We have a project that requires cleaning a glazed brick wall (was the subject of a past thread), and I think we have the situation under control Except there are some high wall areas (12-18 ft high') on either side of high windows on stair landings.  These areas are not easily reached by ladders due to the precariousness of the situation, a cherry picker won't work and we can't build scaffolding.  Was wondering if anyone has used a device for reaching high areas like this without too much trouble.  We have a Whissper extractor but the wand isn't that long.  the wall has efflourescence in addition to standard grit and grime.  See photo below.  Thanks much, Baird
