Dyson has fitted an RFID tag to every brush head of its first electric toothbrush, using the tag to count how many times each head has been used and to tell the owner when that head is worn out. The CameraJet was launched on 1 September 2026 by Dyson, the British engineering company best known for vacuum cleaners and hair care. It costs USD 499 in the United States and GBP 419.99 in the United Kingdom, sold through Dyson Demo Stores and Dyson’s own website.
The tag does three jobs. It registers that a head has been connected to the handle. It identifies which variant is fitted, either the dual-bristle standard head or the dual-bristle sensitive head. And it lets the handle keep a running count of the cleaning sessions performed by that specific head, so the brush can say when it is time to replace it. Dyson’s own UK support and store pages describe the heads as carrying integrated RFID that tracks wear and prompts replacement.
That last function is the interesting one, because it changes a piece of advice into a measurement. Dentists generally recommend replacing a brush head every three months, which is a reasonable average and a poor fit for any individual. A count tied to the specific head replaces the guesswork with an actual usage figure. The heads are a genuine consumable: a pack of two standard heads is GBP 25 in the UK, with a subscription option that saves 10 percent, and the device is designed to work only with Dyson’s own heads.
RFID has reached the bathroom cabinet
Reading a tag on a toothbrush head sounds faintly absurd, and that is rather the point. Consumable identification is one of the oldest and least glamorous applications of RFID, and it has been quietly working its way down the price ladder for two decades. Printer and toner cartridges were the early example. Since then the same pattern has appeared in medical and laboratory consumables, coffee machine pods and capsules, water and air filters, cordless power tool batteries, and the disposable tips used on professional cosmetic and dermatology devices.
The mechanics are consistent across all of them. A low-cost tag is moulded into or stuck onto the consumable, a small reader sits in the host device, and the tag carries an identifier plus, in many implementations, a rewritable memory area the host updates as the part is used. From that the host can confirm the part is genuine, adapt to the variant fitted, and track remaining life. Different products use different operating frequencies depending on read range, cost and material constraints, and Dyson has not stated which the CameraJet uses.
A toothbrush head is a demanding home for a tag even so. It is a small moulded plastic part made in high volume at low unit cost, permanently exposed to water and toothpaste, and it has to read reliably every time a half-awake human pushes it onto a handle. That a mass-market consumer product can absorb that cost and that engineering effort for what is essentially a wear counter says more about where RFID economics have landed than any deployment case study. More on where the technology is turning up in our technology coverage and RFID hardware reporting.
The rest of the CameraJet
The tag is the least visible part of a busy product. Beneath the brush head sits a 100k pixel macro lens camera, roughly 0.1 megapixel, which analyses 28 live images per second. A machine learning system Dyson calls Gap Optical Targeting detects, tracks and predicts interdental gaps in real time. Within 100ms of the camera seeing a gap, the device fires a burst of mouthrinse at it, delivered as a cone-shaped spray rather than a needle jet to keep the pressure gentler on gums and enamel. A 12.5ml anti-gravity tank and a diaphragm pump supply the fluid, and the refill dock tops the tank up in about three seconds while charging the handle between uses.
Dyson says the machine learning model was trained on 470,000 dental images collected during development, and that the finished product runs to 16 million lines of code. The company claims the CameraJet removes 69 percent more plaque than premium competitors in hard-to-reach areas, a figure from Dyson rather than independent testing. Brushing uses variable sonic oscillation technology.
Connectivity is Wi-Fi on 2.4GHz plus Bluetooth. The MyDyson app offers guided cleaning, technique feedback, coverage mapping, personalised insights and a live-viewing endoscope mode showing roughly what a dentist would see. Dyson states that the camera only activates during live viewing or auto-jetting, and that no images are recorded or stored on the product or in the cloud. In the box are the refill dock, two regular brush heads and a charging cable.
James Dyson, the company’s founder and chief engineer, framed the product as an answer to three problems: seeing the gaps between teeth, removing the plaque hiding in them, and improving cleaning performance while someone is actually brushing. The camera and the jet address the first two. The RFID tag quietly handles the fourth problem nobody mentions, which is that a worn-out brush head undoes a lot of the rest.
