Sensors & Hardware
Unlike most window robots, the W120-DP holds to glass via air-pressure adhesion (not vacuum suction), backed by pressure and photoelectric edge sensors, a gyroscope, and anti-fall detection. Mamibot's own user manual explicitly requires tying a safety rope to an indoor fixture before use — a manual requirement, not just a marketed accessory.
Insights
Mamibot markets this model simply as the W120-DP (also branded "iGLASSBOT W120-DP") across its own site, user manual, and all retail listings — no "-WB" or similar suffix appears in any official or retail source.
