EZIclean CATBOT K6i (automatic litter box app-controlled with built-in sealed waste drawer): our review

Safety is the non-negotiable criterion for any automatic litter box: a cycle that starts while a cat is still inside can cause a serious accident. The CATBOT K6i features multiple infrared sensors that detect an animal's presence inside the enclosure and immediately halt any cycle in progress.

This multi-sensor setup is more reliable than a single sensor, as it covers several areas of the unit at the same time. A single sensor partially blocked by litter can miss a presence, whereas redundancy reduces this risk. For households with curious cats, kittens, or anxious animals that sometimes stay inside longer than expected, this safety architecture is a concrete argument to weigh when choosing a model in this category.

Odor control is one of the central expectations of an automatic litter box, especially in apartments. The CATBOT K6i seals waste after each cycle in a hermetic compartment, cutting off airflow between the waste and the room. Unlike an open drawer, this system limits odor diffusion between 2 emptying cycles.

Actual performance depends on 2 variables that EZIclean does not officially disclose: the waste drawer's volume capacity and the recommended emptying frequency. A low-capacity drawer will need to be emptied more often to remain effective. For households with multiple cats or a highly active cat, we recommend asking EZIclean directly for the exact drawer capacity before finalizing your purchase.

The K6i records the number of your cat's litter box visits through its connected app. This basic tracking is nonetheless useful: a sudden change in frequency (very frequent visits with little urine, or a marked drop) is often an early sign of a urinary or digestive issue. Over several weeks, the history helps identify trends and provides concrete data to share with a vet.

The counter measures neither the cat's weight nor the amount of litter used, unlike models such as the Petkit Pura Max which include automatic weighing at each visit. For owners looking for in-depth health monitoring with weight charts, models with weighing offer more value. For trend tracking that is sufficient for a healthy cat, the K6i's counter does the job.

At 8.9 kg, the CATBOT K6i is one of the top-scoring models in our comparison on the stability criterion (9.1/10 in our scoring). This substantial weight means in practice that the unit will not shift under an active cat's movements when entering or exiting, or when pushed from the side. This form factor also reduces vibration noise during cleaning cycles.

The trade-off is that moving the unit for a deep clean or repositioning it in the room will be less convenient than with a 5 to 6 kg model. This is worth planning for if you expect to change the unit's location regularly. For a permanent installation, this form factor is clearly an asset.

The CATBOT K6i sits at the lower end of the mid-range connected automatic litter box segment. Its main reference competitor is the Petkit Pura Max, a significantly pricier model that adds automatic cat weighing at each visit, an active deodorization filter, and a weight history in the app. The price gap is primarily justified by this richer health tracking.

At the premium end of the market, the Litter Robot 4 offers a patented spherical design, integrated weighing, a dedicated filtration system, and an extended warranty. For a first purchase on a limited budget, the CATBOT K6i is a solid foundation. For multi-cat households or owners looking for detailed health monitoring, the step up to the Pura Max is worth serious consideration.
