ROBOROCK·FAULT ERR 22 WARN
Roborock Error 22 — Dock locator dirty
Severity: Warning — robot can clean but will struggle to find its dock afterwards S5S6S7S8Q
DIRECT ANSWER
Error 22 means the dock locator sensor is blocked by dust. This is the receiver the robot uses to home in on the charging dock's signal — older manuals call it the recharge sensor. Wipe it clean and retry.

COMMON CAUSES · RANKED
1
Dust on the locator sensor MOST COMMON
A dust film over the receiver window scatters the dock's infrared signal.
2
Dirty dock signal window
The transmitter side gathers dust too. Wiping only the robot fixes half the link.
HOW TO FIX IT
No battery or electrical work involved in this fix.
Wipe the sensor on the robot
Clean the locator window on the robot body with a soft dry cloth.
Wipe the dock's signal area
Give the front face of the charging dock the same treatment.
Send the robot home
Use the dock button or the app and watch that it docks cleanly.
