The suction is great; this robot really sticks to the glass. I tested it on a very dusty window, and while it did leave some streaks, the overall result was a massive improvement. I am confident that with a few more passes and by regularly rinsing the microfiber pad, this issue will be resolved. It's incredibly easy to use, and the noise level is not too bad. I especially like the remote control feature, which is perfect for cleaning specific areas, especially the edges.

This robot significantly reduced the work of cleaning my large outdoor mirrors. Its performance is directly related to the window size—the bigger the window, the better the result. Although it's slightly less effective on narrow windows compared to large ones, its cleaning performance is great for our home in the dusty desert region. Overall, I recommend it, but if you have extremely dirty corners, you might need to give them a little manual help.

This little window robot is truly impressive. Its suction power is amazing. I tested it on some of my dirtiest windows, and even then, it didn't lose its grip. The performance of this machine is truly remarkable, and it handles challenges with ease, which gives me great peace of mind when cleaning.

I was very hesitant to buy this, but now I'm so glad I did! I just used it to clean the windows for an 83-year-old lady whose windows hadn't been cleaned in at least 15 years. After just two passes, the windows were sparkling clean—it was unbelievable. Honestly, even my own manual cleaning couldn't achieve these results. This robot is incredibly effective and far exceeded my expectations
