I should mention that I've never used a blower on any vacuum ever for indoor use. I reach everywhere with crevice tools, dust mops and the new thin telescoping wand Swifter dusters. In desperate situations you can also wrap a glass cleaner or wet substanced rag or paper towel around yard stick or thin pole and clean dust out of those hard to reach areas.
The blower idea to me, would the dirt more airborne and not cleaned up.
For outdoor use work, I have a Kawasaki gas leaf blower that I love for blowing off anything from a dust layer on the car to leaves and debris on porches, etc. and even a little garage cleanout blowing everything out the open garage door!!
Hope this helps.
