We see a lot of windows with "hard water" near Tampa Florida which usually means a sprinkler system or water hose hits the glass and minerals build up over time. I'm loving that tucker setup with pure water, but I'm kind of wondering if the regular water the other way might cause hard water since it's not pure water. You should be able to remove all screens and charge $5 each to rinse those off and put them back on.
water fed pole wont work on propertiesnthat havent been cleaned j a while. but the glass glo route is overkill. best practice is brush and squeegee first then maintain with waterfed.
