Dyson's newly launched $499.99 CameraJet electric toothbrush is malfunctioning for some early buyers, with users reporting that water is leaking into the device's battery compartment. The issue is particularly notable given the product is a toothbrush designed for regular contact with water, and it comes just days after the AI-powered device launched with significant promotional fanfare. Dyson has acknowledged the problem but maintains it affects only a limited number of units.

Multiple Reddit users, including one who said their unit "broke within 30 seconds" and a UK-based user who found water inside the battery compartment, reported similar faults on the r/Dyson subreddit. Dyson told The Verge that "a small number of early batches" of the CameraJet had experienced a component issue and that it was isolating affected batches while supporting customers. The company denied the product had been pulled from sale, attributing its current unavailability on Dyson's website to strong global demand outpacing production. The CameraJet features a built-in camera and a water-jet function that sprays mouthwash between teeth to mimic flossing, and The Verge's own hands-on testing at the product's Berlin launch event found it could get notably wetter in use than a standard toothbrush.
