Litter-Robot 3 had a long useful run, but it is no longer a normal new-product recommendation in the US. Whisker explicitly says LR3 and LR3 Connect were discontinued. A current review therefore needs to help existing owners and cautious legacy buyers—not send readers to a generic Amazon search full of mixed units and parts.
Quick verdict
Keep a working LR3 if it meets your needs and maintain it through Whisker’s support catalog. Consider a Whisker-reconditioned unit only when its price, stated one-year warranty, and 90-day trial beat the case for a newer model. Avoid poorly documented used units whose sensors, motor, bonnet, globe, or drawer-full system cannot be tested.
Amazon still exposes an exact gray Litter-Robot 3 Connect listing, but Whisker has discontinued the model. Treat that action as a listing check, not a blanket recommendation: verify seller, condition, warranty, and return terms before comparing it with Whisker’s current models.
Current status and specifications
| Item | Whisker’s information |
|---|---|
| US status | Discontinued |
| Footprint | 24.25 x 27 inches |
| Height | 29.5 inches |
| Entry | 10.25 x 15.25 inches |
| Empty weight | 24 pounds |
| App | Included on LR3 Connect; not on the original non-Connect base |
The smaller entry and wider footprint are meaningful when comparing LR3 with newer models. Measure the cat and the working floor area, including drawer and cleaning clearance.
Used and reconditioned checklist
Ask for a full clean cycle on video, verify the serial/model type, test cat detection and drawer-full indication, inspect the globe liner and waste seals, and confirm that the bonnet stays latched. Check for error lights, unusual motor noise, corrosion, odor, and damaged wiring.
A private used sale usually lacks the protections of Whisker’s reconditioned offer. Price in missing warranty, deep cleaning, replacement parts, and the risk that a fault appears only after several cycles.
Support is still a strength
Whisker continues to publish LR3 troubleshooting and sell many replacement components. That repair path can make an existing unit worth keeping. It does not make every second-hand unit a bargain; parts plus time can quickly erase the discount.
LR3 versus current models
Whisker directs US shoppers toward Litter-Robot EVO, Litter-Robot 4, and the Litter-Robot 5 family. Newer models offer current sales support and revised features, while LR3 can win only on a substantial, protected price advantage or an owner’s familiarity with its repairable design.
Bottom line
Litter-Robot 3 is now a legacy ownership decision. Existing owners have a real support path. New buyers should demand working proof and meaningful savings, preferably through Whisker’s reconditioned channel when stock exists. Otherwise, move to a current model.
