Litter-Robot 4: OdorTrap® installation guide

Litter-Robot 4 can be equipped with (2) OdorTrap® Packs that are installed on the outer bottom area of the globe. The packs sit directly over the waste drawer to eliminate odors.


OdorTrap® Packs are sold separately and not required for the unit to function.

  1. Press and hold the Cycle and Empty buttons on the control panel for 3 seconds, or tap “Replace Filter” under Controls in the app.
  2. A clean cycle will begin; the cycle will pause when the globe reaches the “replace filter” position.
  3. Open the bonnet: Press and hold the latches on both sides of the bonnet, then lift and rotate the bonnet to its open position to reveal the filter pocket.
  4. Open the filter cover and remove the carbon filter (if installed). Place 2 OdorTrap® Packs under the filter cover and reinstall the cover. Under normal use, 2 packs should last approximately 1 month. (Note: OdorTrap® Packs may shift as the globe rotates.)
  5. Close the bonnet: Rotate the bonnet downward over the globe and push down on the bonnet from the top to make sure it is latched and secure.
  6. Press the Cycle or Reset button to resume the clean cycle; when the clean cycle has ended, press the Reset button to zero the weight sensors.
