Dyson's $500 CameraJet trades the floss for a camera and a change of toothpaste
Dyson's record says the difference between a category-maker and a write-off is whether the annoyance being solved was real. The CameraJet puts that judgement on public test. The engineering was never the hard part.
The Board Room · Leadership desk
What happened
- Dyson has launched the CameraJet, its first toothbrush, which uses a built-in camera and LED to find the gaps between teeth and fires a conical jet of mouthwash into them as the user brushes.
- The brush vibrates at up to 58,000 times a minute, and its software anticipates where the gaps will be so that the spray lands at the right moment and place.
- Using it as designed means foam-free toothpaste, a horizontal grip and slow oval movements, and Forbes' reviewer treats the how-to videos in the MyDyson app as near-mandatory.
- When toothpaste builds up and the camera can no longer see, the mouthwash jet stops until the user spits out the paste and resumes.
- Dyson's website carries a Q&A on in-mouth camera privacy, saying the camera is optimized for short-range vision and detection only and that images are deleted from the app immediately after viewing.
Why it matters
- What doesn't add up contradiction The same price supports two readings: Forbes finds it compares well with the dearest Oral-B and Sonicare models, while GlobalData's Neil Saunders calls that sum a big ask for a simple product. Which reading holds decides whether this is a premium tier or a niche.
- Who's exposed exposure Dyson's assurance covers retention and range, not compromise, so owners carry the residual risk that the software keeping the lens short-range and the images transient stays intact.
- What it sets up precedent Business Insider's read is that Dyson is testing tolerance for cameras in ordinary objects; if twice-daily use sticks, the next appliance maker proposing a lens in a bathroom has an easier argument to make.

Albertsons pulls its financial guidance until its sweeping business review is overConfirmed2 publishers
Dyson's biggest wins took a step out of a chore. The DC01 removed the vacuum bag in the UK in 1993, and the machines are still selling 33 years on [15]. The Air Multiplier removed the blades and the grille in 2009, and the same motor and aerodynamics went on to power the hand dryers in public restrooms [18]. The CameraJet reverses that arithmetic: it removes flossing with synthetic plastics [8] and charges for it in technique and in a change of toothpaste [5][9]. That leaves the return on the development programme resting on whether people will relearn how they brush.
The failure Dyson has already diagnosed for itself was a category problem rather than a compliance one. Jake Dyson said of the $949 Zone headphones that customers could not tell whether they were buying headphones or an air purifier, and that the company often works in an obsessive nature before evaluating what the market response might be; his conclusion was that the market did not exist [16]. The CameraJet carries no such ambiguity about what it is. The risk has moved to price and routine.
What a misdiagnosis costs is also on Dyson's own record. The N526 electric SUV, aimed at roughly 600 miles of range on a charge, absorbed about $750 million across five years of research and development from 2014 before Dyson scrapped it in 2019 as commercially unviable, and no car reached a customer [19]. That averages about $150 million a year [24], and at the brush's list price Dyson would need to gross roughly 1.5 million units to match what the car programme spent [25]. The toothbrush programme ran a year longer than the car's did [26]. The accuracy of the initial judgement about which annoyance is real is the scarce input here, not engineering appetite.
Neil Saunders of GlobalData put the skeptic's case to Business Insider: Dyson is at its best solving genuine problems that many other products fail to, and its big flops come when it offers solutions to things that are not really problems [17]. On flossing specifically, the record available is thin, because the evidence that this is an annoyance people will pay to remove is currently Dyson's own marketing line that few of us floss even though we know we should [7]. We do not yet know how many buyers agree at this price.
Dyson has pre-empted the privacy question with an FAQ, not settled it. Business Insider says it asked Dyson for more detail on the camera and had no immediate reply [22]. The brush also streams a live view of the inside of the mouth to the MyDyson app [6], so frames leave the device by design, and Business Insider's reminder that a fleet of camera-equipped DJI robot vacuums was remotely accessed [23] is the reason a stated retention policy and the software enforcing it are separate questions.
The likeliest outcome is a modest, durable niche seller, not a clean hit or a write-off. Dyson built a 90-sensor robot vacuum prototype in 2003, judged it too complicated and expensive to sell, launched the camera-equipped 360 Eye in 2015, and still sells robot vacuums without the category ever becoming a second bagless breakthrough [20]. A line that sells respectably to a narrow band of buyers never forces the decision that $750 million forces [19]; it holds engineering bench and shelf space for a decade instead. That is the outcome worth pricing this quarter, and the one that is hardest to see arriving.
What to watch
- Whether Dyson answers the outstanding questions on how camera frames are handled between the brush, the app and its servers.
- Whether the foam-free paste and mouthwash become a repeat-purchase line rather than an in-box accessory.
- Whether Dyson discloses any sell-through, restock or return figures, or widens availability beyond the launch markets.

Claim ledger
Ranked by verification strength, evidence, and original report placement.
- [1]
Dyson launched the CameraJet, its first toothbrush, which has a camera and LED built in; as the user brushes, the camera sees the gaps between teeth and a conical jet of mouthwash is sprayed with some force at teeth and gums.
- [2]
The CameraJet is available to order from launch day and costs $499.99 in the US and 419.99 pounds in the UK.
- [3]
Dyson spent six years developing the brush, and the mouthwash sits in a 12.5ml reservoir designed so that it does not stop or clog whichever way up the brush is held.
- [4]
The brush vibrates at up to 58,000 times a minute, and the software anticipates where the gaps are as the user brushes so it can spray the liquid at the right time and place.
- [5]
To see clearly in the mouth the brush needs non-foaming toothpaste, meaning paste without sodium lauryl sulfate; Dyson has devised its own and supplies a tube along with a bottle of Dyson-recipe mouthwash.
- [6]
The user can watch a livestream of the inside of their mouth on the MyDyson smartphone app.
- [7]
Dyson is aiming to market the brush to people who are not good at keeping up with flossing, saying: Few of us do it even though we know we should.
- [8]
The CameraJet promises to remove the annoyance of flossing with synthetic plastics, but also asks users to be comfortable with a camera peering at their teeth.
- [9]
The user must hold the brush horizontally and move it in slow, oval movements for it to see the gaps, and the reviewer describes the how-to videos supplied in the MyDyson app as kind of mandatory viewing.
- [10]
Dyson recommends smiling while brushing to help the camera do its job, which means toothpaste goes everywhere and there is a bit of clean-up needed afterwards.
- [11]
If toothpaste builds up the camera cannot see, so the jet of mouthwash stops; the user can turn the brush off, spit out the paste and carry on, and the timer is smart enough to know this is happening.
- [12]
Business Insider argues Dyson is testing consumer acceptance of cameras in everyday items, placing the brush alongside video doorbells, robot vacuums with cameras and sensors that map homes, high-end fridges that peer at shelves and an AI toilet that tracks health.
- [13]
Forbes writes that the price is not cheap but compares well to the most expensive versions of electric toothbrush from brands like Oral-B and Sonicare.
- [14]
Saunders calls the brush innovative and very clever, but also a big ask to expect consumers to fork out such a huge sum of money on a simple product.
- [15]
James Dyson refined cyclonic technology to separate dust from air without a bag and brought the bagless DC01 vacuum to market in the UK in 1993; Dyson's vacuums are still popular 33 years later.
- [16]
Jake Dyson, the founder's son and chief engineer, said the problem with the $949 Zone air-purifying headphones was that customers did not know whether it was headphones or an air purifier, telling Wired in 2025: quite often we work in an obsessive nature, sometimes before actually evaluating what the market response might be, and the market didn't exist.
- [17]
Neil Saunders, a retail analyst at GlobalData, told Business Insider that Dyson is best when it solves genuine problems that many other products fail to, and that big flops occur when the company comes up with solutions to things that are not really problems.
- [18]
Dyson launched the Air Multiplier bladeless fans in 2009, hiding a motor and impeller in the base to propel air through a ring-shaped top, and the same aerodynamic and motor technology now powers Dyson's hand dryers found in public restrooms.
- [19]
In 2014 Dyson set out to build an EV SUV, the N526, with around 600 miles of range on a charge; in 2019, after spending about $750 million on five years of research and development, it scrapped the project, saying it could not find a way to make the car commercially viable, and the cars never reached consumers.
- [20]
Dyson built the DC06 robot vacuum prototype in 2003 with removable batteries and 90 sensors but decided it was too complicated and expensive to sell; it launched the camera-equipped 360 Eye in 2015 and still sells robot vacuums, but the category has not become Dyson's next bagless-vacuum-style breakthrough.
- [21]
Dyson's website carries a Q&A section titled Are there privacy risks with an in-mouth camera?, saying the camera is optimized for short-range vision and detection only and that images are deleted from the app immediately after viewing, not stored or shared.
- [22]
Business Insider says it asked Dyson for more details on the privacy aspects of the camera and did not immediately hear back.
- [23]
Business Insider recalls that someone managed to remotely access a fleet of camera-equipped DJI robot vacuums.
- [24]
The scrapped N526 programme averaged about $150 million a year of research and development spending.
- [25]
At the CameraJet's $499.99 list price, Dyson would need to gross roughly 1.5 million brushes to match what the abandoned car programme spent.
- [26]
The toothbrush's six-year development ran one year longer than the five years of research and development the EV programme received.
