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

The first attempt was to wash a mirror clean enough to see how it works. Filled the tanks, slightly moistened the rag. After washing, it left a little streaks, but for testing the norms. What was bad - he didn’t reach the top, he constantly slipped. From sprinklers, it sprays almost horizontally, with little force, it settled well on the mirror if half of what it sprayed. The second attempt was to wash the dirty glass outside. According to the instructions, they launched it first with a dry rag, it traveled a bit, then it stopped at the border of the window and froze. On pressing any buttons on the remote, it squeaked, but did nothing. It was very inconvenient to climb to take it off. Another try, same thing. The next attempt was decided to do with a damp cloth. We immediately realized the futility of sprinklers - there was about no wind (leaves on the trees moved a little), but this was enough so that nothing from what was splashing reached the glass. It turns out that sprinklers can only be used in conditions of absolute calm. At some point, without warning, he fell off and fell. It’s good that we didn’t trust him yet, and in addition to attaching the carbine to the battery, we also stood nearby and held the rope in our hands. I managed to catch it, it’s good that I didn’t fly to the windows of the neighbors from below. Next two attempts were on the inside of the window, began to complain about air leakage We decided to try it on another window, and here he was able to drive with a dry and damp cloth almost without incident. Only once I got stuck in a corner while trying to turn and I had to pull it out with a rope. The glass has become a little cleaner, but still dirty and streaked On this experiment, for the time being, decided to end. Another one of the crazy things - every time you turn it on, it starts to read aloud a long instruction manual After the trials, I can’t say that I lost faith in the fact that it is possible to make a normal window cleaning robot (there would be more suction power, and a stronger jet from the spray bottles), but this particular one is extremely useless garbage
