Our take
Mamibot iGLASSBOT W120-P
A useful budget window robot for simple panes and hard-to-reach glass, but owner feedback is genuinely mixed. It can save effort on routine cleaning, yet streaks, wet-pad slipping, edge misses and isolated early failures mean we would buy it only from a seller with an easy return policy.
Positive users value access to awkward windows and say it can clean surprisingly dirty glass with little manual effort.
Negative reports mention streaking, slipping when pads become too wet, incomplete edge cleaning and occasional early malfunction.
Glass-cleaning jobs that benefit from square edge-cleaning design.

What the evidence shows
The W120-P offers useful control over spraying and cleaning direction on paper. Its return-to-start and obstacle-handling claims still need independent confirmation in real windows.
Control over moisture and passes
Mamibot documents automatic spraying, selectable spray intervals through the app and manual spray commands. The available horizontal, vertical and combined patterns make the cleaning process adjustable. That flexibility is relevant when a pane needs another pass, but it is not evidence of a streak-free result.
[1]Handling between windows
The manufacturer emphasizes the slim, lightweight square body and a return-to-start feature intended to simplify removal. These are useful design intentions for repeatedly transferring the robot. The checked documentation does not establish how well return positioning works around awkward handles or frame intersections.
[1]Maintenance evidence is thin
The W120-P carries a relatively small 50 ml tank, so liquid supply remains part of the routine. Actual refill frequency, cloth-washing workload and nozzle durability were not established by a model-specific owner report. Those practical unknowns should remain separate from the manufacturer’s navigation claims.
[1]Manufacturer-only evidence; no measured cleaning or reliability outcome is implied.
