Frequently Asked Questions
Common questions about this comparison
Which is better for multiple cats or larger cats?
The EYESUN is superior for multiple cats and larger breeds, supporting up to 27.5 lbs with its infrared and weight sensors. It also boasts a 13L waste drawer capacity, designed to handle more waste before needing emptying, unlike the UPFAS which is for medium cats.
What's the main difference in safety sensors?
EYESUN uses both infrared and weight sensors to detect pets, ensuring enhanced safety by pausing operation. The UPFAS relies solely on weight sensors for detecting cats and cleaning cycles. This dual-sensor system offers a more robust safety mechanism in the EYESUN model.
Is the price difference worth it?
The EYESUN at $299.99 justifies its higher cost with superior safety features, a larger maximum pet weight capacity of 27.5 lbs, and no assembly required. The UPFAS at $199.99 is more budget-friendly but requires 90 minutes for assembly and is only for medium cats.
Which has better waste capacity?
The EYESUN features a specific 13.0-liter waste drawer capacity, allowing it to hold waste for up to 15 days for multiple cats. The UPFAS product description does not specify its waste drawer capacity, suggesting EYESUN offers better transparency and potentially larger capacity.
Can I use both with an app?
Yes, both litter boxes are Wi-Fi enabled and offer app control and monitoring capabilities. You can remotely manage cleaning cycles and monitor your cat's usage without any additional app subscription costs for either product.
