The Oral-B iO series has revolutionized electric toothbrushes, introducing a range of models from the entry-level iO Series 2 up to the premium iO Series 10. Launched initially with the Series 7, 8, and 9 in 2020, the iO lineup now boasts nine distinct brushes, each offering a unique set of features and price points. If you’re in the market for an upgrade, you’re likely wondering which model best fits your needs and budget. Specifically, you might be asking: how does the Oral-B iO3 compare to the other models in the series?
This comprehensive guide breaks down the key differences between all Oral-B iO models, with a special focus on the iO3, to help you make an informed decision. We’ll explore what features are standard across the range, where the models diverge, and ultimately, whether the iO3 strikes the right balance of features and value for you.
What Features Are Consistent Across the iO Series?
Despite the varying price tags and feature sets, all Oral-B iO toothbrushes share a core set of technologies and benefits. Understanding these commonalities is crucial before diving into the differences, especially when considering the Oral-B iO3 compare question. Every iO model (excluding the iO2 in some instances) offers:
- Two-Minute Timer: Ensures dentist-recommended brushing time.
- 30-Second QuadPacer (or Sextant Pacer on iO10): Guides you to brush each quadrant or sextant of your mouth evenly.
- Smart Visible Pressure Sensor: A key feature for gum health, this sensor visually indicates brushing pressure:
- Red Light: Brushing too hard.
- Green Light: Correct pressure.
- White Light: Insufficient pressure.
- Long-Lasting Lithium-Ion Battery: Provides 14+ days of battery life on a single charge.
- Bluetooth Connectivity (Except iO2 & iO3): Connects to smartphones for app-based tracking and personalized feedback (note: iO3 lacks this).
- Quiet Magnetic Drive System: Offers a smoother, quieter brushing experience compared to traditional electric toothbrushes (iO2 uses a linear pulse drive).
- Oscillating-Rotating Cleaning Action with Micro-Vibrations: Provides superior plaque removal.
- iO-Specific Brush Heads: Designed for optimal performance with iO technology.
- Sleek, Minimalist Design: A modern aesthetic that sets them apart from older Oral-B models.
Price and Value: Where Does the iO3 Fit?
The iO series caters to a wide range of budgets. The iO2 is the most affordable entry point, while the iO10 sits at the premium end. The price difference between the base and top models can be significant, raising questions about value for money, particularly when we consider the Oral-B iO3 compare aspect.
The iO3 is positioned as an upgrade from the iO2, offering improved features without the premium price of the higher-end models. While the iO10 might boast the most advanced technology, its high cost ($320 RRP) makes it a less accessible option for many.
The long-term cost of ownership is also important. All iO brushes use the same iO brush heads, meaning the ongoing expense is consistent across the range. Therefore, the initial purchase price of the handle heavily influences the overall value proposition.
Model | Retail Price | Typical Selling Price | Approximate 3-Year Cost |
---|---|---|---|
Oral-B iO Series 2 (iO2) | $59.97 | $59.97 | $192 |
Oral-B iO Series 3 (iO3) | $80 | $64 | $196 |
Oral-B iO Series 4 (iO4) | $100 | $80 | $212 |
Oral-B iO Series 5 (iO5) | $120 | $96 | $228 |
Oral-B iO Series 6 (iO6) | $150 | $120 | $252 |
Oral-B iO Series 7 (iO7) | $200 | $160 | $280 |
Oral-B iO Series 8 (iO8) | $250 | $200 | $308 |
Oral-B iO Series 9 (iO9) | $300 | $240 | $335 |
Oral-B iO Series 10 (iO10) | $400 | $320 | $416 |










Note: Prices are approximate and may vary by retailer.
The iO3 offers a small step up in price from the iO2 but includes a more refined pressure sensor. For those seeking a balance of features and affordability, the iO6 is often considered the sweet spot, offering a display and more features at a mid-range price. While the iO10 is technologically advanced, its premium cost may not be justified for all users.
Display Differences: iO3 vs. Models With Screens
Five out of the nine iO models feature a display built into the brush handle. Three of these are color displays, while two are black and white. The iO3, however, does not include a display.
While displays add a touch of sophistication and functionality, they aren’t essential for effective brushing. Displays allow for customization like language settings, smart ring color changes, and brush resets. The primary benefit is easier mode selection and mode indication.
Model | Display | Display Additional Information |
---|---|---|
Oral-B iO Series 2 (iO2) | – | – |
Oral-B iO Series 3 (iO3) | – | – |
Oral-B iO Series 4 (iO4) | – | – |
Oral-B iO Series 5 (iO5) | – | – |
Oral-B iO Series 6 (iO6) | Yes | Black & white, non-touchscreen |
Oral-B iO Series 7 (iO7) | Yes | Black & white, non-touchscreen |
Oral-B iO Series 8 (iO8) | Yes | Color, non-touchscreen |
Oral-B iO Series 9 (iO9) | Yes | Color, non-touchscreen |
Oral-B iO Series 10 (iO10) | Yes | Color, non-touchscreen |
For users considering the Oral-B iO3 compare options, the absence of a display might be a deciding factor. If you value visual feedback directly on the brush handle for mode selection and settings, you’ll need to consider models iO6 and above.
Cleaning Modes: Are More Modes Necessary?
The iO series offers a range of cleaning modes, from 2 to 7 modes depending on the model. The iO3 typically comes with 3 modes: Daily Clean, Sensitive, and Whitening. Higher-end models add modes like Gum Care, Deep Clean, Tongue Cleaning, and Intense Clean.
However, the practical benefit of having numerous cleaning modes is debatable. For most users, the Daily Clean mode is sufficient for everyday oral hygiene. A Sensitive mode is a valuable addition for those with sensitive gums or new electric toothbrush users.
The different modes primarily vary in motor power and bristle oscillation, resulting in slightly different brushing patterns. All modes are timed for 2 minutes, except Tongue Clean, which is 30 seconds.
Model | Number of Cleaning Modes | Clean | Sensitive | Gum | White | Deep Clean | Tongue | Other Modes |
---|---|---|---|---|---|---|---|---|
Oral-B iO Series 2 (iO2) | 3 | Yes | Yes | – | – | – | – | Super Sensitive |
Oral-B iO Series 3 (iO3) | 3 | Yes | Yes | – | Yes | – | – | – |
Oral-B iO Series 4 (iO4) | 4 | Yes | Yes | – | Yes | – | – | Super Sensitive |
Oral-B iO Series 5 (iO5) | 5 | Yes | Yes | – | Yes | – | – | Super Sensitive, Intense |
Oral-B iO Series 6 (iO6) | 5 | Yes | Yes | Yes | Yes | – | – | Intense |
Oral-B iO Series 7 (iO7) | 5 | Yes | Yes | Yes | Yes | – | – | Intense |
Oral-B iO Series 8 (iO8) | 6 | Yes | Yes | Yes | Yes | Yes | – | Super Sensitive, Intense |
Oral-B iO Series 9 (iO9) | 7 | Yes | Yes | Yes | Yes | Yes | Yes | Super Sensitive, Intense |
Oral-B iO Series 10 (iO10) | 7 | Yes | Yes | Yes | Yes | Yes | Yes | Super Sensitive, Intense |
When considering the Oral-B iO3 compare to models with more modes, think about your actual needs. If you’re satisfied with basic cleaning and sensitive options, the iO3’s mode selection will likely suffice.
Mode Indication: Knowing Which Mode You’re Using
The iO2, iO3, and iO4 lack direct mode indication on the handle. The iO5 uses backlit icons, while Series 6 and above display icons with text on their screens. Models with Bluetooth connectivity (excluding iO2 and iO3) show the active mode within the app. On iO2, iO3, and iO4, mode changes are only possible after turning the brush on.
For Oral-B iO3 compare considerations, the lack of on-handle mode indication is a minor drawback. While higher models offer visual confirmation, most users likely stick to one or two preferred modes, minimizing the need for frequent mode switching.
Real-Time Tracking: App Connectivity and Zone Coverage
Real-time tracking, a key smart feature of the iO series, uses the Oral-B app to visualize your brushing technique. However, tracking capabilities vary significantly across models.
The iO2 and iO3 lack Bluetooth connectivity and therefore offer no real-time tracking. The iO4 has Bluetooth but only provides a timer function within the app, without real-time position tracking. iO5 through iO10 offer real-time tracking, but the level of detail differs.
iO5 to iO8 provide 6-zone tracking, while iO9 and iO10 boast comprehensive 16-zone tracking for more granular feedback.

16 Zone vs 6 Zone Tracking: Is More Always Better?

The 16-zone tracking offered by iO9 and iO10 provides a highly detailed map of your mouth, dividing it into:
- Upper Rear Right: Front, biting, and inside surfaces.
- Upper Front: Front and inside surfaces.
- Upper Rear Left: Front, biting, and inside surfaces.
- Lower Rear Right: Front, biting, and inside surfaces.
- Lower Front: Front and inside surfaces.
- Lower Rear Left: Front, biting, and inside surfaces.
In contrast, 6-zone tracking (iO5 to iO8) groups these areas more broadly:
- Upper rear right
- Upper front
- Upper rear left
- Lower rear right
- Lower front
- Lower rear left
While 16-zone tracking offers potentially more precise feedback, the real-world difference for everyday users is debatable. To maximize the benefits of either tracking system, consistent app usage is necessary. The iO10’s iO Sense stand provides 6-zone feedback without the app, offering quick insights but less detail than the app-based 16-zone tracking. Currently, there’s no conclusive long-term data proving the superior benefits of app-based tracking compared to traditional brushing techniques and tools like plaque disclosing tablets.
Brush Head Replacement Reminders: A Helpful Nudge
Replacing brush heads every 3 months is crucial for optimal cleaning and hygiene. All iO models except the iO2 include brush head replacement reminders in the app and on the handle. iO3, iO4, and iO5 use a yellow light on the mode button and handle vibrations for reminders. Display models show notifications on-screen and in the app. While convenient, these reminders are not essential; calendar reminders can serve the same purpose. Their inclusion across most iO models means this feature shouldn’t heavily influence your choice when considering Oral-B iO3 compare options.
Battery Life: Premium Models and Inconsistencies
Oral-B claims “2 weeks+” or “long-lasting” battery life for iO handles. Most models average 17-20 days of use. However, testing reveals inconsistencies, with iO9 sometimes lasting only 12 days, while iO2 can reach up to 37 days. Battery capacities also vary; iO2 has a 600mAh battery compared to iO3’s 750mAh. The iO2’s different motor and the displays on premium models likely affect battery performance. Displays activating with movement also consume battery power.
Charging Stands: Standard vs. Premium Magnetic
iO2, iO3, iO4, iO5, and iO6 include a standard white Oral-B charger with a 2-pin 110-130v adapter, taking 12-24 hours for a full charge. iO7, iO8, and iO9 feature a premium magnetic stand in white or black, with a 2-pin 100-240v adapter and ~3-hour recharge time. Only iO7-iO10 are compatible with the magnetic stand. The iO3 comes with the standard charger. While the magnetic stand is visually appealing and faster, the standard charger functions adequately.
Model | Charging Time | Charging Stand Included | Voltage Support | Battery & Charging Additional Information |
---|---|---|---|---|
Oral-B iO Series 2 (iO2) | Up to 24 hours | Yes | 110-130v | – |
Oral-B iO Series 3 (iO3) | Up to 16 hours | Yes | 110-130v | – |
Oral-B iO Series 4 (iO4) | Up to 16 hours | Yes | 110-130v | – |
Oral-B iO Series 5 (iO5) | Up to 16 hours | Yes | 110-130v | – |
Oral-B iO Series 6 (iO6) | Up to 12 hours | Yes | 110-130v | – |
Oral-B iO Series 7 (iO7) | ~3 hours | Yes | 100-240v | Magnetic charging stand |
Oral-B iO Series 8 (iO8) | ~3 hours | Yes | 100-240v | Magnetic charging stand |
Oral-B iO Series 9 (iO9) | ~3 hours | Yes | 100-240v | Magnetic charging stand |
Oral-B iO Series 10 (iO10) | ~3 hours | Yes | 100-240v | Magnetic iO Sense charging stand |
The iO10’s Unique iO Sense Stand
The iO10 includes an iO Sense charging stand, which, in addition to magnetic charging, features LEDs and a clock to provide real-time feedback on brushing coverage without needing the app. This stand offers 6-zone feedback, aiming to encourage thorough brushing. However, this feature significantly increases the iO10’s price, making it potentially unjustifiable compared to the iO9, which lacks only this stand feature.
Battery Feedback: Display vs. LED Indicator
Battery charge indication varies. Display models show a battery icon and percentage after each use. iO2, iO3, iO4, and iO5 use a white LED in the power button, pulsing red only when charge is below 10%. App-connected models also display battery percentage within the app. The iO3 uses the LED indicator. For detailed battery status, display models offer clearer feedback.
Travel Cases: Charging and Quality Differences
Most iO models include a travel case for handle and brush head protection during travel. iO2 and iO3 standard models often exclude a case, though variants with cases exist. iO9 and iO10 cases can charge the handle using a proprietary power adapter (no battery in the case itself) and hold only one brush head. Cases for iO7, iO8, iO9, and iO10 are generally higher quality, thicker, and more durable. The iO3 may or may not include a travel case depending on the specific package.
