Year 1, documented cost of ownership
What each robot actually costs to own
Purchase price plus documented consumables, subscription gating, and replacement events. Bars share one dollar scale, so length is directly comparable. Costs are typical, drawn from manufacturer maintenance guides and owner reports.

Cloud storage subscription pricing hidden from product page
Price undisclosed on product page

Annual cost by part type
Read from each robot’s own record, not restated here. A part is priced only from the manufacturer’s published price for a part its own page lists for that machine, and costed only where a replacement interval has been established. Anything else is left unpriced rather than estimated.

Common questions
What readers ask about this comparison.
Q.
Which litter robot has clearer published running costs?
CatLink publishes one clear recurring figure: its activated-carbon filter costs about $180 a year at the manufacturer’s stated 60-day replacement cadence and $29.99 per set. PetKit prices its liner bags and odor cartridge individually but does not publish how often either needs replacing.
Q.
Do either require an ongoing subscription?
PetKit gates extended video history behind a paid Care+ subscription after a 30-day free trial. CatLink references a paid Cloud Storage Service on a separate FAQ page rather than the product listing itself.
Q.
Has either model shown hardware failures in the field?
Neither record turned up independent long-term failure data, and both released within the past 18 months. The only service issue documented for either is a handful of Trustpilot reviewers, relayed by bestiepaws.com, describing warranty-response delays for the PetKit unit.
Q.
What is the first real running cost an owner meets?
For the CatLink Scooper Pro Ultra, it is the activated-carbon filter, due at the manufacturer’s 60-day mark. PetKit’s odor cartridge and liner bags carry no published interval, so timing is left to the owner.
Q.
Are the two robots' disclosed costs directly comparable?
Not fully. CatLink’s $180-a-year filter is the clearest sourced recurring cost in either record, while PetKit’s consumables are priced per unit with no stated replacement schedule, which limits a like-for-like annual comparison.
