Litter-Robot 4: Ongoing Maintenance


Empty the Waste Drawer

Empty the Waste Drawer when indicated by the Light Bar flashing blue 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. 

 

  1. Pull out the Waste Drawer, gather the edges of the liner bag, and dispose. 
  2. To install a new Waste Drawer Liner, open the bag and wrap the opening over the perimeter of the Waste Drawer flange. 
  3. Push the remainder of the bag into the bottom of the Waste Drawer. 
  4. Slide the drawer back in, being careful not to push the unit against the wall or into a corner (should not be touching any walls for accurate weight measurements). 
  5. Press the Reset button to zero the Weight Sensors.
     

You can use Litter-Robot custom-fit Waste Drawer Liners or any 8-13-gallon (30-49L) trash bags. 


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 MAX Fill Line inside the Globe, and be careful not to overfill it to avoid wasting litter. After adding or removing litter, press the Reset button to zero the Weight Sensors.
 

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), to ensure the Weight Sensors will detect your cat and cycle properly.
