Greesum Enclosed Self-Cleaning Cat Litter Box, 90L XL, App Control, Quiet | For Multi-Cat Homes — Anti-Pinch Safety Sensors, 6.5L Waste Drawer, Includes Litter Mat & 30 Waste Bags

LESS TIME SCOOPING. MORE TIME WITH YOUR CAT.
The best parts of having a cat — the head bumps, the purrs, the way they curl up next to you — don’t happen while you’re cleaning a litter box. Greesum takes the daily maintenance off your plate, so you can spend those extra minutes doing what actually matters: being with your cat.
We have 12 cats across our team. We built Greesum because we wanted the same thing: less chore time, more cat time.
ENCLOSED OR OPEN — DIFFERENT DESIGNS FOR DIFFERENT CATS.
Open-top automatic boxes and enclosed designs serve different needs. Open-top models work well for confident, outgoing cats who don’t mind an exposed space. But many cats — especially shy cats, anxious rescues, and former strays — feel safest in an enclosed, den-like environment. In the wild, a cat is never more vulnerable than when eliminating. A fully enclosed space gives those cats the security they need to relax and use the box consistently.
Beyond your cat’s comfort, there’s a practical difference: open tops let kicked litter scatter across your floor, while an enclosed globe keeps it contained. Greesum’s 90-liter fully enclosed design gives your cat the private, cave-like bathroom they instinctively prefer — and keeps your floors clean at the same time. Two benefits, one design choice.
We know the fear: trusting a motorized machine with your best friend. That’s why every Greesum deploys three independent sensor technologies, not just one:
Infrared Sensor — Dual Purpose: Detects your cat entering the box and pauses the cleaning cycle instantly. When the waste drawer reaches capacity, it triggers an alert reminding you to replace the bag.
Microwave Radar — Entrance Guardian: Activates upon contact with the entrance, stopping all motion the moment your cat touches it.
Living-Creature Radar — Internal Safety Net: Continuously scans inside the drum. If it detects any sign of life — a sleeping kitten, a curious second cat — rotation is locked immediately.
These three systems don’t compete. They cover different angles. Approach. Entry. Interior. Because your cat’s safety should never depend on a single sensor hoping for the best.
YOUR NEW ROUTINE: ONCE A WEEK. TEN SECONDS. DONE.
Greesum runs at 40 decibels — quieter than a whispered conversation. Your cat can do their business at 3 AM, and you won’t hear a thing. The app reminds you when the 6.5L sealed waste drawer is full (about once a week for 2 cats). You pull out the drawer, replace one bag, and push it back. Ten seconds. That’s your entire weekly litter box commitment.
No subscription fees for the app. No proprietary litter required. No hidden costs. Use any clumping litter with particle size under 15mm. A clean litter box, every single time your cat needs one.

🐱90L FULLY ENCLOSED GLOBE — PRIVACY YOUR CAT TRUSTS, FLOORS YOU’LL THANK US FOR. Unlike open-top boxes that scatter litter 3 feet in every direction, Greesum’s sealed 90-liter globe keeps 98% of kicked litter inside while giving your cat the private, secure bathroom they instinctively need — especially shy cats, anxious rescues, and former strays who refuse to use exposed boxes. Fits cats up to 33 lbs — Maine Coons, Ragdolls, and multi-cat households welcome. No more vacuuming around the litter box twice a day.
🐱3 SENSOR TECHNOLOGIES WORKING TOGETHER — YOUR CAT IS PROTECTED FROM EVERY ANGLE. Infrared sensor detects your cat entering the box and instantly pauses the cleaning cycle — it also triggers an alert when the waste drawer is full, reminding you to swap the bag. Microwave radar activates upon contact with the entrance, stopping all motion the moment your cat touches it. Living-creature radar scans inside the drum — if it detects any sign of life, rotation is locked immediately. Three independent systems, one shared mission: keeping your cat safe during every use.
🐱SMART APP CONTROL — NO SUBSCRIPTION, NO HIDDEN FEES, EVER. Switch between Auto / Scheduled / Manual cleaning modes from your phone via 2.4GHz WiFi. Track your cat’s usage patterns, receive push notifications when the waste drawer is full, and trigger cleaning remotely — all included, all unlimited, for the life of your device. Don’t want to use WiFi? The control panel on the unit works independently. No internet, no problem.
🐱40dB ULTRA-QUIET — YOUR CAT WON’T FLINCH, YOUR FAMILY WON’T WAKE UP. Operating at just 40 decibels — quieter than a library whisper — Greesum runs so silently you’ll occasionally check the app just to confirm it’s working. No grinding motors. No sudden noises that send skittish cats bolting out of the room. The 6.5L sealed waste drawer holds up to 7 days of waste for 2 cats. When it’s full, the app notifies you — swap one bag, 10 seconds, done. Your cat does their business at 3 AM. You sleep right through it.
