What the iO Series 4 electric toothbrush is

The Oral-B iO Series 4 is a rechargeable electric toothbrush supplied with one brush head, a charger and a travel case. It uses a lithium-ion battery and offers four cleaning modes including Daily Clean, Sensitive, Super-Sensitive and Whitening. A pressure sensor signals when the perfect pressure is applied and a light-ring timer marks the dentist-recommended two minutes.

What to check on your existing setup before ordering

Verify that the bathroom has a power outlet suitable for the supplied charger or plan to charge the handle elsewhere. Confirm that the single included brush head matches your preferred bristle texture and that replacement heads compatible with the iO series are available for future changes. The unit is not intended for children under three years old.

Who this suits and who should look elsewhere

This model suits adults who want app-connected brushing feedback, a pressure sensor for gum protection and a choice of four modes in a white handle. Buyers who need multiple brush heads in the box, a travel case with integrated charging or a model designed for younger children should consider other options.
