Petlibro Air
The Petlibro Air is a self-cleaning cat litter box using a drum rotation mechanism for automatic waste sifting and a built-in ioniser deodoriser for continuous odour control between cycles. Monitoring individual cat weight and visit frequency via the Petlibro app, the Air is positioned as an affordable alternative to the Litter-Robot 4 at approximately $300–$380 on Amazon — roughly half the price while adding built-in deodorisation the Litter-Robot lacks. Suitable for single and multi-cat households.
Whisker Litter-Robot 4
The Whisker Litter-Robot 4 is the current-generation automatic self-cleaning cat litter box, using a patented rotating globe mechanism to automatically sift clumping litter and seal waste into a drawer after each cat visit — eliminating daily manual scooping. OmniSense multi-cat weight detection identifies individual cats by weight, tracks visit frequency, and alerts owners to health pattern changes via the Whisker app. Operating 40% quieter than its predecessor with a larger globe and improved odour control, the Litter-Robot 4 supports households with up to 5 cats and integrates with Alexa and Google Home. Priced at $699, available at litter-robot.com and Amazon.
