Dyson has confirmed that a small number of early production batches of its £419.99 CameraJet AI toothbrush suffered a component issue causing water seepage and performance problems. The company has apologised, isolated the affected inventory and is offering full refunds. The device is now back in full production and shipping after temporary stock shortages.
Dyson has confirmed that a component issue affected a small number of early batches of its £419.99 CameraJet toothbrush, the company’s first product in oral care, after customers reported devices slowing down or stopping working. In a statement published on its website on 21 September, Dyson said it had isolated the affected batches and is offering full refunds to customers with impacted units.
The CameraJet, an AI-powered toothbrush with a built-in water jet and camera, launched on 1 September as Dyson’s entry into oral care, a market away from its core vacuum and Airwrap hair-tool business. Complaints surfaced on social media and on Dyson’s Reddit forum, with users reporting that the device became unresponsive after use. One Reddit user, @commanderxhalo, said he found water in the battery compartment after a single use, and several other users replied to the thread reporting similar problems.
Dyson’s website statement acknowledged the fault directly: “We are aware that a small number of early batches of products have experienced a component issue. We have isolated those batches and are taking all the necessary steps to support our customers.” The company added that customers experiencing an issue should contact customer service and that “where a customer has an impacted unit, we are providing a full refund.”
In a subsequent statement to Bloomberg News, a Dyson spokesperson apologised to affected customers and gave more detail on the cause: one production batch of jet tubes experienced a process issue, “creating a potential for water seepage which affected the performance of a small number of products”. The spokesperson said the device is now in full production and shipping to partners after going out of stock while Dyson isolated the impacted inventory. Dyson also cited strong global demand and said it expects the next wave of product to be available “in the coming weeks.”
Stakes of a Faulty Flagship Launch
The CameraJet is Dyson’s first move into oral care, a category the beauty and personal care industry has increasingly treated as a growth market. A component fault within weeks of launch puts pressure on the product’s premium positioning: at £419.99, the CameraJet is priced far above conventional electric toothbrushes, and early quality problems can shape first impressions of an entirely new product line for the brand.
The refund offer and rapid isolation of affected batches are a form of damage control familiar from consumer electronics launches, but the episode also highlights the difficulty of combining water, electronics and batteries in a single device at scale. The supply shortages Dyson described mean some customers who pre-ordered or tried to buy the device will face waits, even if their units were never affected by the fault.

From Vacuums to Dental Care
Dyson is best known for vacuum cleaners and the Airwrap hair styler, and has in recent years expanded into adjacent beauty categories including scalp care. The CameraJet, described by the company as six years in development, is its first oral care device and launched alongside a Dyson-branded dental care line.
The device is a dual-bristle toothbrush with a water jet designed to tackle plaque between teeth. A camera using what Dyson calls Gap Optical Targeting technology acts as an endoscope to identify gaps needing precision flossing, with a 100k-pixel macro lens that detects and tracks gaps in real time and triggers the water jet. Dyson says the CameraJet runs on 16 million lines of code and a machine learning system trained on 470,000 dental images collected during development. The launch came during a broader push by beauty and consumer goods companies to position elevated oral care as a premium everyday category.

Unanswered Questions on Scale and Cause
Dyson has not disclosed how many units were affected by the component issue, describing it only as “a small number” of early-batch products. The full extent of the water-seepage problem — and whether all faulty units can be identified by batch number — has not been detailed publicly.
Customer reports of faults, including the Reddit account of water in the battery compartment, are individual claims rather than independently verified findings. It is also unclear how quickly new stock will reach retailers, beyond Dyson’s statement that availability is expected “in the coming weeks,” and whether sales targets for the launch period were affected. Cosmetics Business has contacted Dyson for further comment.
Refunds, Restock and Reputation Watch
Dyson says the CameraJet is now in full production and shipping to partners, with the next wave of stock expected within weeks. Customers who experience an issue are being directed to Dyson customer service, and impacted units qualify for a full refund.
Attention will now turn to whether replacement and newly manufactured units arrive free of the jet-tube fault, and how quickly the company can rebuild availability during the launch window. Further statements from Dyson, or regulator involvement if fault reports persist, would be the next developments to watch.
