Just read this entire thread, took some time, boy is it long.
I am with NWH with his views on this Harris pole. It's far too whippy for my liking. I would never buy one despite them being excellent value for money at next to nothing. The reason I would never buy one has got nothing to do with the pole being whippy but for the simple reason 'twist lock' clamps agravate and flare up my arthritus- so for me it's a big no, no, end of story.
As for Groundhog's speed: there's nothing wrong with working at that speed on maintenance cleans providing you use enough water flow to match. The higher the water flow, the quicker you got to work. I too, only rub, not rinse on translucent (bathroom) windows as you only have to loosen the dirt and the weight of the water will pull the dirt down the glass. If there's any dirt left it will be miniscule and won't be noticeable from inside. The only thing you got to watch out for rinsing too quickly is splash backs from gritty tiled concrete sills that splash back onto the glass. Answer is to run a final rinse on the last 2inches of glass at the bottom before moving on to the next pane of glass.
When I clean a window, I always rub the top of the frame, then the sides, then any top openers and rinse them at the same time before rubbing the remaining glass.
Rinsing, I start from the top of the glass, (not the frames) and work my way down to the bottom ensuring I have a nice sheeting action coming down the glass with my brush. If the rinsed water sheets easily, the glass can be cleaned in seconds as I'll let the water run down the glass and lift my brush off, turning the water flow off half way down. If it doesn't sheet, then I'll make sure the brush pulls the water and gritty particles down to the bottom of the pane and finish with a wipe along the sill providing it's PVC.
I am not camera shy and if anyone has a camcorder as I don't posses one, they are welcome to film me cleaning windows with my my Facelift or SL-X poles and post them on here for Groundhog to compare the difference between using a rigid pole and a whippy pole. I think it would be interesting to hear constructive critism and for someone to point out any bad habits I've developed.
