Oral-B iO Series 4 Electric Toothbrush, Matte Black brings a round rechargeable handle, a visible pressure sensor, and four cleaning modes to a midrange electric toothbrush. The US model includes one replacement brush head, a hard travel case, and a charger.

Core Features And Contents

The iO Series 4 offers Daily Clean, Sensitive, Super-Sensitive, and Whitening modes, plus a light-ring timer designed around a 2-minute brushing session. Its pressure sensor uses color feedback to indicate brushing pressure, while the included travel case protects the handle during transport.

The official US listing specifies compatibility only with Oral-B iO replacement brush heads. Earlier Oral-B Pro and Genius handles use a different attachment system, so those older heads are not interchangeable with the iO handle.

Price And Warranty

Oral-B lists the Matte Black iO Series 4 at $99.99 (as of 09/23/2026). Target also lists the white iO Series 4 at $99.99, placing the model in the same price range as the manufacturer's US listing.

The US warranty runs for 2 years from the purchase date. The included package contents are one iO Series 4 rechargeable toothbrush, one iO Ultimate Clean replacement brush head, one hard travel case, and one charger.

Position In The iO Range

Oral-B positions the Series 4 above the iO Series 3 with four cleaning modes and a travel case, while the lower-priced iO Series 2 is listed at $49.99 by Target. The Series 4 therefore adds controls and accessories without moving into the higher-priced iO models.

For users moving from a manual brush, the pressure feedback, 2-minute timer, and round iO head provide direct brushing guidance. The main limit is the proprietary iO head connection, which excludes older Oral-B refill systems.

Verdict For Daily Brushing

The Oral-B iO Series 4 is a rechargeable personal-care device for users who want four modes, pressure feedback, Bluetooth app compatibility, and a travel case at a $99.99 US list price. Its strongest practical distinction is the combination of guided brushing controls and the iO-only refill system.
