Fanttik Aero X review: This robotic pool cleaner is an underwater monster

The Fanttik Aero X robotic pool cleaner runs fast and runs long: With six hours of running time and top-notch cleaning power, the device makes short work of underwater debris. In a world dominated by bulbous black-and-blue hardware, the Fanttik Aero X pool robot immediately caught my eye. It's not just that it's black and yellow, it's that the industrial design looks more like a lawn mower than any pool robot I've tested. It has much smaller front wheels than usual, and an exposed rubber drive belt that connects them to its motor. The forward-center brush cylinder is even reminiscent of the front of a lawn mower.
