Locations and Farming Routes for Subdetection Units in Genshin Impact
The Subdetection Unit was introduced in Genshin Impact 4.1 and is not found in the initial area of Fontaine. Like other local specialties, the Subdetection Unit respawns every 48 hours. There are over 70 of them scattered throughout the game world, so players will need to embark on at least three farming trips to gather the 168 items required for a single character.
Use Elemental Sight to ease the process of locating the small robotic bug.
Liffey Region Route
For the Liffey Region Route, follow this direction:
Start at the Statue of the Seven and locate four Subdetection Units within the vicinity. There is no need to descend the stairs, as all of them are conveniently situated on the same level as the Statue of the Seven.
Utilize the Teleport Waypoint to the north of Mont Esus East and proceed in a northerly direction towards the tower where the quest "In Search of Lost Time" can be initiated. Two Subdetection Units can be found near the stairs in front of the towering structure, while the remaining two are situated behind the tower. Proceed to the outermost section of the building, and you will find them in close proximity to a red camera, a shovel, and a bag.
Return to the Teleport Waypoint and head southeast. Make your way to the small island where you will find a Subdetection Unit near Genshin Impact Lumitoile.
Afterwards, cross the water and collect two of the local specialties that are floating near a torch. Proceed to climb up the cliff to reach the small ruins where you can obtain two additional Subdetection Units. One can be found near a table and some books, and the other is located across from it, hovering near a stack of books.

One of these can be found near the stairs leading to the building, another is in close proximity to the stairs by the door, and the third one is positioned at the side of the building, accessible by climbing the wooden ladder.
For the upcoming route, employ the Waypoint in a southerly direction and obtain two Subdetection Units near the bridge. One of them is concealed behind a breakable object adjacent to the wall, while the second one can be found at the end of the bridge. Afterward, proceed eastward to acquire a robot beetle situated at the bottom of the hill.
