Our scores explained
Every model on the site is scored on the same criteria, using the same scale: its position among models with verified data for that specification. Last place earns 6.5, first place 9.6, and the rest are scored in proportion to their rank. Here is how this model's scores are calculated.
Two model counts: the rank and average include product pages on this site scored for the criterion; the calculation compares the model with all catalogue models whose specification is verified, with or without a product page. A score assigned at publication may remain without a verified specification, so the first count can sometimes be higher.
Equipment: 6.9/10
UBPet C20 scores 6.9/10 on this criterion. Across the 29 product pages on the site with a score for this criterion, the average is 8: below average, Rank 23 out of 29.
| Shared baseline: last place in the ranking | 6.5 |
|---|---|
| 2 features found out of 20 tracked: 1 perform worse, 26 perform better, 7 are tied (including this model), among the 34 catalogue models with this specification verified | +0.4 |
| Equipment score | 6.9/10 |
Calculation: (1 + 7 ÷ 2) ÷ 34 = 13.24% of the ranking; 6.5 + 13.24% × 3.1 = 6.9/10, rounded to one decimal place.
Recorded features: Cat monitoring (Multi-cat identification), Maintenance and removable parts (Detachable globe).
The retailer does not specify: Safety features, Waste management, Odour control system, Backup battery, Consumables require replacement. These features are not counted.
The retailer does not specify “Waste bin capacity”: this criterion earns no points and is excluded from the overall score.
The retailer does not specify “Unit weight”: this criterion earns no points and is excluded from the overall score.
Who is the C20 suitable for?
You are looking for equipment for several cats and want to remove the entire globe for washing. The C20 could join your shortlist if weight-based identification suits your cats. Before choosing, you still need to check the available space, safety conditions and litter compatibility.
The UBPet C20 is aimed at households that want to distinguish between their cats more effectively and remove the globe for washing. We analysed its documented specifications, with 2 key features to note: identification of multiple cats by weight and a fully removable globe. The available information remains insufficient to assess all its functions.
1How does the C20 distinguish between multiple cats by weight?
+
When several cats share the same equipment, the ability to distinguish between them is a useful comparison criterion. For the C20, the manufacturer describes identification based on weight differences between cats. This feature therefore deserves your attention if your cats have different weights. However, it does not establish reliable individual recognition in every situation.
The accuracy of this identification and the weight difference required remain unspecified. If your cats are similar in size, ask the manufacturer how the system tells them apart. This function alone does not establish the presence of medical monitoring, health alerts or a detailed history. Our analysis recognises weight-based identification as a documented feature without attributing any additional capabilities to it.
2The C20's fully removable globe can be washed directly
+
The manufacturer states that the entire globe can be removed for washing. This provides a concrete basis for comparing C20 maintenance: the removable part can be separated from the appliance during cleaning. This option deserves more attention than a general promise of simplicity because it specifies exactly which part can be removed and for what purpose.
However, it does not indicate how many steps are involved, how long removal takes or how often washing is recommended. These details remain unspecified. Before making your choice, consult the manual for the removal procedure, permitted cleaning products and drying instructions. The ability to wash the globe directly should not be interpreted as permission to wash the entire appliance or its electrical components.
3What should you compare between the C20, the Pura Max and the Litter-Robot 4?
+
The Petkit Pura Max and the Litter-Robot 4 are alternatives to consider in this category. To compare them with the C20, look for comparable measurements covering interior space, entry height, tray capacities and permitted weight limits. These criteria help you match your choice to your cat and the intended location, rather than to a list of functions.
No reliable numerical comparison between these models can be made here: C20 measurements and verified specifications for these competitors are unavailable. We therefore cannot identify which is the most spacious, the quietest or the best suited to large cats. Obtain the technical specifications for the exact versions you are considering before choosing between these alternatives. The absence of documented measurements does not demonstrate a weakness in the C20.
Our final verdict on UBPet C20
The C20 is worth considering for households with several cats of different weights and buyers who value removable parts for washing. These features provide concrete reasons to include it in your shortlist.
Worth noting
The main point to watch is weight-based identification when several cats are similar in size: its accuracy and the difference required remain unspecified. Safety conditions, litter compatibility and dimensions also need clarification before confirming that this model suits your pet.
Our verdict:
Our assessment is favourable towards the documented functions but remains limited to them. The C20 deserves comparison for its identification of multiple cats and removable globe; the criteria that remain unspecified prevent a sufficiently supported overall recommendation.

Founder of Self Cleaning Litter Box Picks
I analyse specifications, manuals and buyer reviews to explain the differences between automatic litter boxes. I pay particular attention to the safety of the mechanism, the space available to the cat and maintenance requirements. I distinguish documented information from testimonials and information that still needs to be verified.

Frequently asked questions
How does the C20 tell multiple cats apart?
The manufacturer describes identification based on weight differences. This information does not guarantee recognition of cats with similar weights.
Can the entire globe be removed for washing?
Yes, the manufacturer states that the entire globe can be removed for direct washing. Consult the manual for the removal procedure and cleaning instructions.
Does identifying multiple cats provide medical monitoring?
Distinguishing animals by weight is not sufficient for medical monitoring. On its own, it does not establish an ability to detect a health problem.
Does the removable globe mean the entire device can be washed?
The documented washing instructions apply to the removed globe. They should not be extended to the base or electrical components; follow the instructions in the manual for each part.
