My vacuum for the theater room has a wand with a variable valve adjustment (a smaller Dirt Devil). I wet the cone with a sponge, and then as I ramped up the vacuum level..it grabbed first one section pulling it out perfectly, I repeated this about 4 or 5 more times. You can tell it was ever pushed in. I'll post a picture after it dries, but voila it worked!
Thanks Audiohack!

I was careful to open the wand valve slowly and turned it on and off as I moved over the spot. The other places I had found about this method all concurred on one thing; dont place the hose over the cone with the vacuum on high; but try to use a proportioning valve. That said, the method works like a top.

As much as I like to help it wasn't me, thanks goes to BMWCCA.

Good idea for sure.

Great! I assumed anyone here would take normal care and precaution and proceed with the least invasive method first, ie. not running the vacuum full-out, but modulating the suction either with an adjustable control like yours, or by using an appropriate adapter tool on the vacuum. It goes without saying to bring the suction to the cone slowly and carefully while supporting the cone gently with your fingers. You don't want to suck the entire cone beyond its normal extension!

I used a mist-sprayer bottle instead of a sponge but its nice to know something else that worked. Once dry, there seems to be no change in the material as long as you've been moderate in how damp you made the dome.
