Product Summary
For 2025, the Oral-B iO3 has officially taken the top spot as our best value recommendation. It brings the premium magnetic iO technology—previously only found in brushes over £150—down to a much more accessible price point. The cleaning performance is a significant step up from older models.
While the Oral-B Pro 3 (our previous value pick) remains an excellent budget-friendly brush, the superior cleaning action and features of the iO3 make it the clear winner for value this year.
It’s only a little more expensive than the Pro 3 but offers the extra pulsating technology that is usually found in the more expensive IO models.
If the Pro 3 is priced around £40 and the IO8 around £100, this new IO3 model sits at approximately £60. Given this price range, the IO3 is likely worth the upgrade.
The IO3 does have some drawbacks. It only has 3 cleaning modes and lacks the color display screen of the IO8. However, this simpler design has the advantage of prolonged battery life.
If you want the latest cleaning technology at the lowest price, the IO3 is the one for you.
