13800 Pa variable suction

Anti-slip tank treads hold firm, and 3800 Pa suction adjusts to how dirty the glass is. Microfibre cloths reach 99.73% of the way to the edges.

2Ultrasonic mist, two water tanks

Ultrasonics turn water into an even fine mist that loosens grime without streaks. Two 25 ml tanks mean fewer refills, and SLAM reads frames and obstacles to plan the path.

3App, remote, UPS and safety rope

Run it from the 10-language app or the 2.4G remote with 10 m range; one touch starts it and it returns to the start point when done. A UPS gives 30 minutes in a power cut, and a 5 m safety rope guards against falls.
