.

    First brushing experience was great, very gently vibrations while brushing is I like.

  • 2 Weeks of Use
    Condition: Excellent

    The electric toothbrush is probably the best I've used. Wonderful to hold and handle, plus it gives an awesome clean. My teeth are feeling very refreshed after a brush with this product.

    If I don't close my mouth most of the way, the vibration of the brush does tend to splatter toothpaste everywhere. A bit more noticeable than other electric brushes  I've tried.

    I've only charged it once at the start of the trial and it's still going... getting close to a recharge.

  • 1 Month of Use
    Condition: Great

    Still enjoying brushing my teeth with the Philips DiamondClean 9000. Really does a superb job!

    To good thing is, you can use it just like a regular toothbrush but also having the benefit of letting the toothbrush head vibrate and clean. 

    I'm consistently reminded of the quality of the toothbrush. It's solid but refined. 

    I've swapped the brush heads a bit. Both are great at cleaning, with the whitening one having a more polishing centre of bristles.

  • 3 Months of Use
    Condition: Great

    Phillip 9000 has held up very well over the course of my trial. It's a pleasure to hold and use.

    The brush heads are great quality and are not wearing that much, I tend to try to brush softly and let the functions do their thing.

    I haven't used the Sonicare App much, but plan to provide further information and review notes on this next.

    The charging options work very well. Having the glass jar and charging base in my bathroom is my preferred option. The travel case is great for when you are travelling for work, on holiday or needing to conserve space in the bathroom.

    General cleaning is a must after use, as toothpaste buildup can occur causing your 9000 to look shabby. I have tried to rinse and wipe it in the evenings so it's fresh for next day 🙂


I was really impressed with the Philips Sonicare DiamondClean 9000 Electric Toothbrush.

The product is designed and made to the highest quality, with functional features that work that make brushing your teeth more enjoyable.

Whether you are a person who likes all the bells and whistles, or someone that needs simplicity in a product, the DiamondClean 9000 is a toothbrush that will work for you.
