PETKIT PURA MAX 2 or Devoko 90L: which smart litter tray is worth it?

Display

Neither product has a display in the usual sense, so the practical equivalent here is app quality and how clearly the system communicates status, alerts, and cleaning cycles. PETKIT has the stronger reputation here. Its xSecure system and mature app ecosystem are part of a more polished smart-home experience, which matters when you want reliable notifications about litter levels, cleaning cycles, or safety interruptions. Devoko offers app control too, but with less evidence of the same refinement. Winner: PETKIT PURA MAX 2, because a cleaner, more dependable app experience matters more than a flashy spec sheet in day-to-day use.

Performance

This is the most important category, and both products aim to do the same job: automatically sift waste and keep the tray usable between manual cleans. PETKIT PURA MAX 2 has 11 safety sensors, which is a major confidence boost in a device that moves around cats. That extra sensor coverage should translate into better interruption handling and a lower chance of a cat being caught out mid-cycle. Devoko lists 6 safety sensors, which is respectable and better than many budget models, but it is still a step behind PETKIT on safety redundancy. On capacity, Devoko claims 90L versus PETKIT’s 76L, so Devoko wins on raw internal size. That could matter in a multi-cat household or if you want fewer litter top-ups. However, performance is not just volume: it’s how well the machine protects cats, completes cycles, and stays consistent. Winner: PETKIT PURA MAX 2, because the extra safety sensors and more established platform outweigh Devoko’s larger nominal capacity.

Build quality and design

PETKIT is the more premium product by a wide margin. At £499.99, it is clearly positioned as a higher-end unit, and that usually reflects in the fit, finish, and long-term confidence around the mechanism. The PURA MAX 2 also includes odour control with N50, which is a meaningful welfare-and-home-living feature rather than a gimmick, especially in smaller UK homes where litter smell can quickly become a problem. Devoko’s design sounds practical and spacious, and the anti-pinch smart robot positioning is reassuring, but the brand is less established and the product appears more value-led than engineered-led. Winner: PETKIT PURA MAX 2, for stronger trust in build quality, design maturity, and odour management.

Battery life

Neither product is a battery-powered pet tracker or camera, so battery life is not a meaningful differentiator here. Both are mains-powered automatic litter trays, and what matters instead is reliability during repeated cleaning cycles and how well the unit handles connectivity and power interruptions. In that sense, PETKIT’s more mature smart-home approach gives it the edge in perceived operational reliability, even though there is no battery spec to compare. Winner: PETKIT PURA MAX 2, by default, because battery life is not a deciding factor and the overall system feels more dependable.

Price and value for money

This is where Devoko wins decisively. At £186.99, it is £313 cheaper than the PETKIT PURA MAX 2, which is a huge difference. For many owners, that money could cover a year’s worth of premium litter, vet visits, or a second tray for another room. Devoko also brings a large 90L capacity and app control, so on paper it offers a lot for the money. The catch is that value is not just about upfront cost; it’s about confidence, safety, longevity, and whether the tray becomes a trusted part of your home. PETKIT is expensive, but its 11 safety sensors, stronger brand reputation, and odour-control system make the premium easier to justify if you want the least stressful ownership experience. Winner: Devoko 90L for pure value, PETKIT PURA MAX 2 for value over the long term if reliability matters most.

Game library/features

There is no game library here, but in pet-tech terms the feature set is where PETKIT pulls ahead. The PURA MAX 2 offers app control, odour control with N50, and xSecure safety across 11 sensors, which is a more complete package for real-world cat ownership. Devoko counters with app control, 6 safety sensors, anti-pinch protection, and a large 90L format, which is attractive on paper. But PETKIT’s feature set feels more rounded and purpose-built rather than simply big and cheap. Winner: PETKIT PURA MAX 2, because its feature stack is more convincing and better aligned with long-term use.

Overall user experience

The best self-cleaning litter tray should reduce stress for both you and your cats. PETKIT PURA MAX 2 is the better choice if you want the more polished, safer, and more proven experience: better safety coverage, stronger odour control, and a brand that has built trust in this category. Devoko 90L is appealing because it is so much cheaper and still offers app control plus a very large capacity, but it feels more like a budget leap of faith. If your priority is peace of mind and fewer compromises, PETKIT is the better buy. If your priority is getting automatic cleaning for the lowest possible cost, Devoko is hard to ignore. Overall summary: PETKIT PURA MAX 2 wins as the definitive recommendation for most buyers, while Devoko is the smart budget alternative for owners willing to trade some reassurance for a much lower price.
