Seventy miles per hour
The Cleansweep Eleven was a broomstick produced by the Cleansweep Broom Company in or before 1995. The broom was made of Spanish oak, with anti-jinx varnish and a built-in vibration control feature. It could accelerate from naught to seventy miles per hour in ten seconds.
- In the summer of 1995, Ron Weasley was given a Cleansweep Eleven as a present from his parents for becoming a Prefect (although the price made Mrs. Weasley hesitate slightly deciding whether to buy it or not), and used it when he played as Keeper for the Gryffindor Quidditch team. Ron won two Hogwarts Quidditch Cups with his Cleansweep Eleven.
