Cleaners

Biffy: “You're so dead if you don't make it back before detention's over,”

Lee: “I'm also dead if these cleaner freaks catch me so tell me something I don't know!,”

—Lee speaks to Biffy whilst the hazmats chase him (From Blitkrieg Bop'd)

White Hazmats Also nicknamed "cleaner freaks" by Lee Ping, and "The Crazy Cleaner Peoples" by Holger Holgaart the Cleaners are the new janitorial staff of A Nigma High following the inauguration of Principal General Barrage. The white cleaners are revealed to be robots in School Hard and can be considered to be tertiary antagonists in the series. Their human counterparts are the Green Hazmats.

Throughout most of Seasons 1 and 2 they work for Barrage, but later in season 2 a chip implanted in the Cleaners causes them to fall under the control of Victoria and Lynch Webber.

Personality

Despite being robots, they do seem to have some intelligence, and enjoy working for Barrage. White Cleaners seem to enjoy goofing off while they should be doing their work, they are capable of joy in doing their job and seem to have a certain theatrical side especially with fireworks and explosions. One has even shown to have felt disappointment when Barrage chose 3 other Cleaners to help him but, brushed him off.

History

The Cleaners, as implied by their name, are the new janitorial staff at A. Nigma High. More importantly they act as secret police for Barrage obeying his orders dutifully and without mercy, to the point where Barrage has a remote to call the Cleaners to his position on a moments notice.

Early in the series they are constantly dressed in their gear and speak an indistinguishable language, both of which strongly imply they are not even human. (though some believed that their suits were simply a uniform which made it difficult to  understand them) In the Episode Double Date it is revealed that at least some of the Green Cleaners are humans; however in School Hard all of Barrage's white cleaners are shown to be robots. They seem to be an extension of Mann, Wurst and Finnwich.

Their responsibillities seem to extend beyond simple cleaning, during football try-outs Barrage had them removing those that failed from the field with an oversized super vacuum. They have been seen being able to reattach a side mirror to a car. Three of them were used to set up special effects for the school play, with a fourth one looking rather sad that it did not get called.

They also seem to have contracts outside the school as made evident by their presence at Brandy's apartment building, though they simply may have been chasing after the The Red Tazelwurm which was loose in the building at the time. They also work in the laboratory under the school, the center of the Prank conspiracy, as such it can be assumed that they are involved in The Prank conspiracy to some degree.

On a few occasions they have used exaggerated equipment in the use of their duties, such as oversize super vacuums, super-soakers loaded with disinfectant and as of the second season crystallizing ray guns. They have also been shown using normal cleaning equipment such as feather dusters and glass cleaner.

On one occasion they have used electric collars. The collars presumably would have been used on the Red Tazelwurm but the cleaners seemed perfectly intent on using them on Lee Ping, Tina Kwee and Lynch Webber. Schematics of these cleaners were found underneath the school on Dr. Alfred Ping's (Lee's father's) desk, suggesting that he created them or at least that he created their suits ("The Tag Along").

Green Hazmats

The Green Hazmats are the human counterparts to the robotic white ones, who seem to be employeed do to some expertise. Their are slight differences in their uniform.

Trivia

• The cleaners act as a simple EMP, as they can disrupt the connection between Lee and Biffy. This was shown multiple times throughout the first episode.
• For unknown reasons during Friday Nights Bites a group of Cleaners helped a security guard at Brandy's building chase down Holger and the reason why is unclear it may just have been that thy weren't doing anything else.
• In the unnaired pilot, the Cleaners had on Yellow suits with Blue stripes, adn their uniforms looked more suited for biohazardous disposal.
• In Serpent Strike, they are seen again and Cam says "We're going to do that things where you chase me gain arn't we?" Refering to other times in the series like in Clogspiracy where they have chased him.
