Our take
Mamibot iGLASSBOT W120-DP
A reasonable mid-price alternative to Ecovacs for ordinary framed or frameless windows, but there is much less independent performance evidence and fewer published manufacturer specifications.
The four-nozzle spray system, straightforward safety setup and mid-range price make it attractive to buyers who want a non-Ecovacs option.
Performance has not been independently established, the published specification set is thin and it still needs mains power plus a safety rope.
Glass-cleaning jobs that benefit from dual-side path planning.
Buyers who need a robot that is available to buy immediately.
- Dual-side path planning
- Dry and wet cleaning modes
What the evidence shows
The W120-DP is designed to make spraying and handling easier, but independent cleaning results and long-term owner experience remain unclear in the checked sources.
What changes the routine
Mamibot describes a slim body, spraying on both sides and a low-water alert. The app and remote offer directional cleaning and combined passes. Those features can reduce manual wetting and let the user choose a route, but no checked test establishes that the advertised belt-cleaning feature removes all ongoing maintenance.
[1]Power and glass suitability
The built-in battery is specified as emergency support after a power interruption, not cordless cleaning power. Mamibot supports framed and frameless vertical windows but excludes horizontal ceiling glass. Its surface guidance is therefore more relevant than assuming that every smooth pane around the home is suitable.
[1]Unanswered ownership questions
The documentation does not establish how often the W120-DP leaves streaks, needs repeat passes or stops at window hardware. Replacement-pad availability, nozzle upkeep and service experience also need model-specific owner evidence before a confident long-term recommendation can be made.
