Comparison / Enclosed vs open-top
Litter-Robot 4 vs Neakasa M1 Plus: the design argument, settled by your cat
Research updated November 10, 2026 / Clean Litter Lab notes
Most comparisons in this category argue about features. This one is about a prior question: will your cat walk into an enclosed globe at all? The Litter-Robot 4 is the best enclosed machine in the catalog. The Neakasa M1 Plus is the best argument that enclosure is optional. Your cat's temperament decides before any spec does, and the specs below then confirm or complicate that decision.
Note on naming: the live catalog's current Neakasa listing is the M1 Plus bundle; a plain M1 appears only as a renewed listing, so the Plus is the verified side of this comparison.

Acceptance first
Owner discourse is unambiguous on one point: cats that refuse enclosed boxes - a real and common population - accept open beds at a far higher rate, because the geometry matches the tray they know. If your cat already uses an open tray happily and has never met a hood, the Neakasa removes the single biggest adoption risk in the category. If your cat likes dens and covered boxes, the globe's cave stays an advantage, not a barrier.

Globe and bed, side by side
Questions owners actually ask
Which controls odor better?
The enclosed globe, by physics: waste and bed are behind a door. The Neakasa closes most of the gap with its brush-strip bin seal, and owners rate its odor performance surprisingly well - but a sealed globe in a studio flat is still the safer nose bet.
Which fits a Maine Coon?
The Neakasa, rated to 33 lb with an open bed to turn in. The Litter-Robot 4's globe suits most cats but the entrance and interior are the constraint for the biggest breeds.
Which is safer?
Both pass our standard by different routes: the Whisker by a documented sensor stack inside an enclosure, the Neakasa by removing the enclosure entirely and adding infrared detection and a rotation-limiting gear.
Which app is better?
Whisker's. Weight per visit, litter and waste levels, and a mature ecosystem. Neakasa's app covers modes and per-cat activity competently.
I can only buy one and my cat is anxious. Which?
The Neakasa. Anxiety plus a new enclosed machine is the refusal pattern our transition guide exists to fix, and the open bed skips most of it.
