The one that buys back an hour a week · review
An open-topped drum box for cats that refuse enclosed machines, with the widest stated weight range here — up to 15 kg — and 6 infrared plus 4 weight sensors watching the cycle.
The bottom line The box for a big cat or a wary one. You trade some odour containment and a couple of decibels for a shape cats accept quickly and a genuinely large waste bin.
A drum box with the top left open. There is no hood and no tunnel: the cat steps in as it would on a tray, and the drum turns after it leaves.
The most expensive failure in this whole category is a box the cat refuses. Enclosed drums ask a cat to walk into a tube with a floor that has moved before; some cats never accept that. An open machine looks like the tray they already use, which is why Neakasa leads with the design rather than with the electronics.
Cats up to 15 kg — the widest range on this page. A 7.17-litre litter chamber and an 11-litre waste bin, together giving up to 14 days. Six infrared sensors and four weight sensors, which stop the cycle on contact rather than after it. Noise at or below 50 dB, and a one-year warranty.
Odour containment. A sealed drum keeps smell in the waste box between cycles; an open one cannot, and relies on the cleaning cycle happening promptly instead. And litter travels: what a hood would have kept inside ends up on the floor around the machine, so this is a box for a utility room rather than a hallway.
Auto, manual, timer and empty. The empty cycle is the one that matters on a drum: it turns the whole chamber out when you are changing litter, instead of you tipping 7 litres of clay into a bag by hand.

Because a significant number of cats will not use an enclosed one. A cat that has always used an open tray sees a hooded drum as a tunnel with a moving floor, and refusal is the most expensive outcome in this category. If your cat is at all cautious, an open design is the safer purchase even though it contains less odour.
It is Neakasa’s stated figure, and it is the highest here — most boxes on this page stop at 8 to 12.5 kg. For a Maine Coon or a large mixed breed, that headroom is the specification that decides between this and everything else.
Neakasa gives up to 14 days from the combination of a 7.17 L litter chamber and an 11 L waste bin. As always that assumes one cat; with two, halve it, and with an open design expect to sweep around the box more often than you empty it.
