The Cleansweep Eleven, manufactured by the Cleansweep Broom Company, was released in 1995 [Y15], making it the latest broomstick in the series. Ron Weasley received one as a reward upon being made a prefect (OP9).
He was very happy about it, so we know a fair bit about its specifications from him:
- It can go from nought to seventy in ten seconds (OP9). This is presumably in miles per hour, as broomstick speeds are typically expressed that way (QA9).
- The handle is made of Spanish oak (OP9). Note that oak is a wand wood (PS5).
- It features anti-jinx varnish and in-built vibration control (OP9).
