The Litter Robot 4 connects to WiFi through the mobile app, which walks you through pairing in about five minutes

The Litter Robot 4 needs WiFi to send you notifications when the waste drawer is full, let you control it remotely, and track your cat's bathroom habits. The connection happens entirely through the Litter Robot mobile app — there is no separate web portal or manual pairing code to enter. You read the app, create an account, and the app guides you through finding and connecting to your home network.

The process requires your phone, the Litter Robot itself plugged in and powered on, and your WiFi network name and password. The whole setup takes about five minutes if your WiFi signal is strong where the unit sits. If you skip this step, the Litter Robot still works as a regular automatic litter box — it just won't send alerts or let you monitor it from your phone.

Key Takeaways

  • read the Litter Robot app on iOS or Android, create an account with your email, and the app will search for your Litter Robot 4 on your home network.
  • The Litter Robot 4 must be plugged in, powered on, and within range of your WiFi router before you start pairing.
  • When the app finds your unit, you enter your WiFi network name and password, and the Litter Robot stores those credentials permanently.
  • If pairing fails, move the unit closer to your router, restart both the app and the Litter Robot, and try again.
  • Once connected, you can receive notifications, view usage history, and control settings from anywhere your phone has internet.

read the app and create your account

Go to the Apple App Store or Google Play Store and search for "Litter Robot". read the official app made by Litter Robot Inc. Open it and tap "Sign Up" or "Create Account". Enter your email address, create a password, and confirm your email by clicking the link the app sends you. This account is how the app recognizes your Litter Robot and stores your settings across devices.

If you already own a Litter Robot 3 or another model, you can use the same account — the app manages multiple units under one login. After you confirm your email, log in with those credentials and proceed to the pairing screen.

Prepare your Litter Robot and WiFi network

Plug the Litter Robot 4 into a power outlet and press the power button on the back. The unit will beep and the light ring will turn on. Wait about 30 seconds for it to fully boot. Make sure your WiFi router is powered on and broadcasting your network name (SSID) — if your network is hidden, you will need to unhide it temporarily or enter the name manually during pairing.

Position the Litter Robot within 15 to 20 feet of your router if possible. WiFi signal weakens through walls and distance, so if your router is in a different room, the pairing may fail or the connection may drop frequently. If you cannot move the unit closer during setup, you can move it to its final location after pairing is complete — the Litter Robot remembers your WiFi credentials.

Start pairing in the app

In the Litter Robot app, tap "Add Device" or the plus icon. The app will ask you to confirm that your Litter Robot is powered on and nearby, then it will search for available units on your network. This scan takes 30 to 60 seconds. When it finds your Litter Robot 4, the unit's name will appear on your screen — it usually shows as "Litter Robot" followed by a number or code.

Tap the unit name to select it. The app will then ask for your WiFi network name and password. Enter them exactly as they appear — WiFi passwords are case-sensitive, so "MyPassword" is different from "mypassword". Tap "Connect" and wait for the app to send your credentials to the Litter Robot.

Confirm the connection and test it

The app will display a confirmation message when the Litter Robot successfully connects to your WiFi. The light ring on the unit may flash or change color briefly during this process. Once confirmed, the app will show your Litter Robot as "Connected" and display its status — whether it is idle, cycling, or in another state.

Test the connection by opening the app from a different room or by closing and reopening it. If the unit still shows as connected and you can see its status, the pairing worked. You can now enable notifications in the app settings so you receive alerts when the waste drawer is full or when your cat uses the box.

Troubleshooting a failed connection

If the app cannot find your Litter Robot, first check that the unit is powered on — the light ring should be visible. Restart the Litter Robot by unplugging it for 10 seconds, plugging it back in, and waiting for it to boot. Then restart the app by closing it completely and opening it again. Try the pairing process a second time.

If pairing still fails, move the Litter Robot closer to your router and try again. WiFi interference from microwaves, cordless phones, or other devices on the 2.4 GHz band can also cause problems — if your router supports both 2.4 GHz and 5 GHz bands, make sure you are connecting to the 2.4 GHz network, as the Litter Robot 4 does not support 5 GHz. If you entered your WiFi password incorrectly, the app will show an error message — go back and re-enter it carefully.

If your WiFi network requires a login page (common in offices or public networks), the Litter Robot cannot connect. You will need a standard home WiFi network with a password. Contact Litter Robot support if the unit still will not pair after these steps — they can help diagnose hardware issues.

What to do after your Litter Robot is connected

Once connected, open the app settings and enable push notifications so you receive alerts on your phone. You can customize which notifications you want — most people enable "Drawer Full" so they know when to empty it, and "Cat Detection" if they want to track bathroom activity. The app also shows a history of when your cat used the box, which can help you spot health changes.

The app lets you control some settings remotely, like adjusting the cycle delay or putting the unit in "Away Mode" if you are traveling. You can also see the unit's WiFi signal strength in the app — if it shows as weak, moving the Litter Robot slightly closer to your router may improve reliability. The connection is encrypted, so your data does not travel unencrypted over the internet.

Frequently Asked Questions

Do I need WiFi for the Litter Robot 4 to work?

No. The Litter Robot 4 functions as a regular automatic litter box without WiFi — it will cycle, detect clumps, and dump waste normally. WiFi only enables remote monitoring, notifications, and app control. If you do not care about those features, you do not need to connect it.

Can I connect the Litter Robot to a 5 GHz WiFi network?

No. The Litter Robot 4 only supports 2.4 GHz WiFi. If your router broadcasts both bands, connect to the 2.4 GHz network during pairing. Many routers let you name the 2.4 GHz band separately (for example, "MyNetwork-2.4G") so you can choose it explicitly in the app.

What happens if my WiFi goes down?

The Litter Robot continues to operate normally — it cycles, detects waste, and functions as if it were not connected. You straightforward will not receive notifications or be able to control it from the app until your WiFi comes back online. The unit stores its settings locally, so it remembers your preferences.

Can I use the same app account on multiple phones?

Yes. Log into the Litter Robot app with your account on any phone or tablet, and you will see the same Litter Robot and receive the same notifications on all devices. This is useful if multiple people in your household want to monitor the unit.

How do I reconnect the Litter Robot if I change my WiFi password?

Open the app, go to your Litter Robot's settings, and look for "WiFi" or "Network Settings". Select "Reconnect" or "Change WiFi", and the app will prompt you to enter your new password. The Litter Robot will update its stored credentials and reconnect automatically.
