Why it is listed
Litter-Robot EVO is the compact Whisker globe: two cats, 19 lb ceiling, smaller footprint, step in the box. It scores close to LR4 because ease is better and the mechanism is the same family — not because it is a 4-cat machine.

Pros & cons
Pros
- Official EVO page: 20.6×24.3 in footprint, 27.6 in tall, 21.5 lb empty, 14.85 in entry, step included, up to 2 cats, 3–19 lb, ~7 days between empties for one cat.
- Same sealed carbon-filtered drawer, QuietSift, Whisker app, 90-day trial. Comparison chart: carpet tray built in; waste sensing is full-only (not any-level).
- Lowest Whisker list price on this table without dropping to a rake tray.
Cons
- Hard cap: 2 cats and 19 lb. A Maine Coon household is the wrong SKU — Whisker says use 4 or 5.
- No WasteID, no any-level waste sensing, smaller drawer than LR4/5.
- Still ~$600. Compact is relative; it is not a hidden-under-the-sink box.
