Product Review · Robot Litter Boxes · #4 Ranked
Casa Leo Leo's Loo Too
Quiet enclosed drum, UV odor control · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 79
The quietest major robot litter box at around 30 dB, with an EPA-registered UV-C cycle, per-cat weight tracking and drums in colors nobody else offers, which is why Quality leads at 86. The 20 lb cat limit is low, the app trails Whisker and PetKit, it needs 1 inch of wall clearance, and Casa Leo (renamed from Smarty Pear in 2024) has a shorter reliability record. At $699.00 list with no subscription, Warranty is the softest at 55 with 1 year included and a 3-year extension sold separately.

Should you buy the Casa Leo Leo's Loo Too?
The Casa Leo Leo's Loo Too is the self-cleaning box for a light sleeper or a small apartment where the litter box lives near the bed. At about 30 dB it is the quietest cycle we rank, and it adds an EPA-registered UV-C light cycle for odor and bacteria control plus a nightlight. It costs $699.00, only $100 less than the Litter-Robot 4, and it insists on 100 percent clay clumping litter. It suits an owner who values silence and odor control over price and warranty.
Where it earns its score
- Quietest here. About 30 dB, quieter than the 35 dB PETKIT Purobot Max 3 and the 50 dB Neakasa M1.
- UV-C and carbon. A UV light cycle in the drum plus a carbon filter and heavy-duty bags keep the smell down in a small room.
- 16 sensors. Radar motion detection, four weight sensors and anti-pinch protection, with per-cat weight tracking in the app.
- Voice control. Works with Alexa and Google in addition to the Wi-Fi and Bluetooth app.
What to know first
- Clay clumping litter only. Not plant-based, not crystal, not pellet. That limits your litter choices more than most boxes here.
- Empties weekly. The 9.5 L drawer lasts about 7 to 9 days for one cat, shorter than the Neakasa M1's two weeks.
- Heavy and needs clearance. 37.4 pounds, about 24 by 22 by 27.6 inches, and it wants an inch of wall clearance behind it.
- Warranty is the weakest ViperScore factor. One year standard with a 3-year extension sold separately scores 55, which is why value lands at 74.
Our verdict
The Casa Leo Leo's Loo Too scores 79, Fair Buy, ranked #4 of 7 robot litter boxes. It is the right choice when noise and odor in a small space are the deciding factors. If neither is critical, the PETKIT Purobot Max 3 at 82 costs $200 less and empties less often.
