'What you have there is essentially a $70,000 piece of lab equipment in a handheld consumer product': Jake Dyson shares the design secrets of the brand's new mouthwash-squirting toothbrush — and the company explains why some early models had problems

Dyson is known for doing the unexpected, and nothing in the brand's history has been quite as unexpected as its recent toothbrush launch.

Well... perhaps the air-purifying headphones were more of a surprise.

But still, this shift into oral care certainly wasn't on my 2026 bingo card.

The Dyson CameraJet launched earlier this month.

A toothbrush like no other, this chunky device made headlines with its integrated camera and gap-targeting mouthwash squirter.

However, the launch has been dogged somewhat by multiple reports of new gadget breaking almost immediately.

The toothbrush is also showing as out of stock in multiple territories, including the US, UK and Australia.

Dyson has issued a response, which reads: "We have had a very positive reaction to the new Dyson CameraJet and are experiencing strong demand globally.

We are seeing some shortages of supply as we are in the process of scaling up production.

Additionally, we are aware that a small number of early batches of Dyson CameraJet products may have experienced a component issue.

We are isolating those batches and are taking all the necessary steps to support our customers." Rocky start aside, it's an impressive piece of engineering, and assuming Dyson gets those problems fixed, it has plenty going for it (our tester was impressed enough to award it four stars in our Dyson CameraJet review ).

I got a demo at the Dyson Unveiled event, where I also had a chance to chat to Jake Dyson — Chief Engineer at the brand, and son of founder James — about the new product's development process.

Here are seven interesting things I learned about the new CameraJet...

For avoidance of confusion, I'll use 'Jake' to mean the person, and 'Dyson' when I'm referring to the brand.
