Oral B IO Series 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison

The Oral-B iO Series 5 through 10 are tiered by their handle display, charging speed, and A.I. tracking depth, while all maintain the same powerful iO Magnetic Drive System and core cleaning performance.

The entry-level smart options (iO 5 and 6) provide 5 cleaning modes, A.I. tracking via the app, and a visible pressure sensor; however, the iO 5 uses simple backlit icons, while the iO 6 steps up to an Interactive Black & White Display. Charging speed is slow for both, using a standard magnetic stand that can take up to 16 hours for a full charge, making them the most budget-friendly way to access the iO cleaning technology.

The premium and flagship models (iO 7 through 10) all feature the crucial upgrade of 3-Hour Fast Charging and progressively enhance the user experience. The iO 7 retains the Black and white display and 5 modes, but adds fast charging. The iO 8 introduces the highly desirable Full Colour Interactive Display and ups the mode count to 6.

The flagship iO 9 and iO 10 share the ultimate handle features: the colour display, the maximum 7 cleaning modes, and top-tier 3D Position Detection (16-zone tracking). The iO 10 is set apart only by its iO Sense Smart Charger, which provides the real-time A.I. coaching directly on the charging base, eliminating the need to use the smartphone app during brushing.

Oral B IO Series 5 vs 6

The Oral-B iO Series 5 and Oral-B iO Series 6 are both entry-level models in the premium iO line, meaning they share the fundamental magnetic cleaning power and excellent core features but differ primarily in the sophistication of the handle display and the refinement of the pressure sensor/app feedback.

Key Differences

• Handle Display: This is the most noticeable difference.
  • The iO Series 5 has a more basic LED display that uses simple icons or coloured lights to indicate modes, pressure, and battery level.
  • The iO Series 6 features an Interactive Black and White Display (often described as monochrome or an advanced OLED). This display provides clearer text/visual feedback, can greet you, and often uses visual cues like a smiley face to grade your brushing performance, making it more engaging.
• Pressure Sensor Feedback: The refinement of the pressure control differs slightly.
  • The iO Series 5 uses the multi-coloured light ring and the app to show if you are brushing too hard or too soft.
  • The iO Series 6 has a smarter pressure sensor that not only uses the light ring but also provides more detailed feedback in the app and may even slow down the rotation of the brush when you push too hard, offering greater protection.
• Cleaning Modes: This can vary by retailer/region, but generally:
  • The iO Series 5 typically offers 5 cleaning settings (Daily Clean, Sensitive, Whitening, Intense Clean, Super Sensitive).
  • The iO Series 6 also offers 5 cleaning settings (often including Gum Care, which may be swapped for one of the others), which can be selected more easily via its clearer interactive display.

Core Similarities

• Cleaning Technology: Both use the identical iO Magnetic Drive System for a professional clean, combining oscillating movements with gentle micro-vibrations.
• Plaque Removal: Both deliver the same excellent results, removing significantly more plaque than a manual brush.
• A.I. Tracking: Both models include A.I. Recognition and Bluetooth connectivity for real-time tracking and personalized coaching via the Oral-B app.
• Core Accessories: Both generally include a basic charging dock and a travel case or pouch.

In summary, the iO Series 5 is the better choice for the budget-conscious user who wants the core iO clean and app tracking. The iO Series 6 is a worthwhile upgrade for those who want a more informative, interactive, and refined experience on the brush handle itself.

Oral B IO Series 5 vs 7

The Oral-B iO Series 5 and Series 7 differ primarily in handle display, charging technology, and on-handle guidance.

The iO Series 5 is the most affordable entry point to the iO line, offering 5 cleaning settings (Daily Clean, Intense Clean, Sensitive, Super-Sensitive, Whitening) and all the core technology. However, it features a more basic LED Light Ring Timer and Refill Change Alert rather than a full screen, relying mostly on the mobile app for guidance and feedback. It also uses the standard charger, which means a long charging time (typically up to 16 hours).

The iO Series 7 is a significant upgrade in user experience and convenience. It maintains the 5 cleaning modes but upgrades the handle with an Interactive Black & White Display that visually communicates mode settings, charging progress, and greets you, providing better guidance without needing the app. Crucially, it includes the 3-Hour Fast Charger and travel case, making it far more convenient for users who need quick power-ups.

In summary, the iO Series 5 is the value option, providing the exact same cleaning power while omitting the advanced display and fast-charging capability. The iO Series 7 is the better mid-range option, adding a visual display and the essential 3-hour fast charging for superior day-to-day usability.

Oral B IO Series 6 vs 7

The comparison between the Oral-B iO Series 6 and the Oral-B iO Series 7 highlights the single most important functional upgrade in the iO line: the transition to fast charging. They share the same display and cleaning technology, making charging speed the deciding factor.

The Oral-B iO Series 6 and Series 7 differ primarily in charging speed and included charging accessories.

The iO Series 6 is the upper-value model. It offers all the core technology of the premium line, including the Interactive Black and White Display, 5 Smart Brushing Modes, the A.I. powered app for real-time tracking (6-zone tracking), and the smart pressure sensor. However, it uses the older, standard charging stand, which requires a long charging time, typically up to 16 hours, to fully recharge. This makes it a great choice if you leave your brush on the stand permanently.

The iO Series 7 introduces the first premium upgrade to the line: the 3-Hour Fast Charging feature via its new magnetic charging stand. This makes it ideal for users who travel frequently or want to quickly top off their battery. The Series 7 retains the same Interactive Black and White Display and 5 Smart Brushing Modes as the Series 6, ensuring the same quality of clean and A.I. guidance.

In summary, the iO Series 6 is the budget-conscious choice for those seeking premium features without the convenience of fast charging. The iO Series 7 is the entry point to the full Fast-Charging experience in the iO line, offering identical cleaning power and display but significantly superior charging speed.

Oral B IO 6 vs 8

The comparison between the Oral-B iO Series 6 and the Oral-B iO Series 8 shows a distinct jump from the upper-value tier to the premium tier. They both deliver the same core iO magnetic cleaning power, but the Series 8 is superior in display technology, charging speed, and customization.

• Pressure Sensor: Both feature the Smart Pressure Sensor (light ring) that alerts you if you are applying too much or too little pressure.

The iO Series 8 is the recommended upgrade if you value a full-colour interface and the convenience of fast charging. The iO Series 6 is an excellent value choice if you can live with the monochrome display and standard charging time, as the core cleaning power is the same.

Oral B IO 6 vs 9

The comparison between the Oral-B iO Series 6 and the Oral-B iO Series 9 represents the jump from the upper-value tier directly to the flagship tier. While they share the foundational iO Magnetic Drive System and core cleaning power, the Series 9 is superior in display technology, A.I. sophistication, number of cleaning modes, and premium accessories.

Key Differences (The Flagship Upgrades)

Monochrome/Black & White Display	Full Colour Interactive Display
A.I. Recognition (6-zone tracking)	3D Position Detection (16-zone tracking)
5 Smart Brushing Modes	7 Smart Brushing Modes
Standard Charging Stand, Simple Travel Case	Magnetic Fast Charging Stand, Charging Travel Case
Up to 16 hours (Standard) Charging Time	approx 3 Hours (Fast Charging)

• Display Quality: The iO Series 9 features a Full Colour Interactive Display, which is much clearer and more engaging than the iO Series 6’s monochrome screen. This improves navigation and visual feedback significantly.
• A.I. Tracking: The iO Series 9 uses 3D Position Detection, which tracks brushing across all three surfaces of each tooth for the most comprehensive coverage report (16 zones). The iO Series 6 uses a simpler A.I. Recognition technology, typically tracking 6 zones.
• Cleaning Modes: The iO Series 9 offers the maximum 7 cleaning modes, including specialized options like Tongue Clean and Super Sensitive, giving you the most customization. The iO Series 6 offers 5 cleaning modes.
• Accessories: The iO Series 9 comes with a Charging Travel Case and a Magnetic Fast Charging Stand (often charging in about 3 hours). The iO Series 6 usually includes a non-charging travel case and a standard induction charger (which can take up to 16 hours).

Core Similarities

• Cleaning Technology: Both use the identical, high-performance iO Magnetic Drive System for the deepest clean, combining oscillation with micro-vibrations.
• Pressure Sensor: Both feature the Smart Pressure Sensor (light ring) that alerts you if you are brushing too hard or too soft.
• Connectivity: Both are Bluetooth-enabled and connect to the Oral-B app for coaching and logging your sessions.

In summary, the iO Series 9 provides a significant leap in features and convenience—from a full-colour screen and 3D tracking to fast charging—making it the top-of-the-line experience. The iO Series 6 offers the same great cleaning power at a better value, sacrificing the premium display and advanced tracking features.

Oral B IO 7 vs 8

The Oral-B iO Series 7 and Oral-B iO Series 8 sit next to each other in the premium segment of the iO line. They deliver the same foundational iO magnetic cleaning power and core smart features, but are separated by differences in the handle display and mode count.

Here is the comparison and contrast:

Key Differences (The Feature Upgrades)

Oral-B iO Series 7	Oral-B iO Series 8
Interactive Black & White Display	Full Colour Interactive Display
5 Smart Brushing Modes	6 Smart Brushing Modes

• Display Quality (Most Significant): The iO Series 8 features the Full Colour Interactive Display (OLED), which offers a more visually rich and engaging user experience with vibrant colours for mode selection, greetings, and feedback. The iO Series 7 features an Interactive Black & White (Monochrome) Display, which is functional but lacks the colour distinction of the Series 8.
• Cleaning Modes: The iO Series 8 expands the customization options by offering 6 Smart Brushing Modes, while the iO Series 7 offers 5 Smart Brushing Modes. This extra mode on the Series 8 (often “Super Sensitive” or a similar specialized option) is ideal for those requiring maximum personalization.

Core Similarities

• Cleaning Technology: Both models utilize the identical, high-performance iO Magnetic Drive System for a professional clean that combines oscillation with gentle micro-vibrations.
• Plaque Removal: Both are highly effective, removing 100% more plaque than a manual toothbrush.
• A.I. Tracking: Both include A.I. Brushing Recognition and Bluetooth connectivity to the Oral-B app for real-time tracking, typically focusing on 6-zone coverage.
• Pressure Sensor: Both feature the Smart Pressure Sensor (light ring) that illuminates to indicate the correct brushing pressure.
• Fast Charging: Both models include the Magnetic Charger capable of providing 3-Hour Fast Charging, which is a major convenience feature.

The iO Series 8 is the superior choice for users who want the full-colour interface and the benefit of an extra specialized cleaning mode. The iO Series 7 provides excellent performance and fast charging at a better price point, sacrificing only the colour display and one cleaning mode.

Oral B IO 7 vs 9

The Oral-B iO Series 7 and Series 9 differ primarily in A.I. technology, display sophistication, and mode count.

The iO Series 7 is an excellent mid-range choice, offering the essential smart features and fast charging. It comes with 5 cleaning modes and an Interactive Black & White Display on the handle. Its A.I. technology uses A.I. Brushing Recognition for general coverage tracking across 6 zones of the mouth. It includes the 3-Hour Fast Charger and a standard travel case.

The iO Series 9 is the premium flagship model, elevating the brushing experience with its advanced features. It includes 7 cleaning modes (adding specialized modes like Tongue Clean and Super Sensitive) and a superior Full Colour Interactive Display. The most significant upgrade is the 3D Position Detection (3D Tracking), which uses A.I. to track brushing across all three surfaces of every tooth (16 zones) for the most detailed feedback on your technique. It typically includes a Charging Travel Case and the Magnetic Fast Charger.

In summary, the iO Series 7 is a powerful and efficient model that provides the core iO clean and fast charging. The iO Series 9 is the most advanced option, adding a full-colour screen, the maximum 7 modes, and the industry-leading 3D teeth tracking for the ultimate personalized cleaning guidance.

Oral B io8 vs io9

The Oral-B iO Series 8 and Series 9 differ primarily in A.I. tracking sophistication, mode count, and the included travel case.

The iO Series 8 is an almost-flagship model, offering all the essential premium features, including a Full Colour Interactive Display, the Magnetic Fast Charger, and a total of 6 cleaning modes. Its A.I. tracking provides real-time guidance using a general A.I. Recognition method (typically tracking 6 zones) in the app. The Series 8 typically comes with a standard travel case or pouch.

The iO Series 9 is the top-tier model, designed for maximum tracking and customization. It upgrades the tracking system to 3D Position Detection (often tracking 16 zones: the front, top, and back of every tooth), giving the most detailed feedback in the app. It provides the maximum of 7 cleaning modes (adding the specialized Tongue Clean mode). The Series 9 typically includes a Charging Travel Case, allowing you to recharge the handle on the go.

In summary, both brushes deliver the same excellent cleaning performance and share the key feature of a full-colour screen and fast charging. The iO Series 9 is the more advanced option, adding the 7th mode and the superior 3D tracking for dedicated users, and a charging travel case for convenience. The iO Series 8 is the better value choice, providing nearly all the same functionality for a significantly lower price.

Oral B IO Series 9 vs 10

The Oral-B iO Series 9 and Series 10 differ primarily in the charging dock’s intelligence and resulting real-time guidance experience.

The iO Series 9 is the flagship-level handle, featuring a Full Colour Interactive Display, the maximum 7 cleaning modes, and industry-leading 3D Position Detection (16-zone tracking) for detailed feedback via the Oral-B app. It comes with a standard magnetic charger (providing approx 3-hour fast charging) and a Charging Travel Case.

The iO Series 10 is the ultimate premium model. The handle itself has the exact same features as the Series 9—a Full Colour Interactive Display, 7 cleaning modes, and 3D Position Detection.

This base provides real-time guidance (coverage, time, and pressure) using integrated LED light signals, meaning you can get full A.I.-powered coaching without needing to open your smartphone app. It also features a digital clock and timer directly on the charger base.

In summary, both offer the best cleaning technology and tracking available from Oral-B. The iO Series 9 requires you to check the app on your smartphone for the most detailed feedback. The iO Series 10 offers the same functionality, but the upgrade is the iO Sense Smart Charger that moves the personalized guidance off the phone and onto the charging base for maximum convenience.

Here are the key similarities shared by the Oral-B iO Series 5, 6, 7, 8, 9, and 10:

---

Core Technology & Cleaning Action

• iO Magnetic Drive System: All models use the same breakthrough Linear Magnetic Drive system. This frictionless motor is the “heart” of the brush and is responsible for transferring energy directly to the bristle tips.
• Oscillation-Rotation with Micro-Vibrations: They all utilize the combination of Oral-B’s dentist-inspired round brush head oscillating and rotating, along with gentle micro-vibrations. This delivers the same fundamental, powerful, yet gentle clean across the entire line.
• Plaque Removal: All models are clinically proven to remove 100% more plaque and achieve significantly healthier gums compared to a manual toothbrush.

Safety & Timing

• Smart Pressure Sensor: Every model from the iO 5 through 10 features the Smart Visible Pressure Sensor (the multi-colored light ring). It glows red when you press too hard, white when you press too light, and green when the pressure is just right, protecting your gums and enamel.
• 2-Minute Quadrant Timer: All models have a built-in timer that ensures you brush for the dental professional-recommended two minutes. They also pulsate every 30 seconds to alert you to move to the next quadrant of your mouth.

Connectivity & App Integration

• Bluetooth Connectivity: All models are Bluetooth-enabled and connect to the Oral-B App.
• A.I. Brushing Recognition: Every single model uses Artificial Intelligence to track your brushing and provides real-time coaching and post-session feedback via the app.
• Brush Head Compatibility: All models use the same specific line of Oral-B iO Series Replacement Brush Heads.

In essence, you get the same powerful, magnetic cleaning performance and gum-protecting pressure sensor regardless of which iO model you choose. The differences simply involve increasing the complexity of the display, the number of cleaning modes, and the convenience of charging/tracking.
