Which litter robot has clearer published running costs?

The CatLink Scooper Pro Ultra's record prices its carbon filter at $29.99 every 60 days, $182.44 a year, and also prices a $19.99 sift screen without an interval. The PetKit Purobot Max Pro 2's record prices two deodorizer cartridges at $6.66 each, one every 30 days and one every 45-60 days, $121.61 a year together. Bin liners are priced on both, and the PetKit's $39.99 litter pad too, all without an interval.

Do either require an ongoing subscription?

Neither needs one to clean. The PetKit Purobot Max Pro 2's optional PETKIT Care+ plan keeps 30 days of video history, and its record holds no US price for it. The CatLink Scooper Pro Ultra's optional cloud storage plan is free for a year, then $1.90 for 30 days or $6.90 for 365 days with 1-day playback, or $2.90 and $19.90 for the same terms with 7-day playback.

Has either model shown hardware failures in the field?

Both were released in 2025: the CatLink Scooper Pro Ultra in May and the PetKit Purobot Max Pro 2 in September. The failure points on both records are held until an outside source reports one, so none is shown here yet.

What is the first real running cost an owner meets?

On these records, the first priced recurring costs are the PetKit Purobot Max Pro 2's deodorizer cartridge, $6.66 every 30 days, and the CatLink Scooper Pro Ultra's carbon filter, $29.99 every 60 days. Owners of both also empty the waste drawer weekly, 8 L on the PetKit and 13 L on the CatLink, and fit a fresh liner. Neither paid video plan is needed to clean, and the CatLink's is free for its first year.

Are the two robots' disclosed costs directly comparable?

Partly. On list prices of $599.99 for the PetKit Purobot Max Pro 2 and $599 for the CatLink Scooper Pro Ultra, the records price a year of parts at $121.61 and $182.44, at least $964.82 and $1,146.32 over three years. Bin liners and sift screens carry no interval on either record, so they sit outside both figures.

Same on both: the cleaning cycle and live camera view need no paid plan. Only stored video history is sold as a plan.

In a front hall, a new white CatLink litter box stands on the base of its opened delivery carton, with the two spare sift filters and a deodorizer refill that came in the box laid out on the hall bench beside it.
