- How is the Litter-Robot 4 different from the Litter-Robot 3?
- The 4 has a quieter motor, a wider opening, per-cat weight tracking and a redesigned app. It also adds more sensors for litter level and drawer status.
- How many cats can it handle?
- Whisker rates it for up to four cats in a household. With more cats, the waste drawer fills faster and needs more frequent emptying.
- What litter does it use?
- It works with standard clumping clay litter. Crystal, pellet and non-clumping litters are not recommended because the sifting relies on clumps.
- Do I need the app to use it?
- No. The box cycles and sifts on its own, and the app adds weight tracking, litter level and drawer alerts.
- What is in the Core Bundle?
- The bundle centers on the Litter-Robot 4 unit with its waste drawer liners and carbon filters. Check the box contents for the exact accessories included.
- How much space does it need?
- Allow room for the unit plus clearance around it so the globe can rotate freely. It is noticeably larger than a standard open litter box.
- Where is the Litter-Robot 4 Core Bundle by Whisker cheapest?
- At Lowe's, for $799.00, as of our latest check.
