FAQ

Is the Litter-Robot 3 compatible with all types of cat litter?
No, it works best with clumping clay litter. Alternative litters like crystals or pellets can interfere with the sifting mechanism.

How often do I need to empty the waste drawer?
Typically every 7–10 days for one cat, but more often for multi-cat households. The app (on Connect models) will notify you when it’s full.

How many cats can use the Litter-Robot 3?
It supports up to 3–4 cats, though cleaning frequency and litter levels may need closer monitoring.

Does it eliminate litter box odor completely?
Not completely, but the enclosed waste drawer and carbon filter drastically reduce odor compared to standard litter boxes.

Is it noisy during operation?
It makes a low hum during the cleaning cycle but is relatively quiet. Sensitive pets may need a short adjustment period.

Can I use it without WiFi?
Yes, the base model works without any connectivity. The Connect model adds WiFi features but isn’t required for core functionality.

What happens if my cat is inside when the cycle starts?
The unit has weight sensors to detect your cat and delay the cleaning cycle until your cat exits safely.

What is the return policy?
Litter-Robot offers a 90-day in-home trial. If it doesn’t work out, you can return it for a refund (minus shipping).

How long does the Litter-Robot 3 last?
With proper maintenance, it can last several years. Key parts like the motor and globe are durable and replaceable.

Can kittens use it?
It’s not recommended for cats under 5 lbs, as the sensor may not detect them reliably.

How do I clean the unit?
You can wipe down the exterior with a damp cloth, and disassemble the globe for deeper cleaning as needed (every few months).

Does the Litter-Robot 3 track health metrics like the Litter-Robot 4?
No, the Litter-Robot 3 doesn’t track metrics such as litterbox usage trends or cat weight. That feature is exclusive to the Litter-Robot 4.

What if the power goes out?
The unit won’t operate without power. Once power is restored, it will resume normal operation. No waste is lost in the meantime.

Is the Litter-Robot safe for elderly cats or those with mobility issues?
It may be challenging due to the step-entry. You can purchase a ramp accessory to make it easier for senior cats to access.

Do I need to replace the carbon filter often?
Yes, it’s recommended to replace the carbon filter every month or two to maintain odor control.
