It includes a self-cleaning base station, a mopping function, and enough high-end specs and charm that my colleague Jen Tuohy took notice. To say I’m impressed by the performance of the drone maker’s first and best robot vacuum is an understatement. This door folds down on the front of the base station for access to the cleaning cartridges and dust bag. DJI’s robot vacuum relies upon the same sensors used in its flagship drones. Paying €1,899 (about $2,250) for the top-of-the-line Romo P model buys you a very good, nearly autonomous DJI cleaning drone.
