Oral-B iO Series 9 Rechargeable Electric Toothbrush, Black Onyx pairs a round brush head with magnetic drive technology, a color display, and app-connected brushing guidance. The handle and brush head weigh 4.4 oz, while the handle alone weighs 4.1 oz.

Seven Modes and Smart Tracking

The brush offers 7 brushing modes: Daily Clean, Whiten, Gum Care, Sensitive, Super Sensitive, Intense, and Tongue Clean. A color display shows brushing mode, charging progress, and the built-in 2-minute timer.

Bluetooth connects the handle to the Oral-B app. AI Brushing Recognition and 3D Teeth Tracking map tooth surfaces across the front, top, and back, while the Smart Pressure Sensor signals brushing pressure through the handle's light system.

Travel Package and Charging

The US package includes 4 Oral-B iO Ultimate Clean replacement brush heads, a Power2Go charging travel case, and a charger. The brush is compatible only with Oral-B iO replacement brush heads.

The magnetic charger reaches a full charge in about 3 hours. Oral-B lists a 2-year warranty for its rechargeable toothbrushes, and Target identifies the model with the ADA Seal of Acceptance.

Price and Category Context

Oral-B lists the Black Onyx model at $329.99 as of 09/23/2026. Target listed an iO Series 9 package with 4 brush heads at $264.99 on 09/22/2026, placing the model in the premium electric toothbrush segment.

Compared with less expensive iO models, the Series 9 adds the full 7-mode set, the color display, AI recognition, 3D Teeth Tracking, and a charging travel case. Its use case is strongest for people who want app-based coverage guidance and a handle that shows pressure and brushing information directly.

Verdict for App-Guided Brushing

The Oral-B iO Series 9 is a premium electric toothbrush built around connected coaching rather than a minimal timer-and-motor setup. Its 4.4-oz handle-and-brush-head weight, 7 modes, 3-hour magnetic charging, and four included brush heads define the package. The added display and tracking features are less relevant for users seeking a basic rechargeable toothbrush.
