Review on 🧼 Mamibot W120-T Window Cleaning Robot Vacuum, iGLASSBOT APP/Remote Control, Automatic Tools for Windows, Glass, Tiles, Bathroom Cleaning by Ashley Johnson

This is a bit more than good, but there is certainly room for improvement. I'm sure there will be something better in a few years. You still need to wipe some parts of the window. I would say if all you care about is perfection, it's not. If you don't mind getting the job done, it doesn't. On the other hand, if you prefer not to do the job and are happy with a good job, that's fine.
