Because Of This, This Type Of Window Cleaning Machine Is Generally Manual, And Only A Few Parts Are Electric. The Slide Type Window Cleaning Machine In The Shape Of Sky Curtain Can Be Divided Into Two Forms: Cleaning Strip Sky Curtain And Cleaning Round Sky Curtain. The Principle Of Cleaning Strip Roof Window Cleaning Machine Is To Install A Track On Both Sides Of The Opening, And Move Back And Forth According To The Regulations When Walking, While Cleaning Circular Roof Is Mainly To Install A Rotation Axis At The Top Of The Roof, And Then Place A Circle Of Circular Track At The Bottom, And Do Circular Movement Along The Track When Walking.
