Self-Cleaning, With An Open Top Cats Actually Use

Many cats refuse the dark, enclosed drum of a typical robot box. This one stays open on top, so stepping in feels like a normal litter box, and the cleaning happens on its own.

OpenNest Self-Cleaning Litter Box

πŸ›‹οΈ An open top, not a closed drum

The wide, 16.5 inch open entry lets a cat see out while it goes, which calms the ones that balk at a dark tunnel. The roomy floor fits big cats and stiff seniors who struggle to climb into an enclosed unit, and it is rated for cats from 3.3 to 27.5 lbs.

🧹 It scoops so you do not

After your cat leaves, a short delay lets the litter clump, then the box sifts it into a sealed bin below that holds up to 30 days for one cat. You lift out a bag instead of scooping daily, and the aromatherapy box keeps the air fresh between empties.

πŸ›‘οΈ Built to stop for the cat

Infrared and weight sensors halt the cycle the instant a cat steps in or near, like a garage door reversing on contact. The gear uses non-toothed segments that limit how far it turns, so nothing can pinch a curious paw.

πŸ“ˆ Tracks weight and bathroom visits

It weighs your cat on every trip and logs how often and how long they go in the app. A steady drop in weight or a jump in visits often shows up before other signs, giving you an early nudge to call the vet.

The Worries, Handled

Quiet, Safe, Hands-Off

The usual reasons people hesitate on an automatic box are noise, safety, smell, and what happens when the wifi drops. Here is how each one is covered.

πŸ“ΆReliableAutomatic mode is the factory default, so it keeps scooping even if the wifi drops or is never set up

Works with plant, bentonite, mineral, and mixed litters. App control uses the free Tuya app over 2.4 GHz wifi, and the cleaning cycle keeps going without it.

  • Power adapter
  • Waste drawer

Key Settings

Buttons And Lights

  • Solid WiFi light means connected, slow blink means not connected
  • Hold Empty for 3 seconds to empty the drawer
  • Hold Clean for 1 second to start a cycle
  • All three lights flashing fast means an error, so reseat the waste drawer

Gamechanger! I've always used various 'manual' litter boxes, and whose turn it was to 'scoop' was a frequent stress point in my house.
