Choosing between Philips Sonicare’s DiamondClean 9300, 9500, 9700, and 9900 Prestige can feel confusing—they look identical and all claim “smart” technology. Here’s what Philips won’t tell you clearly: the 9300, 9500, and 9700 have identical brushing technology. You’re paying more for extra brush heads and accessories, not better cleaning. Last Updated: November 11, 2025 | Black Friday Deals Live Now
The exception? The 9900 Prestige introduces genuinely new SenseIQ AI powered technology a leap beyond coaching that automatically adjusts to your technique when you brush too hard—a real upgrade, not just a bigger bundle.
Stop overspending on identical technology. We cut through the confusion to show you which model offers the best value bundle (9300 vs. 9500 vs. 9700) and whether the 9900 Prestige’s fully automated defense system is the right investment for your smile.
Black Friday Reality Check: The 9700 is currently $279 (down from $338) with 8 brush heads included—that’s $120+ in free accessories. The 9300 at $199 offers the same smart coaching but you’ll buy heads separately. The 9900 Prestige at $299 (21% off) is the smartest buy if you want fully automated protection.
This guide shows you exactly which model delivers the best value for your budget during Black Friday 2025.
Key differences between Sonicare Diamondclean 9300 , 9500 , 9700 and 9900 Prestige
The key to understanding these models is recognizing that the 9300, 9500, and 9700/9750 share the exact same Smart Sensor technology and coaching features. The difference among these three is purely the accessory bundle. The 9900 Prestige represents the next generation of technology with its adaptive SenseIQ.

1. Philips Sonicare 9900 Prestige (Newest Generation)
Philips Sonicare 9900 Prestige: This is the most advanced and recent model. Its key differentiator is the SenseIQ technology. This system goes beyond the smart sensors of the other models by automatically sensing your brushing style (pressure, motion, and coverage) and adapting the intensity of the brush in real-time. It offers a more seamless and personalized experience. The 9900 Prestige also has a more streamlined design with a single “seamless” button and a smaller, more compact charging puck and travel case (with USB-C charging), making it more convenient for travel. It also has a “Sensitive” mode, which some other models may not have.
9900 Prestige automatically adapts the brushing intensity if you push too hard or use excessive motion, providing a more hands-off, personalized experience. It has a sleeker design and uses a single, All-in-One A3 brush head intended for all tasks. Its charging accessories are also more premium/travel-focused (charging puck and USB-C case).
The Philips Sonicare 9900 Prestige represents a significant upgrade due to its exclusive SenseIQ Technology. While the DiamondClean Smart brushes simply alert you when you push too hard, the SenseIQ in the 9900 Prestige actively senses, adapts, and cares for your brushing. This means it can automatically adjust the brushing intensity in real-time when it detects excessive pressure or scrubbing motion.
Other differentiators for the 9900 Prestige include:
- A simplified brushing experience, often using a single A3 Premium All-in-One brush head that negates the need to switch between specialized heads for different modes.
- A slimmer, more compact handle design with a seamless button.
- More modern accessories, such as a compact leatherette travel case with USB-C charging and a charging puck (instead of the older charging glass).
DiamondClean Smart Series (9700, 9500, 9300 – Previous Generation)
The 9700, 9500, and 9300 models are all part of the DiamondClean Smart series. They offer a comprehensive, personalized experience primarily through their smartphone app, which tracks coverage, pressure, and scrubbing.
The differences between the 9700, 9500, and 9300 are subtle and mainly focus on the accessories and cleaning modes:
- Philips Sonicare 9700 was the previous top-tier model. It offers a comprehensive, guided experience with the Sonicare app, including scrubbing and location sensors (like the 9900 Prestige’s predecessor, without the auto-adjustment). It typically includes the most brush heads (8) and has all 5 cleaning modes, including the dedicated TongueCare+ mode and brush head. It typically comes with a premium glass charger.
- Sonicare 9500 (DiamondClean Smart) is an upgrade from the 9300: Very similar to the 9700, the 9500 offers the same 5 cleaning modes (including TongueCare+), but comes with fewer included brush heads (often 4).
- Sonicare 9300 (DiamondClean Smart): The most basic of this “DiamondClean Smart” line. It retains the core smart features like the pressure sensor, multiple modes, and app connectivity, but lacks the dedicated TongueCare+ mode/head and typically comes with fewer brush heads (3 total) compared to the 9500 and 9700.). It also uses the charging glass.
In summary, the 9900 Prestige focuses on advanced adaptive automation (SenseIQ) and a more streamlined, premium design. The 9700/9500/9300 models focus on manual mode selection with real-time feedback and feature variety, with the higher numbers simply indicating more included accessories and modes.
Key features common to the DiamondClean Smart Series (9300, 9500, 9700):
- Smart Sensor Technology: Utilizes built-in sensors and Bluetooth connectivity to provide real-time feedback via the Philips Sonicare app. This includes a pressure sensor that alerts you when you’re brushing too hard and a location sensor that helps you track your brushing coverage.
- Multiple Modes and Intensities: All models in this series offer various brushing modes (Clean, White+, Gum Health, Deep Clean+) and multiple intensity levels to customize the cleaning experience.
- BrushSync Technology: The toothbrush handle automatically recognizes the type of brush head attached and selects the appropriate mode. It also tracks the brush head’s usage and reminds you when it’s time for a replacement.
- Accessories: The higher-end models typically include a charging glass and a premium travel case that doubles as a charger.
- In short:
- If you want the latest, adaptive technology and a streamlined design, choose the 9900 Prestige.
- If you want the most dedicated modes and a full suite of accessories (including Tongue Care), the 9700 or 9500 are the best fit.
- If you want a full-featured smart brush without the TongueCare+ mode, the 9300 is an excellent choice.
Philips Sonicare Diamondclean Smart Review
The Philips Sonicare DiamondClean Smart series (models 9300, 9500, 9700/9750) represents the absolute pinnacle of Philips’ previous generation of sonic technology, focusing on transforming the manual act of brushing into a data-driven, coach-guided oral care routine.
It is the definitive choice for users who want to eliminate guesswork and actively improve their technique.
The Core Defining Technology: Smart Sensors and App Guidance
The essence of the DiamondClean Smart series lies in the integration of specialized sensors with the Sonicare app:
- Real-Time Coaching: The handle connects via Bluetooth to the app, which uses advanced Location Sensors to map your mouth. The app acts as a digital mirror, showing you precisely where you are brushing, where you are applying too much pressure, and, critically, where you are missing spots. This visual feedback is key to achieving 100% coverage.
- Safety Sensors: These models include a suite of protective sensors:
- Pressure Sensor: A light ring on the handle flashes brightly if you press too hard, protecting your gums and enamel.
- Scrubbing Sensor: Alerts you through the app if you are using an incorrect back-and-forth scrubbing motion, guiding you to use the correct gentle glide.
- BrushSync Automation: The handles use BrushSync Mode Pairing, automatically recognizing the attached smart brush head (e.g., Plaque Control or Gum Care) and selecting the optimal mode and intensity for that head.
Maximum Customization
The DiamondClean Smart series offers total control over your cleaning:
- Mode Versatility: Depending on the model (9300, 9500, etc.), you get 4 or 5 cleaning modes (Clean, White+, Gum Health, Deep Clean+, and Tongue Care on the 9500/9700).
- Intensity Control: For each mode, you can select from 3 Intensity Levels (Low, Medium, High). This provides up to 15 unique cleaning configurations, allowing you to fine-tune the power for any sensitivity issue.
Premium Accessories and Design
True to the DiamondClean name, these brushes offer a luxury experience:
- Dual Charging: They typically include both the elegant Charging Glass and Stand for counter use and the highly convenient USB Charging Travel Case that recharges the handle while it’s stored for travel.
- Premium Brush Heads: They use the newer line of high-performance Premium brush heads (like the A3 All-in-One and C3 Plaque Control), designed to maximize plaque removal and gum health.
In summary, the Sonicare DiamondClean Smart is a complete oral hygiene system that leverages data and connectivity to turn guesswork into certainty, ensuring you get the most effective clean possible.
Which is better, Philips Sonicare Diamondclean Smart or 9900 Prestige?
For ultimate performance, the Sonicare DiamondClean 9900 Prestige is technically the best because it utilizes next-generation SenseIQ technology, which automatically adjusts the brushing intensity in real-time if you press too hard, offering superior protection beyond the alert-only feature of the Smart series; however, the 9700 is arguably the best overall value as it provides the full suite of advanced smart coaching features (5 modes, app-guided location sensing) and the most comprehensive accessory bundle, typically including a full year’s supply of brush heads, while the 9300 and 9500 offer the same excellent coaching technology but with fewer included accessories.
