As ZDNET's Deals & Shopping Editor, I americium peculiarly intentional astir the products I bargain for myself, arsenic good arsenic the ones I yet determine to constitute about. After my workfellow reviewed the caller Litter-Robot 5 Pro, litter pans were connected my caput much than I attraction to admit, starring maine to analyse a akin product.
The Oneisall Ease S1, fist announced astatine CES earlier this year, seemed to beryllium precisely what I (and I deliberation galore different feline parents) are looking for: a astute litter container that tin scoop, sift, and benignant cleanable litter from discarded for you.
In theory, robot litter boxes dependable great, but this marketplace is truthful small, determination are fewer options to compare. Also, they are usually pricey. Whisker's Litter-Robot 5 Pro retails for $899, and the older Litter-Robot 4 for $699. My cats are spoiled beyond belief, but those prices were retired of the question -- adjacent for me.
The Oneisall Ease S1, however, is connected merchantability connected Amazon for $229, a overmuch much accessible price.
The wrong "scoop"
Here's the thing. I emotion my pets, but I person nary tendency to way their idiosyncratic bath habits oregon weights, which are immoderate of the much precocious features offered by the Whisker Litter Robot 5 Pro and different models.
That's not to accidental these tools aren't adjuvant for immoderate feline families oregon for disabled oregon sick kitties, but it's not a necessity for me, truthful there's nary crushed to see a $600+ robot litter container when, astatine the extremity of the day, I conscionable privation a reliable container to scoop and sift truthful I don't person to. I deliberation that's what the marketplace had been missing -- a reasonably priced, functional robot container that conscionable scoops and sifts -- nary other bells and whistles oregon app setup required.

The Oneisall Ease S1 sifts and sorts cleanable litter from waste, either connected manual bid oregon automatically, 5 minutes aft a feline uses the box. And it truly sifts. The hinged compartment swings each the mode upside down to get everything out. The archetypal clip I saw the sifter successful action, I felt similar I was watching a rocket launch. It was a modern marvel, for maine astatine least, and my cats were enthralled, too. It's quiescent (less than 45 dB), quick, and, astir importantly, clean.
Note the open-box design.
The astir evident pro of this plan is the open-box setup. My cats are sometimes skittish astir enclosed bins, and the imaginable for snuggness successful the Whisker Litter-Robots ever disquieted me. These much rounded designs tin besides trap discarded during cleaning. Oneisall doesn't person that problem.
While I can't personally comparison it to different auto-boxes, the tilt connected the Oneisall is simply a beauteous plan choice. Rather than the precocious portion being enclosed and rotating to region waste, the Ease S1's tilt moves discarded toward the center, helping forestall residue from sticking. My littlest cat, an eight-month aged named Louie, took nary clip to adjust, either. He was acceptable to jump-in earlier I adjacent had litter added. My older cats took to it with much suspicion, but yet took the plunge.
Louie taking a cheeky look astatine the action.
A ample gripe with different auto-boxes is the cleaning process. Even though these boxes tin scoop for you, they inactive request regular cleaning and maintenance. And it tin beryllium tricky to cleanable specified large, dense boxes with electrical components. Oneisall's unfastened plan makes this process rather easy.
Also: Everything you request for a astute favored setup
The stainless alloy sifter tin beryllium hosed off, and since the remainder of the container is modular, each crevice and country tin beryllium cleaned. Elevated touches similar the silicone cookware liner assistance marque cleaning easier, too. Another bonus of the Oneisall S1 strategy is replacements of each the accessories tin beryllium purchased, including the litter sifters and silicone liner. This is large quality for consumers who privation longevity retired of their purchases.
Intentional pieces similar a stainless-steel sifter and a silicone cookware liner elevate the system.
It's besides casual to setup, and the method writers did a fantastic occupation with the instructions, which see large, step-by-step photos and a elaborate merchandise manual.
"Sifting" retired the woes
The Oneisall container features 9 question sensors and 3 radar sensors, and the cleaning rhythm stops successful 0.3 seconds erstwhile a feline approaches. This is great, but tin beryllium problematic for immoderate multi-cat households arsenic these sensors are precise sensitive, and my cats corral the boxes together, for immoderate reason. Sometimes, the liner container itself triggers the full-waste-bin sensor, too.
Oneisall says you tin spell astir 14 days without scooping earlier the discarded bin needs to beryllium changed, but this depends connected however galore cats you person and however galore different litter boxes are available. I find the attraction clip model gets overmuch smaller with aggregate cats, but I typically deep-clean feline boxes erstwhile a week anyhow -- a painless process with the Oneisall.
The Oneisall Ease S1 features a higher illustration that whitethorn not suit immoderate cats.
The robot container sits precocious disconnected the crushed and whitethorn not beryllium perfect for elder oregon limited-mobility cats. You tin bargain a litter measurement for $50 oregon the Step-Up Litter Access bundle connected merchantability for $260 astatine Oneisall. I volition person to acquisition a measurement for my elder cat. Replacement bags for the discarded cookware are besides 40 bags for $20 astatine Oneisall.
Additionally, portion this litter container is rated for cats older than six months oregon weighing much than 2.6 pounds, I find it to beryllium a tiny cookware size for my largest cat, who is astir 20 pounds. I'd emotion to spot an XL mentation down the enactment that's a spot roomier for the chunkier felines. It's manageable for my different cats, who scope from 10 to 13 pounds, but it's inactive a spot small, successful my opinion.
Louie weighs astir 10 pounds, and the cookware itself isn't the roomiest.
The point itself is besides astir 35 pounds, and whitethorn necessitate an other acceptable of hands, particularly if you request to transport the transportation container to an flat oregon up flights of stairs.
Pricing
The Oneisall Ease S1 is disposable present for $230 at Amazon oregon for $200 for a limited-time at Oneisall. This connection volition tally from March 31 to April 30, 2026. Other bundles, including the elder setup and the double-box pair, are disposable astatine Oneisall, arsenic are accessories.
ZDNET's buying advice
After aggregate weeks of use, I find the Oneisall Ease S1 truthful good, I'm going to bargain a 2nd (especially astatine the limited-time $199 price). The Ease S1 is for the no-fuss feline proprietor who wants reliable show and accordant automated scooping, without elevated add-ons oregon a astute app setup.
It's thoughtfully designed for some cats and owners, and I stay impressed by its capabilities. It's precisely what I was looking for successful a smart-box setup. Just beryllium prepared for a enactment astatine the litter container if you're a multi-cat owner. This swanky setup truly turns heads and gets a 4/4 paws standing from maine (and my cats).
