The Sweeper is one of the Racing Drones inventions: it's designed to "sweep" up cars and dissasemble them to capture drivers and potentially retrieve accelechargers. It was built as the Racing Drones' solution to get the Accede chargers won by Dr. Tezla's Drivers in Racing Realms. The only 2 drivers who have been "swept up" were Nolo and Monkey in the Metro Realm. It also has two mini vehicles that it can dispatch to deal with the Drivers; the Sweeper Drones built the "RD-W1" units to get underneath the Metal Maniac and Teku cars to sabotage them or disable them for sweeping, and the Drone motorcycle in order to race if the Sweeper is unable to. Due to the titanic size and mass of the Sweeper, it can survive a large amount of punishment from the outside to a degree, but it can be out-maneuvered by driving along narrow paths (or rushing past it from in front---if there's enough room), where it will either trap itself or fall off the course, as seen in the Neon Pipeline and Cliffside Realms respectively. In the Cosmic Realm, Monkey willingly drives his car into a Sweeper in order to hijack it and allow the other Drivers to use it as a "Trojan Horse" to get into the Drone Headquarters and rescue Mark Wylde. After leaving the Drone Headquarters by way of E.D.R. on Porkchop's Piledriver, the Drivers take another Sweeper (Which Porkchop likens to "Old Smokey") inside of the Acceledrome to leave before it's destroyed by Gig to kill the last of the Racing Drones inside.
- Even though they are massive in size, they can be taken out as easily as a RD-S1 car
- It is unknown of what would happen if a Racer was trapped inside the Sweeper after his/her car was dismantled, but probably taken to the Drones HeadQuarters to be transformed into a cyborg like Kadeem was.
- There is at least 1-3 Sweepers in each realm the Racing Drones are in after the Metro Realm.
- No Sweeper that isn't taken over by the racers survives a realm.
- Even though they were created to sweep vehicles, the Silencerz and the racers had already found a way to evade and destroy them from the Junk Realm.
- They are constantly hitting themselves in the realms in an effort to capture drivers, unintentionally causing their own destruction, similar to RD-S1 and other drones.
