Wanting to enter and stay updated with our world that advances faster than a roadrunner. This home robot which is able to clean many types of windows, or clean glass and will be totally neat. Like new! It is equipped with a large ring system that performs an empty dual pump suction, automatically and efficiently cleaning all the glasses. Fantastic, Congratulations..
