In this review, I’ll share the details on the Litter-Robot 4, including my experience and analysis of whether or not the newest automatic litter box from Litter-Robot is worth the almost-$650 price tag. I took notes on how my cats responded to the design, how well the new sensor system worked, and how effectively it sifted. To understand how the new Litter-Robot 4 works and whether or not it’s worth it, I spent a month testing the unit with my two cats, Wessie and Forest. With a larger entryway, additional sensors that make it accessible to cats of all ages and sizes, and an improved app interface that gives you real-time updates on your litter and waste drawer level, the most significant changes to the Robot’s design revolve around cat-friendliness and ease of use.Ĭonsidering that these changes solve some of the most common complaints about the older model, this release demonstrates Whisker’s commitment to innovation and meeting users’ needs. After a month of in-home testing, the Litter-Robot 4 has proven its worth as a high-performing, more cat-friendly improvement on the previous Litter-Robot 3.
