It is very difficult to remove accumulated dust on hills, ceiling fans, etc. With the right vacuum cleaner, this adjustable nozzle helped a lot. Despite many adjustments, the joints seem to "loosen up" a bit after a few weeks. It takes a bit of skill to tilt the brush head at the end of a 10ft pole and apply just the right amount of pressure on the brush. If the pressure is too high, the joints can now move independently. With a high-quality vacuum, the brush head offers enough suction power for our purpose. The brush isn't stiff enough to pick it all up, but it picks up visible amounts of white dust, bugs, cobwebs, etc. from the tree trunks. I wish the joints were a little tighter.
