Robot Litter Boxes

How to read this table

Every value in the table above is the manufacturer's own published figure, copied from the maker's product page, spec sheet or manual. A cell that reads Not published means the maker has not stated that figure. In this category the gaps cluster in exactly the places buyers ask about — entry height, drawer volume in litres, and the weight at which the cycle triggers — so an unpublished value is often the most useful thing on a row.

Two published booleans deserve reading before any price: whether the box requires the maker's own litter, and whether the maker rates it for more than one cat. Both change the long-run cost and the day-to-day suitability more than the sticker price does.

What actually decides which litter box fits

Start with the cat, not the box. Every maker publishes a cat weight range, and it exists because the sensor has to detect the cat to hold the cycle. A kitten under the minimum, or a large cat over the maximum, is outside the design envelope the maker will support. Entry height and internal footprint matter for older or arthritic cats, and for cats that simply refuse a narrow opening.

Then the running cost. Boxes that take standard clumping litter can be fed from any supermarket bag. Boxes built around the maker's own crystal trays or cartridges carry a subscription-shaped cost that the purchase price hides entirely, and that cost continues for as long as you own the box.

Waste drawer capacity sets how long you can go between emptyings, and it is the figure that changes most in a multi-cat home, where the drawer fills several times faster. Published cycle delay tells you how long after the cat leaves the box the rake or drum moves — a longer delay is the safety-conscious setting, and a maker that publishes it is telling you it thought about the case.

Health and app features vary in substance. Some units record visit counts and per-cat weight; others only report that a cycle ran. Where a maker publishes health monitoring, this table records that it exists; what precisely is measured is stated on the model's own page rather than flattened into a single yes.

Safety and recalls in this category

Automatic litter boxes are motorised enclosures that a pet walks into, so recall status is tracked as a first-class field on every model here. No brand in this table currently carries a verified official recall, and each row records the date that was last checked rather than implying it is permanently true.
