  • How do you install the waste drawer liner in Litter-Robot 3?

    It’s easy! Open a new waste drawer liner and roll down the edges about four times. Start at the back of the waste drawer and push the rolled edge of the bag into each of the four tabs, keeping the bag taut as you work forward. Make sure the bag is taut across the back and sides, then pull the slack forward toward the carbon filter. Tip: Make sure the bag does not come up past the top of the sides of the waste drawer. You want to make sure the bag sits below the edges, so it cannot be seen by the Drawer Full Indicator lenses and potentially report a false flashing blue Drawer Full Indicator light on the control panel. 

  • How do you install the waste drawer liner in Litter-Robot 4?

    Simply open a new waste drawer liner and wrap the edges over the rim of the waste drawer. Push the remainder of the bag into the bottom of the waste drawer and then slide the waste drawer closed. Press the Reset button to zero the weight sensors. Download the installation guide.

  • How often do I need to replace the Litter-Robot waste drawer liner?

    Whenever you need to empty the waste drawer. That'll depend 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 should be fine.
  • Do the liners work with any Litter-Robot model?

    Yes! The liners fit perfectly in the waste drawer of any Litter-Robot 4, Litter-Robot 3 (with or without Connect), or Litter-Robot 2.

  • Can I use any type of bag in the waste drawer?

    Yes, you can use any bag that fits in the waste drawer. However, please note that waste level readings may be inaccurate when using a dark bag, especially when the drawer is empty. As clumps start to collect in the drawer, the readings will become more accurate. For the most precise waste drawer readings and a seamless experience, we highly recommend using Litter-Robot Waste Liners.

Easy to install

Just wrap the edges of the liner over the rim of your Litter-Robot 4 waste drawer, or push the rolled edges of the liner into each of the four tabs in your Litter-Robot 3 waste drawer.
