Eight-year-old inventor Sam has had his double-headed broom named as one of the UK's top 15 inventions of the last decade.
He was just three years old when he came up with the idea for a broom with two brushes.
It has one that collects the big bits of dirt and one that gets the little bits left behind - so cleaning up is less work!
The broom has even been patented, which means that no one else is allowed to copy the idea.
Now if you watch Newsround then you must be a pretty bright spark, so we want to know - what have YOU invented? Or what invention would you like to see?

"In the passenger seat of cars they should have steering wheels and pedals. So if the person driving is tired, you could just take the key out of the ignition on the right-hand side and put it into the left-hand side, so you wouldn't need to get out of the car."

"A pencil case that is a robot. When you say 'pencil', a pencil appears. You would never have to worry about leaving your stationery at home. It would come in different styles and colours. There would be a special pen so if didn't know what to write, the pen would write for you and you would get a good grade. It would have a computer fitted inside it so you can search the web for help with your work. It would make life easier because you could just tell it what you want and it would appear."

"My invention is a nail painter that paints five nails at once. All the user has to do is pick the colour of nail varnish for each brush. It is a quick and easy way to paint your nails and I bet every girl wishes they could have one."

"Well I think that my invention would be hover shoes. I read that jets are powered by the escaping of gas. So I think that these hover shoes would be attached to a sort of vacuum that pushes air into the shoes, and it would escape from four cup-like shapes at the bottom of each shoe. I personally think this is a good idea, but the only problem is you wouldn't be able to go very far with the vacuum."
