Flashing red lights on your Shark Ion? Decode the blink patterns for Clean, Dock, and Max lights to find the exact fix for your model.
Your Shark Ion Robot speaks to you, but it doesn’t use words—it uses lights. When it stops in the middle of a room and starts beeping or flashing, it’s trying to tell you exactly what is wrong.

|---|---|---|
| All Lights Off | Battery is Dead or Power Switch Off | Flip the side power switch to “I” (On). Place robot on dock manually. |

Common “Tricky” Codes Explained
1. The “Cliff Sensor” Error
If your robot backs up and spins in circles or refuses to go over dark rugs, it’s a Cliff Sensor issue.
- The Cause: Dust covers the sensors, or the robot thinks a black carpet is a “cliff” (stairs).
- The Fix: Wipe the sensors with a dry cloth.
2. The “Wheel Wedge” Error
If the lights flash and the robot beeps 3 times, a drive wheel is likely wedged.
- The Cause: It drove over a sock or toy that is now jammed between the wheel and the housing.
- The Fix: Push the wheels up and down manually to dislodge the object.
3. The “Wi-Fi” Reset
If the blue Wi-Fi light is blinking slowly, it is in pairing mode. If it is red or off, it has lost connection.
- The Fix: Hold
