An A-LT Utility Droid
Custodial droids, also known as cleaning droids, were a type of droid designed for the purpose of maintaining a clean environment. During the Galactic Empire's rule, one cleaning droid was used to clean the viewports of certain residences on Level 3204, notably including the residence of Anandra Milon's family.
Demolition infiltrator droids had the ability to pose as sweeper droids when conducting secret missions. Aboard the starship called Legacy Run, custodial droids were employed for performing smaller duties. Hedda Casset took notice of one such droid not long before the ship was destroyed.
The novel The High Republic: Light of the Jedi, published in 2021, featured custodial droids. An earlier version of an excerpt from the novel used "custodiodroid" as the term.
