Oral-B iO Series 8 Electric Toothbrush, Black Onyx pairs a round brush head with magnetic drive technology, micro-vibrations, and a color display. The US model lists six smart brushing modes and a price of $249.99 as of 09/23/2026.

What Comes in the Box

The Black Onyx package includes one rechargeable handle, three Oral-B iO Ultimate Clean replacement brush heads, one premium travel case, and one magnetic charger. Oral-B lists a two-year warranty for the toothbrush, beginning on the purchase date.

The handle connects to the Oral-B app through Bluetooth, while the interactive display shows brushing time and battery information. The brush is compatible only with Oral-B iO replacement heads, so standard Oral-B Pro heads do not fit this model.

Modes Charging and Guidance

The six modes are Daily Clean, Sensitive, Whiten, Gum Care, Intense, and Super Sensitive. A pressure sensor signals brushing pressure as too hard, too soft, or just right, giving the handle a broader feedback range than a basic pressure alert.

Independent testing reports three-hour charging through the magnetic puck and a maximum battery life of two weeks, with shorter real-world endurance in testing. The same review identifies the iO8's real-time app feedback as useful for tracking coverage, while noting that the more expensive iO9 adds tracking across 16 zones.

How It Compares

The iO8 sits below Oral-B's iO9 and iO10 in the lineup. The iO9 offers 16-zone tooth tracking, while the iO8 uses six-zone guidance; the iO8 therefore provides connected coaching without the top model's more detailed coverage map.

Compared with a manual toothbrush, the iO8 adds a two-minute timer, 30-second interval alerts, pressure feedback, Bluetooth connectivity, and powered oscillating movement with micro-vibrations. Those features add control, but the $249.99 price places it in the premium rechargeable toothbrush category.

Best Fit for Connected Brushing

The Oral-B iO Series 8 is suited to users who want a visible timer, several cleaning modes, pressure guidance, and app-based coverage tracking in one handle. Its main limits are the dedicated iO replacement heads, the magnetic charger's three-hour charging time, and a price above simpler electric toothbrushes.
