Litter-Robot 4 Automatic Self-Cleaning Litter Box vs Neakasa M1 Lite Plus Open-Top Self-Cleaning Cat Litter Box

Buy the Litter-Robot 4 if you have up to 4 cats, want the most proven self-cleaning design, and value a fully enclosed globe with app monitoring. Buy the Neakasa M1 Lite Plus if you have a very large cat (up to about 33 lbs), a skittish cat that dislikes enclosed spaces, or you want a lower-cost open-top box with a big waste bin. The Litter-Robot 4 is the higher-rated of the two (4.9 from 348 ratings vs 4.7 from 111), but no current prices were provided for either, so compare live store prices before deciding.
