Petkit PuraMax 2 vs Smarty Pear Leo's Loo Too

The PuraMax 2 logs usage in an app — fine for curiosity, useless in a health emergency. The Leo's Loo Too sends a push notification every single time your cat uses the box. For a cat with a history of urinary blockages, missing a day of bathroom visits can be life-threatening. That real-time alert isn't a feature — it's a medical tool.

Every other automatic litter box — including the Leo's Loo Too — makes you pour litter through a small entry hole, which is awkward enough that Smarty Pear literally recommends using a jug instead of a box. The PuraMax 2 rotates so the opening faces straight up. It takes 10 seconds. This sounds minor until you've done it 50 times.

The Leo's Loo Too uses UV light to sanitize the barrel, which sounds impressive but doesn't address the smell between cycles. The PuraMax 2 attacks odor three ways: a sealed waste bin, a dedicated odor-eliminator attachment, and a citrusy deodorizing spray that fires automatically. Reviewers consistently say the PuraMax 2 smells actively good — not just tolerable.

The Leo's Loo Too costs $700. The PuraMax 2 runs $370–$500. That's a $200–$330 difference for a device that scoops cat waste. Unless you're actively using the health monitoring features, you're paying a significant premium for a quieter motor and a UV light. For most owners, that money is better spent on vet visits or premium litter.
