Dyson's New CameraJet Toothbrush Uses a Lens to Target Gaps Between Teeth, Reporter Accidentally Sprayed in the Eye During Hands-On

A jet of water shot out from between the teeth of a denture model, followed by a burst of minty irritation across the reporter's face — this was Engadget's Mat Smith's firsthand experience testing Dyson's new CameraJet toothbrush in Berlin. He accidentally switched the device to manual spray mode, and the demo denture model sprayed straight back into his face.

The launch event was held right before IFA Berlin officially opened, where Dyson rolled out its full lineup — robot vacuums, hair dryers, and air purifiers — but CameraJet was clearly the star of the show. This product combines a toothbrush and water flosser into a single device. The name doesn't exactly scream "oral care product," but the functionality underneath is genuinely intricate. For hygiene reasons, the reporter couldn't test it in his own mouth and had to rely on the denture model provided on-site.

CameraJet can switch between brushing mode and flossing mode, or run both simultaneously. Its built-in "Gap Optical Targeting" system processes 28 images per second, locking onto the gumline and gaps between teeth before firing a precise stream of water — theoretically more water-efficient than a standard water flosser. Mat Smith initially worried the water tank might be too small, but in testing, he was able to run two full rinse cycles on the denture model without needing a refill. He described CameraJet as feeling a bit bulky when used as a toothbrush, but surprisingly light and easy to hold when used purely as a water flosser.

The more critical difference lies in the trigger logic: CameraJet only releases water when it detects a gap between teeth, rather than blasting continuously the moment it's powered on — a notable improvement over the reporter's own Waterpik at home, which he says is perpetually covered in water stains. This makes the manual-mode mishap all the more ironic, as it was one of the few moments in the entire demo where things actually got out of control.

Camera Streams Live to Your Phone, Dyson Insists Footage Never Leaves the Device

Tucked into the front of the device is a tiny 100,000-pixel camera that streams a live feed to a nearby iPhone running Dyson's dedicated app. The image quality resembles that of a medical endoscope, and given all the vibration, water flow, and angle changes involved, the clarity exceeded expectations. As for whether the camera can still see clearly while actually brushing with toothpaste — especially foaming varieties — there was no chance to verify this on-site.

A built-in camera connected to an app naturally raises privacy concerns. In response, Dyson repeatedly emphasized that the video stream exists only on the user's own phone, is never uploaded or processed elsewhere, and remains completely private — though this is the brand's own claim, and no third-party verification has been conducted yet.

Price is an unavoidable topic for a product like this. CameraJet is priced several hundred dollars above even the top-tier Philips Sonicare or Oral-B iO models currently on the market, and the water flosser function comes built-in rather than as an add-on accessory. The replacement brush heads, dedicated non-foaming toothpaste, and specialized mouthwash used with it are all part of Dyson's own product line — though officially, users are permitted to use toothpaste and mouthwash from other brands.

Notably, even before CameraJet officially ships, Dyson has already flooded its YouTube channel with tutorial videos — down to the granular level of teaching users how to factory-reset the device and how to switch it into "travel mode" to prevent it from accidentally powering on and draining its battery if compressed inside a suitcase. When Mat Smith flew back from Berlin, he didn't have a test unit with him, so he wasn't able to personally verify whether this travel mode actually works as intended.
