Feature: 1. Atomization Dust Removal: This electric window cleaner adopts ultrasonic atomization automatic water spray device, the sprayed water mist can better wrap and condense with the dust particles on the glass, forming a peeling state at the wiping surfaces, and easily wiping away dust 2. AI Intelligent Path: With 3 smart path planning modes, this window cleaner follows Z shape cleaning route to maximize efficiency and minimize leakage points, suitable for various types of glass, including frameless window. After cleaning, the robot will automatically return to the starting point 3. 30ml Water Tank: This automatic window cleaner provides 30ml water tank, large capacity design enough to wipe 10‑20 square meters of glass. It sprays water every 10 seconds to evenly cover the area; Can be filled with no corrosivity cleaning products such as clear water and glass water 4. Accurate Control: Set up one set of water spray points, 1.4ml of water can wipe 1m² of glass, fine control for spray pressure and output water volume, achieve ideal humidity in the wiping area, and have adsorption, dust locking, decontamination, and water saving functions, efficient and accurate 5. Scientific Design: This window cleaning robot supports alternate spraying and wiping, accurately covering the entire wiping trajectory. It scientifically presets the nozzle angle, spraying frequency, and spraying range, and cleans wet areas with a high proportion, resulting in a high wiping rate 6. High Efficiency: The vacuum motor, combined with ultra fine fiber cleaning cloth, easily cleans the glass, with 72W power and 3000Pa suction. The circular cleaning wheel imitates gestures and has a rubbing movement of up to 70 revolutions per minute, making glass cleaning easier and more efficient Specification: Item Type: Automatic Window Cleaner Material: ABS, Fiber Cloth Rated Power: 72W Suction: 3000Pa UPS Power off Guard Time: 20min Remote Control Power Supply: 2 x 1.5V AAA Battery, Capacity: 1300mAh (included) Main Unit Battery: 1 x 3.7V Polymer Lithium Battery 650mAh (built in) Noise: 65dB Border Detection: Automatic Fall Prevention Control: UPS Uninterruptible Power Supply System, Security Rope Water Tank Capacity: 30ml Spray Method: Automatic or Manual Automatic Spray Technology: Ultrasonic Spray Cleaning Mode: Rotation Adsorption Method: Vacuum, Double Rings Security Rope: Approx. 4m / 13.1ft Movement Mode: N+Z, N, Z.
