Level with the Philips Sonicare DiamondClean Prestige 9900 HX9992/12
The Philips Sonicare DiamondClean Prestige 9900 HX9992/12 and the Oral-B iO Series 10 score the same, so either is a safe pick. The Philips Sonicare DiamondClean Prestige 9900 HX9992/12 goes first because it leaves owners a little happier. The Oral-B iO Series 10 is the newer design.
About the Oral-B iO Series 10
The iO 10 is Oral-B's top iO handle, made in Germany. It stands 24cm tall with a head fitted, measures 2.8cm across and weighs 140g with the head on. It has a button for switching modes, a small display on the handle and a light ring that changes colour when you press too hard. It uses a lithium-ion battery and takes as little as three hours to charge fully.
There are seven modes: Daily Clean, Sensitive, Super Sensitive, Whiten, Gum Care, Intense and Tongue Clean. The Oral-B app lets you reorder or switch off modes. It also tracks which part of the mouth you are brushing and reminds you when to change the head. Oral-B says the brush runs for around two weeks per charge.
The iO Sense charger shows the two-minute timer, 20-second pacing and coverage on its own screen, without the phone. It has no battery of its own and needs to stay plugged in, so it only works with a socket near the sink. It uses a detachable two-pin adapter and is not compatible with the usual Oral-B charging stand. The box also holds a charging travel case, which takes one handle and one head and charges the brush through the same adapter.
Heads are iO-specific and do not fit other Oral-B handles. They come in several styles, including Ultimate Clean and Gentle Care. They cost about twice as much as heads for non-iO Oral-B brushes, according to Electric Teeth.
What owners report about the Oral-B iO Series 10
Owner feedback for this exact model is thin, and what follows comes mostly from reader comments under Electric Teeth's UK write-ups.
The most common complaint is the charger. Owners without a socket near the bathroom sink find the iO Sense stand of little use, and several were surprised that it has no battery and switches off when unplugged. The brush also pairs with only one iO Sense charger, and some owners found it would not connect to the app until the charger was powered.
A few owners lost the 20-second pacing after app updates and got only 30-second pacing. The fix was a setting in the charger's real-time feedback menu, or a full app reset. One owner also found the app would not run on iOS 16. Nobody in those threads reported a battery fault, but long-term UK ownership reports are missing either way.
Who the Oral-B iO Series 10 suits
Buy it if you want timing, coverage and pressure feedback on the charger itself, you have a socket by the sink, and you will use a travel case. Two modes for sensitive gums and a quiet motor suit people who find other brushes harsh.
Look elsewhere if you only want a good clean. The Oral-B iO3 gives you the iO range for less, and the Oral-B Vitality Pro is a proper Oral-B for a budget price. If you want longer battery life, the Ordo Sonic Lite runs for over five weeks. The Philips Sonicare DiamondClean Prestige 9900 HX9992/12 is the nearest smart rival.
Questions about the Oral-B iO Series 10
Does the Oral-B iO Series 10 charger work without a plug socket?
No. The iO Sense charger has no battery and switches off when unplugged, so its display only works while it is connected to the mains.
Do Oral-B iO Series 10 brush heads fit other Oral-B toothbrushes?
No. The brush takes iO-specific heads only. They cost about twice as much as heads for non-iO Oral-B models, according to Electric Teeth.
What is the difference between the Oral-B iO Series 9 and iO Series 10?
The Series 10 adds the iO Sense charger with a display and a charging travel case, and is about 11 dB quieter at close range. GearLab measured a longer battery life on the Series 9, at 38.5 days against 22.5 days for the Series 10.
How long is the warranty on the Oral-B iO Series 10?
Two years as standard, with a third year free if you register the brush online, according to Electric Teeth.
How many modes does the Oral-B iO Series 10 have?
Seven: Daily Clean, Sensitive, Super Sensitive, Whiten, Gum Care, Intense and Tongue Clean. You can reorder or switch off modes in the Oral-B app.

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover electric toothbrushes for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 22 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in October 2026.
