Finding a new electric toothbrush can feel overwhelming given the vast array of technologies and models. The Oral-B iO series, with its magnetic drive technology, raises particular questions: Which model is right for my needs, and what are the precise differences?
This article is here to help. As your Joybuy Product Recommendation Officer, I've compiled the essential information on the Oral-B iO models to provide an objective foundation for your decision. The goal is to clearly present the features and differences of each device.
Choosing a specific model from the Oral-B iO series depends on your personal oral care needs. Here are three key aspects to consider during your selection.
The core feature of the iO series is the magnetic toothbrush. A magnetic drive transfers energy directly and frictionlessly to the bristle tips. This creates gentle micro-vibrations, which produce the signature cleaning experience of the iO models. The number of available brushing modes (e.g., Daily Clean, Sensitive, Gum Care, Whitening) varies by model. Entry-level devices like the Oral-B iO 2 offer basic modes, while more advanced models like the Oral-B iO 10 include up to seven specialised programmes.
Brushing with too much pressure can damage your gums. All Oral-B iO models feature a smart toothbrush with pressure control. A light ring on the handle indicates whether you are applying optimal pressure (green light), too much pressure (red light), or too little pressure (white or another colour, depending on the model). This feature promotes an effective yet gentle clean and is a key factor for long-term gum protection.
Some iO models offer an electric toothbrush with an app that connects to your smartphone via Bluetooth. The app provides real-time feedback on your brushing habits, tracks coverage of each area of your mouth, and saves the data for analysis. Models like the iO 6 use artificial intelligence for position detection, while the iO 10 provides an even more detailed analysis of 16 zones in your mouth with 3D tracking. This is a relevant feature for users who want to use data to optimise their brushing routine. For those who prefer a straightforward experience without an app, the basic models are a suitable alternative. Independent reviews, such as those occasionally conducted by consumer organisations like Germany's Stiftung Warentest, can also serve as a source of information to assess the performance of individual features.
Here is a detailed overview of three selected models from the Oral-B iO series, covering a range of user needs.
Why it stands out: The iO 10 is the flagship model of the series, integrating a coaching function directly into the device with its iO Sense Smart Charger. It provides real-time feedback on brushing time, pressure, and coverage without needing to open the app.
Benefits:
Who it's for: Tech-savvy users who want the most data-driven, guided cleaning experience and are willing to invest in the most advanced technology available.

Why it stands out: The iO 6 offers an excellent balance of advanced features and a more accessible price point. It includes an interactive display and AI-powered position detection via the app.
Benefits:
Who it's for: Users who want to benefit from app connectivity and a display but don't need the full range of features found in the flagship model.

Why it stands out: The iO 2 is the entry-level model into the world of iO magnetic technology. It focuses on core features like the magnetic drive, micro-vibrations, and pressure control. In a test by Stiftung Warentest (issue 12/2025), the model received a score of 2.2 (Good).
Benefits:
Who it's for: Beginners switching from a manual toothbrush or those who want to experience iO technology without needing smart features like a display or app connectivity.

The main differences are the smart features and the number of brushing modes. Higher-end models like the iO 9 or 10 offer a colour display, 3D position detection, and more specialised brushing programmes. More affordable models like the iO 2 focus on the core technology of the magnetic drive and pressure control but omit the display and advanced app functions.
App connectivity can be very useful for users who want to actively improve their brushing habits. The app visualises which areas have been sufficiently cleaned and where you still need to brush. It provides personalised feedback and can thus contribute to a more thorough and consistent clean. However, for users who prefer a simple and straightforward routine, this feature is not essential.
Oral-B recommends replacing the brush head every three months. After this time, the bristles lose their firmness and become less effective at removing plaque. Some iO models with a display or app connectivity will automatically remind the user when it's time for a change.
