Early users of Dyson's CameraJet smart toothbrush report water damage to the battery compartment within days of use. One user claimed their unit broke within 30 seconds.

Dyson's newly launched CameraJet, priced at $499.99, is experiencing widespread water infiltration issues. The AI-powered toothbrush features a built-in camera designed to detect gaps between teeth and automatically spray mouthwash into targeted areas. Complaints have surfaced on Reddit's r/Dyson community, with users reporting that moisture is entering the device's battery compartment—a critical flaw for a product designed to work inside the mouth. The apparent design flaw raises questions about the device's water resistance specifications, particularly given its premium price point and primary use case. Dyson has not yet publicly addressed the reported failures or issued guidance for affected users. The CameraJet represents Dyson's entry into the smart oral care market, but these early reports suggest potential quality control concerns ahead of wider availability.
