Litter-Robot Firmware Update Instructions
In the Whisker app, select your Litter-Robot 4 unit from the dashboard.
Tap on the Settings gear in the top right corner.
On the Robot Settings page, tap Firmware Information.
On the Information page, tap Update Firmware to begin the update process.
This may take upto 30 minutes to complete. You will see a single white light blinking on your unit's control panel - this is your signal that your robot's firmware is updating.
There is no need to stand by the unit during the update.
The light bar on your robot's control panel should return to the solid blue "ready" status.
To confirm the update was successful, your app should not display the "Update Firmware" button and you should have the latest ESP, PIC and/or TOF firmware.
Visit our Whisker Firmware Updates page to find the latest and greatest updates to ensure your Litter-Robot is up-to-date and fully functional.
No. As long as your Litter-Robot 4 is connected to your home WiFi, you should be able to complete this firmware update remotely using the Whisker app. If the unit indicates that it has disconnected from WiFi after the update (solid white light below Connect (WiFi) button on robot), then simply press the Connect (WiFi) button and the solid white light should change to blinking blue and then solid blue within a few seconds. NOTE: your robot will operate normally even if not connected to WiFi—however, you will lose app access until reconnected.
If this happens, simply exit out of the app and open it again, then check the firmware version again.
If this happens, push the Connect (WiFi) button on the robot. The light under the Connect (WiFi) button will change from solid white to blinking blue, then to solid blue within a few seconds.
For users with multiple robots, please select each robot individually in the app and update accordingly.
