PETKIT Pura Max 2 review
Published 20 June 2026
The value champion, delivering most of the Litter-Robot 4's performance for a few hundred pounds less. Quiet, large 76L capacity, triple odour control and good app features. A loose-fitting liner and more variable support are the trade-offs.
Best for: Most UK buyers, and multi-cat homes wanting capacity

Common questions
How does the Pura Max 2 compare to the Litter-Robot 4?
It delivers around 90% of the performance for a few hundred pounds less, with similar quietness and odour control and larger capacity. The trade-offs are a 1-year warranty versus two, more variable customer service, and an occasionally loose liner.
Is it good for multiple cats?
Yes, its large 76L capacity and deodorising suit busy multi-cat households well, one of its main strengths over smaller units.
What is the liner issue?
The liner system can fit loosely, which occasionally causes jams. Keeping spare liners on hand and seating them carefully resolves it for most owners.
