The design of the Litter-Robot 4 differs from the Litter-Robot 3 Connect in several ways. The Litter-Robot 4 has a sleeker and more minimalist appearance that complements most homes, while the Litter-Robot 3 Connect looks bulkier and resembles a spaceship. The Litter-Robot 4 is available in black or white, whereas the Litter-Robot 3 Connect comes in gray or beige. Despite both weighing 24 lbs, the Litter-Robot 4 is smaller with overall dimensions of 29.5″ x 22″ x 27″ (height x width x depth) compared to the Litter-Robot 3 Connect’s 29.5″ x 24.25″ x 27″. One of the most notable design differences is the entrance size and shape. The Litter-Robot 4 features a circular entrance that measures 15.75″ x 15.75″, while the Litter-Robot 3 Connect has an oval-shaped entrance that’s 15.5″ high by 10.25″ wide. If you have larger cats, it’s recommended that you choose the Litter-Robot 4 due to its wider entrance.
