Review on 🏢 Mamibot W120 Automatic Robotic Window Cleaner - Advanced Glass Cleaning Tool with Smart App/Remote Control for High-Rise Windows, Glass Tiles, and Bathroom Cleaning by Laura Peterson

I only have a W120. After reading the reviews I had higher expectations. At first it seemed like he had done a good job. It sucks well, works smoothly, goes from turn to turn. However, as the sun began to hit the window, I noticed streaks everywhere. The stripes become more visible from the outside after cleaning the windows. To minimize streaks, wash first with yellow (dry) clothes, then with gray (wet) clothes, and then with yellow clothes again. Even the window is clean, you need at least one wet and one dry, if it's outside I would do dry, wet X2 or 3, then dry. It seems like using clean clothes every time and drying at the end makes all the difference. However, it still cannot clean most of the corners due to its design. W120 wheels make cornering difficult. This made manual cleaning with a mop much faster and more complete. In addition, the remote control failed several times. I don't know if it's a faulty remote control. So I don't think I'll use this for accessible windows, but for hard-to-reach windows it can be very useful. I also like the price for a no-frills entry-level product. Overall, I have a feeling it may be another year or two before manufacturers come up with a design that works better and produces models at affordable prices for most consumers.
