Whisker Litter-Robot 5 vs Whisker Litter-Robot 5 Pro
Both makers say their sensor detects cats from 3 lb, so the kitten threshold does not separate them. The Whisker Litter-Robot 5 lists for about $100 less on its maker's store. Every other published figure for both is in the table, with the rows where they differ tinted.
Whisker
Whisker Litter-Robot 5
~$799
Whisker's 2025 replacement for the LR4 keeps the same 22-by-27-inch footprint and entry but raises the rated weight to 30 lb and the cat count to five.
Best for: Large multi-cat homes that want visit-level tracking without a camera
The maker publishes no drawer volume, so the days cannot be worked out. Its own claim is up to 10 days for one cat.
Whisker
Whisker Litter-Robot 5 Pro
~$899
What the extra $100 over the LR5 buys is a pair of AI cameras: one identifies which cat walked in by face, the other looks down at the litter bed.
Best for: Multi-cat homes where telling similar-weight cats apart matters
The maker publishes no drawer volume, so the days cannot be worked out. Its own claim is up to 10 days for one cat.
