Product Overview
The Mamibot iGLASSBOT W200 SkyBot is a cordless window and skylight cleaning robot — the rare one in this category that runs on its own battery instead of a tether. It draws on a detachable 3350mAh battery pack and manages up to 100 minutes of runtime, enough for roughly 30m² of glass per charge, cleaning at under 3 minutes per square metre. The body is 8cm thick, which the maker bills as the slimmest in its class, letting it get under low sills and onto tight roof-glazing. It delivers 2000–2600Pa of suction, adjusted automatically to how dirty the glass is.
Core Technologies & Safety
Four sensors handle frameless-edge detection, and the suction firmware raises pressure right at the glass boundary to stop the robot sliding off — the same risk profile as a corded unit, solved in software rather than by a cable. An AI path planner picks the cleaning route, and the robot returns to its start point on its own when a cycle ends. Noise stays under 65dB, quiet enough for indoor roof windows. Safety is a 1.5m tether to an indoor fixture plus a suction cup with a 2.5m extension for all-direction work. It is controlled by a 2.4G remote with a straight-line range up to 20m.
Key Advantages
This is the review to read if your skylights have no nearby power. Cordless operation is the W200’s entire reason to exist, and it earns that: 30m² per charge covers most domestic roof glazing, and the slim 8cm body reaches underframe gaps that fatter robots miss. The trade-offs are real. Suction tops out at 2600Pa, lower than the strongest corded machines, so it is a moderate-dirt tool rather than a heavy-dust one; and the 3350mAh pack means a large commercial roof would need spare batteries on rotation. Buy it for convenience and reach, not for throughput.
