They share a motion family, so most of this page is about features and the bill. Specs are researched from manufacturer pages and named 2026 reviews. Where a number was not published, the cell says n/a. Nothing here is a personal bench log. The method is on how we compare.
How Do They Clean?
Both are oscillating-rotating brushes, so the feel is close. The differences are in features and the bill.
Oscillating-rotating, About 10,500 oscillations and 48,000 pulsations per minute. Last premium of the pre-iO 3D line. Position detection, more modes, cheap classic heads.
Oscillating-rotating, Oral-B does not publish a strokes-per-minute figure for iO. Magnetic iO flagship. Smart Adapt changes intensity from pressure. iO Sense charger coaches without the phone.
A round oscillating head is a tooth-by-tooth scrub. A sonic head is a sweep, and the fluid it throws is part of the clean. A jet or a water flosser is a third job. Do not score those as if they were the same machine.
Which Is Better For Sensitive Gums?
Neither has a clear edge here. Compare the gentle modes below.
Sensitive mode and a visible ring.
Super Sensitive plus Smart Adapt.
Dentists who talk about recession in public usually point at a sonic brush before a round oscillating one, because the sweep feels less sharp on exposed roots. That is a feel call, not a license to skip the pressure sensor. If a brush has no sensor, technique is the whole safety system.
Which Is Better With Braces?
Neither has a braces advantage on paper. Read each note below.
Round head, app map, cheap replacement heads. A strong braces math pick.
Best Oral-B coverage coach in this set, still a round head.
Round heads reach the tooth face around a bracket more easily for a lot of people. Long sonic heads cover more enamel per second and bump the wire more often. A built-in flosser helps the gumline under the wire, which a brush alone does not. None of these replace the conversation with your orthodontist. Ask before you aim a jet at hardware.
Which Stops You Brushing Too Hard?
Both warn you when you press too hard. How they warn you is the difference.
SmartRing lights red when you press too hard and also paces the timer. Motor slows, pulsations stop.
3-color ring plus Smart Adapt, which Oral-B says adjusts up to 10 times a second.
A hidden sensor that only cuts the pulsations is easy to miss. A light ring you can see in a mirror is the one people actually change behavior for. Adaptive systems that turn the motor down are a step past a warning. No sensor at all means the brush will happily let you scrub a groove into the gum.
Which Battery Lasts Longer?
Neither has a verified battery advantage.
14 days. Lithium-ion, about 14 days, some tests to 16. Charge around 12 hours.
14 days. About 2 weeks. The iO Sense charger is the product. Real-time time, coverage, and pressure on the charger, 6 zones, phone optional during the brush.
Runtime assumes two minutes, twice a day, on a gentler mode. Whitening modes, radios, and jets spend it faster. A NiMH pack that wants an overnight charge is a different product from a lithium handle that is full before dinner.
Do The Replacement Heads Cross Over?
Yes. Both take iO heads, so a drawer of refills survives the swap.
Standard Oral-B round heads. Not iO. This is the quiet advantage. About $5 a head. Classic Oral-B heads, not iO. Four heads a year stay near $20.
Round iO head only. About $8 a head. Same iO heads as the $65 Series 2. You are paying for the charger and the software.
The American Dental Association tells people to change a brush about every three months, or sooner if the bristles splay. Four heads a year is the math we use. A subscription only helps if you were going to buy that brand's head anyway.
Which Has An App, Timer Or Screen?
Both have an app.
App: the Oral-B app. Timer: 2-minute timer, 30-second pacer, app position detection. Handle screen: no.
App: the Oral-B app. Timer: iO Sense charger uses 20-second sextant pacing. The handle still has a 2-minute session.. Handle screen: yes.
Apps coach coverage. They do not clean teeth. If you will not put a phone on the sink, a brush that needs the phone for its headline feature is the wrong spend. A timer and a quadrant pacer are the features that change a two-minute session. Quadpacer is Philips's name for that 30-second buzz. Oral-B does the same job without the trademark.
Which Costs Less Over Three Years?
The Oral-B Genius X costs less over three years: $210 against $396.
Handle $150 plus about $20 a year in heads: $210 over three years. Warranty 2 years.
Handle $300 plus about $32 a year in heads: $396 over three years. Warranty 2 years.
Street handle prices here are typical US prices as of October 2026, not a live checkout. A subscription that unlocks a warranty is a cost, not a gift. Read the cancel terms before you count the years.
Are They ADA Seal Accepted?
Both carry a verified ADA Seal.
Accepted, per the manufacturer or a current product page.
Accepted, per the manufacturer or a current product page.
The Seal means the American Dental Association accepted a safety and efficacy file for that product. It is not a ranking, and a missing seal is not a verdict that the brush fails. Some brands never file. Neither brush is a treatment for gum disease. Bleeding that continues after a week of gentle brushing is a dentist appointment, not a mode setting.
Which One Should You Buy?
For most people in this pair, buy the Oral-B Genius X. Buy the Oral-B iO Series 10 if this sounds like you: coaching on the charger if you will not prop a phone on a wet sink.
Choose it for: app coaching without iO head prices.
Choose it for: coaching on the charger if you will not prop a phone on a wet sink.
Editorial rank on this site puts the Oral-B Genius X ahead. That rank is a buying call. It is not a claim that the other brush cleans worse in a lab we did not run.
What Goes Wrong With Each?
- Previous-generation drive. Louder, and Oral-B is no longer designing around it.
- 12-hour charge versus about 3 hours on iO magnetic chargers
- Street price swings hard. A $200 list and an $80 sale are both real. Compare the tag in front of you with an iO Series 5.
- Street prices near $300 to $400. The brush does not clean a cavity the Series 3 missed.
- iO Sense charger is another object. Travel without it and you lose the feature you paid for.
- No camera and no floss. That is the Dyson conversation, not this one.

How Do These Two Sit In The Wider Rankings?
Sitewide, the brush we point at first is the Oral-B iO Series 3, with the Philips Sonicare 4100 next to it. This pair is one cell in that table. See the best picks by need if you have not picked a motion yet, or open the Brush Finder if budget and gums are the whole question.
External reading that matches a claim on this page: the ADA toothbrush overview for the three-month head swap and the Seal, Oral-B's iO guide for series features, and Dyson's CameraJet page for the 2026 jet brush. A brand page is a spec source, not a referee.
