To prevent caking or clumping of dusts in the Dustick Duster you can add a small pebble or marble. Also be sure to shake occasionally and not leave dust in the cannister when not in use.
The Dustick Duster is manufacturered by a US company called Advantage Products.
Dust will fall to the bottom of the cannister on the Dustick Duster (with 21-foot reach). A handle at one end of the pole is used to pump air all the way through the extension to the dusting canister and tip on the other end, causing dust to be expelled. We do recommend filling only halfway.
We would recommend that you do not fill it any more than half full. Unfortunately, putting a stone and/or penny in the bulb will help keep the dust from clumping too fast but you will still need to shake the duster occasionally.
The Dustick Kit comes with 4 x 4 foot extension poles, a dust canister and dusting tip, pump handle and a canvas carrying bag. We, also, carry the Dustick Deluxe Kit w/ Duster Top, Aerosol Top and Scraper Tool which includes 4 x 4 foot long poles, dust canister, dusting tip, pump handle, aerosol tool, scraper tool, and canvas carrying bag.
The manufacturer does not recommend using additional poles with the Dustick Duster (with 21-foot reach) as the weight of the poles can cause the duster to break.
Please view our How to Use the Dustick Duster Video showing how to assemble and use the duster.
You could be using too much dust in the cannister or the extension tip could possible be clogged. We recommend cleaning the extension tip of any buildup or dust residue and also, only fill the cannister about ½ way dust. Overfilling the cannister will not allow the air to blow the dust through the tip.
The Dustick Duster (with 21-foot reach) is operated by the handle at one end of the pole being used to pump air all the way through the extension to the dusting canister and tip on the other end, causing dust to be expelled.
