Window Robots began sourcing the latest window robots for specific jobs when a family member found herself in a high rise apartment looking out of a dirty window on the fourth floor that was impossible to reach from the outside. After trying many different models on the market, we requested the Rozie 1200 as not only was she powerful enough to hold suction , but was slim enough to fit between the small gap in between the safety hinges . With a safety harness in tow and our specialized cleaning solutions, Rozie, with her 5 stage cleaning method, removed black mold, 2 spiders and their webs and acid rain build up. The window looked fabulous and Window Robots Ltd have never looked back since. Window Robots Ltd now supply the Rozie 1200 for hard to reach windows, Tobi for BIG Windows and the TOBi2 for commercial windows. These amazing robots are an invaluable asset in the home and we believe once you get one, you will wonder how you ever got along without one. We deliver to NZ and now also operate in NSW Australia.
