Petkit Purbot Ultra

The Petkit Purbot Ultra and the Petkit Pura Max 2 are both advanced, self-cleaning litter boxes designed to use sand litter. A notable distinction between the two models lies in their classification and potential feature set, as the Purbot Ultra is also categorized as a general 'Litter Box Accessory' alongside being a primary 'Cat Litter Box'. Functionally, both share the core convenience of automated cleaning and compatibility with sand-type litter. While the Pura Max 2 focuses clearly on being a primary litter box system, the Ultra's broader categorization suggests it might incorporate unique accessory features or operational modes. For consumers prioritizing the latest iteration or specific enhancements beyond the established Pura Max 2, investigating the Ultra's specific upgrades is recommended.
