How the Litter-Robot 4 Works
Understanding the mechanics helps you troubleshoot and optimize performance. The Litter-Robot 4 follows a simple, repeatable cycle each time a cat exits the globe.
The Automated Cleaning Cycle
- Detection – Infrared sensors detect when a cat walks out, confirming an elimination event.
- Delay – A 5‑second pause allows the litter to settle and any clumps to form.
- Rotation – The globe rotates 360°; waste slides through a fine mesh into the drawer while clean litter returns to the base.
- Seal – The waste drawer automatically locks, sealing odors until you empty it.
Smart Features Explained
- Weight‑Based Reset – If the waste drawer reaches 85 % capacity, the system sends a push notification.
- Sleep Mode – During low‑activity periods (e.g., nighttime), the robot enters a low‑power state, extending bulb life and reducing noise.
- Health Dashboard – The app logs each cycle, enabling owners to spot changes in litter usage that may indicate health issues.
