Martin Bremner from Partridge Green was given a TV challenge to make a cleaner out of junk.
With colleagues, he went to Los Angeles and his invention succeeded when it started to pick up rubbish from the streets.
A normal cleaner costs up to £20,000 but this one was built free from scrap found in a yard.
Perhaps now he will donate it to Brighton and Hove, which needs all the help it can get with street sweeping.
