The Oral-B iO Series 9 electric toothbrush brings data-driven technology to oral care, offering real-time tracking, pressure feedback, and multiple cleaning modes. Priced at Rs 16,499 in India, it promises to improve brushing habits but comes with a hefty price tag.
Design and Build
The iO Series 9 is Oral-B's flagship toothbrush, featuring a redesigned magnetic motor that delivers oscillating-rotating motion with micro-vibrations. The brush feels quieter and more controlled than older models, making the two-minute brushing session comfortable. The handle includes a color display that shows brushing modes, battery percentage, and a pressure ring that lights up green (correct pressure), red (too hard), or white (too light).
Performance and Smart Features
The iO9 offers seven cleaning modes: Daily Clean, Sensitive, Whiten, Gum Care, Intense, Super Sensitive, and Tongue Clean. The pressure sensor is a standout feature, helping users avoid aggressive brushing. The brush connects via Bluetooth to the Oral-B app, which provides real-time position tracking of 16 mouth zones. While the tracking is innovative, it occasionally lags or misidentifies zones, and the app may not be for everyone.
Battery and Charging
Battery life lasts about 10-11 days on a single charge, close to the rated two weeks. The magnetic charger takes three hours for a full charge. A charging travel case is included, but there is no USB charging option, requiring the proprietary charger during travel.
Pros and Cons
- Excellent cleaning performance with effective plaque removal along the gum line.
- Pressure sensor helps build proper brushing habits.
- Smart tracking offers detailed coverage maps and brushing history.
- Color display shows battery and mode clearly.
- High price at Rs 16,499 (often available for around Rs 10,000 on Amazon).
- Proprietary brush heads are expensive to replace.
- No USB charging limits travel convenience.
- App dependency may not suit everyone.
Verdict
The Oral-B iO Series 9 is best for tech-savvy users who want data-driven feedback to improve their brushing technique. It is not for budget-conscious buyers or those who prefer simplicity. While it does not replace a dentist, it helps maintain oral hygiene and may reduce dental visits. Overall, it is a niche product that delivers on its promise of smart oral care.
