When it comes down to a decision how to clean windows properly without using ladders, is usually a choice between a backpack or hose cart. Personally I’d prefer a hose cart, because it’s faster and easier setup. But in some occasions the backpack would be a better options as is a complete portable solution for Window Cleaning. The backpack is capable of holding up to 22 Litres and comes with an integrated carry handle. Simply adding pure water and we’re ready to clean windows.
