Review on HOBOT-298: Smart Window Cleaning Robot with Ultrasonic Water Spray, Smartphone Control, and Remote Operation by Som Sak ᠌

What dignity can we talk about if it does not fulfill its direct function at all. He cannot wash windows, he is able to move only through clean windows, on dirty ones he slips, stands still, moves in jerks, then generally starts to squeak and stops responding to any signals from the remote control. When you try to gently pull it on the safety cable, if it hangs somewhere, so that it returns (as it is written in the instructions), it simply falls off the glass. Before buying, I read a lot of reviews, opinions are different and inspired by the work of the vacuum cleaner robot (which I have been using for 2.5 years) I decided to buy it, I was very disappointed, just a useless thing for crazy money. Issued a refund. I wanted to add a video, a large volume is not added, if I can then I will cut it off, add it
