I'm after recommendations for a hose attachment window washer that will do first floor windows. Preferably under £50 if such a thing exists. We have decking at the back and I really don't want to go up on a ladder as I'm a bit unsteady due to plantars fasciitis. I don't want to pay a window cleaner as all of them round here will seem only willing to do it if you sign up to have them cleaned every month which I don't want to do
