The Dyson Camerajet arrived 10 years after online rumours emerged that Dyson had filed a patent application for an electric toothbrush with water jet. True to form, it has surpassed the rumours with a toothbrush that goes one step beyond the norm and is packed with innovation. Having trialled it a week prior to launch, I was among the first journalists to give the Dyson Camerajet a hands-on review.

As the only smart electric toothbrush and water flosser with a built-in camera, the CameraJet uses imaging, machine learning and precision fluid dynamics to identify gaps between teeth and deliver a jet of mouthrinse. The CameraJet has received much attention since its launch, with many praising Dyson for pushing the boundaries with new innovation in oral health, and others questioning its price, reporting faults online, and asking whether we need a camera in a toothbrush at all. But for a brand that revolutionised the vacuum with cyclonic suction, restyled the hair dryer and pioneered bladeless fan technology, the Dyson CameraJet was never going to be an obvious product.

Back in May 2026, I visited Dyson’s factory and global HQ in Singapore to take a first look at the Dyson CameraJet. I went behind the scenes in Dyson’s oral health care labs where six years of research, development and engineering for the CameraJet had been taking place and spoke to Rich Bacon, head of product development at Dyson, to find out what makes the CameraJet so unique. I also asked him about the potential security implications of having a smart camera in the bathroom, and how Dyson hopes to improve our oral health.

Why now?

When I first saw the CameraJet I immediately wanted to know why Dyson is branching into attempting to make one of the best electric toothbrushes and why now?

The Dyson team said it likes to start with a problem people experience every day and ask whether they can solve it better through engineering. “Oral care is an area where many people want to improve their routines, but often struggle with consistency, technique, or understanding how effectively they're brushing,” Bacon explained. “Dyson research shows 9 in 10 people do not floss as regularly as they should, reinforcing the need for a solution that helps target the gaps between teeth as part of an everyday routine.

“The technology is now at a point where we can combine WiFi, AI, intelligent sensing and fluid dynamics with a highly engineered brushing experience, making this the right time to bring the product to market.”

By combining two devices – a toothbrush and water flosser – in one, the CameraJet has the potential to save us time in our daily routines and also help us brush for the recommended time. “In our research we found that a lot of people brush for 45 seconds, but the optimum time is for two minutes, or ideally three,’ says Bacon. ‘When I’m using this device myself for three minutes, it’s much more convenient than having separate devices to clean your teeth.”
