Review on HOBOT-388 Smart Robot Cleaner for Automatic Window Glass Cleaning with Ultrasonic Water Spray, Smartphone or Remote Control by Maejima Riko ᠌

A very handy thing. The kit comes with a relatively long safety cable and power cable. Important - the machine does not work without a power cable - only connected to a power outlet. The built-in fluid reservoir is enough for ~10 standard surfaces. If you wash once a year, you need to make a double or even triple run, spraying the cleaning agent in the path of the robot. Rag-slippers had to be changed every 3-4 windows (but this is because the windows have not been washed for a long time), in general, even very dirty ones leave strong stains. Cloths dry quickly, but the dirt from them is not completely gone even after washing in a typewriter. For the entire time of work - about 30 surfaces + 4 bathroom walls, the robot never fell off, sometimes it got stuck on the window elastic and began to squeak invitingly - apparently, it felt that it was starting to peel off and stopped its progress. In any case, I highly recommend this robot - it does an amazing job.
