If you’re ready to say goodbye to daily scooping, automatic litter boxes can make life with cats a lot easier. Two of the most talked-about options are the Smarty Pear Leo’s Loo Too and the PetSafe ScoopFree Crystal Pro. Each offers a self-cleaning design but takes a different approach to keeping things clean and odor-free. Here’s how they compare based on product details and verified user reviews.
Automatic Cleaning
The product description for the Leo’s Loo Too states that the unit automatically detects when a cat has finished using the litter box and sifts clumps from clean litter, depositing waste into a drawer below. It notes that most users only need to change the liner once a week.
According to the ScoopFree Crystal Pro product description, it also provides automatic self-cleaning through motion sensors and a rake system that moves waste into a covered compartment after each use.
Reviewers for both products confirm these automatic functions work effectively. Owners of the Leo’s Loo Too have noted that the system operates reliably and that their cats adjusted to it quickly. Reviewers of the ScoopFree Crystal Pro report that it works as advertised and that they appreciate not having to scoop manually.
Odor Control
The product description for the Leo’s Loo Too emphasizes odor control, mentioning a tightly sealed waste drawer, carbon filters, and EPA-certified materials. It also cites a 2024 survey indicating that all users agreed the product helps control odors.
The ScoopFree Crystal Pro relies on crystal litter to absorb liquid and dehydrate solid waste, with leak-proof trays that help maintain cleanliness.
User reviews support these claims. Leo’s Loo Too owners report that odors are minimal even in homes with multiple cats. Reviewers of the ScoopFree Crystal Pro have noted that while the system effectively eliminates urine odor, occasional poop smells can occur, especially when cats are transitioning diets.
Smart Features and Health Tracking
The Leo’s Loo Too includes app connectivity that tracks a cat’s weight, logs visits to the litter box, and allows users to start cleaning cycles remotely. The app also integrates with Alexa and Google for voice control.
The ScoopFree Crystal Pro includes an integrated health counter that tracks how often a cat uses the litter box. The product description does not indicate that it connects to an app or smart home devices.
According to reviews, Leo’s Loo Too owners enjoy the health tracking features and find the app helpful for monitoring their cats’ activity. ScoopFree reviewers appreciate the simple health counter but acknowledge it provides less detailed information than a connected app might.
Noise Level
The product description for the Leo’s Loo Too specifies that it operates at 30 decibels, describing it as whisper-quiet. The ScoopFree Crystal Pro description does not list a specific noise level.
Reviewers for the Leo’s Loo Too confirm that it runs quietly and does not disturb household routines. ScoopFree reviewers describe the product as fairly quiet but note that some cats may watch or react when the rake begins to move.
Maintenance and Support
The Leo’s Loo Too description indicates that most users change the liner once a week. It does not include information about long-term maintenance costs or replacement parts.
The ScoopFree Crystal Pro description explains that the litter box uses disposable trays that can be replaced every few weeks. The product description does not specify the cost of replacement trays.
Reviewers provide additional details about maintenance. Leo’s Loo Too owners mention that cleaning the drum monthly helps prevent buildup and that the company’s U.S.-based customer support is responsive. Some users experienced minor sensor issues that were resolved quickly under warranty.
ScoopFree reviewers frequently comment on the convenience of disposable trays but also note that replacing them regularly can become costly. Several users mentioned that purchasing reusable trays with crystal litter refills helps reduce ongoing expenses, though this information comes solely from user experiences, not from the official product description.
Final Thoughts
Both litter boxes succeed in automating one of the least enjoyable parts of cat ownership, but they appeal to different needs.
The Leo’s Loo Too is designed for cat owners who value advanced features and smart monitoring. The product description highlights its quiet operation, odor control, and app integration, while reviewers consistently praise its convenience, effective cleaning, and helpful customer support.
The ScoopFree Crystal Pro focuses on simplicity. Its product description emphasizes easy cleanup through crystal litter and disposable trays, and reviewers agree that it performs well for day-to-day use. However, users frequently mention that ongoing tray replacement costs can add up over time.
The product descriptions do not include long-term cost comparisons, so this information is based solely on user reviews.
In summary, the Leo’s Loo Too is ideal for those who want advanced automation and smart tracking, while the ScoopFree Crystal Pro suits those looking for an easy, reliable system with minimal setup.
