At a glance

Expert's Rating

Pros

• Solar charging means that, in theory, you never need to plug in this robot
• Very effective cleaning (at least while its battery lasts)
• Lots of operating modes

Cons

• The effectiveness of solar charging varies with the weather, and it can take days even in optimal conditions
• Couldn’t clean my entire pool on a single charge, due to an undersized battery
• App is prone...
