Litter-Robot 4: Septum Installation Guide

The Litter-Robot 4 Septum holds the sifted litter during a clean cycle. Learn how to remove and install the septum here.

You will need:

  • Phillips-head screwdriver
  1. Make sure the unit is in the Home/Ready position. Press the Power button to turn the unit off, then unplug the unit.

  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 bonnet, remove it, and set aside.

  3. Standing behind the unit, look down at the top of the globe. Remove the seven (7) screws holding the septum in place using a Phillips-head screwdriver:

    1. One (1) screw in front of the handle, near the front of the globe
    2. Four (4) screws around the waste port
    3. One (1) screw to the far left of the waste port
