"Just caught her! She says she'll get the Cleansweep if she can."
-- Ron Weasley (OP9)
The Cleansweep Broom Company, started in 1926 by Bob, Bill and Barnaby Ollerton, produces a series of sport broomsticks. The Ollerton brothers produced large numbers of Cleansweeps aimed specifically at the racing and Quidditch markets.
The Cleansweep series are known for their ability to turn corners quickly and efficiently. Models released by the company include: Cleansweep 1, Cleansweep 2, Cleansweep 3, Cleansweep 5, Cleansweep 6, Cleansweep 7 and Cleansweep 11 (QA9).
In popular use, a "clean sweep" is a complete win over the opposition - sweeping the board clean.
