Leo’s Loo Too: The Honest Take
Leo’s Loo Too is made by Petkit, a Chinese pet tech brand that’s been quietly making solid products for years. It looks premium, works well most of the time, and costs about $150 less than the Litter-Robot 4. For a lot of cat owners, that’s enough reason to buy it. Check out our full Leo’s Loo Too review for a deeper dive.
What Leo’s Loo Too Does Well
- Price: At around $549, it’s meaningfully cheaper than the Litter-Robot — and comes with most of the same features.
- Compact footprint: It’s smaller than the LR4, which matters if you’re tight on bathroom real estate.
- Ionic purifier: The built-in air ionizer actually works. It neutralizes odors between cycles without relying solely on carbon filters.
- App features: The Petkit app gives you usage logs, health tracking, and remote controls. It’s decent, though not as polished as the Whisker app.
- Quiet operation: Noticeably quiet during the rotation cycle — a plus if your cat is skittish or the box is near a bedroom.
Where Leo’s Loo Too Falls Short
- Shorter warranty: Only 1 year. If something breaks at month 14, you’re on your own.
- App reliability: The Petkit app has occasional connectivity hiccups. Not a dealbreaker, but it’s less polished than the competition.
- Brand longevity: Petkit doesn’t have the same established track record as Whisker (LR4’s maker). If you want confidence in long-term support, that matters.
- Clumping litter required: Like most self-cleaning boxes, it only works well with clumping litter. Non-negotiable.
Litter-Robot 4: The Honest Take
The Litter-Robot 4 is the fourth generation of what’s arguably the most trusted automatic litter box brand in the world. Whisker has been refining this product since 2000. The LR4 launched in 2022 and added laser-based cat detection, a redesigned OdorTrap system, and a much-improved app.
What Litter-Robot 4 Does Well
- Build quality: It feels built to last. The plastics are thick, the mechanisms are robust, and the overall fit and finish is excellent.
- 3-year warranty: This is a big deal. Three years of coverage on a ~$700 appliance is genuinely reassuring.
- OdorTrap system: The combination of carbon filter and sealed waste drawer does a better job containing odors than most competitors — including the Leo’s Loo Too in side-by-side use.
- Whisker app: Polished, reliable, and packed with features — cat weight tracking, health insights, cycle history, and smart notifications.
- Proven reliability: Thousands of reviews over years of use. This thing works, and Whisker’s customer support is solid when it doesn’t.
Where Litter-Robot 4 Falls Short
- Price: $699 is a lot. There’s no getting around it.
- Bulkier size: The LR4 is bigger than the Leo’s Loo Too. If space is tight, this is a real constraint.
- Consumable costs: Replacement carbon filters, waste drawer liners — the ongoing costs add up over time.
- Overkill for some: If you have one small cat and a tight budget, this might be more automatic litter box than you actually need.
Head-to-Head: The Details That Actually Matter
Odor Control
Winner: Litter-Robot 4
The LR4’s OdorTrap system — a combination of a tight-sealing waste drawer and carbon filter — outperforms the Leo’s Loo Too’s ionic purifier in real-world use. The LLT’s ionizer is good, but if you’re in a small apartment or have multiple cats, the extra odor containment of the LR4 is noticeable.
Noise Level
Winner: Leo’s Loo Too (slight edge)
Both are quiet by automatic litter box standards, but the LLT runs a little more silently during the globe rotation. If you have an anxious cat or the box is in a bedroom, the LLT wins here by a small margin.
App Experience
Winner: Litter-Robot 4
The Whisker app is more polished, more stable, and more useful than the Petkit app. Health trend tracking, litter level monitoring, and notifications all work more consistently. The Petkit app gets the job done, but it’s been known to drop connections and feel less intuitive.
Ease of Cleaning
Winner: Tie
Both use pull-out waste drawers lined with bags. Both require periodic deep cleans of the globe. Neither is dramatically easier than the other — you’re looking at a 5-10 minute chore every few weeks for either unit.
Reliability
Winner: Litter-Robot 4
The LR4 has a longer track record and a stronger warranty. That said, Leo’s Loo Too has generally positive reviews for day-to-day reliability — it’s just that when something goes wrong, you have less coverage and a less-established support ecosystem behind you.
Price & Value Breakdown
Let’s be direct about this:
- Leo’s Loo Too: ~$549 upfront, 1-year warranty. If it lasts 3 years without issue, you’ve saved $150 over the LR4.
- Litter-Robot 4: ~$699 upfront, 3-year warranty. You’re paying a $150 premium for better odor control, a better app, and significantly more warranty coverage.
If you factor in the cost of an extended warranty (or the cost of replacing a unit that dies just outside the 1-year window), the Litter-Robot 4 starts to look more competitive on value.
That said, $150 is real money. If you’re on a budget or have a single cat who’s easy on equipment, the Leo’s Loo Too is a legitimate choice — not a compromise.

Frequently Asked Questions
Is Leo’s Loo Too worth buying over Litter-Robot 4?
For many cat owners, yes. If the $150 price difference matters to you and you have one or two cats, the Leo’s Loo Too delivers 80-90% of the Litter-Robot 4’s functionality at a lower price. Just go in knowing you’re getting a shorter warranty and a less-established brand.
Which has better odor control — Leo’s Loo Too or Litter-Robot 4?
The Litter-Robot 4 has the edge here. Its OdorTrap system (carbon filter + sealed drawer) contains smells more effectively than the Leo’s Loo Too’s ionic purifier, especially with multiple cats or in smaller spaces.
Can both handle multiple cats?
Yes — both are rated for up to 3 cats and up to 25 lbs per cat. If you have 3 cats, you might want two units regardless of which brand you go with, since one box for 3 cats can get overwhelmed even with automatic cleaning.
Is the Litter-Robot 4 really worth the extra money?
If better odor control, a longer warranty, and a more polished app are important to you — yes. If you’re budget-conscious and those differences sound minor, the Leo’s Loo Too is a solid machine and you won’t regret buying it.
