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

Utter letdown. Due to flaws in the design, the test was failed on the day it was taken. This robot is inappropriate for you if your inner window bar is angled and relatively thin (less than one centimeter) because it cannot accommodate those kinds of bars. If it does not slip, which it almost always does regardless of how wet the rag is, it will run into the bar like a springboard, then it will separate from the glass and fall. Even during the dry cleaning process, the robot is unable to move smoothly across extremely filthy windows and instead skids along the surface. The sprayer is completely pointless because after every three sprays, a droplet forms on it, and after the subsequent spray, the droplet drips onto the ground below. Even with a light breeze blowing, practically all of the detergent is carried away when viewed from the outside. The first time I used it, I went through a state of shock and worry; after my initial fall out of the window, I stood up and hung onto the safety cord. When I caught it a second time, I realized that the model was dangerous, and on the outside of the window, its use was excluded for me even with insurance. At first, I thought it was an accident that it fell, but when I caught it again, I realized that (17th floor). As a result of the front bumper becoming dislodged, the button cannot be pressed, and the robot continues to slide around helplessly on the edge of the glass. That was not the first time that these items had been given to the store, so they took it in their stride and accepted it with understanding.
