Martin Sellier 76L (automatic litter box 76 L globe, connected and quiet at 40 dB): our review

A roomy waste drawer is a useful starting point when the aim is fewer appointments with the litter scoop. With 13 L for collected waste, this enclosed tray has substantial storage that may leave longer gaps between emptying. Its waste capacity is among the best on the site. That matters in a household where cats share the tray and the contents accumulate rather faster than anyone would prefer.

Will you get home from a weekend away without a drawer to empty? That depends on your cats and the litter used, so capacity is breathing room, not a timetable. The removable waste bin gives you a separate container to take out when that job comes round. We like the generous provision here, but cleaning is semi-automatic: manual intervention remains part of ownership. Your cat can retain its supervisory role. Someone still has to do the work.

At 55 cm wide and 55 cm deep, the appliance needs a dedicated square of floor. In a utility room, that could mean moving the basket currently occupying the corner. In a small bathroom, it could mean admitting that the spot beside the washing machine already has enough going on. Measure before rearranging your home around a hopeful guess.

The 66 cm height matters too: this is an upright enclosed appliance, so check any shelf above its intended position. Leave practical access to the removable waste bin rather than fitting the body into a space so tightly that emptying becomes furniture removal. Floor space and working space are different things. We would favour a position you can reach easily during ordinary chores. A generous drawer loses some appeal if getting it out means shifting the laundry every time, especially when the washing pile has already annexed the room.

Here is the practical reservation: the 32,5 cm entrance is a high step that an older or stiff cat may find harder to manage. Does your cat already pause before climbing into its current tray? That hesitation should carry more weight in your decision than the prospect of fewer scooping chores. Access is fundamental.

The manufacturer gives a permitted weight range from 1,5 kg to 12,5 kg, so the design is also intended for larger cats within those limits. The 25 cm opening gives you a concrete entrance width to consider alongside your cat's build; a weight limit alone cannot describe how comfortably a cat will pass through.

The UBPet C41 is better suited to an older cat, with a lower entrance step of 20,3 cm. The UBPet C41 has a lower waste bin capacity of 6,7 L. Choose around the cat's access needs before deciding how much waste storage your household wants.

Silica is the verified compatible litter type for this model. That is a buying decision in itself if your cupboard currently holds something else. Clumping litter compatibility is not confirmed here; if keeping clumping litter matters to you, ask the retailer before ordering. There is little point choosing a convenient appliance around a litter routine you do not want to change.

Keep replenishing silica and emptying the removable bin in your household routine. Semi-automatic cleaning does not remove those jobs, and it should not be read as a promise that the tray manages itself while you are away. A neighbour feeding the cat still needs clear instructions about what requires attention. We would keep those instructions practical: use the compatible litter, look at the waste bin and leave time for upkeep. The appeal is reducing the burden of a familiar chore, not handing responsibility for it to the cat.

Weight monitoring adds an observation to the cleaning routine if you want to follow your cat's recorded weight. It is not a health tool. A change that concerns you, or a shift in toilet habits, belongs in a conversation with your vet rather than an interpretation of appliance readings. A reading needs context. That applies especially when household cats share the same tray.

The manufacturer names a weight sensor as a safety feature. That is a stated feature, not a guarantee of your cat's safety. The specified noise level is 40 dB during the cleaning cycle: expect a sound to consider when choosing a spot near the room where you watch television after tea. The figure does not tell you exactly how noticeable the cycle will be through your bathroom door. Placement deserves thought before the appliance takes up residence.
