2.2 Placement

Place the Litter-Robot 4 on a firm, level surface. Avoid carpeting or uneven surfaces, as this can affect the accuracy of the weight scale technology. Ensure there is enough space around the unit for proper operation and access to the waste drawer.

2.3 Power Connection

Connect the power adapter to the Litter-Robot 4 and plug it into a wall outlet. The unit will perform an initial cycle upon power-up.

2.4 Litter Filling

Fill the globe with clumping cat litter up to the indicated fill line. The Litter-Robot 4 is compatible with any clumping litter. Avoid using non-clumping, pine, corncob, or crystalline litters as they may not function correctly with the sifting mechanism.

2.5 Whisker App Setup

Download the Whisker app from your device's app store. Follow the in-app instructions to connect your Litter-Robot 4 to your home Wi-Fi network. The app allows you to monitor litter box activity, track cat weight, and adjust settings.

3. Operating Instructions

3.1 Automatic Cycle

The Litter-Robot 4 automatically initiates a cleaning cycle a few minutes after your cat exits the globe. The patented sifting process separates waste, which is then deposited into the waste drawer below.

• Sleep Mode: Activate sleep mode to prevent cycles during specific hours, such as overnight.
• Panel Lockout: Lock the control panel on the unit to prevent accidental button presses.

4. Maintenance

4.1 Emptying the Waste Drawer

The Whisker app will notify you when the waste drawer is full. To empty, pull out the waste drawer from the base of the unit. Secure the waste liner and dispose of it. Replace with a new waste liner.

4.2 Replacing Waste Drawer Liners

The Litter-Robot 4 uses standard kitchen trash bags (10-13 gallon) as waste liners. Simply fit the new bag into the waste drawer, ensuring it covers the bottom and sides.

4.3 Replacing Carbon Filters

Carbon filters should be replaced approximately once a month, or more frequently if odors persist. To replace, open the bonnet of the Litter-Robot 4, locate the filter compartment, remove the old filter, and insert a new one. Ensure the compartment is securely closed.

4.4 Cleaning the Unit

For thorough cleaning, it is recommended to periodically wipe down the interior and exterior of the globe and base. Use the provided cleaner wipes or a pet-safe cleaning solution. Avoid harsh chemicals or abrasive materials.

5. Troubleshooting

5.1 Common Issues and Solutions
