Leo's Loo Too

Key Takeaways

  • Rating: ★★★★☆ (5,800 reviews)
  • Price: $449
  • Best for: Single-cat homes / Tech enthusiasts / Small spaces
  • Bottom line: UV sterilization built-in

"The Leo's Loo Too is the best choice for tech-loving cat owners who want smart home integration. At $449, it costs $250 less than the Litter-Robot 4 while still offering a full set of features. The UV-C sterilization light actually helps control bacteria in the waste drawer — this isn't just a marketing gimmick. Alexa and Google voice control work smoothly for starting cleaning cycles without touching the box. The trade-offs are a smaller waste drawer that needs emptying more often and an app that occasionally has connection hiccups. These issues keep it from beating the Litter-Robot 4 as our top pick. For a single-cat household where the smaller drawer isn't a problem, the Leo's Loo Too delivers excellent value. Tech enthusiasts who want voice control and UV sterilization will find it's exactly the right fit."

Frequently Asked Questions

Does UV sterilization in Leo's Loo Too really work?

UV-C light has been proven to reduce bacteria in controlled environments. In the Leo's Loo Too, it helps sanitize the waste drawer interior. However, it doesn't replace regular deep cleaning — think of it as an extra layer of hygiene, not a magic wand.

How do I set up Alexa/Google voice control?

Enable the Smarty Pear skill in your Alexa or Google Home app, link your Leo's Loo Too account, and you can trigger cleaning cycles, check the waste drawer level, and toggle UV sterilization by voice.

Is Leo's Loo Too quieter than Litter-Robot 4?

Yes — the Leo's Loo Too runs at under 30dB during cleaning, noticeably quieter than the Litter-Robot 4's ~40dB. If the box sits near a bedroom, this matters.
