Replacing the Litter-Robot 4 Base is easy. Follow these steps to remove the old base and quickly install a new one.

1. Make sure the unit is in the Home/Ready position. Press the Power button to turn the unit off, then unplug the unit at the bottom of the base. (Do not discard the power supply.)
    

2. Remove the bonnet:

   1. Press and hold the latches on both sides of the bonnet, then lift and rotate the bonnet to its open position.
      
   2. Unlatch the center tab on the bonnet from the catch clip on the unit frame behind the robot. Set the bonnet aside.
      
      

3. Remove the globe: Grab the black handle located on top of the globe, lift the globe off the base, and set it aside.
    

4. Remove the waste drawer from the base and set it aside.
    

5. Set aside the old base to make room for the new base.
    

6. Remove the new base from the box and place it in the desired location near a power outlet. (A firm, level surface is required for accurate detection of cats and weight readings.)

7. Replace the globe: Hold the globe by the black handle and set it onto the new base. Ensure the back of the globe is sitting flush in the rear bearing pocket: The large black gear on the rear of the globe will line up with the small white gear in the base.
    

8. Replace the bonnet:

   1. Latch the center tab on the bonnet into the catch clip on the unit frame behind the robot.
      
   2. Rotate the bonnet downward over the globe and push down on the bonnet from the top to make sure it is latched and secure.
      
      

9. Slide the waste drawer into the new base.
    

10. Plug the small end of the existing power supply into the power input on the back of the base (tilt the unit forward for easier access).
     

11. Plug the AC/DC adapter into a wall outlet if it is not already.
     

12. Press the Power button on the control panel.
     

13. The new base, which has a new serial number, will need to be onboarded to the Whisker app.
    

    1. Open the Whisker app and follow the onboarding instructions. Once complete, your newly onboarded Litter-Robot 4 will appear as a new robot in the Whisker app.
    2. Delete your old robot: In the Whisker app, select your Litter-Robot 4 unit from the dashboard, tap on the Settings gear in the top right corner, tap Delete Robot, then tap Yes.
