Review on HOBOT-2S: The Ultimate Window Cleaning Robot with Dual Ultrasonic Water Spray and Smartphone/Remote Control by Athit Kemsatidanan ᠌

It requires constant presence and control: then the network will disappear, then the sink will stop after driving 30 cm, you have to restart it, then change the napkins, then something else. However, even a few starts are not enough for a normal washing result. I fiddled with it for more than an hour at one window, tried to wet the napkin in different ways to find the optimal dosage (of course, with branded liquid), but I didn’t find it, either it’s useless or too wet and the robot starts to move poorly, slip and slide, eventually spat and I washed it myself in 5 minutes. I thought that the gadget would save me time, it turned out that I have to spend much more with it. Just sticking to the window and going about your business while waiting for clean windows did not work. People in the comments write that if you wash the window first and then start the robot, then everything will be fine, but what is the point of the robot if you still have to wash the window with your hands🤔
