Litter-Robot Cleaning Tips To Keep It Smelling Like New

Est. read time: 4 min.

In just a few minutes here and there, you can make sure your Litter-Robot stays in top shape—which means litter box scooping stays off your to-do list for good! 

Keep your Litter-Robot working (and smelling) like new with these four Litter-Robot cleaning tips:

replacing Litter-Robot 3 Connect waste drawer liner

1. Empty the waste drawer when indicated

Infrared emitters and sensors detect the level of waste in the drawer, and the blue light on the control panel flashes when it's time to empty. If you have alerts set through the Whisker app, you’ll also be notified on your phone when the drawer is full. For one average-sized cat, you'll need to empty the waste drawer about once per week, and for two cats, twice every 7-10 days is typical.

To change the drawer liner in Litter-Robot 3 (with or without Connect), simply pull out the drawer, unhook the edges of the liner, and dispose. Then, install a new drawer liner (like our custom-fit drawer liners) by rolling the edges a few times and pushing them into the four tabs (keeping the bag taut at the back). View the Litter-Robot 3 Waste Drawer Liner Installation Video.

To change the drawer liner in Litter-Robot 4, pull out the drawer and dispose of the soiled liner. 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. Check out the Litter-Robot 4 Waste Drawer Liner Installation Guide.

Any time you affect the weight or placement of the unit (by removing waste, adding litter, cleaning, or moving the unit), press the Reset button to ensure proper function. Press the Reset button when the unit is at the Home position and the control panel displays a solid blue light.

After you change the waste drawer liner and push the drawer back into the base, make sure you haven't pushed the unit against a wall or into a corner. Litter-Robot must not be touching any walls for the cat sensor to detect your cat and cycle properly.

2. Add litter as needed

Each time you empty the waste drawer, check the globe and add cat litter as needed. Add just enough litter to meet the raised fill line on the black rubber liner, but be careful not to overfill the globe. Any clumping cat litter will work with Litter-Robot, though we recommend a high-quality, clay-clumping cat litter.

Don't forget to press the Reset button when you're done adding litter.

Litter-Robot 3 carbon filter replacement

3. Replace the carbon filter or OdorTrap™ Packs periodically

Keep Litter-Robot smelling fresh by trapping unpleasant odors in the waste drawer with replacement Litter-Robot 3 Carbon Filters and Litter-Robot 4 Carbon Filters. How frequently you'll need to replace the filter is up to you (and the number of cats you have); we recommend changing the carbon filter every month for best results. See the Litter-Robot 3 Carbon Filter Installation Guide or Litter-Robot 4 Carbon Filter Installation Guide.

Litter-Robot 4 OdorTrap Pack replacement

Alternatively (or in addition to a carbon filter), add OdorTrap™ to eliminate litter box odors. OdorTrap™ uses a blend of plant-based oils to destroy litter box odors with natural chemistry. Simply place OdorTrap™ Packs in your Litter-Robot 4 filter pocket (see installation guide) or Litter-Robot 3 waste drawer near the carbon filter. We recommend replacing one pack every two weeks or two packs every month. 

cleaning Litter-Robot 4 with all-natural wipes

4. Keep it clean!

Once every month or so (depending on how frequently the unit is used), give your Litter-Robot a wipe down. A couple times per year, give it a more thorough cleaning.

For a simple cleaning, empty all of the litter from the globe by pressing the Empty button. The globe will rotate in the opposite direction of a clean cycle, allowing the litter to fall through the waste port, into the drawer. Use an unscented, enzyme-based cleaning spray or cleaning wipes to remove organic material, stains, and odors on the globe, then let it dry completely.

The base contains the cat sensor and electronics, so never submerge or soak the base—and never use bleach to clean it. Wipe down surfaces with an enzyme-based cleaner or a cloth dampened with disinfectant. If you use a spray, spray it directly onto a cloth or paper towel away from the base, so the disinfectant doesn't get into the electronics.

Litter-Robot may be an automatic, self-cleaning litter box, but it still takes a little maintenance to keep it working—and to keep you free from the chore of scooping the litter box! Devoting a few minutes here and there to ongoing maintenance will keep your Litter-Robot in top shape for years to come. If you have any questions, contact Whisker Support.
