The difference between the Philips Sonicare DiamondClean 9000 and the DiamondClean Smart 9300 represents the shift from a high-end, connected electric toothbrush to a real-time coaching system. They share the same beautiful design and basic connectivity, but the 9300 adds technology to actively teach you how to brush better.
Here is a detailed breakdown of the key differences:
1. Real-Time Guidance and Tracking (The Core Functional Difference)
This is the feature that justifies the price difference and defines the 9300 series:
- DiamondClean Smart 9300: Offers Advanced App Coaching. It uses smart sensors in the handle to provide real-time location feedback and guidance within the Sonicare app. This means the app acts as a mirror, showing you precisely where you are missing spots or where you need to spend more time, ensuring 100% coverage.
- DiamondClean 9000: Offers Basic App Tracking. It connects to the app to log your session duration, intensity, and pressure events. However, it does not provide real-time location mapping or guidance on missed areas.
2. Advanced Safety Sensors
The 9300 includes a more comprehensive sensor suite for protecting your technique:
- DiamondClean Smart 9300: Includes a Scrubbing Sensor in addition to the standard Pressure Sensor. This sensor alerts you (often via the app) if you are scrubbing back and forth with a manual motion instead of letting the sonic vibrations do the work, a common error that can damage gums.
- DiamondClean 9000: Relies primarily on the standard Pressure Sensor to alert you only when you press too hard.
3. Travel Case Convenience
The charging functionality for travel is upgraded in the Smart series:
- DiamondClean Smart 9300: Includes a premium USB Charging Travel Case. This means you can recharge the brush handle while it is stored inside the case by connecting it to a USB port, eliminating the need to pack the charging glass on short trips.
- DiamondClean 9000: Includes a Premium Travel Case for storage and protection, but it is not chargeable. You must bring the separate charging glass/base to recharge the brush.
4. Accessories and Bundle Value
The 9300 often provides a more complete selection of heads:
- DiamondClean Smart 9300: Usually includes a superior selection of three specialized brush heads (e.g., A3 All-in-One, C3 Plaque Control), allowing you to immediately utilize different modes effectively.
- DiamondClean 9000: Typically includes one or two brush heads in the box.
Core Similarities (The Excellent Shared Features)
It is important to remember that both models are high-end and share the following:
- Customization: Both offer the excellent combination of 4 Cleaning Modes and 3 Intensity Levels (12 total settings).
- Automation: Both feature BrushSync Mode Pairing, which automatically selects the correct mode for the attached smart brush head.
- Luxury Charging: Both include the elegant Charging Glass and Stand for the bathroom counter.
In summary, the DiamondClean Smart 9300 is the better tool for improving technique due to its coaching. The DiamondClean 9000 is the better choice for the user who wants maximum control and luxury without needing real-time guidance.

Philips Sonicare DiamondClean Smart 9300 Review
The Philips Sonicare DiamondClean Smart 9300 is a cornerstone of Sonicare’s flagship line, designed for users who want the absolute most advanced, customized, and coach-driven cleaning experience available. It is defined by its ability to provide real-time feedback that turns a simple chore into a mindful, guided oral care session.
Here is a deeper look at what makes the 9300 stand out:
Smart Coaching and Real-Time Feedback
The 9300’s primary purpose is to help you improve your brushing technique through data:
- App Connectivity & Personalized Guidance: The handle connects via Bluetooth to the Philips Sonicare app. During brushing, the app uses advanced sensors (Location and Scrubbing Sensors) to provide a 3D mouth map, showing you exactly where you have brushed, where you missed spots, and where you are over-scrubbing. This is far more advanced than the basic tracking found in lower models.
- Location Sensor: This sensor tracks the coverage across your teeth, guiding you to ensure you achieve 100% coverage in all 6 key areas of your mouth.
- Scrubbing Sensor: It alerts you if you are using an incorrect scrubbing motion (horizontal back-and-forth) instead of the gentle glide recommended for sonic brushes, helping protect your gums.
- Visual Pressure Sensor: A light ring on the handle flashes if you press too hard, immediately signaling you to ease up and protect your gums.
Maximum Customization and Automation
The 9300 gives you superior control over your cleaning intensity and focus:
- Cleaning Modes: It offers a wide selection of modes (4 Modes: Clean, White+, Gum Health, Deep Clean+).
- Intensity Levels: For each mode, you can select from 3 Intensity Levels (Low, Medium, High), giving you excellent personalization (up to 12 total combinations) to match your comfort level.
- BrushSync Mode Pairing: The handle automatically detects the type of smart brush head you attach (e.g., Premium Plaque Control) and sets the brush to the optimal mode and intensity.
Premium Design and Charging
The DiamondClean Smart series is synonymous with luxury accessories:
- Charging Glass: It includes the iconic and elegant charging glass, which doubles as a rinsing glass and charges the toothbrush when you simply place the handle into it.
- USB Charging Travel Case: For travel, the premium travel case not only protects the brush but also allows you to recharge the handle via a USB connection, making it highly convenient for road trips or international travel.
Summary
The DiamondClean Smart 9300 is designed for the user seeking a dental coach in a toothbrush. It is a major upgrade from the ProtectiveClean series, not just in aesthetics, but in its ability to give you the data needed to master your brushing technique for the best possible oral health outcomes.
Which is better, Philips Sonicare 9000 or 9300 Diamondclean?
The DiamondClean Smart 9300 is the better brush for oral health improvement because its app-based coaching and location sensors actively ensure 100% coverage and correct technique.
The DiamondClean 9000 is the better choice if you want the luxury aesthetic and maximum manual control but don’t feel the need for real-time guidance and app coaching.
