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 time of the Galactic Empire's rule, one cleaning droid was used to clean the windows of some residences located on Level 3204, which included the apartment that belonged to the family of Anandra Milon.
Infiltrator demolition droids had the ability to use disguises and appear as sweeper droids to conduct secret missions. On the starship called Legacy Run, custodial droids were employed to carry out smaller tasks. A short time before the destruction of her ship, Hedda Casset took notice of one of these droids.
In the 2021 novel The High Republic: Light of the Jedi, custodial droids make an appearance. In an earlier version of an excerpt from the novel, the term "custodiodroid" was used.
