Oneisall has just announced its new product at CES 2026 , a new automatic litter box. It’s called the Oneisall Ease S1, and it features an open-top design. This litter box is actually quite interesting, and it could make your life just a little bit easier.
The Oneisall Ease S1 is an automatic litter box with an open top
The Ease S1 is equipped with a modular stainless-steel litter sifting screen that can be removed quite easily. That way, you can clean it properly without making a mess. The litter chamber is wrapped in a detachable, soft silicone liner, which is supposed to provide protection all around.
This setup should prevent cat urine from leaking through the edges and into the lower chamber of the litter box. That silicone liner that we’ve mentioned also helps reduce odors, says Oneisall.
This entire litter box is modular, actually. That goes for the litter sifting screen, upper cover, litter chamber, and bottom base. You can detach all of those and clean them without a problem whatsoever.
It’s powered by a high-torque gear motor, which is not loud at all
The Oneisall Ease 1 is powered by a 238 238 Kgf·cm high-torque gear motor, which is paired with a vertical slat sieve system. That setup performs a controller 165-degree rotation to separate clean litter from waste and drop it directly into the sealed compartment.
That’s the main feature of this whole litter box, and hence the ‘automatic’ mention at the start. This thing keeps clean litter at your cat’s reach, while it gets rid of the waste. You can simply remove it from the sealed compartment when you want.
Just to be clear, the torque and speed are “carefully tuned,” says the company, so that the product delivers “consistent, gentle, and quiet cleaning cycles”. That goes even for households that have more cats.
Open-top design is a major benefit
The open-top entry for cats is another benefit. Many cats avoid enclosed litter boxes , as they feel confined, and so does mine. So this system would actually be perfect. The rectangular open-top layout is actually quite spacious. It provides cats with about 30% larger point of entry than typical rectangular designs.
The Oneisall Ease S1 has a dual-layer noise-dampening motor that keeps operation under 45 decibels. That was it won’t scare off your cats or anything like that, and the noise won’t bother you either.
Cat safety is one of the most important aspects here
Oneisall also highlighted the safety of this litter box. It combines radar, weight, and infrared sensors into a real-time monitoring system to track your pet’s movement. If a cat approaches or steps inside during a cleaning cycle, the system will stop itself in only 0.3 seconds.
The company’s patented pull-string waste bag lets you seal the compartment with just one hand in three seconds. So you can keep your hands completely clean while cleaning out the waste.
The Oneisall Ease S1 litter box is priced at $229.99, while it measures 20.1 x 23.03 x 21.97 inches. Oneisall did not mention when it will become available, but it’s possible it’s already listed on the company’s website.
