Automatic Electric Window Cleaner Robot Glass Vacuum Cleaning Tool APP Control New

 I purchased this product as kind of a spur of the moment thing. I was surprised that a window cleaning robot could be this cheap.I have now tried the robot in real life. First on a window on my balcony, so it could not fall down :) But I really did not have to worry. The Robot sticks very securely to the window. There is a safetry strap included that prevents the robot from falling down.Pros:+ very cheap+ did the job+ Clings to window in a reassuring fashionCons:- manual is in a hopeless English- Will not completely remove the need for manual cleaningThe English on the box and in the manual is rather hopeless and not very reassuring. And example from the box:"Powerful upgrade to thoroughly break through the limitation" Now, in all fairness this is a small problem, and does not mean the product is any worse. But I more or less had to figure out the product through trial and error because the manual was somewhat confusing. Fortunately it was fairly easy to figure out.Overall I am quite happy with my purchase. I am still amazed that a window cleaning robot can be purchased at such a low price. Just dont expect this little robot to do the work of an actual cleaning. It did a fairly good job of cleaning my windows, and it will certainly mean that I do not have to pay for a professional cleaner nearly as often. So in that light the robot will pay for itself many times over.
