Sweeper (スイープ Suīpu?, lit. "Sweep") is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, pond skater-based Badnik model created by Dr. Eggman that is designed to glide along water surfaces.
Physically, Sweepers resemble pond skaters. These robots have elongated, mechanical legs connected between their only head and torso. They also have a pair of eyes, a small gray needle nose and a red-glowing siren on their head.
First appearing in Sonic Adventure and Sonic Adventure DX: Director's Cut, Sweepers appear only in Sonic's version of Emerald Coast and Twinkle Park. In gameplay, they simply skim along the surface of water sections, but if the player gets close, they will approach Sonic and attack with their pointy noses. The player can easily defeat them using the Spin Jump or Homing Attack.
In the Nintendo 3DS version of Sonic Generations, Sweepers are encountered in Emerald Coast again. Like in Sonic Adventure, they are skimming across local water sections. In this game, they are not likely to attack the player, as they serve more as obstacles in the stage. The player can easily defeat them using the Homing Attack or Boost.
In Emerald Coast Act 1, they appear over the water area in the final section of the stage. In Act 2, they are encountered halfway through the stage.
Powers and abilities
The Sweepers can skim across water surfaces quickly. They also has a sharp nose that is perfect for skewering their foes.
