Oral-B announced the iO Series 6 during its presentation at MWC on 28 June.

The iO range was launched in 2020 and represented a huge redesign for Oral-B electric toothbrushes, with a new brush head and fresh features, including an OLED screen that provides the user with brushing feedback and settings information.

But the biggest change is to the way the brush performs. Thanks to the frictionless linear magnetic drive that powers the brush head, the iO cleans with micro-vibrations as well as Oral-B’s traditional oscillation. Brush head redesign

And it's this new design and new cleaning performance that you can get at a (somewhat) more budget-friendly price. 

There are currently four models in the iO range: the iO Series 6, the 7, 8 and 9.

When will the iO Series 6 be available to buy?

The Oral-B iO6 is already available to buy in the US from Target. The UK launch date has now been scheduled for 1 November. It'll be stocked by Boots and we also expect to see it for sale on Amazon. 

How much will the Oral B iO Series 6 cost?

In the US, the iO6 is priced at $149.99. In the UK, the launch price will be £300.

So, why the huge difference in prices? Well, first off, the MWC announcement made it clear that the prices would be set by individual countries. But in some markets, such as the UK, an electric toothbrush is given a recommended retail price, which often drops by half to two-thirds after a few months – or even just a few weeks – of being on sale.

Currently in the UK, the Series 7 has an RRP of £400, the Series 8 an RRP of £450 and the Series 9 an RRP of £500. However, these brushes will regularly drop to a third of their RRP for various sales events and holidays.

For example, at the time of writing, you can buy the Oral-B iO Series 8 from Boots in the UK for £160 (somewhat over a third of the RRP). At some stage, this price will jump back up to £400 and the iO7 or iO9 will go on sale.

So, although the iO Series 6 will launch with an RRP of £300, we’d imagine that it will become available for around £100 before too long – although only for limited periods.

In the US, the iO7 is available from BestBuy for $149.99, although the price at Bed, Bath & Beyond comes close: it's $154.39. 

The iO8 currently costs $199.99, also from Bed, Bath & Beyond, but if you're a Beyond+ member, you can get it for $159.99. The iO9 is widely available for $299.99.

What features will the iO Series 6 have?

The Series 6 has fewer features than the other iO Series brushes, although its feature set is extremely similar to the iO7.
