Oral-B iO Series 4 Electric Toothbrush - Four Smart Modes

Oral-B iO Series 4 Electric Toothbrush, Matte Black combines a round brush head, micro-vibrations, and app connectivity in a rechargeable handle. The US package includes a replacement brush head, hard travel case, and charger.

Core Features and Package

The iO Series 4 provides four smart brushing modes: Daily Clean, Whiten, Sensitive, and Super Sensitive. Its pressure sensor helps indicate brushing pressure, while the built-in timer divides a 2-minute session into four 30-second intervals.

The box contains 1 iO Series 4 rechargeable electric toothbrush, 1 Oral-B iO Ultimate Clean replacement brush head, 1 hard travel case, and 1 charger. Oral-B states that the handle is compatible only with iO replacement brush heads, and recommends replacing a brush head every 3 months or sooner when worn.

Price and Warranty

Target lists the white Oral-B iO4 at $99.99 as of 09/22/2026. The retailer identifies the product as rechargeable and lists 1 lithium battery, the charger base, travel case, replacement brush head, and a 2-year limited warranty.

The iO Series 4 sits below Oral-B's higher-numbered iO models in the lineup. Compared with a basic manual toothbrush, it adds four modes, a pressure sensor, rechargeable power, and Bluetooth connectivity, but it also requires iO-specific replacement heads.

Best Fit for Daily Brushing

The model suits users who want guided brushing features without moving to Oral-B's most advanced iO handles. The 2-minute timer and pressure feedback address brushing duration and force, while the travel case supports storage away from home.

The main limitation is the accessory ecosystem. Only Oral-B iO replacement heads fit the handle, so existing non-iO Oral-B heads cannot be used. The package also contains one replacement head, making future head purchases part of ongoing ownership.

Product Placement and Verdict

With four modes, a rechargeable battery, Bluetooth, a pressure sensor, and a $99.99 US retail price, the Oral-B iO Series 4 is a midrange electric toothbrush rather than a basic battery-powered brush. It is best suited to users who value a timer, pressure guidance, and app-connected tracking while accepting iO-specific replacement heads.
