Dyson has confirmed that a small number of early production batches of its £419.99 CameraJet AI toothbrush experienced a component issue, reportedly water seepage from faulty jet tubes that can impair performance. The company says impacted inventory has been isolated, full production has resumed, and affected customers are receiving full refunds.
Dyson has confirmed that early batches of its £419.99 CameraJet toothbrush suffered a component issue, following customer complaints that the device slowed down or stopped working, and said customers with affected units will receive a full refund. The company entered the oral care market on 1 September with the AI-powered toothbrush, which combines a water jet and an internal camera, making the fault an early setback for one of its most expensive consumer launches.
In a statement published on its website on 21 September, Dyson said it was “aware that a small number of early batches of products have experienced a component issue”. The company said it had isolated those batches and was “taking all the necessary steps” to support customers. It directed customers with questions or faulty units to contact customer service, adding: “Where a customer has an impacted unit, we are providing a full refund.”
The acknowledgement followed complaints on social media from customers who said the device had slowed down or stopped working. One user on the Dyson forum on Reddit, @commanderxhalo, said the CameraJet was unresponsive after one use and that he found water in the battery compartment. Five other users — @mwindsor0, @simphe, @shaunshady, @raphlondon and @cocooned — replied on the thread saying they had also encountered issues with the device.
In a subsequent statement to Bloomberg News, a Dyson spokesperson elaborated and apologised to affected customers. According to Bloomberg’s report, the spokesperson said “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 demand globally” and said supply shortages were expected to ease as production scales up, with the next wave of product available “in the coming weeks”.
Early Setback in Dyson’s Oral Care Push
The fault comes at a sensitive moment for Dyson, which has been expanding beyond its core vacuum and Airwrap hair businesses into premium personal care categories. The CameraJet, six years in development and priced at £419.99, is the flagship of the company’s first own-brand dental care line, launched on 1 September.
A widely publicised component fault in the first weeks of a flagship launch can weigh on consumer trust in a product category where Dyson has no track record. The company’s decision to publicly isolate affected batches and offer full refunds is an attempt to contain that damage, but the episode also coincided with the device going out of stock, which limits its ability to rebuild momentum quickly.
The launch also carries financial weight: Dyson reported that profits halved in a “difficult” year despite record sales volumes, raising the stakes for new categories such as oral care to deliver growth.

How the CameraJet Works
The CameraJet is a dual-bristle toothbrush with a water jet designed to tackle plaque between the teeth. A camera using AI-powered Gap Optical Targeting technology acts as a high-quality endoscope to identify gaps that need precision flossing.
Inside the brush, a 100k-pixel macro lens powered by machine learning detects, tracks and predicts gaps between teeth in real time, triggering a burst from the water jet. The device runs on 16 million lines of code, with a machine learning system trained on 470,000 dental images collected during development.
The reported fault — water seepage from a jet tube, with at least one user reporting water in the battery compartment — sits at the intersection of the device’s two headline features: the water jet system and its dense electronics.
“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.”

Unanswered Questions on Scale and Safety
Dyson has not said how many units were affected by the component issue, describing it only as “a small number” of products from early batches. The exact number of devices sold, and the proportion faulty, remains unclear.
It is not confirmed whether the water seepage poses any safety risk beyond performance problems; Dyson’s statements have referred to performance effects, and the company has not announced a formal product recall. Cosmetics Business has contacted Dyson for further comment, and no response beyond the published statements has been reported.
Individual user reports on Reddit — including the claim of water in the battery compartment — are customer accounts that have not been independently verified.
Restocking and Refund Rollout
Dyson says the CameraJet is now in full production and shipping to partners, with the next wave of product expected to be available “in the coming weeks”. Customers who experience an issue are being directed to Dyson customer service, with full refunds offered for impacted units.
Further clarity may come from any additional Dyson comment, and from whether the company discloses the scale of affected units or issues any broader customer notice beyond its website statement. Early sales performance once restocked will indicate whether demand holds after the fault reports.
