Traditional window cleaning services are hired not only by commercial establishments; they are also hired by estate managers looking after high-rise residential blocks. No matter how tall a building, you will rarely come across one with dirty glass facade or windows. Obviously, the owners of high rise commercial blocks as also residents in high rise buildings don't do their own cleaning - it would be virtually impossible for them to do so.
In fact, it is the prevalence of professional window cleaning services that encourage architects and civil engineers to think in terms of glass covered high rise construction. Without the professional window cleaning services, almost all the glass covered high rise constructions would remain dirty and dust covered presenting a very bleak view of the city.
One might be forgiven for wondering why Commercial Window Cleaning services is such a big deal. Ever tried to clean a window that is not at ground level? Even cleaning a window located on the first floor would be a challenge. Holding on to a ladder that might topple at any moment, balancing a small bucket of water between your feet or on some small ledge nearby and with the other hand trying to clean a window is definitely not everyone's idea of spending a relaxed weekend - there's every risk of landing up in a hospital that way.
Professional window cleaning service providers have specialized equipment such as sturdy extra tall custom built ladders with work platforms attached, they have special outfitted trucks carrying filtered water and high pressure pumps and hose pipes with special nozzles, they have custom made squeegees and brushes meant to clean and shine even the dirtiest windows, they have an onsite supervisor who inspects windows and makes sure they are free from scratches, streaks, hardened cement, dried paint and other blemishes. They have long ropes to lower staff and equipment. They have motorized work platforms that can be attached tso roofs and lowered all the way to the ground floor. Finally, they have trained personnel who aren't scared of heights. It's a tough combination to beat.
Of late Commercial window cleaning services providers have also added a new tool to their already impressive collection - the robotic window cleaner. These are wired/remote controlled vacuum cleaner like devices that can crawl up and down on a continuous window facade. They use suction properties of specialized wheels or belts to stick to and move up or down on vertical glass. A long hose pipe carrying filtered water is attached to the robot and it has built in tanks for cleaning fluid and also carries attachments such as scrubbers or squeegees. Equipped with these arsenals of tools, professional window cleaning services have come a long way since the mid-sixties and seventies when cleaning crews had to be lowered from rooftops via ropes.
