Long safety cord up to 5 meters. Clean cleaning. Thing is not specifically interchangeable in the household. not a pity for the money spent, the robot is worth it.
We are very glad that such a "BEETLE" is now responsible for the cleanliness of the windows in the house. I would have thrown off the video, the wife is simply delighted.
Its pros:
Facilitate the process of washing windows and mirrors. Convenient spray.
Its cons:
Noisy, as described. Sometimes it cannot complete the program, you have to stop it manually. Perhaps due to the lack of horizontal.
