if using the harris clampless, for any awkward windows over conservatories, then i use the clamps, other than that they are slackened off for any other job.
on 2storie houses no other clamped pole will come close for speed of use.
its not just the lowering of the pole that is quick, extending it too is so fast, i can have the poe from closed to cleaning in 5sec on an upstairs window. then 2sec to come down.
also a good advantage is down the sides of houses cleaning landing windows, once the pole is up and you have no room to stand back then just release the hose at the base and let it come down a few inches or as much as you need without ever stopping cleaning.
i use ordinary non-reinforced 5mm clear pole hose.
