Dyson’s debut electric toothbrush, the CameraJet—priced at around ¥3,356—features an integrated camera in its brush head for real-time brushing visualization and AI-driven detection of interdental gaps to trigger targeted mouthwash spraying. However, within two weeks of its release, users began reporting instances of water seepage into the battery compartment. In response, Dyson acknowledged that a limited number of units from initial production batches suffered from component defects but stopped short of issuing a recall or outlining a comprehensive fix. Instead, the company advised affected customers to reach out to its after-sales support team. Industry experts warn that such lapses in waterproofing design could tarnish Dyson’s reputation for engineering excellence.
