The Scoop Robot Pro is new enough that owner experience is limited to three early buyers, and their reports split. One describes solid, quiet hardware that is easy to clean, a live feed that works, no smell after two weeks and a skittish cat that came round. Another found the odour so bad that their cats stopped using it.
The other complaints are about the connected features: recordings that would not play from the cloud (CATLINK says it fixed a US-wide fault), a refiller that did not refill automatically until it was calibrated, cat recognition that missed, and an advert every time the app opens. These are the features that justify the price over CATLINK's cheaper boxes.
Camera buyers who are prepared to wait for firmware to catch up are the audience. One owner of the cheaper Open-X decided the extra money was hard to justify.
