Stop scooping. Four cats, one Litter-Robot.
I have run a Litter-Robot in this house since the 3 Connect. The 5 Pro is the first one that knows which cat used it, flags changes in bathroom habits, and stays quiet enough that Luna stopped side-eyeing it. Every model comes with a 90-day in-home trial, so if your cat refuses it, you send it back.
Which Litter-Robot should you buy?
Short version: buy the Litter-Robot 5 Pro if you have more than one cat or you care about health tracking. Buy the Litter-Robot 4 if you want the proven model at a lower price. Buy the EVO if you have one cat and a small space. Skip used Litter-Robot 3 units at this point, the parts are getting hard to find.
| Model | Best for | Cats | Standout feature | Price |
|---|---|---|---|---|
| Litter-Robot 5 Pro | Multi-cat homes, health tracking | Up to 5 | Dual AI cameras, cat ID, health alerts | $899 |
| Litter-Robot 5 | Multi-cat homes on a budget | Up to 5 | WasteID odor targeting, quieter cycle | $799 |
| Litter-Robot 4 | Most households | Up to 4 | OmniSense detection, OdorTrap | $699 |
| Litter-Robot EVO | One or two cats, small spaces | 1 to 2 | Compact footprint, simple app | $599 |
Every model ships with a 90-day in-home trial. If your cat refuses it, you send it back. Mine took between two days (Luna) and two weeks (Minnie Mouse) to fully switch over.
