Description
Meet the Oneisall Self-Cleaning Litter Box — the open-top automatic box that finally puts your cat’s comfort first. Instead of a scary enclosed drum your cat has to climb inside, it’s a wide, bright, walk-in tray that large, senior, and timid cats actually trust.
About five minutes after your cat is done, a stainless-steel sifting screen rakes through the litter, separates the clumps, and seals them into an 11L odor-locking waste drawer — then the litter levels out, fresh and ready for the next visit. The generous bin holds roughly two weeks of waste for one cat, so daily scooping becomes a twice-a-month, 30-second chore.
All the hands-free convenience of a $700 drum box, plus open-top safety it structurally can’t offer — at a fraction of the price.
What’s Included
- Open-Top Self-Cleaning Litter Box — spacious walk-in tray, no enclosed drum
- Sealed 11L Waste Drawer — odor-locking, holds ~14 days for one cat
- Detachable Stainless-Steel Sifting Screen — pops out and rinses clean
- Silicone Liner & Litter Mat — less sticking, less tracking
- AC Power Adapter & Quick-Start Guide — app-free, ready in minutes
How It Works
The Ease S1 is a semi-automatic open-top sifter, in four simple steps:
- 1. Cat uses Ease S1 — your cat does its business in the open, low-stress walk-in tray.
- 2. Wait ~5 minutes — the box pauses so the litter can harden into solid, scoopable clumps.
- 3. Auto-cleaning begins — the stainless screen rakes the litter and seals clumps into the 11L drawer.
- 4. Litter levels & resets — fresh litter falls back, leaving a clean tray, completely hands-free.
A 12-sensor safety system auto-pauses the cycle in about 0.3 seconds if your cat steps near. The Standard model is fully app-free; no Wi-Fi required.

Truly Easy Cleaning, Inside and Out
The Oneisall is fully modular — the stainless-steel sifting screen and silicone liner pop out and rinse clean in seconds, with no hidden corners to scrub like an enclosed drum box. Between rinses it does the work for you: about five minutes after each visit it sifts the clumps and seals them into the 11L odor-locking drawer, holding roughly two weeks of waste for one cat. Empty it in about 30 seconds, twice a month — that’s the whole chore.
Built-In Safety, Open-Top Comfort
A 12-sensor safety array (9 motion + 3 radar) auto-pauses the cycle in about 0.3 seconds the moment your cat steps near, and the open top means no dark, cramped drum to spook timid, senior, or large cats.
Unbox & Plug In
Snap it together in about ten minutes — no tools, no app. Add litter, plug it in, and it’s ready to go.
Your Cat Settles In
The open, walk-in tray feels natural fast — even timid, senior, and large cats step right in with no enclosure to fear.
No More Daily Scooping
About five minutes after each visit it sifts and seals the clumps away, leaving a fresh, clean box every single time.
Empty Once, Then Relax
Swap the sealed 11L drawer in about 30 seconds, roughly twice a month. That’s the entire litter chore — handled.

Customer Reviews
It cleans itself about five minutes after my cat is done and seals everything into the drawer, so I just swap the bag every couple weeks. I haven’t touched a scoop in over a month and the box always looks fresh.
I have a 16-lb Maine Coon and a chunky tabby, and the open top means neither feels boxed in. They both took to it instantly — so much roomier than the dome model we returned.
The stainless sifter pops out and I just rinse it in the sink — no waste stuck in hidden corners like my old rotating box. The sealed drawer keeps the smell completely locked away.
It fades into the background under 45 dB and my nervous cat doesn’t even flinch when it cycles. My old auto box sounded like a garbage disposal and terrified both cats.
Solid shell, a real stainless-steel sifter, nothing flimsy about it. It looks more like a $700 box than what I paid, and it doesn’t look out of place in my living room.
No more morning scoop, no more nightly check. Two-week hands-free stretches are a total game changer with a busy schedule, and setup took about ten minutes with zero tools.
