The Court Cleaner is a secondary weapon for the Gunner class in Blitz Brigade. It is a circular cannon that shoots really bouncy tennis balls. The tennis balls are explosive, and will detonate automatically when making immediate contact with an opponent or a vehicle, or will detonate manually after a short period of time. This weapon is known to be "easy to learn, hard to master". It is hard to predict where the tennis balls will bounce off to, so this weapon is difficult to aim when trying to kill a moving opponent.
- This weapon, like Zeus's Razor, Frostwork and Whirlwind, can bypass its normally slow rate of fire if the trigger button is tapped many times in rapid succession ("spam-fired").
