If you are tired of scooping cat litter every day, an automatic litter box can be a game changer. Two of the most talked-about options in 2026 are the Neakasa M1 Plus and the PetSafe ScoopFree SmartSpin. Both promise hands-free cleaning, but they take very different approaches. The Neakasa M1 features an open-top design that mimics a traditional box, while the PetSafe ScoopFree uses a sealed, spin-based system. This guide will walk you through their key differences, from safety sensors to odor control, so you can choose the right one for your feline friend.

Buying Guide
Safety and Detection Systems
When it comes to safety, the Neakasa M1 Plus uses a 6-array rotary infrared sensor that scans continuously to detect your cat’s position. This multi-angle system reduces false triggers and pauses operation the moment movement is detected. The PetSafe ScoopFree SmartSpin relies on a simpler weight-based sensor combined with a low entry height of 12 inches. While both are designed to protect curious cats, the Neakasa’s advanced sensor array offers more precise detection, especially for kittens or cats that approach quickly.

Odor Control and Leak Prevention
Odor control is a top priority in any self-cleaning litter box. The PetSafe ScoopFree SmartSpin features a sealed waste drawer with a deodorizer that the company claims delivers up to 4 times better odor control than traditional boxes. The Neakasa M1 Plus uses a built-in brush strip and an upgraded composite sealing ring to contain smells and reduce litter leakage. In our assessment, both perform well, but the PetSafe’s sealed drawer is more effective at trapping odors between cleanings, while the Neakasa’s open-top design allows for better airflow and less trapped moisture.
Capacity and Maintenance Frequency
How often you need to empty the waste bin directly affects your daily routine. The Neakasa M1 Plus offers an 11.2-liter waste bin and a 7.2-liter litter capacity, supporting up to 7 to 14 days of use for a single cat. The PetSafe ScoopFree SmartSpin also provides up to 2 weeks of hands-free cleaning, but its waste drawer is slightly smaller. For multi-cat households, the Neakasa’s larger bin gives you a few extra days between changes. Both units are easy to clean with smooth interiors, but the Neakasa’s dedicated spout for emptying litter adds convenience.
App Control and Health Monitoring
Smart features can help you keep tabs on your cat’s health. The PetSafe ScoopFree SmartSpin connects via the PetSafe Pet Companion app (2.4 GHz Wi-Fi) and provides real-time weight updates and usage logs. The Neakasa M1 Plus also offers app control through the Neakasa app, letting you monitor daily activity and adjust cleaning modes remotely. Both apps are useful, but the PetSafe’s weight tracking is more detailed, making it a better choice for owners who want to monitor weight changes closely.
Final Thoughts
After comparing these two leading automatic litter boxes, your choice comes down to your cat’s preferences and your priorities. If you prefer an open, natural-feeling space with advanced safety sensors and a larger waste capacity, the Neakasa M1 Plus Open-Top Self Cleaning Cat Litter is an excellent pick, especially for large breeds or cats that dislike enclosed boxes. On the other hand, if odor control and detailed health tracking are your main concerns, the PetSafe ScoopFree SmartSpin Self-Cleaning Litter offers a sealed system with app-based weight monitoring that can help you stay on top of your cat’s wellness. Both are reliable choices that will save you time and keep your home fresh.
