A Gold Vision window and glass cleaning robot with 7000 Pa of suction that holds it safely on surfaces. An array of 12 sensors (8 collision radars and 4 photoelectric sensors) detects edges, avoids obstacles and stops it getting stuck. The clamp fit dock attaches the cleaning pad with one click, and a UPS backup keeps it safe for 30 minutes if the power cuts out, with a 3.8 m safety rope. Control it from the app, the remote or a single button, with voice prompts. - Suction: 7000 Pa - Water tank: 120 ml with automatic spray - Noise level: quiet, about 70 dB - Control: smart app and remote control - Cord length: 4 m - Weight: about 1.60 kg - Battery: 500 mAh - Warranty: 1 year
