Dyson recently launched the CameraJet, a $499 electric toothbrush featuring a macro-lens camera and a fluid reservoir. The device utilizes a targeting system trained on 470,000 dental images to direct mouth rinse into gaps between teeth. Development of the product spanned six years and involved 38 patents.
Following its September 8 launch in the US, users reported water leaking into battery compartments and device failures within seconds of use. By September 15, sales were halted in the US, UK, and Singapore. Dyson’s head of Beauty Communications, Liv Thomas, stated the product has not been recalled and attributed the disappearance to strong demand and supply shortages.
The company acknowledged a component issue affecting a small number of early batches but declined to specify the faulty part or the number of units impacted. Dyson also refused to confirm where the device is currently available or when shipments were suspended. Experts from iFixit and Ripcord Designs suggest the malfunctions likely stem from waterproofing failures.
Kyle Wiens of iFixit noted that manufacturing defects in waterproofing are difficult to manage at scale. Adam Toner of Ripcord Designs observed that water ingress into the battery compartment could explain the reported charging and overheating issues. Critics suggest this situation highlights a need for Dyson to improve the repairability of its products.
