Our take
Mamibot iGLASSBOT W100
A small-pane maintenance robot rather than a heavy-duty window cleaner. It can make awkward exterior glass safer to reach, but owner feedback points to noise, occasional spray faults, cable tangling and unreliable navigation on some windows.
Positive owners value being able to clean high or awkward outside glass without climbing and say it can cope with routine road dust and grime.
Reported problems include a failed spray nozzle, vacuum-cleaner-like noise, confused navigation, stopping mid-pane and winding the power cable around itself.
Glass-cleaning jobs that benefit from compact window cleaner.

What owners and reviewers say
W100 owners value its help on difficult outside glass, while reporting pad changes, missed corners and some spray faults. Its own documentation also limits frameless-glass use.
Useful access, with repeat cleaning
On DNS’s exact W100 review page, purchasers described cleaning road dust, construction dirt and outside balcony glass that was awkward to reach. Several needed frequent cloth changes or a second run. One owner accepted unfinished corners and wiped the accessible lower edge manually. These comments support reduced physical effort, not a universally spotless finish.
[2]Noise, pads and reported faults
Two detailed purchasers compared the sound with a vacuum cleaner. One wanted more pads because heavily dirty panes required a fresh set each time. Separate reports described a failed sprayer, including a later fault after an initially positive review, and another buyer reported a pad-drive problem. These individual faults do not establish a defect rate, but they make support and consumable availability relevant.
[2]Frameless glass is not recommended
Although the W100 has pressure-based edge detection, Mamibot explicitly does not recommend frameless-glass cleaning for this model. The presence of an edge sensor should therefore not be read as unrestricted frameless compatibility. The company also excludes cleaning the underside of horizontal surfaces.
