Litter Robot A1 Smells Bad How to Fix It
If you own a Litter-Robot A1, you know it’s a game-changer for keeping your cat’s litter box clean. However, no matter how smart the technology, bad smells can still happen.Don’t worry if your Litter-Robot A1 bad; it’s a common problem with easy solutions.In this guide, we’ll walk you through the common causes of odor in your-Robot and how to fix them, so your home stays fresh and your cat stays happy.
Why Does Your Litter-Robot A1 Smell?
Before diving into fixes, it’s important to understand why the smell is occurring. Although the Litter-Robot A1 is intended to contain odors, its performance may be compromised by the following: Waste buildup in the base drawer
Either a polluted globe or sensors Poor quality or old litter
Lack of carbon filter maintenance
Humidity or temperature issues
Improper cleaning schedule
Now, let’s tackle each of these issues and how to address them.
1.Empty the Waste Drawer More Frequently
The most obvious cause of foul odors is a full or nearly full waste drawer. The Litter-Robot A1 has a sensor that notifies you when the drawer is full, but even before that, odors can build up.
Solution:
If you have multiple cats, you should empty the drawer at least once every three to four days.
Use odor-control trash bags or liners to trap smell.
Consider sprinkling baking soda or using litter deodorizer in the drawer for extra freshness.
2. Replace or Refresh the Carbon Filter
A carbon filter that removes odors from the waste drawer is included with the Litter-Robot A1.However, this filter doesn’t last forever.
Solution:
Replace the carbon filter every 1–3 months depending on the number of cats and odor levels.
You can also reactivate the carbon filter temporarily by placing it in direct sunlight for a few hours—this helps restore some odor-absorbing capacity.
If you want a stronger option, consider upgrading to charcoal liners or stronger aftermarket filters compatible with the A1.
3. Clean the Globe Thoroughly___
Even though the Litter-Robot A1 rotates to separate waste from clean litter, some clumps and residue can stick to the globe, especially if your cat has soft stool or urinates heavily.
Solution:
Clean the globe at least once every two weeks.
Use mild soap and warm water; avoid harsh chemicals that could damage sensors or plastic.
Dry the globe completely before reassembling.
Don’t forget to check the seal or gasket area around the waste port—it can accumulate debris and smells if not cleaned.
4. Check the Litter Type and Condition
Not all litter is created equal. Some low-quality litters don’t clump well, allowing waste to spread or stick to the globe. Others simply don’t trap odor effectively.
Solution:
Use a high-quality, clumping litter that’s compatible with the Litter-Robot.
Look for unscented, low-dust litter with odor control.
Completely change out the litter every 2–3 weeks, even if you’re scooping regularly.
Also, keep an eye on moisture levels in the litter. Wet litter smells worse and is less effective at clumping.
5. Clean the Base and Sensors___
The base of the Litter-Robot, where the motor and sensors are located, can accumulate grime over time. This is especially true if there’s any overflow or spillage from the waste drawer.
Solution:
Take the globe and drawer out of the unit and unplug it.
Use a damp cloth with mild detergent to wipe down the base—pay special attention to corners and crevices.
Avoid soaking the base, as water can damage the electronics.
Carefully clean around the sensors with a soft, dry cloth.
This not only helps with odors but also keeps your Litter-Robot running smoothly.
6. Improve Ventilation and Environment
The Litter-Robot itself may not always be the issue, but rather the room it is located. High humidity and poor air circulation can worsen any existing odor.
Solution:
The Litter-Robot should be placed in an area with adequate ventilation.
Use a small air purifier or a fan to keep air moving.
Avoid placing the unit near vents or heating systems that can make odors stronger.
If you live in a humid climate, consider using silica gel packs or dehumidifiers near the litter box area.
7. Consider Litter-Robot Deodorizers or Accessories
Litter-Robot provides a number of accessories that can aid in odor control: OdorTrap™ Packs: These are designed to neutralize smell in the waste drawer.
Drawer liners: Make cleaning easier and more hygienic.
Litter-Robot cleaning wipes: For quick spot cleaning.
While these aren’t required, they can be helpful if you’re still noticing smells even after cleaning.
8. Establish a Regular Cleaning Routine
Even with automation, your Litter-Robot needs regular attention. Setting a schedule can help prevent bad smells from building up.
Recommended Routine:
Daily: Check waste drawer and litter condition
Every 3–4 days: Empty drawer and top off litter
Weekly: Wipe down globe, check filter
Bi-weekly: Deep clean globe and wipe base
Monthly: Replace carbon filter, refresh all litter
Use reminders on your phone or smart home assistant to stay on top of it.
