"The U2 does what it sets out to do, and it does that well. While it is a basic navigating robot, the actual cleaning performance could embarrass some higher priced robots.
It’s important to understand that as a “smart random” robot, the U2 doesn’t utilise cameras or LiDAR to create a map. It is still somewhat methodical and will eventually cover an entire home but it does lack the total accuracy of its premium siblings that allow for smart mapping functions in the app. It is the only mopping robovac in it's price range and its performance is excellent, however it will need your help to avoid carpet.
The U2 is great value and will clean the right home impressively well. I’d personally be happy to use it in my own apartment, but I would only recommend it for other small homes with up to 3 bedrooms."
