❓ Frequently Asked Questions About the Litter-Robot 4
🧽 How does the Litter-Robot 4 self-cleaning system work?
The Litter-Robot 4 automatic litter box uses a patented rotating sifting mechanism that separates clumped waste from clean litter minutes after your cat leaves. Waste is deposited into a sealed, odor-controlled drawer — eliminating the need for daily scooping.
🔌 Does the Litter-Robot 4 need to be plugged in all the time?
Yes. For the self-cleaning cycle, odor control fans, and sensor-based monitoring to function, the unit must remain connected to a standard power outlet. It also ensures seamless communication with the Whisker app for real-time tracking.
📱 Can I track my cat’s bathroom habits with the Whisker app?
Absolutely. The Litter-Robot 4 app integration lets you monitor usage frequency, waste drawer status, and litter levels, and even receive maintenance reminders — all from your smartphone, anywhere in the world.
🧴 What type of litter works best with the Litter-Robot 4?
For optimal clump separation and sensor accuracy, use a high-quality, low-dust clumping clay litter. Avoid non-clumping, pellet, or crystal litters, as they may affect performance and cleaning efficiency.
🧼 How often should I empty and clean the waste drawer?
For a single cat, empty the drawer once per week; for multi-cat households, every 3–4 days is ideal. The app will send alerts when it’s full, making maintenance effortless.
🛠️ Is the Litter-Robot 4 easy to maintain?
Yes. The globe and waste drawer are quick to disassemble for deep cleaning. Simply wash with mild soap, replace the waste liners weekly, and refresh the carbon filters or OdorTrap™ packs every month to keep the unit fresh and running like new.
