A poorly translated manual cost us 2 d time until the device was last used. Why always have to manually readjust the magnetic holding mechanism in a robot, is incomprehensible. The unit leaves while cleaning abundant streak, especially by the wheels of the holding unit. In addition to the cleaning unit always remain Fusselabdrücke at the point where one removes the device after the stop. Triangular windows can not be cleaned without supervision, manual control is needed here. I would buy the unit again, here a little on the technology development is probably necessary.
