Litter-Robot 5 & Pro: Offline

If your Litter-Robot 5 or Litter-Robot 5 Pro has already been onboarded to the Whisker app but has lost connection, you may see a blinking yellow light on the Control Panel and an LCD message that reads  "Disconnected.” This means the unit is no longer connected to your WiFi network and is attempting to reconnect.

Quick links

Understanding the WiFi Disconnected state

• The LED Indicator Light blinks yellow.
  • On Litter-Robot 5 Pro models, the camera LED light will also blink yellow.
• The LCD screen displays:
  
  Disconnected
  Reconnecting, check router, or update network in app.
  
  
• The robot will automatically attempt to reconnect using the last saved network credentials. If reconnection fails after several minutes, manual reconnection may be required.

Before you begin

• Verify that your home WiFi network is active and stable.
• Confirm other devices can connect to the same network.
• Ensure your router is within range of the Litter-Robot.
• Keep your phone nearby with bluetooth enabled (does not apply to Litter-Robot 5 Pro models) and the Whisker app installed.
  

  Note: If your router or WiFi credentials have changed, you’ll need to update them in the app.

Check your WiFi network

• Make sure your internet connection is working.
• Confirm your network name (SSID) and password haven’t changed.
• If you use both 2.4 GHz and 5 GHz bands, remember:
  • Litter-Robot 5 Pro supports both 2.4 GHz and 5 GHz.
  • Litter-Robot 5 (standard) connects to 2.4 GHz only.
• Reboot your router if the signal seems unstable.
• Move the unit closer to the router during reconnection attempts.

Reconnect your Litter-Robot 5

When the unit displays Disconnected, the robot automatically begins a reconnect attempt.

• The LCD shows “Disconnected” for roughly 5 seconds. 
• The screen then updates to “Reconnecting, check router or update network in app” for about 10 seconds while the robot attempts to re-establish connection.
• If reconnection succeeds, the LED Indicator Light turns solid white and the LCD returns to the Home screen.
• If the reconnect cycle repeats or the yellow blink persists, continue to the next section to verify network details or update WiFi settings through the Whisker app.

Confirm successful reconnection

• When connection is restored, the LED Indicator Light will be solid white.
• Open the Whisker app and confirm your Litter-Robot shows Online.
• Send a manual Cycle command in the app to ensure communication is active.
• Tap your device → Controls → Cycle.

Success: Your Litter-Robot 5 performs a cycle and returns to Home with a solid white light.

Unsuccessful: You will receive an “Offline” notification on the Whisker app screen. Continue to the next steps.

Update or change your network (if needed)

• If you’ve recently changed routers, SSIDs, or passwords:
• Open the Whisker app.
• Tap your device → Device Settings → Update Network.
• Follow the prompts to onboard the robot to your new network.
• Once complete, confirm the LED is solid white and the app shows the robot online.

Network tips

• Litter-Robot 5 Pro supports both 2.4 GHz and 5 GHz Wi-Fi.
• Use 5 GHz for faster camera performance and lower latency.
• Use 2.4 GHz if your robot is far from the router or the signal is weak.
• Litter-Robot 5 (standard) connects to 2.4 GHz only.
