Source verdict

The reviewer concludes that the new Litter-Robot 5 and EVO models are "much better overall machines" and offer improvements over the Litter-Robot 4. However, they are not considered a "huge generational leap" like the transition from Litter-Robot 3 to 4. Despite some noted downgrades, the Pro model is highlighted as the flagship.

About this source

This review provides an in-depth comparison of Whisker's three new Litter-Robot models: the Litter-Robot 5, 5 Pro, and EVO. The reviewer highlights the differences between these models and the Litter-Robot 4, focusing on design, features, and functionality. It also discusses the value proposition of the new machines.

Review notes

The new Litter-Robot 5, 5 Pro, and EVO models represent a significant improvement over the Litter-Robot 4, offering enhanced features and design without being a revolutionary leap. The Litter-Robot 5 models boast a more premium build and an extra inch of interior height, along with a useful color LCD display providing detailed stats. However, the smaller globe liner design in the 5/Pro models can hinder clump dislodgement, and the lack of a changeable litter filter restricts the use of popular tofu litter. If you prioritize advanced health monitoring and the latest tech, the Litter-Robot 5 Pro is the flagship choice. For those with budget or space constraints, the EVO offers a more affordable entry, though it sacrifices some advanced sensors and control panel functionality.

  • Black units show dirt easily; reviewer recommends white models

Structured claims

The Litter-Robot EVO is marketed as the most affordable new Litter-Robot at $599 and is the smallest in size, though its interior remains reasonably large.

specification_claimmoderate

The Litter-Robot EVO relies solely on weight sensors for cat detection, lacks entry sensors, and cannot display litter or waste levels. Crucially, key settings like cycle delay cannot be adjusted via the physical control panel, a significant downgrade from previous models, making it entirely app-dependent.

reviewer_claimstrong

Unlike other Litter-Robot models, the EVO does not include an interior night light. The design also makes it tricky to mount a personal camera due to the rotating front and lack of an onboard USB power socket.

reviewer_claimmoderate

The Litter-Robot 5 Pro is distinguished by its two integrated cameras, one facing forward and another viewing the litter bed, designed for advanced health monitoring and tracking.

specification_claimmoderate

The Litter-Robot 5 maintains the same footprint and entrance size as the LR4 but is slightly taller with a one-inch increase in interior height. It features a more premium and sturdy build quality, especially the bonnet, and replaces the LR4's status lights with a clear color LCD display showing status, usage data, and litter/waste levels.

reviewer_claimstrong

The Litter-Robot 5's new smaller liner design with a rim is a step backward, as it may cause stuck clumps to not dislodge during cycles, unlike the previous larger liner. The machine also still lacks the ability to change litter filters, rendering it incompatible with popular large granular litters like tofu, which get sifted into the waste bin.

reviewer_claimstrong

The Litter-Robot 5 operates as quietly as the LR4 and features a redesigned interior front for better urine diversion into the waste bin. While the waste port and bin are slightly larger, the reviewer noted a minor issue with waste buildup at the rear, though deemed it not a major concern with regular checks. The odor seal is highly effective.

reviewer_claimstrong

Both the Litter-Robot 5 and EVO (with EVO lacking entry sensors) incorporate multiple strong safety mechanisms, including cycle stops for cat entry, pinch bars for obstructions, and motor resistance detection. However, the reviewer emphasizes that these machines are not suitable for small kittens due to minimum size and weight requirements, advising manual cycling for young cats.
