Right and Left Cliff Sensors for Roborock S8 MaxV ultra Qrevo Slim

Restore safe stair and drop-off detection on your Roborock S8 MaxV Ultra or Qrevo Slim with these direct-replacement Left and Right Cliff Sensors. Cliff sensors are an essential safety feature — they detect elevated edges such as stairs and prevent your robot from falling. A faulty cliff sensor can cause the robot to halt unexpectedly, avoid certain floor areas, or fail to detect a real drop-off. Replace them as a pair and restore confident, safe navigation throughout your home.
