Winbot 950 is an innovative window cleaning robot for glass surfaces. Modelled after its predecessor and featuring a two-part system; the moving unit and cleaning unit of this model operate independently from one another. The smart planning system does the cleaning in a serpentine path, which highly improves the efficiency. Based on an air-compressor adsorption principle, the device can start its work immediately. Bumpers installed all around the cleaning unit make it more sensitive for obstacles.
