The Litter-Robot III Open Air, for example, jammed when we loaded too much litter or the wrong type of litter, and it malfunctioned when cat waste blocked the sensor (it mistakenly perceived the bin as being full). The main task of an automatic cat litter box is to scoop out pet waste, and the models we tested routinely failed at the task. Most of the automatic litter boxes we tested don’t live up to the hype.
SIMPLY CLEAN AUTOMATIC LITTER BOX FULL
(The ScoopFree Ultra’s rake system required just 1 minute, 10 seconds, while the Simply Clean’s conveyor belt took a full hour to scoop and sift litter into its waste bin.) In our tests the sifting process took 2.5 minutes, making the Litter-Robot the second-fastest of the automatic litter boxes we tested. The globe didn’t spill litter outside of the box like the design of the PetSafe Simply Clean did, nor did it stir the urine back into the litter bed like the PetSafe ScoopFree Ultra did. In our tests it removed more litter waste than the other models we tried because the spinning action helped remove gunky litter from the sides and base of the litter bed, whereas other models could sometimes miss those spots. The Litter-Robot’s globe rotates first counterclockwise and then clockwise to sift the litter bed and dump dirty litter into the waste receptacle. Installation process: I followed the manufacturer's instructions to set up each litter box, and I noted any challenges during the process.ĭespite its drawbacks, the Litter-Robot was one of the better automatic litter boxes in our test group at doing what it’s meant to do: scoop litter.Size: I reviewed the dimensions of both the litter boxes and the litter trays to see if they were on a par with those of our favorite traditional litter boxes.


And it got even louder when it scooped, with the arm making a banging noise as it shook off loose litter granules from the clumped waste. The CatGenie was the loudest litter box we tried: In our tests it loudly flushed water when clearing out the waste, an effect that could scare cats that are already skittish. Some cats (and people) may be put off by how loud automatic litter boxes can be-and if a cat has a negative association with a litter box, it might not use the box.
