Devoko or Gimars: which self-cleaning litter box is the smarter buy?

Overview

These are both app-controlled self-cleaning litter boxes aimed at multi-cat homes, but they take slightly different approaches. The Devoko is the larger, pricier option at £199.99 with a 90L capacity, 6 safety sensors and a more enclosed “robot” style design. The Gimars costs £169.99, has a higher user rating at 4.5/5 from 123 reviews, and uses an open-top design that may be easier for some cats to accept. On paper, Devoko looks like the more feature-heavy machine, while Gimars looks like the more approachable and better-valued one.

Design and cat comfort

Winner: Gimars

The open-top design is a major practical advantage for many households. Cats that dislike enclosed spaces, older cats, or larger cats often prefer a tray they can step into without feeling trapped, and the Gimars is explicitly marketed for multiple cats and senior cats. That design can also make it easier for owners to monitor litter condition and cat behaviour at a glance. The Devoko’s enclosed, anti-pinch smart robot style may help contain litter scatter better, but it is more likely to be rejected by cautious cats who want easy visibility and escape routes.

Safety and reliability

Winner: Devoko

Devoko has the stronger safety spec on paper, with 6 safety sensors and anti-pinch positioning. That extra sensor count suggests a more cautious approach to cycle interruption if a cat approaches or enters during cleaning, which matters in a home with active kittens or multiple cats sharing one box. Gimars also includes safety sensors, but the listing is less specific, so Devoko has the edge for buyers who want the most reassurance around automatic cycling. For pet welfare, that matters more than flashy app features.

Capacity and multi-cat suitability

Winner: Devoko

The 90L capacity is a meaningful advantage if you have several cats or a bigger breed. A larger waste and litter chamber can reduce how often you need to empty or top up the unit, which is especially useful in busy households. Gimars is also designed for multiple cats, but without a stated capacity in the listing, it is harder to judge whether it can match Devoko for longer unattended use. If your main concern is keeping up with high usage, Devoko is the safer bet.

App control and smart features

Winner: Tie

Both products offer app control, which should make it easier to monitor cleaning cycles and maintenance from your phone. However, neither listing provides enough detail on app quality, WiFi reliability, alert speed, or how well the software handles multiple users. In real use, app quality can matter as much as the hardware, but based on the information provided, there is no clear winner. If you value smart-home convenience, both are in the same broad category, though neither appears to be a premium app-first product.

Odour control and cleaning performance

Winner: Gimars

Gimars is explicitly marketed with low odour, and the open-top design may also make it easier to keep the litter area visually clean and well ventilated. That said, odour control in self-cleaning boxes depends heavily on how quickly waste is removed and how well the waste drawer seals, and the Gimars listing gives a more reassuring signal here than Devoko’s. Devoko may still perform well, but the listing focuses more on safety and capacity than odour management. For homes where smell is a top concern, Gimars has the clearer advantage.

Ease of cleaning and everyday maintenance

Winner: Gimars

Gimars includes trash bags and a litter mat, which are small but useful extras that reduce setup hassle and help keep the surrounding floor cleaner. The open-top format also tends to be easier to wipe down and inspect than a more enclosed robot-style unit. Devoko is described as “Easy Clean,” but the listing does not include accessories, so the ownership experience may be slightly more hands-on. If you want the least fiddly day-to-day routine, Gimars looks better thought through.

Price and value for money

Winner: Gimars

At £169.99, Gimars is £30 cheaper and also has the better rating, 4.5/5 versus Devoko’s 4.3/5. That combination makes it the stronger value choice for most buyers, especially when you factor in the included trash bags and litter mat. Devoko’s higher capacity and 6 sensors justify some of the extra cost, but not enough to make it the default recommendation for everyone. If you want the best balance of confidence and cost, Gimars wins value.

Overall user experience

Winner: Gimars

For most homes, Gimars looks like the more user-friendly option because it is likely to be easier for cats to accept, easier to maintain, and cheaper to buy. The higher review score suggests more owners are happy with the real-world experience, which matters a lot for a product that your cat must actually use every day. Devoko is the more technically ambitious unit, and its larger capacity plus 6 safety sensors make it attractive for heavier use. But unless you specifically need that extra capacity and more enclosed design, Gimars is the more balanced buy.

Overall summary: Devoko is the better pick if you want maximum capacity and the most specific safety-sensor setup. Gimars is the better all-round purchase for most people because it is cheaper, better rated, easier for many cats to accept, and comes with useful accessories. If you want the definitive answer: buy Gimars unless you have a very busy multi-cat household that genuinely needs the larger 90L Devoko unit.
