Our verdict
Pick the 5 Pro if you have several cats and want to know which one is using the box and how often. For a single healthy cat, the extra $200 over the Litter-Robot 4 buys data you may never look at.
What we like
- Cameras show which cat used the box
- Most detailed health log in the range
- All the Litter-Robot 5 improvements
- Cameras plus WasteID give the most detailed health log in the Litter-Robot range
- Handles bigger cats (up to 30 lb) than the Litter-Robot 4
- Larger waste drawer: Whisker estimates about 10 days for one cat
What to know
- Free streaming capped at 5 minutes a day
- Key AI features need the Whisker+ subscription
- Most expensive model
- Live streaming is capped at 5 minutes a day unless you pay for Whisker+
- Newer model (late 2025), so there is less long-term owner data
