Mimfam Automatic Self-Cleaning Litter Box AS11 review

A named grey offer with a short list of confirmed trade-offs

The Mimfam AS11 is a grey automatic litter-box listing with a distinct product identity: Mimfam gives it the AS11 code and UPC 199284528147. Its product page calls the design open-top and describes sensor-controlled cleaning, a removable 10-liter waste drawer and disposable liners. That is enough to understand the broad proposition, but not enough to assume the familiar details of another AS11-branded listing. A separate PetPivot product also uses AS11; I found no manufacturer crosswalk or shared manual that establishes whether the physical machines are the same or different. This review keeps the Mimfam offer under its own brand and UPC and does not borrow PetPivot’s operating instructions.

For a buyer who wants an open view rather than a covered tunnel, the entrance shape is the most visible choice. Mimfam describes a top opening and gives 16.33 by 15.35 inches as its entry measurement. The page does not give overall width and depth, nor make the measurement axes clear enough to use as floor footprint. Measure the actual spot from a separate reliable drawing or inspect a unit before committing to a tight alcove; do not treat the opening dimensions as the space the box occupies.

What the sensor claims do—and do not—tell you

Mimfam lists four pairs of infrared sensors and three Hall sensors. The product description says cleaning pauses when the sensors detect a cat and resumes after the cat exits. That describes the intended automatic routine, not an independently tested safety system. The materials I reviewed do not identify the separator or cleaning motion, the post-exit wait, the length of a full cycle, or minimum cat weight and age. If any one of those limits is essential—for example, automatic operation for a small kitten—this listing does not supply the answer. A sensor count is not a substitute for an operating manual or a cat-size boundary.

The listing-linked promotional image labels the AS11 “No App.” That makes the product relevant to someone who prefers a phone-free setup, but it also rules it out when remote alerts, visit history or app reporting are non-negotiable. No Wi-Fi band, camera, individual-cat tracking, screen or local counter is established in the Mimfam materials. Avoid reading those features into the AS11 code or into the product’s sensor language.

Ten liters is a capacity claim, not a multi-cat schedule

The page describes a removable 10-liter waste container and says liner bags and a litter mat come with the listed offer. It separately claims that one cat may go up to ten days without manual scooping. Treat that as a manufacturer interval claim for the single-cat context only; it is not an observed result, and it does not establish how often a multi-cat household should empty the drawer. The same page uses multi-cat marketing wording but gives no numerical household-capacity rating. If the questionnaire needs a specific maker-rated cat count, this AS11 remains a poor match rather than earning credit from “multi-cat” phrasing.

The bin volume is useful for a narrower comparison: the product page claims 10 liters, but the interval between emptying still depends on the home and the claim does not replace routine checks. The listing says its waste drawer is removable and uses disposable liners; exact liner quantities are not clear from the details I reviewed. A larger nominal container can reduce the number of trips to the bin, but it cannot promise a particular odor result or unattended period.

The litter system is the biggest unanswered buying question

The available Mimfam product details do not name a litter type, particle size or cleaning mechanism. It is therefore not responsible to call the AS11 a clumping-litter sifter, a crystal rake or a globe, even though those are common designs in this category. If your cat requires a specific substrate, keep that requirement hard and choose a model whose own page or manual confirms it. If the litter type must remain unchanged and the Mimfam compatibility is unknown, do not treat a product photograph or the shared AS11 code as proof.

This is also why the AS11’s “up to ten days” statement should not be used to infer what litter it separates. That statement describes the claimed drawer routine, not a compatibility table. Without a Mimfam manual, the article cannot confirm litter depth, fill line, cleaning mode, setup steps, cleaning intervals or replacement parts. Those are real ownership costs, not details to fill in from a neighboring product.

Who should shortlist it—and when to choose another documented plan

Keep the Mimfam AS11 in view if open-top access, app-free operation and a stated 10-liter waste drawer are the features you want to compare, and if the type of litter, exact motion and numeric cat limits are not essential filters. The page’s listed sensors and single-cat interval may help frame questions for the seller, but they are not independent performance evidence. Pass if you need a written litter specification, a known cat-count or weight limit, a complete cycle time, measured noise or a precise room footprint before buying.

For a better documented comparison, see the PetPivot AutoScooper 11. Its separately published manual covers a clumping-litter sifter plan and gives cat age and weight restrictions; those facts apply to that PetPivot offer, not automatically to Mimfam. Both pages use AS11, but a code overlap is not a parts crosswalk. Choose between the listings only on facts attached to the exact brand and offer you plan to purchase. There is no hands-on test or customer-review summary behind this assessment.
