Works for Roborock robot vacuums (S, Q, Saros and Qrevo series).

Short answerRed light. The red light is on the dock, not the robot.

What it means: The light on a wash and fill dock stays red because the dock has a problem with its tanks, bin or power.

Quick fix: Check that your local voltage meets the requirement printed on the dock.
