Here's my hat into the ring.
Recently, I've been curious to try out one of those electrostatic self-cleaning dusters from Eureka, so I bought one off of Ebay. The only thing is that I don't have a Whirlwind Litespeed, Boss Widetrack, or any other machine that uses one of them. So instead, I used my Nacecare Henry 160 with it. I took a spare Eureka wand that I had and attached it to the accessory, then put it in one of the rear tool slots. I also used a Shop Vac adapter that came with a car cleaning tool to allow the hose cuff to better fit into it. And guess what? It works!
As for the duster itself, it's a duster, not much to say on it. Unfortunately, the electrostatic part of it doesn't work that well. Idk if that's because of age or me not using it right (it was listed as being brand new, for the record). Apparently you're supposed to turn your Whirlwind on (assuming I had one) and let it spin inside the cup for 10-15 seconds, and that's what creates the electrostatic charge. However, it also wouldn't spin very freely, which I find stange considering that I'm certain that my Henry would have double the airflow and suction of any Eureka that this was meant to go to. Regardless, I had to spin it by hand while it got suctioned off. Luckily, on that note, the self-cleaning part works great, just as long as whatever dust on it isn't too sticky or gross.
Overall, I think it's nice little accessory, but it's not the greatest. It's good for scenarios where it'd be impractical to use a normal dusting brush attachment (i.e. for cleaning delicate or small things), but otherwise it's a duster, and has almost all of the drawbacks of one.
