I must say right away - washing windows by hand is much faster. But - what for is it necessary when there is such an assistant ?! For half a day, I thoroughly washed 2 loggias, which I had not washed for two years. It is better to wash off the frames and the main dirt simply with a brush and a rag to more or less clean drops of water. But then run the robot for the final wiping and polishing - that's it. It is better to change the napkins for clean ones as they get dirty. In front of the robot, you can sprinkle a little cleaning agent, you can not from the kit, but not much, otherwise it will slip a lot in the wet at first. You can and should run it several times per window, depending on the stains. Final times are better with dry, clean wipes. Be patient, It works great from the remote control, the application completely duplicates the remote control, I installed it, tried it and deleted it. Be sure to hook the safety cable, and make room for electrical cords. On a plastic smooth ceiling, it loses orientation and spins in one square
