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.
What to Look for in an Automatic Litter Box
Choosing the right automatic litter box involves more than picking a familiar brand. You need reliable sensors to protect your cat, enough waste capacity to reduce emptyings, a quiet motor, and an entry style your cat will actually use. These four criteria shaped our evaluation and should guide your purchase.
Safety Sensors and Motion Detection
An automatic litter box that cycles while your cat is still inside is dangerous and stressful. Look for optical or hall sensors that stop the rake or drum the moment your pet steps in. The Mimfam uses 4 pairs of infrared sensors and 3 hall sensors, giving you a robust safety net that pauses the cleaning sequence and resumes only after your cat leaves.
This extra attention to safety proves essential in multi-cat households where cats often line up to take turns. A unit that protects every cat, no matter their size or curiosity, earns trust over the long run. If you prefer a fully enclosed alternative, our covered litter box guide reviews models that continue to prioritize sensor coverage.
Waste Capacity and Liner Convenience
The whole point of automation is spending less time dealing with waste. A larger bin means fewer interruptions, while disposable liners make disposal clean and quick. The Mimfam comes with a 10L waste container that supports up to ten days of use for a single cat, which is impressive for a top-entry unit at this level.
Multi-cat households will still appreciate the capacity even if they need to empty it more often. The removable bin and included liner bags work together to control odor and simplify your routine. For a more discreet setup, our best hidden litter box guide features furniture-style enclosures that can house automatic boxes without giving up easy access.
Noise Level and Nighttime Comfort
Noise might seem like a minor detail until a rattling litter box wakes the whole house at 2 a.m. A quiet motor keeps cats calm and prevents them from associating the box with scary sounds. The Mimfam runs at roughly 32dB, which is similar to a soft whisper and quiet enough for apartments and open floor plans.
Low noise also means you can run the cleaning cycle at night without disturbing anyone. That flexibility makes daily maintenance feel invisible, and it improves your cat’s confidence with the box. If you plan to place the unit inside cabinetry, our best litter box furniture guide covers ventilation, access, and sizing so you can plan the perfect corner.
Entry Style and Cat Comfort
Cats are picky about how they enter their bathroom. Some want a wide, open view; others crave the security of walls. The Mimfam uses a spacious top entrance that measures 16.33 by 15.35 inches, so even larger breeds can hop in and out without brushing the sides.
An open-top design also helps contain litter and improves airflow, which can reduce odors inside the box. Watching your cat’s behavior is the best way to know whether a top-entry layout suits them. For households that value straightforward cleaning, our stainless steel litter box guide introduces non-porous options that resist stains and smells.
Keeping these four criteria in mind will help you choose an automatic litter box that truly fits your lifestyle. A model that excels in safety, capacity, quietness, and cat comfort will quickly become the hardest-working gadget in your home. Take the time to match the product to your cat’s habits, and you will enjoy a cleaner, more pleasant space.
Final Thoughts
When you balance safety, waste capacity, quiet performance, and cat comfort, the Mimfam Automatic Self Cleaning Litter Box stands out as a dependable pick for 2026. For most households, we recommend the Mimfam Automatic Self Cleaning Litter Box because it combines infrared sensors, a roomy top entry, and a near-silent cycle. For multi-cat homes that need extra capacity, the Mimfam AS11 brings the same proven features with a 10L waste bin that keeps mornings fresh and scoop-free.

Frequently Asked Questions
How often do I need to empty the Mimfam automatic litter box?
With a 10L waste bin, a single cat can go about ten days before an empty. Multi-cat homes should check the bin every three to five days, depending on how many cats share it. The included liners make disposal simple, and the waste bin’s design helps control odor between swaps.
Is the Mimfam self cleaning litter box safe for kittens?
Yes. The unit has 4 pairs of infrared sensors and 3 hall sensors that halt the cleaning motion whenever a cat enters the space. That gives kittens and small adults strong protection during every cycle. In 2026, we still recommend staying nearby for the first few runs so your kitten learns that the motion is harmless.
How quiet is the Mimfam automatic litter box during operation?
It produces about 32dB of noise, making it one of the quieter self cleaning litter boxes we have assessed. You can schedule a cleaning at night without worrying about waking light sleepers. If you prefer a fully private solution, our covered litter box guide lists enclosed models that remain equally unobtrusive.
Does the open-top design reduce litter tracking?
Because cats must jump out of a top entry, loose litter tends to fall off before they step onto the floor. Pairing the Mimfam with the included cat litter mat catches even more granules. While no automatic box can promise zero tracking, this layout keeps your floors noticeably tidier than a front-entry unit.
