Litter-Robot makes three automatic litter box models that appeal to different budgets and cat households. The Litter-Robot 4 costs around $699, the Litter-Robot 5 runs $799, and the Litter-Robot 5 Pro reaches $999.
All three machines share core features. Each automatically cleans after every use, connects to the Whisker app for remote monitoring, and handles multi-cat homes effectively. This means any model lets you track your cat's bathroom habits and receive alerts on your phone.
The Litter-Robot 5 introduces meaningful upgrades over the LR4. It features WasteID odor-detection technology that identifies waste more accurately before disposal. The drawer capacity increases, reducing how often you empty it. An LCD screen replaces the basic display, giving you better visibility into the machine's status. The LR5 also operates on carpet without issues, something the LR4 struggled with.
The Litter-Robot 5 Pro represents the premium option. It builds on the LR5 with additional features designed for households seeking maximum convenience and control. The $200 price jump targets owners willing to pay more for enhanced functionality.
For most cat owners, the choice comes down to how much you value the LR5's odor detection and larger capacity. If your cats are in a carpeted area, the LR5 becomes the practical minimum since the LR4 wasn't designed for carpet use. The LR4 still works well for tile or hard flooring and handles basic multi-cat situations.
The LR5 Pro sits in a gray zone. Pet owners should identify which specific features matter to them before paying the premium. If WasteID odor tech and increased drawer size solve your current litter box problems, the standard LR5 delivers excellent value.
