Every Quidditch team in Great Britain (formerly)
The Cleansweep One was the first broomstick produced by the Cleansweep Broom Company. The first racing broom designed for sporting use, the Cleansweep One cornered like no other broom made. Within a year of its release, every Quidditch team in Britain was mounted on them.
