I’ll be honest — when I first heard about the Leo’s Loo Too, I assumed it was a knock-off. A globe-style self-cleaning litter box from a Chinese brand I’d never heard of, going head-to-head with the Litter-Robot 4? Seemed like wishful marketing. But after running both in my apartment for six weeks — Miso and his brother using them daily — I’ve changed my tune. Not completely. But enough to matter.
- ✅ Excellent app with per-cat usage tracking
- ✅ Active deodorizer spray is effective
- ✅ Wide globe entry (9 in) suits most large cats
- ✅ Strong value vs Litter-Robot 4 at ~$420
- ❌ Smaller waste drawer than Litter-Robot 4
- ❌ Deodorizer cartridge ~$12/month ongoing
- ❌ Customer support can be slow
What You’re Actually Getting With the Leo’s Loo Too
It’s made by PETKIT, a pet tech brand that’s been quietly building a solid reputation over the past few years. The design is globe-shaped, similar to the Litter-Robot, but with a few differences that actually show up in daily use. The entry opening is wider than I expected — my big boy Miso (just over 13 lbs) walks in without any hesitation. And the app is genuinely one of the better ones I’ve used in this category.
Setup took me about 20 minutes. Wi-Fi pairing was straightforward — 2.4GHz only, heads up if your router auto-merges bands. Once it’s connected, the PETKIT app gives you cycle logs, individual cat usage tracking by weight, and even an estimate of when you’ll need more litter based on depletion rate. That last feature sounds gimmicky. It’s actually useful.
The rotation is smooth. Not silent — nothing in this category is truly silent — but quieter than the Litter-Robot 3 Connect, and about on par with the Litter-Robot 4. Miso spooked the first two days, then stopped caring entirely.
What It Gets Right
Odor control
This surprised me. The Leo’s Loo Too uses a deodorizer spray that triggers automatically after each cycle — you can set the frequency — plus a carbon filter in the globe. In a small apartment bathroom, I genuinely stopped noticing any smell within a few days. Whether that’s better than the Litter-Robot’s approach (sealed drawer plus carbon filter, no active spray) is hard to call definitively. What I can say is that it works, and works well for one or two cats.
The app
I spend more time in the PETKIT app than I’d like to admit. The weight-based cat ID is surprisingly accurate — Miso is 13.2 lbs and his brother is 10.8 lbs, so they’re distinct enough that the app correctly logs most visits. Two cats within a pound of each other would confuse it. But real-time alerts, health flags for unusual patterns, and remote cycle triggers all work reliably.
Price
Around $400–$450 depending on sales. That’s $250–$300 less than the Litter-Robot 4. That gap is hard to ignore when the core cleaning performance is this close.
Where It Falls Short
The waste drawer is smaller. With two cats, I’m emptying it every 4–5 days instead of the 7–10 days I get with the Litter-Robot 4. Not a dealbreaker, but worth knowing before you buy.
The deodorizer cartridge is a consumable — lasts about 30 days, costs $10–$15 to replace. That’s $120–$180 per year on top of everything else. The Litter-Robot doesn’t have this ongoing cost; it just needs carbon filter replacements every few months.
And customer support is hit or miss. PETKIT is improving, but I’ve seen enough user reports of slow response times and frustrating warranty claims that I’d mention it. Litter-Robot (owned by Whisker) has much better US-based support infrastructure. If you’re the kind of person who needs that reassurance, it’s a real factor.
Litter-Robot 4: Still Worth the Premium?
The Litter-Robot 4 launched in late 2022 and fixed most of the complaints about the 3 Connect — quieter, larger waste drawer, built-in scale, OdorTrap system, sleeker app. It’s $699. That’s real money.
The build quality is noticeably better. Thicker plastic, more refined mechanisms, years of iteration behind it. For cat owners who’ve burned through two or three cheaper boxes that broke within a year, that track record is worth something. The liner bag system for the waste drawer is also genuinely superior — emptying the Litter-Robot takes under a minute and barely requires touching anything. The Leo’s Loo Too drawer is a direct-dump situation. Fine, but less elegant.
Honestly though? The Litter-Robot 4 isn’t dramatically better at the actual job of cleaning. Both sift, both rotate, both remove waste within minutes. The gap is real but narrower than the price difference suggests.
Head-to-Head: The Actual Differences That Matter
Price: Leo’s Loo Too wins, clearly. $400–$450 vs $699 is a meaningful difference.
App: Leo’s Loo Too has a slight edge. PETKIT’s app is more feature-rich and updates frequently. Litter-Robot’s app is solid but has had reliability issues that come up in reviews more often than I’d like.
Odor control: Genuinely close. Different methods, both effective. The Leo’s Loo Too’s active spray gives you a little extra buffer but adds ongoing cost.
Waste capacity: Litter-Robot 4 wins, especially with multiple cats.
Build quality and support: Litter-Robot wins, not close.
So Which One Should You Buy?
One or two cats, budget under $500: get the Leo’s Loo Too. It’s not a compromise — it’s genuinely good, and the $250 you save is real. I’ve had both boxes running in my apartment and I don’t miss the Litter-Robot 4 when I’m using the Leo’s Loo Too day to day.
Three or more cats, or you want the most reliable product with the best support, or you just want to buy once and stop thinking about it: get the Litter-Robot 4. The larger waste capacity makes a bigger difference than people expect with multiple cats. And knowing there’s solid warranty support if something goes wrong is worth something.
One thing I’d add: if you have a large cat (15 lbs+), check the entry opening on both before committing. The Leo’s Loo Too is fine for most large cats, but truly massive Maine Coons might find it tight. Miso manages fine at 13 lbs. Your mileage may vary.
The Verdict
The Leo’s Loo Too isn’t better than the Litter-Robot 4 across the board. But it’s better value for most households, and the gap has closed enough that it’s a real decision now. A year ago I’d have told anyone to just buy the Litter-Robot and not think about it. Now I’d actually ask how many cats you have first.
