The Oral-B iO Series 2 and Series 3 differ primarily in interactive feedback, battery endurance, and price.

Core Similarities: Oral-B iO Series 2 and Series 3
Despite their differences in motor and charging technology, the Oral-B iO Series 2 and Series 3 share the essential features that define the highly-rated iO electric toothbrush line, ensuring a superior cleaning experience from either model:
- iO Magnetic Technology: Both brushes feature the core iO technology, which uses powerful, yet gentle micro-vibrations combined with Oral-B’s dentist-inspired round brush head design. This magnetic interaction is responsible for delivering the advanced, 100% more plaque removal compared to a regular manual toothbrush.
- Plaque Removal Effectiveness: Both are designed to be Tough on Plaque, Gentle on Gums and are guaranteed to remove 100% more plaque versus a regular manual toothbrush. (The Series 3boasts a clinical claim of 400% more plaque removal along the gumline, but the 100% figure is the shared standard claim.)
- Gum Protection: Both include a Pressure Sensor to protect your gums. The brush slows down the speed when too much force is detected, ensuring a safe and effective clean.
- Built-in Timer: Both models feature the necessary 2-Minute Timer that signals after two minutes (the dentist-recommended brushing time). They also both include the quadrant timer that breaks the two minutes into four 30-second intervals to guide you to clean each section of your mouth evenly.
- Brush Head Compatibility: Both the iO Series 2 and iO Series 3 are compatible with all Oral-B iO Replacement Brush Heads (Ultimate Clean, Gentle Care, Radiant White, Specialized Clean).
- Power Source: Both use a long-lasting Lithium-ion battery and are rechargeable.
In essence, both toothbrushes deliver the same fundamental, high-performance clean that the iO series is known for.
