Litter-Robot 4
If your Litter-Robot 4 is not on the most current firmware
version it should automatically update once the firmware
version becomes available for your unit. Firmware can also
be manually updated through the Whisker app.
Follow these steps to update your Litter-Robot's
firmware:
1
In the Whisker app, select your Litter-Robot 4 unit from the dashboard.
2
Tap on the Settings gear in the top right corner.
3
On the Robot Settings page, tap Firmware Information.
4
On the Firmware Updates page, tap Update
to begin the update process.
This may
take up to 15 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.
5
The light bar on your robot's control panel should return to the solid blue "ready" status.
6
To confirm the update was successful, your app should not display the "Update" button and you should have the latest ESP, PIC and/or TOF firmware.
Note: Your robot may turn off its WiFi chip after completing the firmware update. If you see a white light with the Connect (WiFi) button, simply press it once to turn the robot's WiFi back on.
Litter-Robot 5 / Pro and Litter-Robot EVO
If your Litter-Robot is not on the most current
firmware version it should automatically update once
the firmware version becomes available for your
unit.
Checking the firmware version

Once the firmware update is complete
Litter-Robot will automatically power on and off. The LED indicator light should remain solid white.

FAQ
What's new in this update?
Visit our Whisker Software Releases page to learn about the latest and greatest updates for your Litter-Robot and Whisker mobile app.
Do I need to be home to push this update to my
Litter-Robot 4?
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, follow
these steps:
Simply press the
Connect (WiFi) button and the solid white light
should change to blinking blue and then solid blue
within a few seconds. If this is unsuccessful, you
can update your network in the Whisker app. Select
your device → Settings
→ Update Network
Note: Your robot will operate normally even if not connected to WiFi — however, you will lose app access until reconnected.
Can I use my Litter-Robot while it’s
updating?
No. The robot should remain plugged in and idle until the firmware update finishes. Using or powering off the unit during an update can interrupt the process.
Will my app show progress during the update?
Yes. The Whisker app will display that a firmware update is in progress. Once complete, the status will change back to “Ready,” and your robot’s firmware version will be current.
What happens if my app is still updating after
30 minutes?
If this happens, simply exit out of the app
and open it again, then check the firmware
version again. If it still appears
unresponsive, unplug the unit for 60
seconds, then plug back in.
If
the issue persists, contact
Whisker Customer Experience— our team can check whether the
update completed successfully or help reset
the unit.
Please note that if you have a Litter-Robot 5 Pro model this process may take up to 30 minutes due to the built-in camera (which requires a separate update). This is normal. Do not unplug or power off your robot during this time.
My robot's WiFi turned off (single white
light below Connect (WiFi) button). How do I
turn it back on?
For Litter-Robot 4: 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 Litter-Robot 5 / Pro and Litter-Robot EVO: Press the Connect (WiFi) button for three seconds. The Connect (WiFi) button will begin blinking blue, then change to solid white once reconnected.
What if I have more than one robot?
For users with multiple robots, please select each robot individually in the app and update accordingly.
