Which is better for two cats?

The Litter-Robot EVO. It is rated for up to 2 cats weighing 3–19 lbs. The PetSnowy SNOW+ listing gives a minimum cat weight and age but no multi-cat rating.

Is the PetSnowy SNOW+ worth $225 more?

Only if sealed bag packing, the TiO2 odor system and the tracking walkway matter to you. The EVO covers the core self-cleaning job for $303.99 at eBay as of November 5, 2026.

Which controls odors better?

Both work. The SNOW+ claims a 90.5% ammonia removal rate with TiO2, though some buyers find its deodorizer scent strong. The EVO uses a sealed drawer with multi-layer carbon filtration.

Which takes up less space?

The EVO. Its footprint is 52.3 × 61.7 cm. The SNOW+ is 74.9 × 50.8 cm and weighs 20.41 kg.

How often do you empty each?

The EVO goes up to 7 days between drawer empties in a one-cat home, less with two. The SNOW+ has a 10 L bin with auto-sealing bags, but buyers report changing bags often because of smell.

Buyers of both describe quiet cycles. The EVO uses QuietSift sifting; the SNOW+ is praised for quiet operation.
