Willo is a robot that wants to replace your toothbrush

If you think about it, the basic concept of a toothbrush hasn't evolved since" forever. Sure, many people have switched to an electric toothbrush, but it remains a stick with a brush at the end.

Willo thinks that's not good enough. The company has developed an oral care device to improve brushing with a focus on plaque. The company says that basic brushing only cleans 42 percent of dental plaque, while electric brushes clean 46 percent of dental plaque.

The startup has worked with actual dentists to design its product. It still sounds a bit mysterious as the company isn't sharing much about the product. The photo is the only image of the product right now.

But what we know is that the startup has raised a $7.5 million funding round led by Kleiner Perkins, with Bpifrance and Nest co-founder Matt Rogers also participating. The company has been founded by Hugo de Gentile, Ilan Abehassera and Jean-Marie de Gentile, and it attended The Refiners accelerator program.

Now let's see how it actually works, how much it costs and if people are willing to change everything about the way they brush their teeth.
