The iO Series represents Oral-B’s newest technology with a magnetic drive motor, quieter operation, and smart features. Prices range from $100 (iO Series 3) to $300+ (iO Series 10). The main differences are number of cleaning modes, display screens, and smart coaching features.

💎 Philips Sonicare Electric Toothbrush Comparisons

Philips Sonicare uses sonic vibration technology rather than Oral-B’s oscillating-rotating action. Sonicare brush heads move side-to-side at 31,000 brush strokes per minute, creating fluid dynamics that clean between teeth and along the gumline without touching.

Sonicare’s lineup is organized into series: DiamondClean (premium, $150-250), ProtectiveClean (mid-range, $60-120), ExpertClean (mid-premium, $120-150), and basic models like the 1100 and 3100 ($30-50). The model numbers (like 4100, 4300, 4500, 4700) indicate feature levels within each series.

One advantage of Sonicare: their brushes tend to have longer battery life (often 2-3 weeks) compared to Oral-B. The trade-off is fewer cleaning modes and higher prices for equivalent features.
