Automatic litter boxes promise to free you from this routine, but with so many options on Amazon, choosing the right one can feel overwhelming. In this guide, we compare two of the best automatic litter boxes on Amazon for 2026: the Ellenpent Automatic Litter Box, Self Cleaning Litter Box and the Furrykiddy Automatic Self Cleaning Litter Box. Whether you have a single cat or a multi-cat household, we will help you find the model that best fits your needs.

- Large waste capacity means less frequent emptying, perfect for multi-cat households
- Quiet operation won't scare cats or disrupt your home
- Easy setup and maintenance according to user reviews
- Spacious top entry accommodates cats up to 22 lbs

The Mimfam Automatic Self Cleaning Litter Box (model AS11) is designed for cat owners who value convenience and safety. It suits multi-cat households and those with larger breeds, thanks to its spacious top entry and generous 10L waste container. This self-cleaning box automates scooping, freeing up your time while keeping the litter area fresh.
Standout features include four pairs of infrared sensors and three hall sensors that halt the cleaning cycle if your cat re-enters, ensuring no accidents. The 10L waste bin holds up to 10 days of waste for a single cat, reducing daily chores. User reviews praise its quiet 32dB operation, which keeps cats calm and homes peaceful.
The open-top design is well-received for reducing litter tracking and providing easy access. The polypropylene build is durable and easy to clean, though some users note the sensors can accumulate dust over time, requiring occasional wiping. The included litter mat and liner bags add value, making setup straightforward.
Drawbacks include the front button placement, which cats may accidentally press, and the cost of replacement waste baskets. A few users mention that the sensor dust film can cause false stops, but regular maintenance solves this. Despite these issues, the overall feedback is highly positive, with many calling it a lifesaver.
Verdict: The Mimfam AS11 is a reliable, safety-focused automatic litter box that excels in multi-cat homes. Its large capacity, quiet operation, and robust sensor system outweigh minor design quirks. If you want to stop scooping daily and prioritize your cat's comfort, this is a solid investment.
Buying Guide: What to Look for in an Automatic Litter Box
Before you decide which model is right for your home, consider these key factors. Every automatic litter box on the market balances convenience, safety, and odor management differently. Understanding these criteria will help you make an informed choice.
Safety Features and Sensors
The most important aspect of any self-cleaning litter box is how it protects your cat. Look for models with infrared or weight sensors that pause the cleaning cycle the moment your cat approaches or enters the unit. Both the Ellenpent and Furrykiddy models include such sensors, but the Furrykiddy goes a step further with a dedicated Kitten Mode that deactivates automatic cleaning entirely. This is especially valuable if you have young or curious cats. You can also read our review of the IRIS USA Top Entry litter box for another perspective on safety design.
Odor Control and Waste Capacity
No one wants a litter box that stinks up the room. The best automatic litter boxes use sealed waste bins and layered odor defenses. The Ellenpent model features an integrated ABS material that prevents urine leaks and an odor-proof cover plus scented gel for a consistently fresh scent. Its 9-liter bin can last up to 10 days. The Furrykiddy model uses a 12-liter tightly closed bin that can go 10 to 15 days between changes. Larger bins mean less frequent emptying, which is a major convenience. For more on odor control, check out our guide to the best litter boxes for odor control.
App Connectivity and Health Tracking
Smart features are becoming standard in modern automatic litter boxes. Both the Ellenpent and Furrykiddy models offer 2.4GHz Wi-Fi connectivity and dedicated apps. You can monitor your cat’s bathroom frequency, weight trends, and receive alerts when the waste bin is full. The Ellenpent app even lets you initiate a deep clean cycle remotely. If you value data-driven pet care, an app-connected litter box can give you peace of mind. For apartment dwellers who need a discreet solution, see our top picks for apartment-friendly litter boxes.
Noise Level and Compatibility
Quiet operation is crucial if you place the litter box in a bedroom or home office. The Furrykiddy model advertises operation under 35dB thanks to a silicone silent roller system. The Ellenpent model does not specify decibels but uses a standard rotation mechanism. Also consider litter compatibility: both models work with clumping, crystal, and tofu litters, but the Furrykiddy is better suited for larger cats (up to 18 lbs) and multi-cat households thanks to its 65-liter globe.

Final Thoughts
After comparing these two automatic litter boxes, the choice comes down to your priorities. The Ellenpent Automatic Litter Box, Self Cleaning Litter Box shines with its dual-layer odor control system, smart app control with health tracking, and a setup that requires no tools, making it ideal for cat owners who want a worry-free experience without any assembly. On the other hand, the Furrykiddy Automatic Self Cleaning Litter Box stands out with its quiet operation, larger waste bin, and dedicated Kitten Mode for safety, making it a versatile choice for households with young cats or multiple felines. Both models offer robust self-cleaning performance, but if you prioritize odor control and app insights, go with Ellenpent; if quietness and extra safety features matter more, choose Furrykiddy. Whatever you pick, you will soon wonder how you ever lived without an automatic litter box.

Frequently Asked Questions
How often do I need to empty the waste bin?
The frequency depends on the model and how many cats you have. The Ellenpent litter box has a 9-liter bin that lasts up to 10 days for a single cat, while the Furrykiddy model’s 12-liter bin can go 10 to 15 days. For multi-cat households, you may need to empty it every week. Both models send alerts through their apps when the bin is full.
Is it safe to use with kittens?
Yes, but with caution. The Furrykiddy model features a dedicated Kitten Mode that fully disables automatic cleaning, which is recommended for cats under 2.2 pounds. The Ellenpent model also has safety sensors that pause cleaning if a cat enters, but it lacks a separate kitten setting. Always supervise young cats initially and consult the manual for weight requirements.
Can these litter boxes use any type of litter?
Both the Ellenpent and Furrykiddy models are compatible with clumping, crystal, and tofu litters. Avoid non-clumping or very fine litters, as they may not work well with the self-cleaning mechanism. The Furrykiddy model is particularly noted for saving litter due to its large globe design. For more tips on litter selection, see our guide to high-sided litter boxes.
How quiet are these automatic litter boxes?
The Furrykiddy model operates at under 35dB, which is quieter than a typical conversation, making it suitable for bedrooms. The Ellenpent model does not specify a decibel rating, but user reports indicate it is reasonably quiet. If noise is a major concern, the Furrykiddy is the better choice.
