The Oral-B iO Series 6 is a premium electric toothbrush designed to optimize daily oral hygiene through advanced features and a sleek, modern build. The Oral-B iO Series 6 (model number: iO6, Type 3753) was released in 2020 and is part of Oral-B’s iO lineup, known for combining oscillating-rotating technology with micro-vibrations for a thorough and gentle clean. This toothbrush is compatible with Oral-B’s iO-specific replacement brush heads and can connect via Bluetooth to the Oral-B app for real-time brushing feedback.

The toothbrush features a black or white plastic handle with a circular interactive OLED display, which allows users to switch between brushing modes, track brushing time, and receive smiley-face feedback after brushing. It includes five smart brushing modes: Daily Clean, Whitening, Gum Care, Sensitive, and Intense. A built-in pressure sensor provides alerts to prevent excessive brushing force. The Oral-B iO Series 6 also comes with a magnetic charging base and a travel case for portability.

Weighing approximately 0.66 pounds (10.6 oz), the toothbrush has a cylindrical, ergonomic shape common among higher-end models from the 2020s. It is powered by a rechargeable lithium-ion battery that lasts up to two weeks per full charge. The brush head attaches magnetically and vibrates smoothly without harsh mechanical noise, contributing to its premium feel.

This model fits into the broader evolution of Oral-B electric toothbrushes, which shifted toward smart features and more intuitive feedback in the late 2010s. No known recalls or manufacturer defects have been widely reported for the iO6. However, some users have noted that the OLED display may become unresponsive after prolonged use or water exposure, though these incidents are relatively rare.

Other models in the iO series include the iO5, iO7, iO8, and iO9, with each tier offering incremental upgrades in features such as 3D tracking, additional brushing modes, or more premium finishes. The iO6 was succeeded by newer models like the iO10, which integrates an advanced smart charger that provides live brushing feedback without needing the app.

Overall, the iO Series 6 was praised for its blend of modern design, gentle yet effective cleaning performance, and accessible smart features, making it a reliable mid-range choice in Oral-B’s iO lineup.

The Oral-B iO Series 6 has a slim, cylindrical body with a slightly flattened front face housing the control buttons and display. The circular brush head attaches at the top, while the power and mode buttons are located just below the interactive OLED screen on the front. The charging contact and type number (3753) are found on the bottom of the handle, printed on a sticker.

To positively identify the device, look for the circular OLED display and the magnetic charging ring near the base. The toothbrush is only compatible with iO series brush heads and features a soft-touch matte finish. The device is available in black, white, and pink color variants.
