Litter-Robot manufactures three automatic litter box models that serve different budgets and needs for cat owners managing multiple cats.

The Litter-Robot 4 costs around $699 and delivers core automatic functions. It self-cleans after every use and connects to the Whisker app, which lets owners monitor litter box activity and cat health remotely. The machine handles multi-cat households effectively.

The Litter-Robot 5, priced near $799, adds meaningful upgrades. It introduces WasteID odor-detection technology that identifies waste and triggers cleaning cycles more intelligently. The drawer capacity increases, and an LCD screen replaces basic indicator lights. The LR5 also functions on carpet without requiring additional accessories, addressing a common pain point for cat owners with non-hardwood flooring.

The Litter-Robot 5 Pro reaches $999 and represents the premium option. It builds on the LR5's features with enhanced capabilities for serious cat enthusiasts or those with persistent litter box concerns.

All three models share fundamental strengths: automatic cleaning after use, Whisker app integration, and multi-cat compatibility. The choice depends on budget and specific household needs.

Cat owners with single cats or basic requirements may find the LR4 sufficient. The $100 jump to the LR5 brings practical improvements like better odor control and carpet compatibility that justify the expense for most households. The LR5 Pro suits owners who want the absolute best performance and don't mind premium pricing.

Automatic litter boxes require regular maintenance regardless of model. Owners should budget for litter supplies, occasional part replacement, and app subscriptions. The Whisker app provides valuable data about cat elimination patterns, which can alert owners to potential urinary tract infections or other health issues requiring veterinary attention.
