Ranked #3 in Best Litter Boxes

PETKIT Purobot Ultra

4.2

4 sources2 derived$799.99as of Aug 2

WIRED reviewer rated the Petkit Purobot Ultra 8/10, praising its AI facial recognition and video monitoring capabilities. The device uses a rotating camera to record cats using the box and tracks usage via app. However, the video quality is described as poor and the AI's accuracy decreases after the 30-day free trial. The reviewer noted that while the box is effective for monitoring cat health through stool analysis, the video feed is difficult to observe due to low resolution. It's best suited for cat owners who want smart monitoring features but may not be ideal for those seeking high-quality video footage.

Strengths

— AI-powered facial recognition for multiple cats
— Camera records inside the litter box with night vision
— Self-emptying litter box with airtight waste bag

Watch-outs

— Video quality is low-resolution and black-and-white
— AI recognition accuracy drops after premium trial ends

How they stack up

Arm & Hammer Sifting Litter Box

The Arm & Hammer Sifting Litter Box's no-scoop feature and sifting technology differ from the Petkit Purobot Max Pro 2, which requires manual cleaning but offers smart monitoring. Compared to the Petlibro Luma, it lacks health tracking but provides a more traditional sifting solution for pine pellet litter users.

PETKIT Purobot Ultra

The Petkit Purobot Ultra's low-resolution video and declining AI accuracy after the trial period make it less appealing than the Max Pro 2, which offers better long-term facial recognition and health tracking. Compared to the Petlibro Luma, it lacks detailed health insights but provides a rotating camera for monitoring, which the Luma does not feature.
