Notice they don't include ultrasonic and rotating brushes in that statement.
There are also studies that show that electric is better, like this meta-analysis that found a small effect [2] and this Cochrane review. [3]
What I generally read in articles is that the single biggest thing that makes a difference is brushing for the full 2 minutes, and electric toothbrushes can help with that by having a built-in timer.

> Dyson’s brushing action prevents stalling, keeping bristles in constant motion to remove more plaque vs. market leading premium electric toothbrushes in a laboratory test in brush-only variable mode in the hard to reach areas. [0]
Maybe one was an actual, independent though Dyson funded study and the other just their internal comparison to competitors? When I last upgraded my electric toothbrush, I read some studies looking into performance of Oral-B and co. and, to a layman, it seemed like most proper independent studies used manual as the base line.

Edit: here are some anecdotes https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d...
Edit 2: It might be that I didn’t maintain it properly and the water reservoir was building up bio film over period of time and actively distributing bacterial to my gums.
Not in any way knowledgeable on Dental Hygiene, so take this for layman's advice from someone who has used a water flosser for half a decade to positive effect: To anyone reading, please read the instructions in terms of proper usage, how to place it, etc., don't go full blast in the first few weeks and absolutely clean it according to the instructions. At least always empty the water fully and dry it out with the reservoir opened.
Not saying this is what caused your negative experience, mind you. Again, Dental is not my field (Dentists, feel free to correct me if anything I wrote is wrong), but from my understanding and reading (I did read some papers when deciding to buy my first, cause of course I do my purchasing decisions on PubMed), some peoples gums seem to be simply more sensitive [0] to water flossers, even with proper device maintenance. In the end, always clear with your dentist.

That said this looks like a ridiculously overengineered product. Electric toothbrushes have come a long way, at a fraction of the price.
Edit: Ah a gum problem, yeah I've been warned about that (by a dentist no less). I just use interdental brushes.
I believe that sometimes there are bad outcomes from standard medical advice—humans are messy and the world is complicated—but I would like to know much more about the failing case before making a judgement.
My feedback:
1. It works great. I had to empty it several times because it was picking up so much more stuff than our existing vacuum did - mostly pet hair and the like.
2. It's the one with the little laser thing, which is a dumb little gimmick until you see it in action and then it's life-changing - if you're like me and find satisfaction in picking up every invisible crumb anywhere.
3. After a year and a bit, maybe less, it started misbehaving. It would suddenly turn off, then you'd have to let go of the trigger and pull it again; then it would work fine. Then it would happen a few times until it worked fine. Then it almost never worked fine. I kind of tolerated it for a while until I got fed up and googled the problem, and it was suggested to buy a new housing - the electronics plus the motor, basically the whole 'vacuum' part of the vacuum, which was only just over a hundred dollars direct from Dyson. Irritating to have to spend an extra hundred bucks to get my five hundred dollar vacuum working as expectred, but expected it to cost far more.
Would I recommend it? Not sure. It's very expensive, it works very well; it has a nice wall mount that charges it and which holds a small subset of the attachments it comes with. I'm glad I have it and I use it often.
Yes, it's plastic, but if it were, for example, steel or aluminium then it would be too heavy to use for any length of time. As it is, it feels very sturdy and has held up physically very well, but I'm obviously also not rough with it so there's no reason it would have any issues unless it were, in fact, cheaply or poorly made.
Going on 13 years now I think.
It's a cheap part to replace. It also means a complete disassembly! A lot of it isn't hard but there are some wires that have to snake around, and popping out certain things requires some scary use of force. It took like 3 hours to do for mine.
Also these things don't seem to be great at battery maintenance. I forget how long that took me but it didn't leave any scars, I think it was easy. Just, more expensive. Less so now that batteries are cheaper. But I have my suspicion that their float charge mode is maybe not good & injured batteries. I specifically avoided that but still had issues.
The trigger really made me mad when I finally dug it out of mine. It was such a blatantly obviously designed-to-fail system. It really makes me super distrust this company.
Due to the unfortunate quirk of language, its hard do describe how much better I like my Meile bagged vacuum than my Dyson. See my Dyson sucked, but the Meile really sucks.
My cleaners moaned about the Dyson but they love love love the Henry.
Our Dyson is cordless and so so so convenient for a quick 15-20s cleanup after kids dinner etc. Grab and go.
So we persoanlly use the Dyson for day to day cleanup, and the cleaners use the Henry when they come.
As someone in the market for a new (portable) vacuum cleaner, who has a Dyson now and no longer wants to, is there really nothing out there that isn't so flimsy and plasticky and still portable?
The new one just feels sort of flimsy in all sorts of ways, definite buyers remorse, the old one just felt indestructible + really powerful, this seems a bit crap.
That's not to say it's a bad product, but I've had my Henry vacuum for decades, and in that time it's been kicked down the stairs and used vacuum up all kinds of stuff it probably wasn't design for, but it's still just as good as the day I got it.
I bought a Dyson vacuum and it felt like cheap garbage, to the point that I returned it. I didn’t trust that it would hold up. It creaked and jangled around. The feel did not match the price tag.
Other plastic products, like the old polycarbonate Macs, felt very solid and well made.
I would - rather it is. My grandfather had a kirby for decades. I've had a kirby for decades. Though mine has the transmission power drive that makes it a joy to use.
I can not imagine ever buying a plastic vacuum.
When I worked there they were always really worried about Shark, because apparently they have better pick-up benchmark scores. I bought one recently. Absolute trash. It has some bullshit automatic power control thing that is on by default but just varies the power completely randomly. So every time you turn it on it takes about 5 seconds - on, low power, high power finally. Vs the Dyson where you just pull a trigger.
Never again. Dysons are the best. Very expensive, but just buy the older models or refurbished.
Also don't bother with the hair drier or the cold fans. Not worth the price. The hot fans might be I guess.
I’m not usually a conspiracy theorist, but if I was a product engineer looking for a way to make my well-engineered product fail just after the warranty period was up, that trigger failure looked like a pretty good candidate. There was a specific piece of the plastic that looked like it was ostensibly there as a structural reinforcement, but it was clearly too short, and the trigger had cracked just past it.

But for a cordless stick vacuum I do like the basic design. For real vacuuming I choose my Sebo E3 every time, but it's not nearly as quick to use as a cordless stick.
One of the best things you can do for a Dyson stick vacuum, in my humble opinion, is get an adapter so you can use something like a Milwaukee tool battery.
Dyson CameraJet™ is clinically proven to be more effective in improving gum health by removing and preventing plaque buildup.² Vs a manual tooth brush. "
So they didn't dare compare it against a 20 EUR Braun Oral B?
Here I am in a hotel room with a Dyson fan, which simultaneously moves less air, and is more noisy, with a much more piercing tone, than my home fan with blades that I bought for £30 from screwfix.
I'll be turning it off before I sleep... unlike the one at home.
Only an impeller with blades

From https://www.galaxus.ch/en/page/dysons-electric-brush-sprays-...
At least I do use all of that to properly clean every area and if they do it simultaneously to regular 2min+ brushing, I'm interested to see how that works in terms of water usage. Likely why they got the camera, for short bursts, looking forward to read some papers on how well that truly works vs a consistent stream.
Besides that, I personally always liked the totally round, smaller Oral-B heads vs Philips and other electrical toothbrushes, mainly cause that's what I grew up on. Seems Dyson is somewhere in the middle, smaller than most but not quite fully round.
Price as mentioned is a lot, but not unprecedented for those just buying the iO Series 10 or Philips equivalent + an Aqua flosser. Though there is no real reason to go for the 10, e.g. 8n is identical even in the superfluous comfort features at often less than 50%.
I've owned water jets, the ones I've had suck. I always end up going back to dental floss. These days string on a plastic holder which I hate because it feels so wasteful to have all that single use plastic, but they are just so effective and I hate the manual wrapping of string, so I accept the wastefulness reluctantly.
This product potentially hits home with what I'd want from an effective waterjet, and it also comes with a brush on top.
The price is high, that's for sure, but I'm guessing they aren't aiming at the average electric tooth brush market, more like a competitor to the oral b io series 9 segment. And sure they are quite a bit above that price point, but they got a lot more of a solution backing the price.
just like midwives they all seem to have their own opinions that dont equate to scientifically researched advice, yet are presented in a way that if you;re not paying attention will be taken as such.
Surprisingly, $30 for two replacement heads is comparable to other electric toothbrushes (not counting third-party bulk knockoff replacements, which I have been using for years without issue). The RFID reader might force you to buy the official replacements, though.
The Oral-B Genius X with A.I. Rechargeable Toothbrush will transform the way you brush for healthier gums and stronger teeth for life*. The dentist-inspired round brush head surrounds each tooth to remove more plaque along the gumline vs a regular manual toothbrush.
But I find myself a bit skeptical. Would love to see some long-term third party testing on it.
Any time I’ve bought something with frequently out of stock consumables, it’s been a mistake. It quickly falls out of favor.

My impression is they're actually way overpriced relative to their quality/value, and get away with it due to effective marketing and aesthetic design.
To be fair, I've never owned a Dyson product, but have used them, and they just seem meh at best.
Just really surprised to see a Dyson announcement get upvotes on HN.
My current vacuum is a V15, and I like it a lot. It was expensive (and a gift), but it's very effective, has a lot of attachments to make it easier to clean upholstery/the carpet/a computer/drawers/hardwood/the window frames/whatever, comes with a wall mount that the cable connects to so you can just put it in the mount and it charges. The one issue I had seems to be a relatively well-understood issue with the electronics, which resulted in me having to spend another $100+ on a new housing - the electronics + motor + LCD screen + etc., basically the whole 'vacuum' part of the vacuum. Given how well it's treated my so far, though, I'm not too miffed.
Our last vacuum (which we still have) was a Miele, and while it was also fantastic it was far more of a pain in the ass since it's a plug-in with a bag vs. a cordless canister. The quality is similar, I think the Dyson is a bit better, but I use it exclusively because it's far easier to go get it, vacuum up a spill, and put it back. I know that's more of a comparison between canister and bag vaccums, but the fact that they're around as effective despite the dyson being a canister is I think a point in its favor.
Whether all of their stuff is as good, or only the more expensive stuff, I can't say.
4k resolution mouth camera?? That's why we go to a dentist every 6 months because I wouldnt know wtf im looking at.
"Oh there's that canker sore I feel. Huh, at least I can see it"
Bruh, you don't need a camera for gap detection. Just stick an IR sensor, detect change in light. Boom, $0.05.

It's a bit hard to find toothpastes without it that aren't also fluoride free, but they exist.
I suffered from incredibly painful month+ long lasting chronic canker sores (technically apthous ulcers) for the first 3 decades of my life.
Doctors and dentists suggested all the usual triggers (avoid SLS, supplement with B vitamins, etc)
Then one day someone mentioned the connection of NSAIDs and ulcers, and I instantly realized mouth ulcers are.. ulcers...
I used to use ibuprofen occasionally, often enough to not correlate it to canker sores. Of course then I’d use more ibuprofen for that pain, get more canker sores, and be miserable for months.
Haven’t bought ibuprofen for 10 years now and they just stopped. I have used ibuprofen on a couple occasions since I learned this and both times I developed a canker sore. IANAD, YMMV, I’m just happy they’re gone
On paper it looks like a solid application of vision models.
The camera is for the ai: "Dyson's Gap Optical Targeting™ prevents plaque formation by detecting the gaps and jetting between teeth every time you brush.²"
Technology marketing continues to suck wealth away from consumers.
Putting the word "camera" in the name seems pretty dumb, but who knows? Maybe I'm the dumb one.

I would be disinclined to use it. It reminds me of the Astral Codex Ten Article about the Midjouney Scanner https://www.astralcodexten.com/p/preliminary-thoughts-on-the... , as well as those who've had problems with AirPods. https://discussions.apple.com/verify-human/verify.html?next=... (42 pages) What sounds the most amazing in a press release is often not the most medically sound.
Edit: it's hard to find clear info on the risks of improperly using an electric toothbrush or even on overbrushing, let alone the Dyson one, in part because a lot of search results are blogspam. Hopefully if the Dyson one is stronger, they don't use that to give it a default that is too much pressure, whether of water or moving bristles. I don't know that water pressure would cause enamel to come off. As for pressure using bristles, there is a point of pressure at which the cleaning effect stops increasing, and it is better not to go beyond that. Right now it's unclear to me whether the Dyson toothbrush works especially well or not.
That is what I call not "slop".
It is not good security practice to publish your random word passphrases as the title of an article.
Thank you for your time
