Last updated 6 November 2026. Written by the Clean Smile Home team. We sell both of these brushes, so we've tried to be fair to each. We don't run lab tests ourselves: test figures come from the independent reviewers named in the sources at the end, and specifications come from Oral-B and the reviewers.
The short answer
The Oral-B iO2 is the nicer brush and the Vitality Pro is the better bargain. The iO2 adds a pressure sensor, a smoother, gentler magnetic drive, a battery that lasts weeks rather than days, and a travel case. Independent testers found little or no difference in how clean either gets your teeth, and the Vitality Pro's heads cost half as much.
So the real question isn't which cleans better. It's whether a pressure warning, a month between charges and a more refined feel are worth about £12 more up front and roughly £35 more over three years. For a lot of people they are. For a lot of others, the Vitality Pro does the job for £23.

Who should buy which: the quick version
- You want the cheapest decent electric toothbrush: Vitality Pro. Tech Advisor called it the best cheap electric toothbrush you can buy.
- You know you brush too hard: iO2, as it has a pressure light and the Vitality Pro has none. If pressure is your main worry, also look at the iO3.
- You hate charging things or you travel a lot: iO2, by a mile.
- You already have a drawer of Oral-B heads: Vitality Pro. They'll fit. They won't fit an iO2.
- You're buying for a teenager or a student: Vitality Pro if it might get lost or dropped, iO2 if they'll never remember to charge it.
- You're buying for two: two Vitality Pros are cheapest. The iO2 Duo is the value way to get two iO handles.
- You want it to feel like a step up from a cheap brush: iO2. The magnetic drive feels smoother and more refined in the mouth.
What the Vitality Pro and iO2 have in common
Both are rechargeable Oral-B brushes with a small round head, which is Oral-B's signature design. The head cups each tooth and moves back and forth, rather than sweeping side to side like a sonic brush. If you're not sure which style suits you, our guide to sonic vs oscillating toothbrushes explains the difference.
Both have a two-minute timer that nudges you every 30 seconds to move to the next quarter of your mouth. That timer is the single most useful thing an electric toothbrush does. Most people brush for well under two minutes without one.
Both have three modes, two of them gentle. Neither has a screen, Bluetooth or an app. Both charge on a stand with a UK 2-pin plug designed for bathroom shaver sockets, so you'll need an adapter for a normal 3-pin socket. We explain why in why electric toothbrushes have a 2-pin plug. Both come with a two-year manufacturer's warranty.
And, most importantly, both clean well. More on that next.
Difference 1: cleaning power and how it feels
This is where people expect the expensive brush to win clearly. The evidence says it doesn't.
How each brush moves
The Vitality Pro uses Oral-B's older 2D action. The head rotates back and forth, and Electric Teeth gives the figure as about 7,600 oscillations a minute, with none of the extra pulsations found on brushes like the Pro 3. It's a mechanical drive, and you can feel and hear that: Tech Advisor described a slightly rattly note.
The iO2 uses what Oral-B calls a linear magnetic drive. The head still rotates, but the motor is smoother and the feel is softer. Electric Teeth's reviewers describe the iO2 as less aggressive than classic Oral-B brushes, and in its full iO2 review, Electric Teeth also felt its motor was weaker than other iO models. Expert Reviews made a similar point, saying the iO2 lacks the micro-vibrations of the pricier iO brushes.
What the testers found
Electric Teeth has tested the iO2 against Oral-B's classic rotating brushes. In its comparisons with the Pro 1 and the Pro 3, both classic brushes and the iO2 scored full marks for how well they clean, and in its iO2 review the brush removed all the plaque in a disclosing tablet test. Its conclusion was blunt: the iO2 cleaned just as well as more powerful brushes, but no better than the cheaper classic models.
The Pro 1 and Pro 3 aren't the same as the Vitality Pro. They're a step up, and the Pro 3 adds pulsations. But they share the same basic rotating head, and that's the part that does the cleaning. Tech Advisor, reviewing the Vitality Pro, said an iO brush is more effective but the Vitality is good enough for most people.
Our reading: if you brush for two full minutes with the right technique, you're unlikely to see a difference at the dentist between these two. The iO2 is more pleasant to use. The Vitality Pro is more of a workhorse.
Which feels better?
That's personal. Some people love the strong, buzzy feel of a classic Oral-B and find the iO2 a bit tame. Electric Teeth's reviewers said they preferred the deeper feel of the Pro 1 and Pro 3. Others find classic brushes harsh or ticklish, especially in the first weeks, and prefer the iO's smoothness. If you're coming from a manual brush and your gums are sensitive, the iO2 is easier to get used to.
Difference 2: the pressure sensor
The Vitality Pro has no pressure sensor at all. Both Electric Teeth and Tech Advisor list this as its main weakness.
The iO2 has one, but it's basic. A small light in the power button turns red when you press too hard, and Oral-B says the motor slows down. There's no green light for the right pressure. Reviewers including Expert Reviews and T3 found the light hard to see while brushing, because the front of the handle often faces away from the mirror.
Does it matter? For some people, a lot. Brushing too hard wears enamel near the gum line and can push gums back, which causes sensitivity. Former manual brushers are the worst offenders, because with a manual brush pressure is how you get a clean. With an electric brush, pressing harder just stops the head moving properly.
If you already brush lightly, you won't miss a sensor. If your dentist or hygienist has mentioned gum recession or wear, a pressure sensor is worth paying for, and in that case we'd point you past the iO2 to the iO3, whose light ring shows white, green and red and is much easier to see. Our guide what does a pressure sensor do? goes into this, and our iO2 vs iO3 comparison covers that next step up.
Difference 3: battery life and charging
This is the iO2's biggest win, and it's not close.
| Source | Vitality Pro | iO2 |
|---|---|---|
| Manufacturer figure | 10 days (quoted by Electric Teeth); Tech Advisor quotes a maximum of 8 days | Up to 4 weeks (Oral-B) |
| Electric Teeth | 17 days | 37 days |
| Tech Advisor | Around a week; about 4 days when two people shared it | Not tested |
| Expert Reviews | Not tested | About 53 days at 4 minutes a day |
| T3 | Not tested | 5 to 6 weeks |
Battery tests vary with the mode used, brushing time and how new the battery is, which is why the numbers spread. Whichever figures you trust, the iO2 lasts at least twice as long, and often three or four times as long.
Charging is slow on both. Electric Teeth and Tech Advisor give up to 22 hours for a full charge on the Vitality Pro. Oral-B quotes up to 24 hours for the iO2, though Electric Teeth measured about 18.
The Vitality Pro has another catch: there's no battery light or charging indicator on the handle or the stand. Both reviewers mention this. The only warning that it's running low is the motor slowing down, which can happen halfway through a brush. The practical fix is to keep it on its stand between uses.
The Vitality Pro uses a nickel-metal hydride battery, an older type than the lithium-ion battery in the iO2. That partly explains the gap.
Who cares about this? Anyone who keeps their brush in a cupboard, shares a socket with a shaver, travels for work, or simply forgets. With the iO2 you can go on a fortnight's holiday without the charger. With the Vitality Pro, you'll want to pack it. Our guide to travelling with an electric toothbrush has tips on adapters.
Difference 4: modes
| Mode | Vitality Pro | iO2 |
|---|---|---|
| Daily Clean | Yes | Yes |
| Sensitive | Yes | Yes |
| Sensitive Plus | Yes, the gentlest setting | No |
| Super Sensitive | No | Yes, the gentlest setting |
On paper they're almost identical: one full-power mode and two gentle ones. Neither has a whitening mode.
Neither handle labels its modes, so you have to remember the order. On the Vitality Pro, Electric Teeth found that the brush doesn't remember your last mode. On the iO2, the brush starts in Super Sensitive each time, which Expert Reviews found irritating once you're used to full power. There's a fix: Electric Teeth says holding the iO2's power button for about five seconds lets you change the mode order so Daily Clean comes first.
Most people use Daily Clean almost all the time, so we wouldn't decide on modes.
Difference 5: noise
Electric Teeth measured the Vitality Pro at 73 dB and the iO2 at 72 dB in Daily Clean, dropping to about 64 dB in its gentle modes. In full power, then, there's little between them. The iO2 sounds smoother rather than much quieter. In the gentle modes, it's noticeably quieter, which matters if you brush while others sleep. Tech Advisor called the Vitality Pro fairly quiet, so neither is a problem.
Difference 6: brush heads and running costs
This is the Vitality Pro's biggest win, and it's the thing many iO buyers only notice later.
Heads don't swap
The Vitality Pro takes Oral-B's classic round heads, such as Precision Clean, CrossAction and Sensitive. The iO2 only takes iO heads, which are a different shape and won't fit older handles. Our guide which Oral-B brush head fits my toothbrush? has the full list.
Price per head
At our prices, a 12-pack of Precision Clean heads is £23.91, or about £1.99 a head. The iO Ultimate Clean 8-pack is £31.27, about £3.91 a head, and the 4-pack is £21.41, about £5.35 a head. Electric Teeth's own figures across the market were about £2.50 for a classic head and £6 for an iO head, so the pattern is the same: iO heads cost about twice as much.
The real cost over three years
Here's one person, a new head every three months (12 heads over three years), buying heads in the largest packs we sell.
| Vitality Pro | iO2 | |
|---|---|---|
| Handle | £23.00 | £34.95 with travel case |
| 12 brush heads | £23.91 (one 12-pack) | £46.91 (at the 8-pack rate) |
| Three-year total | £46.91 | £81.86 |
| Cost per month | About £1.30 | About £2.27 |
The difference is £34.95 over three years, or about 97p a month. The Vitality Pro's two included heads give you a spare on top, so in practice it's slightly better than this. Electricity for either brush costs pennies a year and doesn't change the result.
Electric Teeth estimates the Vitality Pro's three-year cost at about £55 using typical market prices, and found the iO2 about £70 dearer than a Pro 1 over the same period. Our numbers are lower because our 12-pack and 8-pack prices are below the per-head figures it used, but the gap points the same way.
For two people
Two Vitality Pros cost £46.00, and two 12-packs of heads cover both of you for three years at £47.82, a total of about £93.82. The iO2 Duo is £55.19 for two handles, and 24 iO heads at the 8-pack rate cost £93.81, a total of about £149.00. For a couple, the Vitality Pro saves about £55 over three years.
Is the iO worth the extra?
Here's how we'd weigh it. For about £12 more today, and about 97p a month over three years, the iO2 gives you four things the Vitality Pro doesn't:
- A pressure warning. Basic and easy to miss, but better than nothing if you brush hard.
- Battery life measured in weeks. Roughly 37 to 53 days in tests against 7 to 17 days.
- A smoother, more refined feel. Softer in the mouth and quieter in its gentle modes.
- A travel case. All three of our single iO2 sets include one.
What it doesn't give you, according to the testers, is cleaner teeth. If those four things matter to you, the iO is worth it. If they don't, you're paying for comfort rather than results.
One more thought. If the pressure sensor is the main reason you're looking at the iO2, the iO3 is the brush that does pressure feedback properly. It costs £59.79 with a travel case. At that point the gap to the Vitality Pro is bigger, but so is the benefit for heavy-handed brushers.
Which is better for your situation?
Switching from a manual toothbrush
Either is a big step up, mainly because of the timer. The iO2 is gentler for the first few weeks and its pressure light helps break the scrubbing habit that manual brushers tend to have. The Vitality Pro is the cheap way to find out whether you like electric brushing at all. If you're unsure, our guide electric or manual toothbrush: what really matters covers the evidence.
Sensitive teeth or gums
Both have two gentle modes. The iO2's smoother drive feels softer, and its pressure light helps you avoid one common cause of sensitivity. We'd lean towards the iO2. If sensitivity is new or getting worse, see your dentist, as it can have causes a toothbrush won't fix.
You brush too hard
Not the Vitality Pro, as it has no sensor. The iO2 helps a bit. The iO3 helps most.
Teenagers and students
The Vitality Pro is the safer bet for anyone likely to drop it, lose it or leave it at a friend's house. If they'll never remember to put it on charge, the iO2's battery makes more sense.
Frequent travellers
iO2. It's the only one of the two you can take on a long trip without the charger, and it comes with a travel case.
Couples and families
Two Vitality Pros are the cheapest setup by about £55 over three years. If you both want the iO feel, the iO2 Duo is cheaper than two single iO2s, and you can share packs of heads.
You already own an older Oral-B
If you have spare classic heads, the Vitality Pro uses them. If your old brush was a Pro 3 with a pressure light, moving to the Vitality Pro would be a step down, and the iO2 or iO3 is the better replacement.
A second brush for work, the gym or a partner's place
Vitality Pro. It's cheap enough to leave somewhere, and battery life matters less if it lives on a stand.
Braces
Ask your orthodontist first. Many recommend an electric brush during treatment. Some prefer a brush with pressure feedback, which would point you to the iO2 or iO3, and some recommend specialist heads, which are easier to find in classic Oral-B fittings.
What the reviewers said
We don't test brushes ourselves, so here's what the independent reviewers concluded, in our own words.
- Electric Teeth scored the Vitality Pro 65 out of 100 (4 stars). It liked the grippy handle, the three modes and the spare head in the box. It marked it down for having no pressure sensor, no battery indicator, no mode labels and no mode memory. It scored the iO2 74, praising its battery life and cleaning but criticising its hard-to-see pressure light and weaker motor compared with other iO brushes.
- Tech Advisor called the Vitality Pro the best cheap electric toothbrush you can buy, praising its price, three modes, fairly quiet motor and brushing performance. Its complaints were the long charge time, no charging light and no pressure sensor. It said iO brushes are more effective but the Vitality is good enough.
- Expert Reviews liked the iO2's battery and gentle, quiet clean, but found the pressure light nearly useless and suggested most people would do better with an iO3 on sale.
- T3 called the iO2 a simple, no-fuss brush that suits people coming from a manual toothbrush, with slow charging and a small pressure light as its main gripes.
Put together: reviewers agree the Vitality Pro is excellent value with obvious missing features, and the iO2 is a pleasant, long-lasting entry to the iO range that doesn't clean better than cheaper classic Oral-Bs.
Getting the best results from either brush
- Don't scrub. Guide the head slowly from tooth to tooth and hold it on each one for a couple of seconds. The motor does the brushing.
- Angle towards the gum line. That's where plaque collects.
- Use the 30-second nudges. Move to the next quarter of your mouth each time.
- Use a pea-sized blob of fluoride toothpaste, spit, don't rinse. That's NHS advice and works with any brush.
- Switch on in your mouth. Otherwise the toothpaste ends up on the mirror.
- Change the head every three months. Sooner if the bristles splay. See how often to change your brush head.
- Clean between your teeth. No toothbrush reaches properly between teeth. Our guide to floss, interdental brushes and water flossers helps you choose.
- Keep the Vitality Pro on its stand. With no battery warning, that's the easiest way to avoid a flat brush mid-clean.

Common problems and how to fix them
"My Vitality Pro died halfway through brushing"
There's no low-battery light, so the first sign is the motor slowing. Keep it on the stand when you're not using it. A full charge can take most of a day, so charge overnight.
"My Vitality Pro battery doesn't last as long as it did"
Rechargeable batteries lose capacity over time. If it fails within two years, it's covered by the manufacturer's warranty.
"My iO2 always starts in the gentlest mode"
That's deliberate. Hold the power button for about five seconds to change the order so Daily Clean comes first.
"I can't see the iO2's pressure light"
A common complaint. Brush facing the mirror with the front of the handle visible for the first week. You'll learn the right pressure and rely on the light less.
"My old Oral-B heads won't fit the iO2"
They won't. iO handles only take iO heads, and iO heads don't fit classic handles like the Vitality Pro.
"The plug doesn't fit my socket"
Both chargers have a 2-pin plug for bathroom shaver sockets. Use a 2-pin to 3-pin shaver adapter for an ordinary socket.
"There's gunk where the head meets the handle"
Toothpaste collects there on every Oral-B. Pull the head off once a week and rinse both parts. Our guide to cleaning and looking after your electric toothbrush has more.
Our verdict
If money is tight, buy the Vitality Pro and don't feel you're missing out on cleaner teeth. The testers say you aren't. At £23 with two heads, and about £1.30 a month to run, it's one of the best-value health purchases you can make. Just keep it on its stand and be honest with yourself about whether you press too hard.
If you can stretch to £35, we'd buy the iO2. Not because it cleans better, but because it's nicer to live with: weeks between charges, a smoother feel, a travel case and at least some warning when you press too hard. That's worth 97p a month to us.
And if pressure is your real problem, skip both and look at the iO3.
Frequently asked questions
What is the difference between the Oral-B Vitality Pro and iO2?
The Vitality Pro is a classic Oral-B with a mechanical rotating head, no pressure sensor and about one to two weeks of battery. The iO2 is the cheapest model in Oral-B's iO range, with a smoother magnetic drive, a red pressure light and around five weeks of battery in independent tests. They use different brush heads.
Is the Oral-B iO2 worth the extra money over the Vitality Pro?
If you want a pressure warning, long battery life and a smoother feel, yes. At our prices it costs about £12 more up front and about 97p a month more over three years including heads. Independent testers found no real difference in cleaning, so it's a comfort and convenience upgrade rather than a cleaning one.
Does the Oral-B Vitality Pro have a pressure sensor?
No. Electric Teeth and Tech Advisor both confirm it has no pressure sensor of any kind. If you tend to brush too hard, the iO2 has a basic red light and the iO3 has a clearer light ring.
Does the iO2 clean better than the Vitality Pro?
Not by much, if at all. Electric Teeth found the iO2 cleaned just as well as Oral-B's classic Pro 1 and Pro 3, but no better, and Tech Advisor said the Vitality Pro is good enough even though iO brushes are more effective. Technique matters far more.
How long does the Oral-B Vitality Pro battery last?
Electric Teeth got 17 days in testing and Tech Advisor got around a week, against claims of 8 to 10 days. It takes up to 22 hours to charge fully and has no battery indicator, so keep it on the stand.
How long does the Oral-B iO2 battery last?
Oral-B says up to four weeks. Independent testers did better: Electric Teeth measured 37 days, T3 five to six weeks and Expert Reviews about 53 days at four minutes a day. It's one of the longest-lasting Oral-B brushes.
Can I use Vitality Pro brush heads on an iO2?
No. The iO2 only takes Oral-B iO heads, and iO heads don't fit the Vitality Pro. The Vitality Pro takes classic Oral-B round heads such as Precision Clean, CrossAction and Sensitive.
Which is cheaper to run, the Vitality Pro or iO2?
The Vitality Pro. At our prices classic heads cost about £1.99 each in a 12-pack, while iO heads cost about £3.91 each in an 8-pack. Over three years, including the handle, that's about £46.91 for the Vitality Pro and £81.86 for the iO2.
Which is better for sensitive teeth?
Both have two gentle modes: Sensitive Plus on the Vitality Pro and Super Sensitive on the iO2. The iO2's smoother drive and pressure light make it the better choice for most people with sensitive teeth or gums.
Is the Vitality Pro good for a first electric toothbrush?
Yes. It has the two-minute timer with 30-second nudges, which is the feature that makes the biggest difference for people switching from a manual brush, and it costs about £23. Its main gaps are the lack of a pressure sensor and short battery life.
Is the Oral-B iO2 quieter than the Vitality Pro?
Only a little at full power. Electric Teeth measured 73 dB for the Vitality Pro and 72 dB for the iO2 in Daily Clean. In the iO2's gentle modes it drops to about 64 dB, which is noticeably quieter.
Do the Vitality Pro and iO2 have a travel case?
Our Vitality Pro comes with the handle, two heads and a charging stand, but no travel case. All three of our single iO2 sets include a travel case.
Which Oral-B should I buy if I brush too hard?
The iO3. Its light ring shows white for too little pressure, green for right and red for too much, and reviewers found it far easier to see than the iO2's small red light. The Vitality Pro has no sensor.
