What Is the Litter-Robot 4? A 2025 Deep Dive into Self-Cleaning Tech

The Litter-Robot 4 is Whisker's latest iteration of the iconic self-cleaning litter box, evolving since 1998 with smarter sensors and seamless integration. Unlike basic auto-boxes, it's a rotating globe that separates clean litter from clumps via gravity and a sifting system—no rakes to jam. At 29.5 x 27 x 29.5 inches and 29 lbs empty, it fits most bathrooms or laundry rooms, with a spacious 65L waste drawer holding a week's worth for one cat (less for multiples).

Key 2025 upgrades? Deep Sleep mode for quiet nights, optional OdorTrap packs for 4x odor lock, and Whisker app connectivity for iOS/Android. The app logs visits, weight trends, and alerts for issues—early UTI detection via usage patterns. Compatible with clumping clay litter (Arm & Hammer recommended), it uses 7-10 lbs per fill, auto-refilling via optional Hopper. Quiet at 45dB (like a soft hum), it's vet-approved for multi-cats, supporting up to 25 lbs per use. Forbes Vetted calls it "reliable and repairable," with modular parts for 10+ year lifespan. Priced at $699 (bundles $750+ with accessories), it's premium but backed by 90-day trial and 1-year warranty. For eco-minds, recyclable plastics reduce landfill waste by 80% vs. manual scooping.
