I thought this tool would be a big waste of money. You have to haul your garden hose around to wet your windows...personally I would have to go buy another 100 feet of hose to be able to do all of my windows. It is much easier to climb a ladder with a bucket and sponge than it is to drag around the garden hose. The windows I could reach didn't get any cleaner with this product than my usual way of cleaning them.
