Ongoing Maintenance 
Empty the Waste Drawer when indicated by the 
flashing blue light on the Control Panel. 
How often you will need to empty the Waste drawer 
depends on the number and size of your cats. For two 
average-sized cats, twice per week is typical. For a single 
cat, once per week is usually sufficient. 
Pull out the Waste Drawer using the handle below the 
step, then gather the edges of the liner bag and dispose.  
You can use Litter-Robot custom-fit, biodegradable Waste 
Drawer liners or any 10-13-gallon trash bags. 
To install a new drawer liner, open the bag and roll down 
the edge about four times. Starting at the back of the 
drawer, push the rolled edge of the bag into each of the 
four tabs, keeping the bag taut as you work forward. 
Slide the drawer back in, being careful not to push the 
unit against the wall or into a corner (must not be 
touching any walls). Then, press the Reset button to 
reset the Cat Sensor.  
Add litter as needed. 
Check the litter level once per week or each time you 
empty the Waste Drawer. Add just enough litter to meet 
the raised Fill Line inside the Globe, and be careful not to 
overfill it. After adding or removing litter, press the Reset 
button to reset the Cat Sensor.  
Press the Reset button. 
Any time you affect the weight or placement of the unit 
(including emptying the Waste Drawer, adding or 
removing litter, or cleaning or moving the unit), press the 
Reset button to ensure the Cat Sensor will detect your 
cat and cycle properly.
