Leo’s Loo Too Review: Is It Better Than Litter-Robot?

→ See also: Best Automatic Litter Box 2026: The Complete Guide (Tested & Ranked)

The Leo’s Loo Too is one of the most talked-about automatic litter boxes of 2025–2026 — and for good reason. At around $420, it undercuts the Litter-Robot 4 by nearly $300 while offering a smart app, per-cat usage tracking, and an active odor-control spray system. But is it actually better? We put it through its paces over eight weeks with two cats.

Bottom line: Leo’s Loo Too earns a 4.2 out of 5. It’s the best automatic litter box under $500 and a genuine alternative to the Litter-Robot 4 for most households.

Leo’s Loo Too: Key Specs at a Glance

Design & Build Quality

The Leo’s Loo Too has a globe-shaped drum that rotates to sift waste into the drawer below — the same fundamental design as the Litter-Robot. The finish is clean and modern (available in white and grey), and the build feels solid. It doesn’t feel like a $200 budget box; it feels like a premium product.

The 9-inch globe opening is wider than many competitors, which matters for larger or chunkier cats. Our Maine Coon mix (14 lbs) had zero hesitation stepping inside. The entry sits low to the ground as well, making it accessible for older cats or kittens who’ve grown enough to use it.

One minor design note: the waste drawer doesn’t have the same snap-seal feel as the Litter-Robot 4. It works fine, but you’ll want to empty it before it gets completely full to avoid any litter spillage during rotation.

Setup & App Experience

Setup took about 15 minutes. Plug it in, download the PETKIT app (Leo’s Loo Too is made by PETKIT), connect to your 2.4 GHz Wi-Fi, and you’re done. The app walks you through everything with clear visuals.

The PETKIT app is genuinely one of the best in the category. Here’s what it does:

• Per-cat usage tracking — add each cat’s profile with weight and it logs who used the box and when (using weight as identification)
• Health insights — tracks visit frequency, duration, and weight trends over time; flags anomalies that might indicate a health issue
• Scheduled auto-clean — set cleaning cycles at specific times or after each visit with a configurable delay
• Deodorizer control — manually trigger the odor spray or set it to fire automatically after each use
• Usage history — 30-day history visible at a glance
• Notifications — full waste drawer alerts, malfunction warnings

Compared to the Litter-Robot Connect app, the PETKIT app is more feature-rich at the same price point. The LR4’s app is clean and polished, but Leo’s Loo Too wins on data depth — the health-trend tracking alone is worth a lot if you’re monitoring a cat with urinary or digestive issues.

Odor Control: The Active Deodorizer System

This is where Leo’s Loo Too differentiates itself most clearly. Rather than relying solely on carbon filters or sealed waste drawers, it uses an active deodorizer spray cartridge that dispenses after each cleaning cycle.

In testing: it works. Our laundry room where the box lives stopped having the lingering litter smell we’d gotten used to. The spray is light — not perfumy or overwhelming — it just neutralizes odor effectively.

The downside: the deodorizer cartridge is a consumable that costs roughly $12–15 and lasts about 30 days with regular use (one cat). That’s $144–$180/year in ongoing costs on top of litter. It’s not a dealbreaker, but it’s worth factoring into the total cost of ownership.

You can extend cartridge life by reducing spray frequency in the app, or by skipping it entirely and relying on good clumping litter — but then you’re giving up the main differentiator.

Cleaning Performance

The globe rotates smoothly and quietly. At around 40–45 dB, it’s noticeably quieter than older self-cleaning boxes and comparable to the Litter-Robot 4. Our more skittish cat (a 7-year-old tabby) took about four days to fully accept it; we triggered manual cleans while she watched to help her get used to it.

Clumping efficiency is high — we saw less litter waste and fewer broken clumps than with our previous timed box. The sifting mechanism gets about 95% of clumps cleanly. On rare occasions a small clump will stick to the globe wall; a quick manual rotation clears it.

The waste drawer needs emptying every 7–10 days with one cat, or every 5–7 days with two. That’s slightly more frequent than the Litter-Robot 4 (whose drawer is larger), but still a significant upgrade over daily scooping.

Leo’s Loo Too vs Litter-Robot 4: Direct Comparison

This is the comparison most people are actually researching. Here’s the honest breakdown:

Our verdict: For 1–2 cats, the Leo’s Loo Too is the better value by a significant margin. The $280 price difference buys you a larger waste drawer and slightly more robust sensors in the LR4 — but for most households, the Leo’s Loo Too is more than enough. If you have 3+ cats or very large cats (20+ lbs), the LR4’s capacity advantage matters more.

Who Should Buy the Leo’s Loo Too?

Buy it if:

• You have 1–2 cats and want to step up from a basic timer box
• You want the best app experience in this price range
• You care about odor control and don’t mind the cartridge cost
• Your budget is under $500
• You want to monitor your cat’s health habits over time

Skip it if:

• You have 3+ cats — the smaller waste drawer will need daily or every-other-day emptying
• You have a very large cat (22+ lbs) — the 9-inch entry may feel snug
• You want zero ongoing consumable costs — the deodorizer adds up
• You’ve had a bad experience with PETKIT support — they can be slow to respond

Pros & Cons

Final Verdict: 4.2 / 5

The Leo’s Loo Too is the automatic litter box we’d recommend to most cat owners. It has the best app in its price range, genuinely effective odor control, and a build quality that punches above its price. The waste drawer is its only significant limitation — and for 1–2 cats, it’s a non-issue.

At $420, it’s $280 cheaper than the Litter-Robot 4 for performance that’s roughly 85–90% as good. That’s an excellent trade-off.
