Direct answer
Choose the AS11 when price sensitivity, app-free operation and a straightforward open top matter most. Choose Neakasa M1 Plus when you want an open top with a larger stated waste capacity, app monitoring, broader published cat-fit guidance and a more developed support presence.
| Design | Both are open-top rolling/sifting machines. |

| Cat guidance | AS11 materials commonly state 3–22 lb; Neakasa states 2.2–33 lb. |
| Entry | Both have elevated entries; Neakasa publishes 13.86 in. |
| Waste capacity | AS11 public materials conflict between 7 L and 10 L; Neakasa publishes 11.23 L. |
| Support confidence | AS11 is seller-dependent; Neakasa has official product and support pages. |
| Best fit | AS11 for simplicity/value; Neakasa for premium open-top features. |
Cat acceptance
Both avoid a fully enclosed globe, which may help enclosure-averse cats. Neither should be treated as low-entry. Mobility-limited cats may need a stable step or a different design.
Safety documentation
Both describe infrared and weight-related sensing, but Neakasa publishes a clearer current support path. AS11 buyers must verify the exact seller, hardware and manual.
Litter
AS11 manuals favor bentonite/mineral clumping litter. Neakasa specifies fast-clumping scoopable litter within published particle dimensions.
