Dyson has revealed the reason behind the discontinuation of its CameraJet toothbrush, a product that was taken off store shelves shortly after its launch on September 1, 2026. In a statement shared with Bloomberg on September 29, a Dyson representative said the issue stemmed from a manufacturing defect in a component called "jet tubes," which are responsible for delivering liquid mouthwash. This defect posed a risk of water entering the device, which affected "a small number of products." Dyson has said that the affected units have been set aside, leading to the product's discontinuation in France and its removal from retailers like Best Buy. The CameraJet, priced at 479 euros in France, was marketed as Dyson's first toothbrush and included features such as a built-in camera, artificial intelligence, and an automatic mouthwash delivery system. It was designed to monitor brushing patterns and provide real-time feedback. However, users reported various malfunctions, with some devices stopping after only a few seconds of use. Some units reportedly stopped working within 30 seconds of brushing, and even replacement models experienced similar issues. Consumer Reports tested the product and found that one unit stopped after 30 seconds of use. Dyson has since resumed full production and is sending the brush to its retailers. The company apologized for disappointing customers and said it would support those affected. However, some buyers have expressed dissatisfaction with Dyson's customer service, citing delays and inadequate support. According to Bloomberg, internal sources indicated frustration with how the company managed the crisis, noting that executives who had previously praised the product on social media became quiet when customers sought answers. Dyson confirmed that the issue of water infiltration in the CameraJet was due to a defect in the jet conduits, which allowed water to enter the device and disrupt its operation. Some buyers reported finding water in the battery compartment and receiving overheating alerts. While Dyson has not provided a specific number of affected units, it emphasized that only a "small number of products" were impacted. The company also stated that no product recall was currently in progress. Dyson's spokesperson apologized for the inconvenience and said the company would do its best to support affected customers. The CameraJet was intended to be a flagship product for Dyson, following six years of research and development and the filing of 38 patents. However, the product's early failure has raised concerns about the company's quality control and crisis management. Dyson has not confirmed the exact cause of the manufacturing defect, though some analysts have speculated that it could be related to poorly adjusted parts or improper glue polymerization.
