I have high ceilings in my house and find it difficult to dust my lights and in the apexes. I have even resorted to tying a rag around my pool leaf scoop so that I could reach where I needed to. I was thrilled when a friend recommended this to me. It is nice and fluffy, catching every bit of dust and dirt and it telescopes so far! It extends and collapses very easily while still being strong enough to maintain the length you pulled it out to. I have not needed to rinse it yet as the dust has been falling out when I shake it.
