It isn't the best thing ever, but it beats the hell out of doing the entire job myself. I've got one of those dyson mini-vacs for the corners (the kind that looks like a ray gun.) Yeah, it was expensive, but so is buying a long string of cheap dustbusters that don't do the job. I figured I only wanted to pay *once.*

And said spot-vac is how I'm going to deal with the little corners and edges; it's already what I have for dealing with scattered litter daily.

PS - there are also some extreme height differences between floors (for instance, new pantry is only 2 levels of linoleum; kitchen is about 4.) It doesn't gather well in those areas either, because as it climbs the threshold, its brushes lose contact with the edge.
