I’ll be upfront: when the Como Litter T20 Pro landed on my radar I was skeptical. Another globe-style self-cleaning box from a brand I didn’t know, promising Litter-Robot performance at a lower price. I’ve heard that pitch before. But after six weeks of Miso and his brother using it daily, I’ve got a real opinion on it — and it’s more positive than I expected.
- ✅ Good clump separation with clumping clay
- ✅ Wide 9.5 in globe entry
- ✅ Solid odor control with carbon filter
- ✅ Competitive price when under $350
- ❌ App less polished than PETKIT or Whisker
- ❌ Direct-dump waste drawer (no liner bags)
- ❌ Support infrastructure less established
First Impressions: It’s Bigger Than You Think
Out of the box, the T20 Pro is physically large. The photos undersell it. I had to rearrange my bathroom to fit it comfortably, which — fair warning — is something worth measuring for before you order. The plastic feels reasonably solid, not the cheap hollow feeling you get from some budget competitors. Assembly took about 15 minutes and required no tools.
The globe entry is around 9.5 inches — generously sized, and notably wider than some rivals at this price point. Miso walks in without any hesitation, and he’s not a small cat. Setup connects to Wi-Fi (2.4GHz only, same limitation as most in this category), and the app walks you through the pairing process without much drama.
How It Cleans: The Day-to-Day Reality
Sifting
The T20 Pro uses a timed rotation — you set it to trigger 5, 10, 15, or 30 minutes after your cat exits. The rotation is smooth and quiet. Not silent, but quieter than the Litter-Robot 3 Connect and roughly comparable to the Leo’s Loo Too. Some owners report the motor gets slightly noisier after a couple months of heavy use, but I haven’t hit that point yet and it’s still well within acceptable range.
Clump separation is good with standard clumping clay. The globe angle pushes clumps cleanly into the waste drawer without breaking them up — broken clumps mean fine waste contaminating your clean litter, which is a problem with some cheaper globes. The T20 Pro handles this well. Crystal litter and tofu litter both technically work, but the manufacturer recommends clumping clay and in my experience that’s where it performs best.
Odor control
Better than I expected. The waste drawer seals reasonably tightly, there’s a carbon filter slot, and the globe has a deodorizer port that takes Como Litter’s own tablets (or third-party activated charcoal tablets — both fit). Room smell between cycles is low for a single cat household. With two cats it starts to push; I empty the drawer every 4–5 days and that keeps it manageable.
One thing I’ll flag: the drawer is a direct-dump system, not the liner bag setup that Litter-Robot uses. Emptying it is fine — just slightly less clean than peeling out a tied bag. You’ll notice it at emptying time.
The App: Functional, Not Fancy
The Como Litter app has improved with recent updates. Usage logs, cycle history, manual cleaning triggers, weight-based cat ID — it’s all there. Push notifications work reliably. The safety sensors that stop rotation if a cat re-enters during a cycle are responsive; I’ve seen them trigger correctly when Miso got curious mid-cycle.
But the app feels functional rather than polished. No litter level estimation, basic analytics, interface that works without being enjoyable to use. It does the job. If you’re used to the PETKIT app on the Leo’s Loo Too or the Whisker app on the Litter-Robot 4, the Como Litter app will feel a step behind. Not broken — just not refined.
T20 Pro vs. The Competition
vs. Leo’s Loo Too (~$400–$450): This is the comparison that matters most. They’re close in price and performance. The Leo’s Loo Too has a better app and an active deodorizer spray. The T20 Pro has a slightly larger globe opening. Honestly? When they’re similarly priced, I’d give the Leo’s Loo Too a narrow edge on features. When the T20 Pro is on sale under $350, the math shifts.
vs. Litter-Robot 4 (~$699): The Litter-Robot 4 is more expensive, better built, has a superior liner system, a larger waste drawer, and more established US-based support. The T20 Pro closes the gap on core cleaning performance but isn’t in the same league on build quality or after-sales support.
Who Should Buy the T20 Pro?
One or two cats, budget in the $300–$400 range, and you want a globe-style smart litter box without paying Leo’s Loo Too or Litter-Robot prices. That’s the sweet spot. For that use case, it’s a legitimate buy and I’d recommend it without major reservations.
I wouldn’t buy it if you have three or more cats — the waste drawer will become a daily frustration. And if long-term support reliability matters to you, the Litter-Robot’s track record is meaningfully stronger.
Verdict
The Como Litter T20 Pro earns its hype — partially. It cleans well, handles odor competently, and the app does what it needs to. It’s not going to unseat the Litter-Robot 4 or clearly beat the Leo’s Loo Too on features, but it belongs in the same conversation for one-to-two cat households watching their budget.
Under $350: easy recommendation. Above $400 and the Leo’s Loo Too is the stronger choice. Check the current price before you decide.
