Leo's Loo Too review: radar sensing, UV odor control and 30 dB manners
Research updated November 10, 2026 / Clean Litter Lab notes
Leo's Loo Too is what happens when an appliance designer gets hold of a litter drum: rounded, quiet, finished in colours, and controlled by voice if you want it to be. Under the styling sits a serious sensing choice - radar motion detection that watches the approach zone, so the cycle pauses for a cat that is merely nearby, backed by four weight sensors. At $599 it charges Litter-Robot money, which sets the question this review has to answer: what does the premium buy beyond looks?
Part of the answer is manners: a claimed 30 dB operation, UV odor control with bamboo carbon filters, and an app with no subscription fees, stated as a feature because rivals charge them.

Honest limitations
- The 1 to 20 lb cat range is the narrowest here - very large cats are excluded
- Smaller support footprint than Whisker or PETKIT in the US
- The 6 L drawer is compact, so multi-cat homes will empty it often

The 20 lb ceiling is the real spec
Everything about this drum is generous except its cat range: 1 to 20 lb per the listing, the narrowest in the catalog. A lean household of one or two cats will never notice. A Maine Coon household is excluded on page one, and no amount of radar elegance changes that. The 6 L drawer tells the same story - this is a machine tuned for small households in small spaces, and judged on that brief it is coherent.
Where the Leo's Loo Too scores well
- Radar detection watches the approach zone, not just the drum interior, so pauses trigger before a cat enters
- UV odor control plus bamboo carbon filters is a genuinely different odor stack from carbon-only rivals
- No subscription fees for the smart features, stated plainly on the listing
- At a claimed 30 dB it is pitched at light sleepers and studio flats
What owners report
Owners bought it for the looks and stayed for the quiet. Praise centers on near-silent night cycles and the app working without a paywall. Complaints mention the weight ceiling for big breeds and a smaller drawer than expected. Several owners note guests mistake it for a piece of furniture, which for this buyer is the point.

Questions owners actually ask
What does the radar actually do?
It detects motion in front of the unit, so the drum pauses when a cat approaches, not only after the cat is inside and registered by weight. It is an extra sensing layer most rivals do not offer.
Does UV odor control work?
The listing pairs UV with bamboo carbon filtration in a sealed 6 L drawer. Owners credit the seal and the cycling for odor performance; UV is best treated as a supporting claim rather than the mechanism.
Is there really no subscription?
The listing states essential smart features carry no monthly fees, with Alexa and Google Assistant control included. That was the position at our November 2026 check.
How quiet is 30 dB?
Roughly a whisper at a metre, per the manufacturer's figure. Owner reports describe night cycles as unobtrusive, which matches the claim's direction if not its precision.
What litter does it want?
Clumping clay is the recommendation on the listing.
Lab verdict
Design-conscious one or two cat homes in small spaces that want quiet cycles and no app subscription.
Skip it if: your cat is over 20 lb, or you want the deepest parts and support network - the Litter-Robot 4 is the safer long-term buy.
