His latest creation, a sonic toothbrush, called the Sonicare DiamondClean 9000. New gadget or real oral hygiene device? This test is an opportunity to find out.

Philips Sonicare DiamondClean 9000: a stylish and well-equipped gadget

Elegance is the hallmark of Philips. For its new gadget, the firm has remained true to itself, opting for a very refined aesthetic. To adapt to everyone, it is available in 3 colors: white, black, pink and gold.

Its construction has been designed to facilitate its handling and ease of use. The Philips Sonicare DiamondClean 9000 brush comes with many accessories: 2 tips, 2 brush heads and 2 charging stations.


They have been designed to fit the brush heads into them. So, depending on how you want to use your toothbrush, you can choose which brush head you want to use.

Brush heads

Of the two brush heads, each is designed to perform a very specific role. The first brush head, the W3 Premium White, was designed to overcome all surface stains. As for the second brush head, the C3 Premium Plaque Control has the role of overcoming the most inaccessible areas of the teeth.

It is developed with a descaling capacity 10 times greater than most manual toothbrushes. To use either brush head, simply clip them onto the toothbrush head. Both are equipped with soft, but relatively dense strands.

Their configuration allows them to offer 4 times the coverage of a manual toothbrush, while the brush heads do the brushing work on their own. With their combined action, the Philips Sonicare DiamondClean 9000 is able to remove 100% of dental stains after 3 days of use.

Charging stations

As an electric brush, the Philips Sonicare DiamondClean 9000 incorporates a battery that needs to be recharged. In this regard, the manufacturer Philips has provided a charging glass on the one hand and a charging station on the other.

While the station is a small base on which the brush fits to be recharged, the charging glass, as its name suggests, comes in the form of a glass, in which you just have to place the brush . The advantage of glass in relation to the station is twofold: it can be used in the bathroom above the washbasin.

In addition, it thus creates the illusion of a classic toothbrush while it is charging. Speaking of recharging, you should know that the Philips Sonicare DiamondClean 9000 electric toothbrush has a long-lasting battery, capable of lasting 2 weeks of use in a single charge cycle.

Philips Sonicare DiamondClean 9000: the integrated controls

All controls of the Philips Sonicare DiamondClean 9000 electric toothbrush are integrated into its handle. These include commands such as:

  • the ON/OFF button;
  • the button to choose one of the 3 intensity levels;
  • the buttons to choose one of the 4 cleaning modes.

The 4 brushing modes

The Philips Sonicare DiamondClean 9000 electric toothbrush has 4 different brushing modes:

  • “Clean” for daily brushing;
  • “White+” to remove dental stains;
  • “Gum Health” to gently clean the gums;
  • “Deep Clean+” to brush teeth thoroughly.

The 3 levels of brushing intensity

Regardless of the mode used for brushing, the Philips Sonicare DiamondClean 9000 offers the possibility of regulating the intensity of the brushing each time. So you have the choice between 3 intensity levels (normal, medium, strong).

Philips Sonicare DiamondClean 9000: technologies, sensor and multimedia

What makes this toothbrush exceptional is certainly the panoply of ultra-efficient technologies that it embeds. There is in particular the sonic technology which intervenes directly in the brushing, the BrushSync technology and many others still which contribute enormously to the user experience.

sonic technology

This technology allows the head of the Philips Sonicare DiamondClean 9000, when the brush is turned on, to perform a sonic sweep that allows it to perform almost 62,000 movements per minute.

Each movement generates vibrations and each vibration produces microbeads so that the surface and the interdental space are cleaned gently, but deeply.

BrushSync technology

As with a non-electric toothbrush, brush heads are subject to wear after a number of uses and the Philips Sonicare DiamondClean 9000 is no exception. Thus, it is equipped with BrushSync technology.

The role of this is to inform you that the two brush heads have reached such a point of wear that they no longer provide optimal brushing efficiency. The alert is given via a yellow light, representing a brush head surrounded by two rotating arrows, just above the battery light.

This technology also participates in the selection of the different brushing modes provided for the Sonicare DiamondClean 9000. Indeed, it performs an automatic synchronization between the brush head used and the brushing mode that corresponds to it for maximum efficiency.

The integrated pressure sensor

For this electric toothbrush, Philips has provided an integrated pressure sensor. Its role is to indicate if the brushing is too strong by vibrating the device. Responding to a didactic approach, the presence of this sensor is intended to help the user use the gadget in the most efficient way possible. When the device vibrates, all you have to do is lower the level of brushing intensity by one notch among the 3 available to the electric toothbrush.

The progress report

Always with the aim of improving toothbrushing habits, Philips has developed the most innovative technology. Indeed, the whole brushing experience, including the action of the integrated sensor shown above, is listed in a personalized report that you can access via the Philips Sonicare mobile app.

It shows the level of efficiency of your brushing, as well as the good and bad habits, according to the modes and the level of brushing intensity.

Our review of the Philips Sonicare DiamondClean 9000 electric toothbrush

Considering the positioning of the Philips brand in the high-end niche, it may seem unreasonable to invest in a toothbrush at this price. However, everything suggests that this electric toothbrush far outperforms market competitors on several points.

Softness and efficiency

While respecting the sensitivity of the teeth, this toothbrush ensures effective brushing on the surface, but also between the teeth thanks to the rotational movement. It is also, to date, one of the few models to offer several brushing modes and several intensity levels, regardless of the mode used. This truly allows for very personalized brushing. As for the intensity sensor, there is nothing superfluous. On the contrary, it brings real added value.


Not only the shape, but also the technologies, the sensors and all the multimedia equipment of this brush greatly optimizes its daily use. Added to this is an impressive autonomy of 2 weeks, in normal use, and this, without any loss of efficiency. It must be emphasized, it is simply remarkable.

Small flat

Besides the price, the small downside with this Philips toothbrush is that it is not compatible with previous generations. If you had a previous model in the range, it is not possible to use the charging station for the Sonicare DiamondClean 9000. You are obliged to purchase the complete kit.

In short, apart from the small shadows mentioned above, this Philips toothbrush is definitely worth a look.
