I wouldn't expect that it could catch all of the scrapings, especially if you were scraping something narrow like a balluster. It probably performs best as pictured, against a ceiling where the chips fall by gravity right into the nozzle.
Use a nice quiet shop vac like the Fein (or Festool) or you'll be reaching for earplugs after a few minutes of drone. And a HEPA filter seems like a must to make the containment idea work properly. A non-HEPA filter's gonna blow the finest particles into the neighborhood.
I'm a teensy bit skeptical.
Steaming or wet-scraping may be a better alternative for dust/chip control.

You are probably right. But then it might work on our popcorn ceilings. On boats they are doing the sides. I'll probably order it for his birthday (August 26) and report back after. It really does seem to be too good to be true, not a good sign. Yeah, Hepa filter a must for sure.
Its not a huge cash outlay, $30 plus $20 for 2 extra blades, not sure about shipping.

It does seem to be the perfect tool for popcorn ceilings! Hafta bookmark it.

We have one that we've used on the original wood storms and screens on our 1924 house. I've also used it on woodwork and window sills. It works well, especially on surfaces like woodwork that you can't bring to the basement or outside, and you don't want to create excessive steam and moisture in the living room.

On the wood storms, we use steam and standard scraping first, then the proscraper to get what's left after the surface has cooled, like in the video. I bought a couple of hose clamps to keep it attached to the vacuum. They helped a lot.

Here's a video on youtube.

Thanks Bluzette. I ordered it. I'll have dh read this thread and look at the video after I give it to him.

He used it for the first time yesterday and is very pleased. He is working on the soffit which has peeling paint. Very little has fallen on the dropcloth.
Yay! We just borrowed some scaffolding from a friend and put it up today, so that will make the work easier as well.
