Cecotec Pumba 8500 CleanKitty Smart (automatic litter box with weight tracking): our review

The waste drawer holds 9 L, a typical capacity for this category. That gives collected waste somewhere to go, but it does not tell you how long you can leave it between emptying. Your cats and their litter set that rhythm. Think of the drawer as breathing room in the routine. Emptying remains your job.

When the cat heads for the tray just after tea, the attraction of an automatic litter box is obvious. Nobody has ever wished the evening contained more scooping. We rate this model well placed for waste bin capacity, although a household sharing the tray should keep an eye on how quickly the drawer fills. Getting home from a weekend away is a nicer prospect when the person feeding your cat also knows when to empty it.

The Cecotec Pumba 8500 CleanKitty Smart measures 49 cm wide, 53 cm deep and 51 cm tall. Translate those measurements into the space you actually have: a stretch of floor across the bathroom, room extending towards your feet, and clearance beneath any shelf. Mark out the footprint before choosing its corner. An apparently empty patch beside the washing machine can be surprisingly busy when the cupboard opens.

Fit means more than getting the appliance into position. You will need to reach it for ordinary upkeep, so leave usable space around its home rather than filling every available gap. The dimensions help you plan that arrangement; they do not describe the room available to the cat inside. For a flat where the bathroom also stores towels and cleaning supplies, this is a practical decision before it becomes a furnishing decision.

Weight monitoring is a stated feature here. We like the prospect of having a weight reading to discuss with your vet when you have concerns about your cat. It gives that conversation a concrete reference. A reading cannot tell you why weight has changed. Changes in appetite or tray habits still call for a conversation with your vet, whatever the appliance records.

The manufacturer also specifies a weight sensor among the safety features. That is not a guarantee of your cat's safety, and it does not establish how the appliance responds when a cat enters. Does having a weight reading matter to you, or would you rarely give it another thought? Our view is straightforward: choose the extra you will use. Buy for the chores in your home, not the cleverness in the name. Smart lettering will not move the laundry basket or empty the drawer.

The Neakasa M1 Plus has a higher waste bin capacity of 11,23 L: more room for the waste that builds up between your visits to the drawer. The Neakasa M1 Plus is also better rated overall. That makes the Neakasa M1 Plus a clear alternative when extra room for collected waste matters most.

The PETLIBRO Luma has a higher waste bin capacity of 11 L, which makes it better suited to a household with several cats. PETLIBRO Luma has a similar overall score. More drawer space is useful when cats share a tray, although emptying frequency still depends on their use and litter. For a busy household, that distinction matters: the neighbour visiting while you are on holiday needs a workable routine, not an optimistic promise about how many days the drawer will last.
