  1. 1

    PETKIT Pura Max 2

    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 · From £479.00

  2. 2

    PETKIT Purobot Max Pro 2

    The high-tech flagship, adding an AI camera with cat facial recognition and health tracking on top of strong cleaning and a large opening. Excellent for multi-cat health monitoring, though you pay for the camera tech and the app can lag.

  4. 4

    HomerunPet CS106

    A feature-packed unit that includes a self-refilling litter system as standard, something rivals charge extra for. Very good scooping thanks to a large catcher. Strong value for the features, if from a less familiar brand.

    Best for: Multi-cat homes wanting auto-refill included · From £499.00
