The Popur S7 automatic litter tray is one of the more unusual smart pet products I’ve reviewed. After over five months of daily use, it’s clear this device has a lot going for it—but also some notable shortcomings. This is not a straightforward recommendation.
At a high level, I like the Popur S7. It works well, my cats use it happily, and it solves many of the problems associated with traditional litter trays. However, it still feels like a product that hasn’t fully matured, particularly when it comes to software and feature completeness.
Price and Ongoing Costs
The Popur S7 typically retails around £560, although it is frequently discounted closer to £440. This places it firmly in the premium category of automatic litter trays.
There are also optional extras to consider:
- Additional sifters for different litter types
- Replacement litter pads designed to reduce sticking
- Waste bin bags
- A front guard rail for cats that kick litter
While these accessories aren’t essential, they can improve the overall experience depending on your setup.
Design and Build Quality
The Popur S7 has a modern, functional design available in white or grey. It’s not a small unit, but it strikes a balance between footprint and usability.
The litter area is spacious enough for average-sized cats, and the overall construction feels solid. Compared to similar devices, the build quality is impressive, with a mix of durable plastics and a metal waste bin.
One standout feature is the modular design. Many components—including motors and internal parts—are replaceable, which is excellent for long-term maintenance and repairability.
Ease of Cleaning
Cleaning the Popur S7 is one of its strongest areas.
The removable litter pad makes a big difference. It can be unclipped and lifted out easily, even with litter still inside if you’re careful. This simplifies both routine maintenance and full cleaning.
For day-to-day upkeep:
- The interior stays relatively clean
- The sifter can be removed for quick cleaning
- Dust can be wiped or vacuumed easily
The waste bin does an excellent job of containing odours, and the bag system helps keep things hygienic. In practice, this is one of the least smelly litter solutions I’ve used.
The only real limitation is the lack of a dedicated “empty” function. Fully clearing the litter requires manually removing and tipping the tray, which isn’t as convenient as it could be.
Setup and App Experience
Setting up the Popur S7 is straightforward from a hardware perspective. Assembly is simple, and connecting to WiFi is relatively painless.
However, the software experience has been inconsistent. At launch, the app was not ready, and even now some features are still missing.
Currently, the app includes:
- Cleaning cycle controls
- Bin status monitoring
- Customisable notifications
- Detailed usage logs
- Extensive configuration options
What’s still missing includes cat weight tracking and deeper pet analytics. These were expected features and their absence reinforces the feeling that the product is still evolving.
Performance and Daily Use
In everyday use, the Popur S7 performs well. The cleaning cycle is effective, and the system handles waste reliably.
The process involves:
- A delay after use
- Lifting the main body
- Sifting clean litter from waste
- Depositing waste into the bin
There are a few quirks:
- Some litter may stick to the sides or sifter
- The bin can fill unevenly
- It’s not as quiet as advertised
Despite this, it still represents a major improvement over manual litter trays.
Noise Levels
This is not a silent device. While the motor itself isn’t overly loud, the mechanical movement—especially the accordion mechanism—adds noticeable noise.
If placed near a bedroom, you may want to schedule cleaning cycles to avoid disturbances overnight.
Safety Features
Safety has clearly been a focus, particularly given concerns with earlier models.
With the correct settings enabled, the Popur S7 includes:
- Motion detection to pause operation
- Sentinel mode to prevent operation when a cat is present
- Firmware updates improving behaviour over time
In real-world use, it feels safe and reliable when configured properly.
Customer Support and Reliability
Customer support has been responsive in my experience, with quick replies and proactive solutions.
The modular design also helps mitigate long-term concerns, as replacement parts are available for many components.
Key Downsides
- Software and features were not ready at launch
- Some promised features are still missing
- Noise levels are higher than expected
- Bin detection can be inconsistent
- Feels like an evolving product rather than a finished one
Final Verdict
The Popur S7 automatic litter tray is a capable and well-designed product that delivers real benefits in terms of cleanliness, odour control, and convenience.
However, it’s difficult to ignore the unfinished aspects—particularly the app and missing features. At this price point, that matters.
If you’re comfortable with a product that is still improving through updates, it’s a strong option. If you want something polished and complete out of the box, it may be worth waiting.
