Key Takeaways: Litter Robot 3 vs 4
- Noise Levels: The Litter-Robot 4 offers significantly quieter operation with WhisperQuiet™ technology, making it ideal for sensitive cats and owners.
- Sensor and App Improvements: The Litter-Robot 4 includes advanced sensors and improved app integration, allowing for better monitoring and customization.
- Odor Control: Both models have effective odor control, but the Litter-Robot 4 enhances this with a more efficient sealed waste drawer and better filtration.
Comparison of Litter-Robot 3 and Litter-Robot 4
1. Noise Level and Operation
The Litter-Robot 3 can be noisy during its cleaning cycle, often reaching up to 65 dBA, which may be heard from other rooms. This can be distracting for both cats and owners. The Litter-Robot 4, however, features WhisperQuiet™ technology that reduces the noise significantly, making it nearly silent and less disruptive during operation. This is especially beneficial for owners who keep their litter box in common areas or near sleeping spaces.
2. Sensor Technology
The Litter-Robot 4 has improved sensor technology, incorporating both weight and laser sensors for more precise monitoring. It uses OmniSense™ detection to track cat usage and detect when the waste drawer is full, ensuring real-time updates through the Whisker app. In contrast, the Litter-Robot 3 relies solely on weight sensors, which can sometimes be less accurate, especially if lighter litter is used. The updated sensors in the Litter-Robot 4 provide more reliable performance and safety by halting the cleaning cycle if a cat enters during operation.
3. Odor Control Features
While both models offer odor management, the Litter-Robot 4 takes it a step further. It has a sealed waste drawer designed to prevent odors from escaping, and it uses an upgraded filter system that is more effective at neutralizing smells. The Litter-Robot 3 also has a functional odor control system, but the design of its waste drawer allows for some odors to escape if not emptied frequently. For households sensitive to smells, the Litter-Robot 4 provides a superior solution.

Major Differences Between Litter-Robot 3 and Litter-Robot 4
- Noise Reduction: The Litter-Robot 4 is equipped with WhisperQuiet™ technology, making it significantly quieter compared to the Litter-Robot 3, which has a more audible cleaning cycle.
- Sensor and App Capabilities: The Litter-Robot 4 offers advanced monitoring with OmniSense™ technology and weight tracking, while the Litter-Robot 3 uses basic weight sensors for cycle activation.
- Odor Management: The Litter-Robot 4’s upgraded, sealed waste drawer and improved filtration provide better odor control than the Litter-Robot 3, making it more suitable for smaller spaces.
Frequently Asked Questions (FAQ): Litter Robot 3 vs Litter Robot 4
Q: What happens if my cat goes back into the Litter-Robot during the delay cycle?
A: Both the Litter-Robot 3 and 4 are designed with safety sensors to detect if a cat re-enters during a cleaning cycle or delay period. If this happens, the cleaning cycle will pause, and the device will resume only after the cat has safely exited.
Q: My Litter-Robot smells, and it makes my house smell bad. What can I do?
A: If odors are an issue, try using low-dust, clumping litter recommended for Litter-Robot models. Additionally, make sure to empty the waste drawer frequently and replace the filters as needed. For the Litter-Robot 4, using the OdorTrap™ feature will also help neutralize smells more effectively TechnoMEOW.

Cleaning and Maintenance Guide
Proper maintenance is essential for ensuring both the Litter-Robot 3 and 4 operate efficiently. Each model has specific maintenance steps to keep it functioning well and prolong its lifespan:
- Litter-Robot 3: This model requires routine emptying of the waste drawer, typically once a week for single-cat households. A full deep clean of the globe and base is recommended every 1-2 months. Users should remove the bonnet and globe, cleaning them with mild soap and water. The weight sensors should also be inspected regularly to ensure they’re not obstructed by litter buildup. It’s also crucial to check the waste drawer sensors for dust and debris to prevent false “full” alerts.
- Litter-Robot 4: The newer model simplifies maintenance with a sealed waste drawer and an improved filtration system, making odor control more effective. The waste drawer must be emptied as indicated by the app, usually once a week. For deep cleaning, the globe and base should be disassembled and washed every few months, and the laser sensors should be wiped down with a soft cloth to prevent dust interference. The design enhancements in the Litter-Robot 4 reduce litter tracking, which keeps the base and surrounding area cleaner.
Safety Features and Enhancements
The Litter-Robot 4 includes multiple safety enhancements compared to its predecessor:
- Advanced Sensors: The Litter-Robot 4 features OmniSense™ detection, which includes both laser and weight sensors to monitor the entry and exit of cats more precisely. This dual sensor system prevents the cleaning cycle from starting if a cat is detected inside or near the entryway. It’s a significant improvement over the Litter-Robot 3, which uses only weight sensors that can sometimes be less reliable.
- Cycle Delay Customization: This feature allows owners to set a delay time (ranging from 3 to 30 minutes) before the cleaning cycle begins. This customization helps ensure that if a cat re-enters the box during the delay, the cycle will not activate prematurely, reducing the risk of accidents. The Litter-Robot 3 does not offer this level of customization, making the newer model more adaptable to multi-cat households.
- Nightlight: Both models have nightlights, but the Litter-Robot 4’s is positioned at the entryway, illuminating the litter bed directly. This feature is particularly helpful for older cats or those with vision issues, as it enhances visibility during nighttime use. The Litter-Robot 3 has a nightlight located under the bonnet, which may not be as effective in illuminating the litter area.
FAQ Section
Q: What happens if my cat goes back into the Litter-Robot during the delay cycle?
A: Both the Litter-Robot 3 and 4 have sensors that detect if a cat re-enters during a delay cycle or cleaning process. If this occurs, the system will pause the cleaning cycle immediately to ensure your cat’s safety. The cycle will resume only after the cat has exited the litter box.
Q: Why does my Litter-Robot smell, and how can I prevent it?
A: If your Litter-Robot is emitting an odor, it may be due to an overdue waste drawer emptying or a need for a deep clean. Ensure that the waste drawer is emptied as indicated by the app, and replace filters regularly. Using low-dust, clumping litter also helps reduce odors. For the Litter-Robot 4, the sealed waste drawer and advanced filtration system should minimize smells when maintained properly.
Q: Is the Litter-Robot 4 better for multiple cats compared to the Litter-Robot 3?
A: Yes, the Litter-Robot 4 is specifically designed to handle up to four cats efficiently. Its advanced sensors and the OmniSense™ system provide real-time monitoring of multiple cat entries, making it more suitable for multi-cat households. The Litter-Robot 3 can manage multiple cats but may not provide the same level of tracking and monitoring as the newer model.
