HOBOT
The HOBOT-298 sprays water or detergent from a detachable 40 ml tank through an ultrasonic nozzle, which HOBOT says covers about 40 m² per fill. It uses a Nidec brushless motor for durability and lower noise.
RobotWise verdict
The cheapest credible way to try a window robot. Fine for occasional cleaning of a few large panes; step up to a station model if you have a lot of glass.
