About
What it is.
Litter-Robot 4 is Whisker's automatic litter box, built around a globe-shaped chamber mounted on a base rather than the tray-and-motor layout of older self-cleaning boxes. After each cat visit, a motion sensor triggers a sifting cycle that separates clumps and drops them into a sealed, carbon-filtered waste drawer, keeping the litter bed (about 14 inches across) clean between uses.
The wider front entryway and covered, hooded design suit multi-cat households and larger breeds, while an optional fence snaps onto the base rim for extra containment. Whisker's companion app connects over Wi-Fi, letting owners check waste drawer levels and usage patterns remotely. At roughly 24 pounds empty and about 29.5 x 27 x 22 inches, it's sized for a dedicated spot in the home rather than tight bathroom corners.
The verdict
The Litter-Robot 4 excels at odor control and cuts litter-box maintenance time, earning strong buyer satisfaction (4.5/5 from over 16,000 reviews), though its $699–$799 price and large footprint deter cost-conscious or space-limited households.
