Overview
This teweoa AS11 is a self-cleaning litter box with an open top rather than an enclosed dome, aimed at multi-cat homes. It is rated for cats up to 22 pounds and includes multiple built-in safety sensors meant to stop the rake cycle if a cat is inside.
The open-top layout trades odor containment for easier entry and exit, which can matter for older or larger cats that dislike hooded boxes. At 21.6 pounds and roughly 22 by 20 by 24 inches, it is a substantial unit that needs real floor space, not a compact tucked-away footprint. The listing does not name an app or connectivity feature, so automation appears limited to the cleaning cycle itself.
- Automatic self-cleaning rake cycle
- Open-top design for cat comfort
- 22 lb maximum weight capacity
- Low noise operation with safety sensors
Who it's for
Fits households with more than one cat that want automated waste removal without a fully enclosed hood. Cat owners in small apartments or those wanting app-based monitoring should measure the footprint and check for smart features elsewhere first.
Strengths and trade-offs
Drawn from this product's published specifications.
- Rated for cats up to 22 pounds
- Multiple built-in safety protection devices
- Open top eases entry for cats wary of enclosures
- No lid means less odor and litter containment
- Large footprint at roughly 21.5 x 20 x 24 inches
- Only a 1 year warranty
Performance notes
Safety protection is described as multiple devices rather than a single sensor, which matters for a self-cleaning mechanism where a cat could be caught mid-cycle. Low noise operation is listed as a feature, relevant since rake-style boxes are often the loudest part of automatic litter systems.
