Philips Sonicare 9900 Prestige vs DiamondClean 9000 Comparison Review

The key difference between Philips Sonicare Prestige 9900 and 9000 DiamondClean is that the Sonicare 9900 Prestige has a new technology called SEnse IQ that allows for better brushing habits by detecting the cleaning motions and pressure used during brushing, as well as monitoring brushing duration and frequency.

These sessions can be tracked through the Sonicare app while the 9000 Diamondclean only uses Bluetooth connectivity to the Sonicare app that only logs in your brushing sessions but does not really coach you to improve your cleaning technique like the 9900 does.

Philips Sonicare 9900 Prestige vs DiamondClean 9000 Design Difference:

The Philips Sonicare DiamondClean 9000 has a contemporary and stylish design that is similar to the Sonicare Prestige 9900, but it is larger in size. This is due to the extra settings that are available on the handle.

Additionally, the 9000 has a button on the lower half of the handle that allows you to select a mode and intensity level, while the 9900 requires you to use the Sonicare mobile app to make changes.

The Sonicare 9000 also has an LED on the lower half of the handle that indicates the current mode and four small bars on top of the handle that indicates the current intensity level.

2. The difference in the number of brush heads you get:

The DiamondClean 9000 comes with a single Premium Plaque Defence head, but Philips offers a variety of four different brush heads to meet different needs. The Prestige 9900, on the other hand, uses all-in-one brush heads, so there is no need to combine and match for various purposes. However, you can configure the brush through the mobile app if you want a different type of cleaning experience.

3. Glass vs USB Charger differences:

The DiamondClean 9000 comes with a stylish charger glass that plugs into a regular shaver socket, while the Prestige 9900 comes with a USB leather-effect case that looks like a small umbrella and can keep your brush safe and charged while you’re travelling. The case can hold two brush heads, but it does not have a compartment to store the charging cable.

4. Performance differences:

In terms of cleaning performance, the Prestige 9900 is considered to be stronger and more effective in removing tough stains and plaque compared to the DiamondClean 9000.

Which is better, Philips Sonicare 9900 or 9000?

In conclusion, both the Philips Sonicare DiamondClean 9000 and Prestige 9900 are high-end electric toothbrushes that offer advanced features and superior cleaning performance. However, the DiamondClean 9900 has superior features like the Sense IQ that can help you improve your brushing technique and habits.

The Philips Sonicare 9900 Prestige is a toothbrush that pairs with a companion app to offer intel on brushing. It allows for changing intensity settings, switching between modes, using adaptive intensity, and providing scrubbing feedback. It also includes a brush handle, one brush head, a traveling case that also charges it, an at-home charging base, and a charging cable and plug. To access the connected experience, you need to obtain the Philips Sonicare app.

  • It utilizes a Bluetooth connection between the phone and the brush to personalize options, observe progress, and receive recommendations
  • Has a single brush head, Phillips’s new premium all-in-one brush head model 83, which replaces other brush head options
  • Has Brush Sync technology
  • 3 intensity settings: high, medium, and low
  • Sense IQ is Phillip’s catchall phrase for the array of technology in this brush, which includes adaptive intensity, pressure sensor, and scrubbing feedback
  • Scrubbing Feedback/Pressure Sensor: toothbrush can intelligently evaluate brushing movements and pinpoint “scrubbing behavior”, the brush will reduce the intensity setting if using excessive pressure for too long, pressure sensor changes vibration and light when pushing too hard
  • App captures Brushing Frequency, Average Brush Time

Overall, a great toothbrush with many options; It is easy to use, stores data, is comfortable, and has a soft brush head.

 Sonicare DiamondClean 9000 Review

Last update on 2023-06-07 at 13:24 / Affiliate links / Images from Amazon Product Advertising API

The Sonicare DiamondClean 9000 is a good brush for cleaning performance. The emphasis of its app is on organizing a dental hygiene regimen, not on improving brush technique. Some info is replicated on the brush handle itself, such as battery life, mode, brush top type, and intensity. It has 4 brushing modes: clean, deep clean+, gum health, and white+. You can toggle between modes by pressing the button below the power switch but must stop brushing to shift modes. The handle will automatically choose best mode based on brush top used, but different brush heads for whitening, plaque removal, etc, must be purchased separately


  • good battery life,
  • sleek design,
  • ergonomic brush head,
  • very quiet


  • few style options,
  • app can include more features

Overall a great brush with many cleaning options and good accessories. For people who are more interested in thoroughly cleaned teeth, there are plenty of cleaning modes available to achieve optimum combination for good dental health.
