Early users of Dyson’s $499.99 CameraJet electric toothbrush report that water is getting into the device’s battery compartment. One Reddit user wrote that their model “broke within 30 seconds,” while another user from the United Kingdom said water had entered the battery compartment of what appeared to be a malfunctioning unit. Responses to the posts suggested that the issue could be affecting multiple devices.
In a statement to The Verge, Dyson said through Kaitlyn Coleman, Senior Communications Manager for Home Technologies, that a small number of CameraJet units from its early production batches may have experienced a component issue.
CameraJet, Dyson’s first smart toothbrush, features a camera, artificial intelligence and a water jet function that sprays mouthwash between the teeth to mimic flossing. The product sold out on Dyson’s website shortly after launching this week. The company said the shortage was not because it had withdrawn the product due to complaints, but was caused by strong global demand and supply shortages as production was being ramped up.
A test conducted by The Verge in Berlin using a fake mouth setup found that the CameraJet could get wetter than a regular toothbrush. Dyson said it had separated the affected early batches and taken the necessary steps to support customers.
Why it matters
These claims directly call into question expectations for durability and safety in a new water-powered smart device with a battery compartment. For users who bought the product from the initial batches in particular, the issue is not only brushing performance, but also how a faulty unit will be replaced and what company support will cover. Dyson’s statement that it had separated the early production batches does not establish with certainty whether the problem extends to all products; the available information also does not disclose the number of affected devices. The fact that the product sold out within a short time suggests that those waiting for stock and those who made a purchase may face the same uncertainty. The open question is how the source of the component problem and the units it covers will be clarified.
