Empty the waste drawer when the full indicator shows

The PetSafe automatic litter box has a sliding waste drawer at the bottom that collects clumped litter. When you see the red full indicator light or notice the drawer is visibly full, it's time to empty it. Most models fill after about two weeks of use for a single cat, though this varies based on how many cats use the box and how often they go.

Emptying the drawer takes about two minutes. You don't need to turn off the box or unplug it—just slide the drawer out, dump the contents into a trash bag, and slide it back in. The box will resume normal operation when ready. If you wait too long and the drawer gets completely full, the box may jam or stop raking, so check the indicator weekly.

Key Takeaways

  • Pull the waste drawer straight out from the bottom of the unit and empty the clumped litter into a trash bag.
  • The red full indicator light tells you when the drawer is ready to empty, usually every one to three weeks depending on cat usage.
  • You can empty the drawer without unplugging the box or stopping its cycle—just slide it out and back in.
  • If the drawer is stuck or the box stops raking, the drawer may be overfull; empty it completely and check for litter jams in the rake mechanism.

Locate and remove the waste drawer

The waste drawer sits at the very bottom of the litter box unit. Look underneath the front edge—you'll see a plastic handle or lip that sticks out slightly. Grip this handle with both hands and pull straight toward you with steady pressure. The drawer slides out on tracks and should come free without resistance.

If the drawer won't budge, stop pulling. Check that no litter is blocking the tracks on either side of the drawer opening. Sometimes dried litter or a clump can jam the mechanism. Gently wiggle the drawer side to side while pulling, or use a damp cloth to wipe the tracks clean, then try again. Never force it—forcing can crack the plastic.

Dispose of the litter and clean the drawer

Tip the contents of the drawer into a heavy-duty trash bag. Most of the litter will be clumped waste that the rake has already separated from clean litter. If you use a litter scoop, you can also scoop out any remaining loose litter before reinserting the drawer.

Wipe the inside of the drawer with a damp cloth or paper towel to remove dust and dried litter residue. This prevents buildup that can slow the drawer's movement over time. Let it air-dry for a few seconds, then slide it back into the unit until you hear or feel it click into place. The box will resume its normal cycle once the drawer is fully seated.

Reset the full indicator if it doesn't clear automatically

On most PetSafe models, the red full indicator light turns off automatically once you reinsert the drawer. If the light stays on after you've emptied and reinserted the drawer, the sensor may need to be reset. Check your model's manual for the reset button location—it's usually a small button on the control panel or inside the drawer opening.

Press and hold the reset button for two to three seconds until the light goes out. If the light comes back on when ready after you've just emptied the drawer, the sensor may be dirty. Use a dry cloth to gently wipe the sensor lens (usually a small dark spot inside the drawer opening) and try the reset again. If the light still won't clear, the sensor may need replacement.

Troubleshoot if the drawer is stuck or overfull

If the drawer won't slide out or the box has stopped raking litter, the drawer is likely overfull or jammed. First, unplug the box from the wall outlet. This stops the rake from moving and prevents injury if you're working inside the unit. Wait 10 seconds, then try pulling the drawer out again with steady, even pressure.

If it still won't move, look inside the box from above and check whether litter is blocking the rake or the drawer tracks. Use a small scoop or spoon to remove any large clumps or debris you can reach. Once you've cleared the jam, plug the box back in and test the drawer again. If the drawer still won't budge after clearing visible blockages, the tracks may be bent and the unit may need service.

Maintain the drawer and tracks for smooth operation

Every time you empty the drawer, take 30 seconds to inspect the tracks on both sides of the drawer opening. Dried litter, dust, or cat hair can accumulate here and slow the drawer's movement. Wipe the tracks with a dry cloth or old toothbrush to remove debris. This straightforward step prevents jams and keeps the drawer sliding smoothly.

Once a month, remove the drawer and wipe down the entire inside surface with a damp cloth, including the bottom and sides. Let it dry completely before reinserting. Check that the drawer's plastic edges aren't cracked or warped—cracks can catch on the tracks and cause sticking. If the drawer is damaged, contact PetSafe for a replacement drawer kit, which is usually inexpensive and takes five minutes to swap in.

Frequently Asked Questions

How often should I empty the waste drawer?

Check the full indicator light weekly. For a single cat, the drawer typically fills every one to three weeks. Multiple cats or cats that use the box frequently may require emptying every five to seven days. Don't wait for the light to turn red—empty it as soon as you notice the drawer is three-quarters full to prevent jams.

Can I empty the drawer while the box is plugged in?

Yes, the box does not need to be unplugged to empty the drawer. You can pull it out and reinsert it while the unit is powered on. However, if the drawer is stuck or you're troubleshooting a jam, unplug the box first to stop the rake from moving.

What if litter is stuck to the sides of the drawer?

Dried litter on the drawer sides is normal. Wipe it off with a damp cloth before reinserting the drawer. If litter is caked on heavily, soak the drawer in warm water for a few minutes to soften it, then scrub gently with a soft brush. Dry it completely before putting it back in the box.

Is the waste drawer waterproof?

The drawer is not waterproof, so avoid soaking it or running it under running water. Use a damp cloth to clean it instead. If you do get water inside the drawer, dry it thoroughly with a towel before reinserting it into the box.

What should I do if the drawer keeps getting stuck after I empty it?

Clean the tracks on both sides of the drawer opening with a dry cloth or soft brush to remove litter dust and debris. Check that the drawer's edges aren't cracked or warped. If tracks are clean and the drawer looks undamaged but still sticks, the tracks may be slightly bent—contact PetSafe support for guidance on whether the unit needs service.
