Overview
Scooping automatically after each visit, this oneisall box sifts clumps into a sealed waste drawer and pauses whenever its sensors detect a cat. The open top suits large cats, and every module detaches for rinsing.
Full disassembly for rinsing solves the trapped-waste problem of many automatic boxes. Several sensor types guard against scooping with a cat inside. Tofu litter needs an optional guard.
Who it's for
Big cats that dislike hooded boxes and owners who want to wash the whole unit suit the open design. Tofu or pellet litter users need the add-on guard first.
Pros and cons
- Open top suits big cats
- Several sensors protect cats
- Rinses clean with no tools
- Large drawer cuts emptying
- Tofu litter needs extra guard
- Open top lets litter scatter
- Needs a power outlet
Performance notes
Scooping accuracy depends on clumps forming firm enough to sift through the stainless guard. Sensors pause the cycle when a cat approaches and resume once it leaves. Drawer capacity sets how often you empty it.
