W1 is a robotic window cleaner fitted with a vacuum cleaner. It uses the innovative dual-disk spin-scrubbing technology, which is a core patent, and allow you to do faster and more efficient window cleaning. The new WIN-Vacuum glass dedusting technology that uses the suction power of vacuum cleaner to clean off the dust attached on glass surface enables dry cleaning and the double-edge automatic ultrasonic atomization sprayer enables wet cleaning, allowing you to do an extraordinary cleaning job. The smart route planning function makes cleaning efficient and makes sure no spot is omitted, and the frame detection and air pressure detection modules allow the equipment to avoid obstructions and make cleaning work safer. W1 is innovative in that the vacuum cleaner used for floor cleaning is now used for window cleaning, which gives you perceptibly improved cleaning experience and makes your cleaning job simpler.
