Plug the power cord into a standard outlet near your litter box location

The Litter Robot 4 comes with a power cord that connects to the back of the unit. Find a standard 120-volt household outlet within reach of where you plan to place the litter box — most cords are about 6 feet long, so plan your location accordingly. Plug the cord firmly into the outlet until you hear or feel a click.

The unit will not turn on when ready after plugging in. You need to complete the setup process first, which takes about 10 minutes and involves the Litter Robot app on your phone.

Key Takeaways

  • The power cord plugs into the back of the unit and connects to any standard household outlet within 6 feet of your planned location.
  • After plugging in, the unit enters setup mode and will not cycle until you complete the app setup process.
  • During setup, you will create a Wi-Fi connection between the Litter Robot 4 and your home network through the official Litter Robot app.
  • The blue light on the control panel indicates the unit is powered and ready for setup; a solid blue light means setup is complete.
  • If the unit does not respond after plugging in, check that the outlet works by plugging in another device like a lamp.

read the Litter Robot app before you plug in

Before you connect the power cord, read the official Litter Robot app to your smartphone. Search for "Litter Robot" in the Apple App Store or Google Play Store and install it. Create an account with your email address and a password you will remember — you will need this login information every time you want to check on your litter box or adjust settings.

Having the app ready before plugging in saves time and prevents confusion during the setup window. The unit enters setup mode for a limited time after power-on, and you do not want to be downloading software while the window is open.

Connect the Litter Robot 4 to your Wi-Fi network through the app

Once the unit is plugged in, open the Litter Robot app and log in with your account. Tap "Add Device" or the plus icon, depending on your app version. The app will search for nearby Litter Robot units in setup mode. When your unit appears in the list, select it.

The app will then ask you to select your home Wi-Fi network from a list and enter your Wi-Fi password. Type your password carefully — the app cannot see what you type, so mistakes here are the most common setup problem. After you enter the password, the app will connect the Litter Robot 4 to your network. This usually takes 30 to 60 seconds.

Once the connection is complete, the app will show your unit as "Online" and the blue light on the control panel will stop blinking and stay solid. At this point, setup is finished and the unit is ready to use.

What the lights and sounds mean during setup

The Litter Robot 4 has a blue light on the front control panel that tells you what is happening. When you first plug it in, the light will blink slowly — this means the unit is in setup mode and waiting for a Wi-Fi connection. While the app is connecting, the light may blink faster or change briefly. Once the connection succeeds, the light becomes solid blue and stays on.

You may also hear a short beep or series of beeps during setup. A single beep usually means the unit received power. Multiple beeps or a longer tone can mean the unit is searching for a connection or has completed setup. These sounds are normal and do not indicate a problem.

Troubleshooting when the unit does not respond after plugging in

If nothing happens after you plug in the power cord, first check that the outlet itself works. Plug in a lamp, phone charger, or another device you know works. If that device powers on, the outlet is fine and the problem is with the Litter Robot. If the outlet is dead, try a different outlet in the same room or a nearby room.

If the outlet works but the Litter Robot still does not show a blue light, unplug the cord, wait 10 seconds, and plug it back in. Sometimes the unit needs a full power cycle to start up. If it still does not respond after two attempts, the unit may have a hardware problem and you should contact Litter Robot customer support with your purchase receipt or order number.

If the blue light appears but the app cannot find the unit, make sure your phone is connected to the same Wi-Fi network you are trying to connect the Litter Robot to. The app and the unit must be on the same network to communicate. Also check that your Wi-Fi password is correct — an incorrect password is the most common reason the connection fails.

Position the outlet and cord safely away from water and pets

Choose an outlet that is not directly above or next to a water bowl, water fountain, or any place where water might splash. Litter Robot 4 is not waterproof, and water damage is not covered under warranty. If your outlet is in a damp location, consider using a short extension cord to move the plug to a drier spot.

Keep the power cord out of the path where you or your cat walk regularly. A cord that gets stepped on or chewed can become a safety hazard. If your cat tends to chew cords, use cord covers or run the cord along the wall where it is less tempting. Do not coil the cord tightly or place heavy objects on top of it, as this can damage the insulation over time.

Frequently Asked Questions

Can I use an extension cord with the Litter Robot 4?

Yes, you can use a heavy-duty extension cord rated for at least 10 amps if your outlet is too far away. Use a cord no longer than 25 feet to avoid voltage drop, which can cause the unit to malfunction. Avoid daisy-chaining multiple extension cords together.

Does the Litter Robot 4 need to stay plugged in all the time?

Yes. The unit needs constant power to cycle, monitor sensors, and connect to Wi-Fi. If you unplug it, the app will show it as offline and it will not clean the litter until you plug it back in and it reconnects to your network.

What if I do not have Wi-Fi or my Wi-Fi is not working?

The Litter Robot 4 requires Wi-Fi to set up and to send you notifications through the app. Without Wi-Fi, you can still use the unit by pressing the manual cycle button on the control panel, but you will not have remote monitoring or app features. Contact Litter Robot support if you need to set up the unit without Wi-Fi.

Is it normal for the unit to make noise right after I plug it in?

Yes. The unit may beep, whir, or make clicking sounds as it powers on and runs a startup check. These sounds usually last 10 to 30 seconds. If the noise continues for more than a minute or sounds like grinding or scraping, unplug the unit and contact customer support.

Can I plug the Litter Robot 4 into a smart plug or power strip?

You can use a power strip, but avoid smart plugs that turn off automatically or on a schedule. The Litter Robot needs constant power to function. If you use a smart plug and it cuts power, the unit will lose its Wi-Fi connection and you will need to set it up again.
