The Philips Sonicare 9900 Prestige and DiamondClean 9000 are both high-end electric toothbrushes that offer advanced features and superior cleaning performance. However, there are some differences between the two models.
4 Key Differences between Philips Sonicare 9900 Prestige vs DiamondClean 9000 Specs
1. iSense vs Bluetooth Technology
The key difference is that the Philips Sonicare Prestige 9900 employs a new technology called SEnse IQ while the Sonicare 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.
The Sonicare 9900 SEnse IQ technology allows better brushing habits by detecting the cleaning motions and pressure used during brushing, as well as monitors brushing duration and frequency.

2. Design
In terms of design, 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 indicate the current intensity level
2. Brush heads
The Philips Sonicare DiamondClean 9000 comes with a single Premium Plaque Defence head; 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
The Philips Sonicare 9000 comes with a stylish charger glass that plugs into a regular shaver socket, while the Sonicare 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 traveling. The case can hold two brush heads, but it does not have a compartment to store the charging cable
4. Cleaning Performance
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.
Philips Sonicare 9900 Prestige removes 20 times more plaque than a manual brush but Sonicare 9000 Diamondclean removes 10 times plaque only.

- The 9900 is generally more expensive than the 9000.
- The Philips Sonicare 9000 is pretty quiet, creating as much noise as a regular oscillating brush at the highest intensity of its, but is quieter than the higher-end 9900 prestige.

Sonicare DiamondClean 9000 Review
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
Pros:
- good battery life,
- sleek design,
- ergonomic brush head,
- very quiet
Cons
- 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.
Which is better, the Philips Sonicare 9000 or 9900 Toothbrush?
In conclusion, both toothbrushes offer advanced features and superior cleaning performance. However, if you’re looking for a toothbrush with more advanced features like SEnse IQ technology that can help you improve your brushing technique and habits, then Philips Sonicare Prestige 9900 would be an ideal choice for you
