Rail-Moving Cat Litter Box

The following cat litter boxes may involve rail-moving or similar rotating/sand-scooping structural designs, meeting the requirements for 'rail-moving':

1. Air Radish Automatic Cat Litter Box C20 This model explicitly adopts a rotating automatic feces-scooping structure, separating feces from cat litter through internal rotating components. It comes with a large 6L waste collection box, supporting up to 3 days without cleaning. Another description of this model mentions 'dual-rail scraping + airflow guidance technology', achieving a 98% sand recovery rate through dual-rail design and reducing cat litter waste. This dual-rail structure may involve a rail-moving mechanism, guiding the scraper's movement along the rails to enhance cleaning efficiency.

2. Petkit Smart Automatic Cat Litter Box MAX2 This model utilizes a spiral drum filtration technology, separating feces from cat litter through drum rotation. Its wall adhesion rate is 40% lower than that of traditional drums. Although it does not directly mention 'rails', the spiral structure essentially achieves material separation through rotation, similar in logic to rail-moving, both completing cleaning tasks through mechanical motion. Its design may reduce cat litter residue by optimizing the drum's shape or surface material.

3. Homann Smart Automatic Cat Litter Box Extra Large This model mentions a 'flat-scooping cleaning technology' but does not explicitly specify rail design. Flat-scooping typically refers to cleaning feces with a horizontally moving scoop. If the scoop's movement path is a fixed rail, it can be classified as a rail-moving structure. Further review of the product manual or contact with the manufacturer is needed to confirm technical details and determine if it meets the requirements.

Notes:

• Definition of 'rail-moving': In automatic cat litter boxes, rail-moving typically refers to structures where internal components (such as rotating drums, scrapers, or scoops) move along fixed paths. This requires judgment based on the specific model's functions. For example, the dual-rail scraping technology of the Air Radish C20 explicitly involves rail design, while the spiral drum of the Petkit MAX2 achieves similar functions through rotation.
• Safety and cleaning convenience: When selecting, prioritize safety features such as anti-pinch sensors and emergency braking, as well as maintenance convenience like waste collection box removal and filter cleaning. It is recommended to choose brands with third-party safety certifications (such as CE, FCC) to reduce usage risks.

For a more precise description of 'rail-moving', it is recommended to directly review the product manual or contact the manufacturer to confirm technical details and avoid selection errors due to functional misunderstandings.
