Egg Sweeper

Egg Sweepers are combat blue robots deployed by Eggman in Sonic the Hedgehog 2006. It's an advanced model of the Egg Bomber. The Egg Sweeper is equipped with the same appendage to catapult explosive rounds at their enemies, is capable of moving in horizontal and vertical surfaces and has an invisibility mode. It's still easier to spot, as it has a disturbance effect around its outline. If it successfully attacks while invisible, it self-destructs for massive damage.
