Why it matters
The AS11's 16.33 x 15.35 in entrance makes room for cats of most sizes, and PetPivot states a range of 3 to 22 lb. The open top improves airflow and suits cats that refuse hooded boxes.
Safety sensors pause cleaning when a cat is present, PetPivot describes the operation as whisper-quiet, and waste goes into a large bin for multi-day use.
Who it's for, and who should skip it
Good fit if
- Most adult cats
- Cats that avoid hoods
- Quiet rooms
Look elsewhere if
- Homes without a level spot near an outlet
- Cats that are afraid of moving parts
- Kittens under the maker's minimum weight
Pros and cons
Pros
- Stated 3–22 lb range
- Wide entrance
- Quiet
Cons
- Cat count not stated
- Open top can scatter litter
- App features vary by version
Limitations to weigh
- Set it on a hard, level floor near an outlet. Weight sensors read wrong on carpet or uneven tile, which can stop or trigger cycles.
- Automatic cycling has a minimum cat weight; keep automatic mode off for kittens under it and run cleans manually.
- Empty the waste bin before it's full and keep spare bags; an overfull bin is the most common cause of a stalled cycle.
- Running costs come from the bags, liners, filters and litter the maker specifies. The compatibility checker lists refills that state they fit.
