Installing Waste Drawer Liners
The Litter-Robot 4 ships with a Waste Drawer Liner installed. These liners are made specifically for the Litter-Robot 4, but any 30-49L trash bag will also work.
1. Open a new Waste Drawer Liner or bag.
2. Wrap the edges of the Waste Drawer Liner or bag over the flange of the Waste Drawer.
3. Push the remainder of the bag into the bottom of the Waste Drawer and then slide the Waste Drawer shut.

Carbon Filter
The Litter-Robot 4 is equipped with a flexible Carbon Filter pad that is installed on the outer bottom area of the Globe. This filter sits directly over the Waste Drawer to absorb odors. The Carbon Filter is easily removed and installed by starting a Clean Cycle, then opening the Bonnet when the Globe is at the Dump Position. Replace the Carbon Filter as needed. Under normal use, one filter should last approximately 1 month. The Carbon Filter is not required for the unit to function. Replacement Carbon Filters and other odor-absorbing accessories can be ordered at

Base Seal Strips
The Litter-Robot 4 is equipped with brush-type Seal Strips on both the top and bottom of the Base. These Seal Strips help contain odors within the Waste Drawer. Replace the Seal Strips when you notice they are worn flat or peeling up. Make Seal Strips last longer by trimming loose edges between replacements. Be careful not to get them wet when cleaning the Base or they may begin to peel. Replacement Seal Strips can be ordered at 
Emptying the Litter-Robot
1. Press the Empty button to cycle the Globe clockwise, which will allow the litter to fall through the Waste Port and into the Waste Drawer for easy disposal.
2. If litter remains in the Globe, sweep the granules toward the Waste Port.
3. Press any button to return the Globe to the Home position.

IMPORTANT: Supervise and prevent your cat from entering during the Empty cycle, as the unit may not detect your cat without litter in it
